In this research cellulose nanofibers (CNF) were successfully extracted from rice straw through a chemomechanical method and then mixed with urea-formaldehyde (UF) adhesive for the production of medium density fiberboard (MDF). The industrial grade liquid urea-formaldehyde (UF) resin with formaldehyde: urea molar ratio of 1.15 was modified by adding 0.5, 1.5 and 2 wt \% of nanofibrillated cellulose (CNF) based on UF resin solids. The morphology, gel time, viscosity, and the non-volatile solid content of the modified UF adhesive were investigated. Formaldehyde emission and some mechanical properties modulus of rupture (MOR), modulus of elasticity (MOE) and internal bond strength (IB)) of the resulting MDF panels were measured. Solids content and viscosity of the UF adhesive decreased while gel time increased by mixing CNF with the resin. The formaldehyde emission of the panels made with UF containing CNF was lower than that of the panels made from neat UF while MOR, MOE and IB values increased by increasing the CNF content in the panels.

In building environments, several research on dynamic moisture storage in hygroscopic building materials has improved interest in moisture buffering capacity of bio-based materials and demonstrated the potential of these materials to improve thermal comfort and buildings energy consumption. This paper presents an investigation, which aims to compare the hygroscopic behavior of different bio-based materials to identify their hygric proprieties. For this, an experimental facility is used to measure the moisture buffer value (MBV) for different categories of building materials. Thereafter, a dynamic simulation has been carried out by using TRNSYS software in order to evaluate heating and cooling loads. The results showed that the wood-cement composite still has excellent moisture regulator when compared to wood panels or fibrous materials. It has a buffer capacity superior to 3 [g/m(2).\% RH] very close to that of wood fiber panels. The simulation results of the different cases showed that the insulation reduces significantly total energy demand, but it does not lead heat evacuation in the summer season. Thus, from this study, it can be concluded that a natural ventilation mechanism is recommended to improve energy efficiency in the building.

Wood-wood connections, widely used in the past, have been progressively replaced by steel fasteners in timber constructions. Currently, they can be manufactured and implemented more efficiently thanks to digital fabrication techniques. In addition, with the emergence of new timber plate engineered products, digitally produced wood-wood connections have been developed with a strong focus on complex free-form geometries. The gained knowledge through research and building implementations have pushed the development of more standardized structural elements. As a result, this work presents a new concept of building components using through tenon connections based on the idea of transportable flat-packs directly delivered and assembled on site. The main objective of this research is to develop a convenient calculation model for practice that can capture the semi-rigid behavior of the connections and predict the effective bending stiffness of such structural elements. A case study is used as a reference with three large-scale slabs of a 8.1 m span. Bending and vibration tests are performed to study the mechanical behavior and assess the proposed calculation method. The results show the high influence of the semi-rigid behavior of connections on the bending properties and, therefore, on the serviceability limit state. The model is in good agreement with the test results, and further improvements can be made regarding the local behavior of the connection. This study demonstrates the feasibility of the proposed construction system and the applicability of the developed calculation model to design practice.

In this study, a three-dimensional (3D) printing filament prepared from poly (lactic acid) (PLA) and acetylated tannin via a twin-screw extruder was reported. The impact of acetylated tannin loading content on the final properties of the resulting composite materials and their 3D printability were investigated. The experimental results indicate that PLA can be compounded with up to 20 wt\% acetylated tannin without any obvious deterioration in the tensile property. The resulting composites acquired better degradation rate in aquatic system compared with neat PLA, especially in alkaline medium. Moreover, all composites are printable and showed generally good printing quality with brown color, however, this is limited to temperatures reasonably below 220 degrees C to avoid printing defects, especially at high loadings of acetylated tannin.

Studying the cutting forces during wood machining by a removal process is crucial to ensure high surface quality, maximum precision and to minimize chattering phenomena. Currently, industrial tasks and research works concerning using serial robots for wood machining are rare, which can be explained by the low stiffness of such machines. High cutting forces with low machine rigidity undeniably disturb robot behaviour during wood machining. The machined surface quality and machining process performance will be degraded, causing toolpath deviation and dimensional errors. Therefore, operating time and cost will be high. To overcome this issue, the present research focuses on how to ameliorate robotic wood machining by studying the link between cutting forces and accuracy while machining wood using a serial robot. This study deals with three major constraints, low robot accuracy, low stiffness and high cutting forces.

Vacuum technology was applied to the hot-pressing technology of plywood production with phenolic resin (PF). For plywood with the same number of layers, veneers were hot-pressed with conventional and vacuum hot-pressing processes respectively at the same hot-pressing time. Varying layers (3, 9 and 15-layers) and spread quantities (220 g m(-2), 260 g m(-2), 300 g m(-2)) were applied. Heat transfer performance of the assembly, polymerization extent of PF, and bonding quality of plywood were examined by thermocouple and humidity sensors, Fourier transform infrared spectroscopy (FTIR), fluorescence microscope and bonding strength measurement. The results indicated that, compared to conventional hot pressing, the temperature of the central layer of the assembly vacuum hot-pressed was significantly increased by about 20-30 degrees C and the adhesive cured more quickly. The hot-pressing method had a significant influence on the bonding strength of plywood, with an enhancement of the bonding strength to wood failure ratio of 48.37\% and 33.55\%, respectively. The adhesive between adjacent laminates formed a continuously dense layer with more connection points, leading to excellent mechanical meshing and high bonding quality. In addition, vacuum hot pressing can eliminate the influence of adhesive position on bonding strength and make the mechanical properties of plywood tend to be uniform in thickness direction. Under the experimental conditions, the variable energy cost of 15-ply plywood with 1 m(3) produced by vacuum hot pressing was 3.83\% less than that of conventional hot pressing, and the plywood could still maintain good bonding strength at low spread quantity.

The research also presented the environmental impact and economic analysis of using the dryer. Performance evaluations show that at collector efficiency of 20.81\%-21.89 \%, the developed solar dryers can save between 10-21hrs of drying time in drying 5 mm thick plantain slices to 15 \% moisture content from initial moisture content of 66 \% w.b when compared to drying under the open sun. The improvement potential ranged from 0.036 to 20.6W while the waste exergy ratios and sustainability index ranged from 0.38-0.55 and 2.3-6.11 respectively. Application of the solar dryers can save between 44-3074 of CO2 entering the atmosphere per year while 2.94 to 205.43$ could also be saved at 10-100\% rate of usage when compared to diesel fired dryer. The total energy consumption for drying ranges between 5.52 and 35.47 MJ, while the specific energy consumption ranged from 4.3 to 26.2 kWh/kg. The exergy efficiency ranges from 5.6-95.13 \% during the sunshine hours.

The rise of digital fabrication has increased the use of wood-wood connections inspired by traditional carpentry in modern timber constructions. With recent developments on standard construction systems, the mechanical behavior of such joints for in-plane loading configurations is an essential parameter for the structural design. However, only few design guidelines exist on this topic in building codes such as Eurocode 5 and research has been mainly focused on the rotational behavior, which is important for free-form structures. Therefore, this work presents an experimental campaign on the load-carrying capacity of digitally produced through tenon connections for commonly available engineered timber products such as oriented strand board, laminated veneer lumber, and multiply solid wood panels. Shear and compression failure modes were studied and two test setups were developed. The scope of the study was limited to five different materials, a grain orientation parallel to the joint, and three different tenon lengths. The test results showed significant differences between the product specifications given by manufacturers and real performances observed for oriented strand board and cross laminated timber, while laminated veneer lumber had more accurate specifications. Nonetheless, a spreading of the compression strength was highlighted only for the OSB material and was also observed for the shear strength of laminated veneer lumber specimens. The existing Eurocode 5 guidelines generally underestimated the load-carrying capacity of the connections by 25\% and only the capacity of oriented strand board connections was overestimated. Finally, the study demonstrates that different design approaches can be defined according to the material employed in through tenon connections. Design diagrams based on tests are preferred for materials with a high variability between product specifications and real performances while design criteria from building codes can be applied for the others.

In this study, in order to improve the anti-fungal performance of wood material, a facile, efficient and eco-friendly method was proposed for wood modification under the synergistic effect of silver particles and high voltage electrostatic field (HVEF) treatment. Poplar wood, a vulnerable to decay species, was hot-pressed by silver electrode plates and exposed simultaneously to HVEF. The chemical characteristics and anti-fungal performance of treated wood were investigated in details. Under HVEF treatment, silver particles were triggered to different oxidized forms and bound with polar groups in the wood cell wall. Decreased O/C element ratio and -OH groups and increased C-H and C=O bonds in treated wood were observed by the X-ray photoelectron spectra (XPS) and fourier transform infrared (FTIR) spectroscopy. After 24h of HVEF treatment, high concentration (10.71\%) of well-distributed silver particles appeared in mapping graphs. Laboratory anti-fungal tests showed that mass losses of treated wood samples decreased significantly (\<1\%) after exposing to rot fungi. The highest leaching percentage of silver in treated samples was 3.94\%. These results indicated that the synergistic effect of silver particles and HVEF treatment enhanced the fungal-resistance performance of wood. Moreover, this approach could be regarded as a facile, efficient and eco-friendly modification to broaden the outdoor-use potential of wood.

The present study reports the preparation of chemically activated carbons (PAC and ZAC) from apricot stones using phosphoric acid and zinc chloride, respectively. The potential use of the prepared carbons, as adsorbents, and the effect of chemical activation on the surface properties and adsorptive mechanism of nitrobenzene (NB) were investigated. The physicochemical properties of the obtained materials were characterized by Nitrogen adsorption-desorption isotherms, Scanning Electron Microscope, FTIR Spectroscopy, EDX analysis, Boehm titration, and pH of zero charge. The results show that the prepared samples present high apparent surface areas (1,382 and 1,111 m(2)/g for PAC and ZAC, respectively) and pores volumes with the presence of various functional groups. It was found that pseudo-second model was the most suitable for the fitting of the experimental kinetic data and the intraparticle diffusion was not the unique rate-controlling stage. The adsorption isotherms were well described by the Langmuir and the Freundlich models. According to the Langmuir model, the maximum adsorption capacity of PAC and ZAC were about 476.2 and 490.2 mg/g, respectively. The thermodynamic parameters showed the spontaneity, the exothermic nature, and the decrease in the randomness of the adsorption of nitrobenzene. Chemical regeneration showed that the prepared samples could be used for four time desorption-adsorption cycles with good efficiency for NB removal, indicating that the prepared carbons could be used as a low-cost alternative to commercial activated carbon for the removal of nitrobenzene from wastewater.

In this work, beech wood has been submitted to fractionation and hydrothermal liquefaction in order to produce fermentable carbohydrates. Fractionation either by ethanol organosolv or by sodium chlorite/acetic acid (SC/AA) treatment allowed obtaining delignification yields of 50 and 91 wt.\% respectively. The recovered pulps were then submitted to liquefaction in hot-compressed water (HCW). Three temperatures were studied: 180, 200, and 220 degrees C during 2 h. The same experiments were conducted on untreated beech and model cellulose (Avicel PH-101). Product yields and total carbohydrates were determined. The liquefaction products, i.e., solid residue, water-soluble compounds, and permanent gas, were analyzed respectively by X-ray diffraction (XRD), high-performance anion-exchange chromatography with pulsed amperometric detector (HPAEC-PAD), and gas chromatography (GC). SC/AA treatment allowed a high recovery of hemicelluloses and for this reason, xylose content was significantly higher than for the organosolv pulp. The maximum yields of total carbohydrates (based on the initial carbohydrates in wood), found when the liquefaction temperature was 220 degrees C, increased from 9.0 wt.\% for the raw beech to 13.5 and 33.7 wt.\% for the organosolv and SC/AA pulps respectively.

Skeletal defects resulting from trauma and disease represent a major clinical problem worldwide, exacerbated further by global population growth and increasing number of elderly people. As treatment options are limited, bone tissue engineering opens the possibility to grow unlimited amount of tissue products with enhanced therapeutic potential for the management of clinical cases characterized by severe bone loss. Bone engineering relies on the use of compliant biomaterial scaffolds, osteocompetent cells, and biologically active agents. In this pinion paper, we drive the attention to a new application of a natural material: Tannin. Among others materials, porous tannin spray-dried powder (PTSDs) has approved to human use. We can use PTSDs as reconstructive materials with low cost, biocompatibility and potential ability to be replaced by bone in vivo. In this study macro PTSDS scaffolds with defined geometry, porosity and mechanical properties could be manufactured using a combination of casting technology and porogen leaching, by mixing PTSDs and hydroxyapatite (Ca10(PO4)6 (OH)2 with polyethylene glycol macro particles. The expected results show that the scaffolds developed could support attachment, long-term viability and osteogenic differentiation of human induced pluripotent stem cell-derived mesenchymal progenitors. The combination of select macro porous PTSDs scaffolds with patient-specific osteocompetent cells offers new opportunities to grow autologous bone grafts with enhanced clinical potential for complex skeletal reconstructions.

The diversity and distribution of specialized metabolite gene clusters within a community of bacteria living in the same soil habitat are poorly documented. Here we analyzed the genomes of 8 Streptomyces isolated at micro-scale from a forest soil that belong to the same species or to different species. The results reveal high levels of diversity, with a total of 261 biosynthesis gene clusters (BGCs) encoding metabolites such as terpenes, polyketides (PKs), non-ribosomal peptides (NRPs) and ribosomally synthesized and post-translationally modified peptides (RiPPs) with potential bioactivities. A significant part of these BGCs (n = 53) were unique to only one strain when only 5 were common to all strains. The metabolites belong to very diverse chemical families and revealed that a large diversity of metabolites can potentially be produced in the community. Although that analysis of the global metabolome using GC-MS revealed that most of the metabolites were shared between the strains, they exhibited a specific metabolic pattern. We also observed that the presence of these accessory pathways might result from frequent loss and gain of genes (horizontal transfer), showing that the potential of metabolite production is a dynamic phenomenon in the community. Sampling Streptomyces at the community level constitutes a good frame to discover new biosynthetic pathways and it appears as a promising reservoir for the discovery of new bioactive compounds.

Over the past few years, nanocellulose (NC), cellulose in the form of nanostructures, has been proved to be one of the most prominent green materials of modern times. NC materials have gained growing interests owing to their attractive and excellent characteristics such as abundance, high aspect ratio, better mechanical properties, renewability, and biocompatibility. The abundant hydroxyl functional groups allow a wide range of functionalizations via chemical reactions, leading to developing various materials with tunable features. In this review, recent advances in the preparation, modification, and emerging application of nanocellulose, especially cellulose nanocrystals (CNCs), are described and discussed based on the analysis of the latest investigations (particularly for the reports of the past 3 years). We start with a concise background of cellulose, its structural organization as well as the nomenclature of cellulose nanomaterials for beginners in this field. Then, different experimental procedures for the production of nanocelluloses, their properties, and functionalization approaches were elaborated. Furthermore, a number of recent and emerging uses of nanocellulose in nanocomposites, Pickering emulsifiers, wood adhesives, wastewater treatment, as well as in new evolving biomedical applications are presented. Finally, the challenges and opportunities of NC-based emerging materials are discussed.

Eucalyptus trees have been adapted to the Tunisian climate. Now, they need to be economically valued. Tunisian Eucalyptus have great technological properties allowing us to use them as wooden material. However, there is large variability in the natural durability between heartwood Eucalyptus spp. The wood sustainability assessment provides reliable parameters to predict the service life of wood-based products. This study aimed to evaluate the wood deterioration of four North Tunisian fast-growing Eucalyptus spp. (Eucalyptus maidenii, Eucalyptus saligna, Eucalyptus camaldulensis and Eucalyptus gomphocephala) exposed to basidiomycetes (Coniophora puteana and Trametes versicolor) and termite (Reticulitermes flavipes) attacks. Among the four Eucalyptus woods, Eucalyptus gomphocephala presents the highest decay and termite resistance. The four Eucalyptus wood species are classified as very durable against fungal degradation and durable against termite attacks, expect for Eucalyptus saligna which is classified as sensible against termites. The natural durability of Eucalyptus seems to be mainly caused by extractives, and a lot of compounds are involved. Antifungal and anti-termite properties of these compounds were put in perspective with the natural durability of wood. Gas chromatography-mass spectrometry (GC-MS) analyses highlighted that Eucalyptus durability is mostly governed by gallic acid, fatty acid glycerides, fatty acid esters, phenolic compounds, sitosterol, catechin and ellagic acid.

The objective of this paper is to model a natural convection mix-mode solar dryer (NCMMSD) for drying agricultural products in an environment with short sunshine duration. The solar dryer was used to dry red chilli and was operating under the climate of the coastal area of South Eastern Nigeria characterized by low solar radiation intensity with a short duration of sunshine hours. The model took into consideration the thermophysical properties of the drying air and dried red chilli. The simultaneous heat and mass transfer equations were solved using the fourth-order Runge-Kutha method. The numerical solution allows for the determination of temperature and relative humidity of drying air at different points within the dryer as well as the moisture profile of the dried product. The experimental values of moisture ratios, temperature, and relative humidity during the mix-mode solar drying process with and without NaCl were used to validate the proposed model. Numerical simulation results were in close agreement with experimental results. The present model can serve as good reference bases to explain the drying phenomenon of mix-mode solar drying of other agricultural products when necessary thermophysical properties of these products are known. Using this model, the potential of mitigating gross fossil (coal) CO2 in Africa is annually estimated to 1280148 tons of CO2.

The compatibility issue between poly(lactic acid) (PLA) and tannin is a big challenge for preparing PLA/tannin biocomposites with enhanced properties. In this work, composites with enhanced properties have been accomplished using an efficient one-step reactive extrusion method with the help of methylene diphenyl diisocyanate (p-MDI) or 3-aminopropytriethoxysilane (APS). The extent of compatibility achieved via the one-step was evaluated by tensile, morphological, rheological, and thermal properties. The obtained results indicated that the adhesion promoters, especially p-MDI, contributed efficiently to an improved tensile behavior of the resulting composites with a tough tensile-fracture surface compared with incompatibilized PLA/tannin composite. Moreover, these composites displayed a plateau-like rheological behavior, enhanced complex viscosity, higher melting and thermal degradation temperature. This approach can be potentially adapted to other PLA/biopolymers composite systems.

Key message Total bark extractive content increases at positions higher in the trunk ofAbies albaMill. trees. The greatest proportions of bark polyphenolic extractives are found in the lower section of the trunk, below the crown. Context The bark of commercially grown softwood trees is a potentially valuable source of secondary metabolites including polyphenols such as tannins, used in the manufacture of adhesives and resins. There is little information about how the yield and composition of bark extracts vary longitudinally within trees and with respect to the presence or absence of branches. Aims We examined the variability of bark secondary metabolites in the softwood Abies alba both longitudinally within trees and among trees at specific sample heights. The aim was to determine whether specific bark fractions within this species contain more extractable secondary metabolites than others. Methods Eight trees of A. alba were harvested, and up to 13 discs were cut along the trunk from 30 cm above the ground to where the trunk was only 10 cm in diameter. Milled bark was extracted with water:ethanol (1:1) using an accelerated solvent extractor and the dry yield calculated. Extract composition was examined by liquid chromatography followed by mass spectrometry. Results Total extract yield increased from the base of the tree towards the top. The yield of the most abundant polyphenolic compounds decreased from the base of the tree towards the top, indicating the total extracts included compounds that were not detectable with the chromatographic method used. Conclusion Although extract yield is highest at the top of the tree, the composition of the extracts indicates that compounds with known marketable value, and present in detectable proportions, are found at the base of the tree.

The general objective of this work was to evaluate the quality of the little-known tropical woods of the Congo Basin, particularly Coula edulis, while looking for new biocidal products. The natural durability of the hazel tree of Gabon Coula edulis versus basidiomycete fungi was evaluated with native and extracted samples of heartwood against brown rot (Rhodonia placenta and Coniophora puteana) and white rot (Trametes versicolor and Pycnoporus sanguineus) fungi. The results showed that non-extracted samples were more durable. Fungal growth inhibition tests using different concentrations of extractives confirmed the fungicidal effects. Percentage of the different wood polymers and GC-MS analysis of wood extractives were carried out to examine correlations between durability and wood chemistry. Natural durability of Coula edulis could be explained by the unusually high lignin content and the presence of high amounts of polyphenols like gallic and ellagic acids and tannins. Coula edulis could therefore be a local alternative to help alleviate wood shortages in Gabon.

The natural durability of wood species, defined as their inherent resistance to wood-destroying agents, is a complex phenomenon depending on many biotic and abiotic factors. Besides the presence of recalcitrant polymers, the presence of compounds with antimicrobial properties is known to be important to explain wood durability. Based on the advancement in our understanding of fungal detoxification systems, a reverse chemical ecology approach was proposed to explore wood natural durability using fungal glutathione transferases. A set of six glutathione transferases from the white-rot Trametes versicolor were used as targets to test wood extracts from seventeen French Guiana neotropical species. Fluorescent thermal shift assays quantified interactions between fungal glutathione transferases and these extracts. From these data, a model combining this approach and wood density significantly predicts the wood natural durability of the species tested previously using long-term soil bed tests. Overall, our findings confirm that detoxification systems could be used to explore the chemical environment encountered by wood-decaying fungi and also wood natural durability.

Energy and buildings are increasingly becoming subjects for investigations, especially for the indoor air quality domain coupled to energy demand. The physics of fluids flowing inside enclosures bring basic models to understand and build better schemes. This paper is devoted to studying ventilation strategies in regards to Indoor Air Quality (IAQ) and energy efficiency in floor refreshing houses. A room model is considered in a simplified level, as a cavity heated on the external sidewall and cooled on the bottom ground surface. The external air injector is at variable positions and interacting with the needed cooling power; the air quality (mixing ability) and thermal comfort are also studied. The cooling efficiency inside the considered volume and the average air temperature are analyzed for a given temperature difference characterizing the natural convection level (Rayleigh number, Ra = 10(6)) and a horizontal ventilation (moderate Reynolds number Re = 10(2)). An obtained complex flow structure indicates that the natural convection and the forced flow (ventilation) act directly on the resulting patterns, mixing ability, heat exchange which in a straight line affect the thermal comfort and in fine the energy cost (cooling requirement).

In this work, the effect of particle size and severity factors was investigated to find the optimum condition of steam explosion pretreatment on xylan recovery of beech wood. The beech wood particles with sizes of 0.16, 1, or 2 mm were steamed at 150-210 degrees C for 2.5-15 min before an explosive decompression. The results showed that the maximum xylan recovery was about 10\% w/w wood with low concentrations of the inhibitors, which were obtained when the particle size is 1 mm and R-0=3.65 (190 degrees C, 10 min). The smallest particle size may result in overcooking of biomass, leads to easily and high degradation of hemicelluloses sugars, whereas the largest particle sizes may result in incomplete autohydrolysis in biomass and lower extractability of hemicelluloses sugars. The obtained optimum condition for xylan recovery will improve the subsequent utilization (such as in food industry and other chemical products), prior to subsequent transformation of steam explosion pretreated wood (bioethanol and pellet).

The goal is to produce cottonized hemp fibers with improved thermal stability. It was first found that the fine hemp fibers produced from technical non-retted hemp fibers by steam explosion exhibited an enhanced thermal stability. An efficient and low-cost process was developed using a mixture of urea/etidronic acid in aqueous solution in order to achieve a high phosphorus content and produce flame retardant fibers by chemical grafting. ICP, P-31 and C-13 NMR, SEM, thermogravimetric, Pyrolysis-Combustion Flow Calorimetry analyses and a flame test were used to characterize the grafted fibers. Fibers modified with relatively high P and N contents have been produced (approximate to 6 wt \% and approximate to 4 wt \% respectively) but lower grafting rates (P approximate to 0.5 \% and N approximate to 0.35 \%) are sufficient to produce non-flammable fibers. A synergistic effect between N and P has been proposed to induce the formation of a stable char.

This paper presents experimental and numerical investigations on the vibrational serviceability performance of novel adhesive free engineered wood products (AFEWPs), namely adhesive free laminated timber beams (AFLB) and adhesive free cross-laminated timber panels (AFCLT), assembled through thermo-mechanically compressed wood dowels (CWD). The laminations composing the AFEWPs are made of oak timber while the CWD are made of spruce. The experimental modal analyses were carried out under free-free conditions using a hammer impact. Natural frequencies, mode shapes, and damping ratios were assessed experimentally. In addition, similar glued beams made of oak timber (conventional glulam) were manufactured and tested for comparison purpose. A predictive 3D FE model was developed and validated by comparison against experimental data and then used to predict the vibrational behavior of a realistic flooring system made with AFCLT panel and measuring 4.5 m x 5.5 m. The predicted FE results were discussed with regard to the Eurocode 5 vibrational serviceability design requirements showing acceptable vibrational performance. The variability level of the results for the AFEWPs is also studied and discussed.

Drying is a simultaneous heat and mass transfer processes. Drying kinetics is determined by both internal properties and external drying conditions. In this study, two important drying kinetics parameters of onions i.e. effective water diffusivity and relative activation energy of reaction engineering approach (REA) are determined. The generated parameters are used to model thin layer drying of onion at different temperatures (40, 50, 60, and 70 degrees C) and relative humidity of 20\%. The effective water diffusivity is in the range of 2.8x10(-10)m(2)s(-1) and 8.1x10(-10)m(2)s(-1). Unlike the diffusivity, the relative activation energy of the REA is independent on drying conditions and thus the latter approach requires less effort in generating the transport properties. The transport parameters can be applied for assisting in designing dryer units and evaluating the performance of existing dryer units.

Equilibrium moisture content (EMC), net isosteric heat of sorption (NIHS), net entropy of sorption (NES) and standard free energy of Gibbs (SFEG) of Triplochiton scleroxylon (obeche) and Sterculia rhinopetala (lotofa) are modeled using Nelson\&$\#$39;s sorption isotherm model. Experimental data are determined using a dynamic vapor sorption apparatus. Air relative humidity is ranged from 0 to 90\% and two air temperatures (20 degrees C and 40 degrees C) are used. Experimental data of EMCs obtained from adsorption and desorption for the mentioned woods were compared with the predicted results using Nelson\&$\#$39;s sorption model by the application of the same operating conditions (i.e. temperatures and relative humidity conditions). The results showed that the predicted ones were in good agreement with the experimental data, when the relative humidity varied from 1.2 to 90\%. Both adsorption and desorption phase presented a mean relative errors value inferior to 6.3\%. The parameters that define the sorption isotherm varied with the wood type and the sorption mode. Thus, Nelson\&$\#$39;s sorption isotherm model is a useful tool that can be used for prediction of the moisture change in wood under different environmental conditions and for predicting indirectly the thermodynamic parameters such as NIHS, NES and SFEG. In adsorption and desorption mode, the NIHS are estimated using Clausius-Clapeyron\&$\#$39;s equation. The desorption values were higher than the adsorption ones. NIHS versus EMC varied exponentially and the parameters of the function were presented variable with the sorption mode and the wood type. The total energy that we needed to extract and evaporate all bounded water is 12,398.6 J/mol for obeche and 11,627.7J/mol for lotofa. The total energy that we needed to condense and fix all bounded water taken from the state vapour is 11,829.34 J/mol for obeche and 11,379.39 J/mol for lotofa. Water molecules are more mobile during desorption than adsorption in the case of obeche. In the case of lotofa, these molecules are more mobile during adsorption. SFEG is higher in desorption than adsorption and it is influenced by species and less by the temperature. When the temperature increased, the SFEG increased as well. At low values of EMC, NIHS and SFEG are higher and decreased with the increase of EMC until reaching the fibre saturation point.

This study aimed to investigate the effect of the maturation process of sweet marjoram (Origanum majorana L.) on essential oil composition, the phenolic profile of ethanolic extract and their antioxidant capacities. The essential oil composition was studied at three stages of maturity by GC-MS. Thirty compounds were detected representing 100\% of the total essential oil. p-Menth-1-en-4-ol was the major compound (37.15-76.94\%) followed by cyclohexanol-3,3,5 trimethyl (5.41-15.99\%) and alpha-terpineol (0.94-11.34\%). During the maturation process, an accumulation of oxygenated monoterpenes was observed. The phenolic composition was studied using matrix-assisted laser desorption/ionization time of flight. The analysis showed the presence of short flavonoid monomers at all stages of maturation. The antioxidant capacity of ethanolic extracts and essential oils was evaluated using the DPPH assay, iron chelating power and reducing power assay. The highest phenolic content and antioxidant capacity were found at flowering stage. These findings on essential oil composition, phenolic profile and antioxidant capacity of O. majorana at three different stages of development provide more information on how these secondary metabolites are accumulated.

The caryopses of barley become firmly adhered to the husk during grain development through a cuticular cementing layer on the caryopsis surface. The degree of this attachment varies among cultivars, with poor quality adhesion causing \"skinning\", an economically significant grain quality defect for the malting industry. Malting cultivars encompassing a range of husk adhesion qualities were grown under a misting treatment known to induce skinning. Development of the cementing layer was examined by electron microscopy and compositional changes of the cementing layer were investigated with gas-chromatography followed by mass spectroscopy. Changes in gene expression during adhesion development were examined with a custom barley microarray. The abundance of transcripts involved early in cuticular lipid biosynthesis, including those encoding acetyl-CoA carboxylase, and all four members of the fatty acid elongase complex of enzymes, was significantly higher earlier in caryopsis development than later. Genes associated with subsequent cuticular lipid biosynthetic pathways were also expressed higher early in development, including the decarbonylation and reductive pathways, and sterol biosynthesis. Changes in cuticular composition indicate that lowered proportions of alkanes and higher proportions of fatty acids are associated with development of good quality husk adhesion, in addition to higher proportions of sterols.

In this work wood-to-heat chains are assessed on environmental and micro-economical aspects. Wood combustion produced various minor pollutants, which should be considered in life cycle assessment For this purpose different wood combustion processes have been modeled under Aspen Plus (R) software in order to assess pollutant emissions (CO2, aromatic compounds, CO, etc.) based on industrial emission data and therefore to obtain a rigorous life cycle inventory. Different technologies are assessed for a fixed heating demand and hot water production of a typical French house: district heating fueled by wood chips, individual stoves or boilers fueled by wood logs or pellets. Electricity, natural gas, and fuel oil solutions complete the scenario set. The different heating solutions are compared in terms of their greenhouse gas emissions and of the cost of the final energy (including investment and operating costs). The important effect of minor pollutants (such as CO and volatile organic compounds) on the global warming potential of wood-to-heat chains is highlighted. The performance of wood scenarios compared to fossil-based ones is also highly dependent on the impact factor assumed for the biogenic CO2. The wood-based scenarios present a wide range of costs with pellet solutions being more expensive on investment and pellet production.

The aim of this work is to extract hemicelluloses polymers from spruce sawdust using High Voltage Electrical Discharges (HVED) pretreatment. HVED pretreatment was carried out in order to improve deconstruction of the wood matrix and to allow easier release of high molecular mass hemicelluloses. The results revealed the advantage of HVED activation step in the process of extraction. The yield of hemicellulose extraction increased with HVED treatment time. In fact, after 4 ms of HVED treatment time in 1M NaOH solution, the yield obtained was higher as compared to the untreated sample (19 mg/g of dry matter and 15.8 mg/g of dry matter respectively). The molecular weights of extracted hemicelluloses are very high (55 kDa and 47 kDa for 4 ms of HVED-treatment in 1M NaOH solution and water respectively). The use of different mediums of extraction with HVED pretreatment have revealed a selective solubilization of spruce hemicelluloses.

Barley for malting is evaluated by different grain quality measures, one of these measures is specific weight. An increased specific weight is assumed to lead to higher malt output, however this has not yet been proven. Specific weight is a measure of bulk density, a combination of both individual grain density and the packing efficiency of the grain. Links between specific weight or its components to aspects which may affect malt output have not been investigated. Here we examined correlations between barley grain density and nitrogen content, carbon content, starch content, amylose/amylopectin ratio and starch granule metrics. We show that nitrogen content and the proportional volume, number and surface area of starch B-granules positively correlated with grain density. An equation was built to predict grain density from grain nitrogen and the proportional volume of starch B-granules; this described 47\% of observed variation in grain density. An independent validation of the equation indicated that nitrogen content alone was sufficient to successfully estimate grain density. As nitrogen content is consistently positively correlated with grain density and hence specific weight, a high specific weight could be unfavourable for some malting end-uses which require low grain nitrogen. Achievement of high specific weight must therefore carefully consider end-user requirements.

For the first time, it was experimented with high voltage electrostatic field (HVEF) for the optimization of the bonding process of urea formaldehyde (UF) resin to wood. Varying HVEF treatment times (0-8min) and intensities (5-20kV) were applied. Wood surface characteristics, polymerization extent of UF, and bonding interphase of UF to wood were examined by electron spin resonance (ESR) spectroscopy, dynamic contact angle goniometers, Fourier transform infrared spectroscopy (FTIR), X-ray densitometer, fluorescence microscope and bonding strength measurement. The results indicated that HVEF treatments applied to wood veneer induced a decrease in contact angles and an increase in the free radicals of wood, and surface energy varied with treatment times and intensities. These varieties were because triggered free electrons, broken chemical bonds and new ions appeared on the wood surface with HVEF treatment. An aggregated performance was obviously obtained in micrographs and vertical density profiles (VPDs). It was explained that resin penetration into wood structure was significantly shallow, and resin concentration and density at bonding interphase were more enhanced than the control. This is due to the increment of surface energy and lower contact angles providing more chances for possible reactions of wood surface with the UF resin. Resin penetration depth and density varied with different treatment times and intensities. Increased cross-linking extent of UF was obtained under varied conditions of HVEF treatment. The bonding strength was measured as a function of treatment times and intensities respectively; it increased by 85\% and the wood failure ratio significantly increased by 70\% under HVEF treatment (20kV, 8min) due to the aggregation performance and more cross-linked UF resin. It was manifested that both treatment time and intensity play a significant role in HVEF treatment, and HVEF treatment has a significant influence on the characteristics of the wood surface and the bonding properties of wood composites.

Several solutions based on phase change materials (PCM) are used for the thermal regulation of buildings. In this study, a combination of the inertial effect of PCM and intra-ventilation regulation is proposed. The purpose is to increase the thermal inertia of the building envelope leading to a fast passive and active cooling of the indoor environment. The principle of the solution is the use of a polymer-stabilized paraffin in external walls integrating ventilation pipes. For that, an experimental study of a hollow concrete block with PCM and ventilation tubes is conducted to test its thermal response. Gathered to this part, a 3D numerical model is developed under COMSOL Multiphysics (R). The obtained simulation results are in good agreement with the experimental data. A parametric study is then performed including its actual characteristics against several conditions; it is revealed that the use of PCM gathered to the ventilation tubes enhances the thermal phase shift. It is stated that the forced ventilation through the tubes makes it possible to manage the energy and contribute to the renewal of the air.

Three different types of lignin (kraft, organosolv and phosphoric acid lignin) were characterized and tested as precursors of electrospun nanofibers. Polyethylene oxide (PEO) was added as a plasticizer and dimethyl formamide (DMF) employed as a solvent. It was found that the molecular weight of lignin was the key parameter to understand the differences of the mechanical stability of the resultant fiber mats. In the case of kraft lignin (KL), the influence of some changes in the synthetic process was also tested: applied voltage, pretreatment in air or not, and the addition of a small amount of Ketjen black. After pyrolysis in nitrogen flow, the obtained carbon nanofibers (CNFs) were characterized by different techniques to analyze their differences in morphology and surface chemistry. Vanadium electrochemistry in 3M sulfuric acid was used to evaluate the different CNFs. All fibers allowed electrochemical reactions, but we observed that the oxidation of V(II) to V(III) was very sensitive to the nature of the raw material. Materials prepared from kraft and phosphorus lignin showed the best performances. Nevertheless, when 1 wt.\% of Ketjen black was added to KL during the electrospinning, the electrochemical performance of the sample was significantly improved and all targeted reactions for an all-vanadium redox flow battery were observed. Therefore, in this work, we demonstrated that CNFs obtained by the electrospinning of lignin can be employed as electrodes for vanadium electrochemistry, and their properties can be tuned to improve their electrochemical properties.

Numerical study for the effect of an external magnetic field on the mixed convection of Al2O3-water Newtonian nanofluid in a right-angle vented trapezoidal cavity was performed using the finite volume method. The non-homogeneous Buongiorno model is applied for numerical description of the dynamic phenomena inside the cavity. The nanofluid, with low temperature and high concentration, enters the cavity through the upper open border, and is evacuated through opening placed at the right end of the bottom wall. The cavity is heated from the inclined wall, while the remainder walls are adiabatic and impermeable to both the base fluid and nanoparticles. After validation of the model, the analysis was carried out for a wide range of Hartmann number (0 \<= Ha \<= 100) and nanoparticles volume fraction (0 \<= phi(0) \<= 0.06). The flow behavior as well as the temperature and nanoparticles distribution shows a particular sensitivity to the variations of both the Hartmann number and the nanofluid concentration. The domination of conduction mechanism at high Hartmann numbers reflects the significant effect of Brownian diffusion which tends to uniform the distribution of nanoparticles in the domain. The average Nusselt number which increases with the nanoparticles addition, depends strongly on the Hartmann number. Finally, a correlation predicting the average Nusselt number within such geometry as a function of the considered parameters is proposed.

This study presented the behavior of a laboratory scale solar dryer, which was designed with the objective of meeting the needs of low income carpenters of the tropical region of Africa. The following materials were used to build the solar dryer: aluminum sheets painted in black, a wooden support, and a plastic polyethylene used as a cover. Drying was carried out in the city of Yaounde in Cameroon, and the tested boards were ebony (Diospyros crassiflora). Drying must be performed with the following conditions: slow process at a low temperature in order to maintain the proper air relative humidity. Since, no apparatus was used to force the circulation of the air, natural convection was the mode used by the dryer. The solar dryer was mathematically modeled by applying heat and mass transfer balance to the different components of the solar dryer. It is important to mention that the used heat and mass coefficients were proposed as variable with the operating conditions. The mathematical model was a reasonable description of the physical phenomena taking place in the dryer. The results show that the average relative error between numerical and experimental moisture contents was equal to 2.102\%. Heat transfer convective coefficients and global mass transfer coefficients varied with drying time from 0.25 to 5.5 W/(m(2)K) and from 1 x 10(-8) to 5.5 x 10(-8) m/s, respectively. The proposed model allowed designing and dimensioning the solar dryer, to the industrial scale. It allowed following the evolution of the different temperatures and moisture content of the tested material and then optimizing the design of the dryer and the drying process conditions. Based on the model, proposing the opening of the drying chamber during the night time and the use of substances capable of retaining heat in the chamber were some proposed solutions in order to have more efficient drying process. The modeling results showed also that an improvement can be obtained at the addition of a solar collector.

The bio-based materials have experienced in recent years a relevant evolution in construction and for many building applications. Despite the efforts to develop new solutions to achieve the objectives of numerical characterizations a few researches in this area have been carried out using a heterogeneous wood-cement composite. This study is based on a constructive approach using the finite volume method in order to generate a numerical model capable of reproducing;the equivalent transfer properties of a wood-cement composite. The challenge is to understand, design, and control this multiphase inhornogeneous structure and predict transfers and flows within the community in order to achieve an optimal functionality. Experimental measurements and microscopic characterization using X-ray microtomography were performed to compare and demonstrate the method validation. The comparative results demonstrate a less than 100\% deviation between the measurements and the simulations of the equivalent thermal properties. Thus, thermal conductivity and permeability, under different medium configurations, were characterized. Therefore, it was observed that these properties depend strongly on the porosity and the pore distribution in the continuous phase. Moreover, these two parameters are highly dependent on cement percentages in the structure.

The xyloglucans of monocotyledons are known to vary in the abundance of fucosylated side chains, with most commelinid monocotyledons having xyloglucans with lower proportions than non-commelinid monocotyledons. In many commelinid species, and some non-commelinid species that have lower proportions of fucosylated side chains, these side chains have been shown to be cell-type specific. To determine whether it is just the fucosylated side chains that are cell-type specific, or whether xyloglucan is cell-type specific in these species, we used the monoclonal antibody LM15 in conjunction with immmunofluorescence microscopy. We examined the distribution of cell-wall labelling among cell types in these species. The primary walls of all cell types were shown to contain xyloglucans in all species that had cell-type specific distributions of fucosylated side chains. This indicates that it is the fucosylated side chains of xyloglucans that is cell-type specific. Although the functional significance of xyloglucan fucosylation remains unknown, such cell-type specificity supports hypotheses that the fucosylated side chains may indeed have a functional role within the cell wall.

Biofuels and chemicals can be produced from lignocellulosic feedstocks using biotechnological processes. The effective utilization of carbohydrates from biomass for the production of biofuels necessitates the development of pretreatment technologies to enhance their enzymatic digestibility. Among all the various pretreatment methods currently studied and developed, the organosolv processes, in which organic solvents or aqueous organic solvent mixtures are used as the pretreatment medium, appear to be specially promising in the context of the biorefinery because (1) they produce cellulosic pulp with a good enzymatic digestibility for monomeric glucose production and (2) they allow a clean fractionation of the major biomass components (cellulose, lignin, and hemicelluloses) into three process streams. In this chapter we give an updated overview of organosolv methods using conventional solvents and ionic liquids which have recently gained considerable interest as solvents for lignocellulosic biomass and pretreatment.

It is not yet known whether differences in adhesion quality among genotypes are determined by changes in caryopsis cuticle permeability. We examined changes in candidate cementing layer biosynthetic and regulatory genes to investigate the genetic mechanisms behind husk adhesion quality. We used both commercially relevant UK malting cultivars and older European lines to ensure phenotypic diversity in adhesion quality. An ethylene responsive transcription factor (NUD) is required for the development of the cementing layer. To examine correlations between gene expression, cementing layer permeability and husk adhesion quality we also treated cultivars with ethephon (2-chloroethylphosphonic acid) which breaks down to ethylene, and silver thiosulphate which inhibits ethylene reception, and measured caryopsis cuticle permeability. Differential adhesion qualifies among genotypes are not determined by NUD expression during development of the cementing material alone, but could result from differences in biosynthetic gene expression during cementing layer development in response to longer-term NUD expression patterns. Altered caryopsis cuticle permeability does result in altered adhesion quality, but the correlation is not consistently positive or negative. Cuticle permeability is therefore not the mechanism that determines husk adhesion quality, but is likely a consequence of the required cuticular compositional changes that determine adhesion.

Lignin was extracted from coconut husk via alkaline pulping, either Kraft or soda. The isolated lignin samples were classified as hydroxy-benzaldehyde, vanillin, and syringaldehyde type according to Fourier-transform Infrared Spectroscopy, H-1 and C-13 Nuclear Magnetic Resonance (NMR) spectra. Soda lignin (SL) showed higher thermal stability and glass transition temperature (T-g) than Kraft lignin (KL) as proven by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), respectively. The soda-lignin-phenol-glyoxal (SLPG) resins with the optimum percentage of lignin substitution at 30\% showed improved solid content and gel time in comparison to 30\% of Kraft-lignin-phenol-glyoxal (KLPG) and phenol-glyoxal (PG) resin. The good mechanical properties in SLPG is due to the higher amount of molecular weight as well as higher phenolic and G-type unit in lignin that improve the properties of 30\% SLPG adhesive. Moreover, the addition of layered double hydroxides (LDH) as reinforced filler up to 15\%-30\% SLPG adhesive blend shows a great performance (especially mechanical properties) as compared to 30\% SLPG adhesive alone.

To enhance the bonding performance of bamboo, the high voltage electrostatic field (HVEF) treatment was used for flattened moso bamboo (Phyllostachys pubescens). Three bonding types including bamboo skin-bamboo skin (BS-BS), bamboo skin-bamboo pith (BS-BP) and bamboo pith-bamboo pith (BP-BP) were tested. Surface characteristics of HVEF-treated bamboo composites were analyzed by the electron spin resonance (ESR), X-ray photoelectron spectra (XPS), Fourier transform infrared spectroscopy (FTIR), fluorescence microscopy and vertical density profile (VDP). Mechanical properties, including bonding strength, modulus of rupture (MOR), modulus of elasticity (MOE) and boiling peeling rate of treated-bamboo composites were tested as well. The results of ESR, XPS and FTIR showed that significantly increased free radicals, broken chemical bonds and oxygen-containing groups (-OH, C=O and C-O) were obtained. These variations were attributed to the fact that triggered electrons were able to break oxygen and water molecules in the atmosphere under HVEF treatment and more broken chemical bonds (oxygen atoms and ions) appeared and reacted with bamboo surface. Higher change ratios involved in BS compared with BP were due to higher components of cellulose and lignin. HVEF treatment induced a significant decrease on adhesive penetration depth and an increment on density at bonding interphase. The highest decrease of adhesive penetration depth and increment of density at bamboo interphase were obtained in BS-BS while the least was BP-BP. All the bonding performance significantly enhanced after HVEF-treatment. The most robust and durable bonding performances were obtained in BS-BS type, and BP-BP showed the most increment extents of bamboo failure ratio. Results of this study revealed that: HVEF treatment was an effective approach for enhancing bonding properties of both bamboo skin and pith.

The present paper investigates numerically the effect of an external magnetic field on heat transfer and entropy generation of Ag-MgO (50:50vol\%)/water hybrid nanofluid flow in a partially heated irregular ventilated cavity. A finite-volume FORTRAN code has been written to solve the governing partial differential equations. New empirical correlations specifically dedicated to predict the dynamic viscosity and the thermal conductivity of the considered hybrid nanofluid were employed. After validation of model, the analysis has been done for a wide range of Reynolds number (10?Re?600), Hartmann number (0?Ha?80) and total nanoparticle volume fraction (0?phi?0.02). The results are presented in terms of streamlines, isotherms and isentropic lines as well as the average Nusselt number (Nu(m)), the average entropy generation (S-gen,(m)) and the Bejan number (Be-avg). The criterion =S-gen,(m)/Nu(m) is adopted to discuss the thermal performances of the system. The results reveal that the intensification of the magnetic field tends to attenuate the heat transfer convection and to reduce the thickness of the thermal boundary layer, close to the active walls. Globally, adding nanoparticles to the base fluid improves the heat transfer but increases the total entropy generation.

Specific weight influences the market value of barley grain, and in malting barley a high specific weight is thought to result in an increased malt output. However, links between specific weight and malt output have not yet been established. We hypothesised that packing efficiency and grain density will each contribute to specific weight. These traits would have implications for the malting process, highlighting the need for understanding what grain traits contribute to specific weight, before we can predict its effect on malting performance and efficiency. RESULTS We report that specific weight is a product of grain density and packing efficiency, in our study proportionally contributing 48.5\% and 36.5\% to variation in specific weight, respectively. We report that packing efficiency is determined by grain dimensions, and is negatively correlated with the sum of grain length and depth. Therefore shorter, thinner grains can result in an increased specific weight, which is likely to be detrimental for malting performance. We also demonstrate that among cultivars which have grains with contrasting size traits, the same specific weight can be achieved through differing grain densities. CONCLUSIONS Our results demonstrate that both grain dimensions and grain density must be considered jointly to optimise specific weight, and that the relationship between specific weight and malting performance and efficiency needs to be carefully considered with respect to how a high specific weight is achieved.

This study reports on the effects of unmodified autohydrolyzed ethanol organosolv lignin (AH EOL) and modified autohydrolyzed ethanol organosolv lignin on the structural characteristics and antioxidant properties upon incorporation of p-hydroxyacetophenone (AHP EOL). The lignin samples isolated from black liquor of oil palm fronds (OPF) were evaluated and compared using various complementary analyses; FTIR, H-1 and C-13 NMR spectroscopy, 2D-NMR spectroscopy (FIMBC and HSQC), CHN, GPC, HPLC and thermal analyses (TGA and DSC). Chemically modified organosolv lignin (AHP EOL) provided lignin with lower molecular weight (M-W), which has smaller fragments that leads to higher solubility rate in water in comparison to unmodified organosolv lignin, AH EOL (D-AHP EOL: 19.8\% \> D-AH EOL: 14.0\%). It was evident that the antioxidant properties of modified organosolv lignin has better reducing power in comparison to the unmodified organosolv lignin. Therefore, the functionalization of lignin polymers enhanced their antioxidant properties and structural features towards a various alternative approach in lignin-based applications.

Tannins are one of the most natural, non-toxic, and highly reactive aromatic biomolecules classified as polyphenols. The reactive phenolic compounds present in their chemical structure can be an alternative precursor for the preparation of several polymeric materials for applications in distinct industries: adhesives and coatings, leather tanning, wood protection, wine manufacture, animal feed industries, and recently also in the production of new porous materials (i.e., foams and gels). Among these new polymeric materials synthesized with tannins, organic and carbon gels have shown remarkable textural and physicochemical properties. Thus, this review presents and discusses the available studies on organic and carbon gels produced from tannin feedstock and how their properties are related to the different operating conditions, hence causing their cross-linking reaction mechanisms. Moreover, the steps during tannin gels preparation, such as the gelation and curing processes (under normal or hydrothermal conditions), solvent extraction, and gel drying approaches (i.e., supercritical, subcritical, and freeze-drying) as well as the methods available for their carbonization (i.e., pyrolysis and activation) are presented and discussed. Findings from organic and carbon tannin gels features demonstrate that their physicochemical and textural properties can vary greatly depending on the synthesis parameters, drying conditions, and carbonization methods. Research is still ongoing on the improvement of tannin gels synthesis and properties, but the review evaluates the application of these highly porous materials in multidisciplinary areas of science and engineering, including thermal insulation, contaminant sorption in drinking water and wastewater, and electrochemistry. Finally, the substitution of phenolic materials (i.e., phenol and resorcinol) by tannin in the production of gels could be beneficial to both the bioeconomy and the environment due to its low-cost, bio-based, non-toxic, and non-carcinogenic characteristics.

In the context of improving energy efficiency and thermal comfort in the building, the use of phase change materials (PCMs) is one of the suggested solutions. The proposed integration solutions concern the building envelope as well as the applications related to its operation. The study of the incorporation of PCM in the walls of the building was the subject of numerous works. However, the antisymmetric character of storing/recovering energy management in the walls is less controlled and do not fit the optimal conditions. In this study, a solution based on the direct integration of a stabilized PCM (gel) in an envelope including ventilation channels, was proposed to overcome this problem of antisymmetry storing/recovering and fitting with different fixed ambient conditions. The final aim is to develop the optimization strategy of a wall combining the heavy inertia offered by the PCM, intra-ventilation control and the contribution to air renewal energy demand.

In this context, an experimental study of a concrete block system is conducted to test the thermal response of this configuration by the application of cyclic solicitations. The comprehension of this integrated constructive solution essentially passes by the possession of validated numerical tools. For this, two models have been developed. The first model using the electrical-thermal analogy, based on an RC equivalence, is distinguished by its relative simplicity and weak time computing demand. Each of these two factors, R and C summarise the system properties and has a direct influence on the building transient simulations over a year. The second one is based on direct numerical simulation DNS of the energy and fluid flow equations using commercial code COMSOL Multiphysics. Such DNS is time consuming and could not be used to simulate over a year but aims only to validate the first RC circuit approach. A comparison of these two models with the idealised experimental data was carried out and allowed the validation of the thermal behaviour of the solution based on the integration of the PCM with core ventilation.

Good quality husk-caryopsis adhesion is essential for malting barley, but that quality is influenced by caryopsis surface lipid composition. Raman spectroscopy was applied to lipid extracts from barley caryopses of cultivars with differential adhesion qualities. Principal component regression indicated that Raman spectroscopy can distinguish among cultivars with good and poor quality adhesion due to differences in compounds associated with adhesion quality.

During biomass fractionation, any native acetylation of lignin and heteropolysaccharide may affect the process and the resulting lignin structure. In this study, Typha capensis (TC) and its lignin isolated by milling (MWL), ionosolv (ILL) and organosolv (EOL) methods were investigated for acetyl group content using FT-Raman, H-1 NMR, 2D-NMR, back-titration, and Zemplen transesterification analytical methods. The study revealed that TC is a highly acetylated grass; extractive free TC (TCextr) and TC MWL exhibited similar values of acetyl content: 6 wt \% and 8 wt \% by Zemplen transesterification, respectively, and 11 wt \% by back-titration. In contrast, lignin extracted from organosolv and [EMIm][OAc] pulping lost 80\% of the original acetyl groups. With a high acetyl content in the natural state, TC could be an interesting raw material in biorefinery in which acetic acid could become an important by-product.

Wood-fall ecosystems host chemosynthetic bacteria that use hydrogen sulfide as an electron donor. The production of hydrogen sulfide from decaying wood in the deep-sea has long been suspected to rely on the activity of wood-boring bivalves, Xylophaga spp. However, recent mesocosm experiments have shown hydrogen sulfide production in the absence of wood borers. Here, we combined in situ chemical measurements, amplicon sequencing and metagenomics to test whether the presence of Xylophaga spp.-affected hydrogen sulfide production and wood microbial community assemblages. During a short-term experiment conducted in a deep-sea canyon, we found that wood-fall microbial communities could produce hydrogen sulfide in the absence of Xylophaga spp. The presence of wood borers had a strong impact on the microbial community composition on the wood surface but not in the wood centre, where communities were observed to be homogeneous among different samples. When wood borers were excluded, the wood centre community did not have the genetic potential to degrade cellulose or hemicellulose but could use shorter carbohydrates such as sucrose. We conclude that wood centre communities produce fermentation products that can be used by the sulfate-reducing bacteria detected near the wood surface. We thus demonstrate that microorganisms alone could establish the chemical basis essential for the recruitment of chemolithotrophic organisms in deep-sea wood falls.

To construct calcium carbonate skeletons of sophisticated architecture, scleractinian corals secrete an extra cellular skeletal organic matrix (SOM) from aboral ectodermal cells. The SOM, which is composed of proteins, saccharides, and lipids, performs functions critical for skeleton formation. Even though polysaccharides constitute the major component of the SOM, its contribution to coral skeleton formation is poorly understood. To this end, we analyzed the SOM of the massive colonial coral, Porites australiensis, the skeleton of which has drawn great research interest because it records environmental conditions throughout the life of the colony. The coral skeleton was extensively cleaned, decalcified with acetic acid, and organic fractions were separated based on solubility. These fractions were analyzed using various techniques, including SDS-PAGE, FT-IR, in vitro crystallization, CHNS analysis, chromatography analysis of monosaccharide and enzyme-linked lectin assay (ELLA). We confirmed the acidic nature of SOM and the presence of sulphate, which is thought to initiate CaCO3 crystallization. In order to analyze glycan structures, we performed ELLA on the soluble SOM for the first time and found that it exhibits strong specificity to Datura stramonium lectin (DSL). Furthermore, using biotinylated DSL with anti-biotin antibody conjugated to nanogold, in situ localization of DSL-binding polysaccharides in the P. australiensis skeleton was performed. Signals were distributed on the surfaces of fiber-like crystals of the skeleton, suggesting that polysaccharides may modulate crystal shape. Our study emphasizes the importance of sugar moieties in biomineralization of scleractinian corals.

We investigate the mechanical and thermal properties of a composite structure manufactured from polypropylene matrix reinforced with marine waste fibers. Posidonia oceanica. We show that this fiber largely available on Mediterranean coasts presents many advantages compared to other natural fibers conventionally used as reinforcement. In fact, Posidonia fiber is extracted easily with only mechanical action. Moreover, it enhances the mechanical properties of the whole composite without any need of compatibilizers due to its hydrophobicity. Finally, apart from the mechanical performances, we demonstrate that the incorporation of the fiber with high ratio does not degrade its thermal properties which are a specificity of thermally resistant fibers that could open a wide range of applications.

This work focuses on a horizontally ventilated cavity filled with air, heated on one side wall and cooled on the floor surface. Therefore, this study has been carried out for a convective loop induced for a fixed Rayleigh number Ra= 10(6) and horizontal ventilation (moderate Reynolds number Re= 100) where the injection is either in cooperating or opposing to the convective loop. The study undertaken concerns different opening position in order to analyze the energy efficiency of such ventilation and the corresponding indoor air quality. The results obtained indicate that the natural convection and the forced flow (ventilation) play an important role in the flow structure and the mixing ability, the heat exchange (cooling need) and the temperature comfort. The optimum ventilating position is a compromise in order to minimize the cooling demand, keep the mixing ability and reduce the temperature heterogeneity.

Biochar is a potential medium for carbon storage, so its production and storage have been considered as is a crucial route to effectively achieve negative CO2 emissions. Meanwhile, torrefaction is a thermochemical conversion process for producing biochar. Biochar is featured by its hydrophobicity, which makes it different from its parent biomass with hygroscopicity and is conducive to material storage. To evaluate the hygroscopic transformation of biomass from torrefaction, two woody biomass materials of poplar (hardwood) and fir (softwood) are torrefied at temperatures of 200-230 degrees C, and the variations of color, equilibrium moisture content, and contact angle of raw and torrefied samples are examined. The results indicate that the total color difference of torrefied woods increases linearly with increasing mass loss. The hygroscopicity reduction extent in torrefied fir is higher than in torrefied poplar, and can be increased by up to 57.39\% at 230 degrees C. The tests of the contact angle suggest that the hygroscopicity of the raw woods is evidently exhibited, whereas the angles of the torrefied woods are in the range of 94-113, showing their hydrophobic surfaces (\> 90 degrees). The decarbonization, dehydrogenation, and deoxygenation phenomena of the biomass during torrefaction are also analyzed. It is found that the three indexes can be correlated well by the total color difference and hygroscopicity reduction extent. A comprehensive study on the improvement of hydrophobicity of produced biochar has been performed, which clearly shows the potential of carbon storage and negative CO2 emissions by biochar.

The fire retardance properties of rigid, biosourced phenolic foams derived from tannins, which are novel, environment-friendly thermal insulators, are essential before the latter can be applied to the building sector. In this work, tannin-based foams prepared from new formulations and using different foaming methods were investigated by thermo-gravimetric analysis (TGA), cone calorimetry, and pyrolysis combustion flow calorimeter (PCFC). It was found that the flammability strongly depends on the formulation, so that tannin foams perform very differently depending on the presence of surfactant and plasticiser and, more importantly, on their initial water content. Moreover, a good correlation was observed between TGA and PCFC results. Nevertheless, due to their highly resistant phenolic, crosslinked, polymer network, all materials released a quite low amount of hydrocarbon fuel during thermal decomposition, leading to low heat release rates and high ignition times, and thus providing very good fire retardance properties. Based on the above, the foam presenting the highest fire retardance was identified, confirming our conclusions about the role of the ingredients in the formulation.

The natural durability of five Cameroonians wood samples was evaluated using the European standard EN 350-1 with a slight modification. The capacity of extracts to inhibit the fungal growth was evaluated at different concentrations with propiconazole (a commercial fungicide for wood) as standard. Scanning Electron Microscopy (SEM) of wood blocks was carried out before and after extraction in different solvents. Unextracted and extracted wood blocks were exposed to fungal attack, with beech as a reference wood. Results showed that mass losses of non-extracted samples ranged from 0.1 to 59\% and those of extracted samples from 3\% to 40\%. Before extraction, all wood samples under study were classified as very resistant to fungi attack (class 1) with respect to the standard. After extraction, some of the wood samples became vulnerable to fungal attack. Movingui, padouk, and tali became less resistant to fungi attack (class 3). The SEM of wood revealed that the extractives were removed from the fibres. The effect of extractives on fungal growth showed that extracts weakly inhibited fungal growth up to concentrations of 250 mu g/mL but extracts of tali and movingui totally inhibited fungal growth at a concentration of 500 mu g/mL.

This new mechanical method of expansion allows obtaining a solid porous material after curing and hardening at room temperature, through a liquid foam formed by a tannin resin and an aqueous solution of surfactant. The stability of the as-obtained liquid foam and the influence of the amount of catalyst are reported.

A small-scale fire test was performed on a wood-cement panel intended as a permanent formwork. The tested panel was subjected on one side to a uniform heat flux of about 6 kW/m(2). Measurements of the temperature profiles were recorded with thermocouples embedded in the sample. The density and its variation with temperature were obtained by taking weight measurements. The thermal conductivity of the wood-cement composite at room temperature was determined using the hot plate method. Its variation with temperature and that of the specific heat were determined using analytical and numerical approaches. Using the obtained data, a pyrolysis model, implemented in Abaqus, was developed to simulate the effect of heat in the panel. The validation of the model is carried out by simulating charring tests. The model provided reasonable predictions for the thickness of the charred layer and the temperatures profiles across the depth of the panel. The model can supplement the testing of small laboratory samples to characterise the fire performance of these panels, and hence help establish their certification for use in sustainable construction.

With an average initial moisture content ranging between 0.4 and 0.48 kg/kg, the average final water contents are ranged from 0.15 to 0.18 kg/kg after 21 days in Yaounde during the months of November and December 2004. Modeling was applied from November 1st to the November 30th, to Sapele wood with 50 mm thick and 0.4 kg/kg initial moisture content dried in Bangui, Brazzaville, Douala, Kinshasa, Libreville and Yaounde until the final moisture content, which can vary from 0.13 to 0.1 kg/kg. Solar energy per cubic meter of wood was ranging from 2 to 4.3 GJ/m(3) with a maximal thermal efficiency between 12 and 47\%. Ndjamena\&$\#$39;s climate is not good to use solar drying because of its low air absolute humidity that gives a fast drop in the moisture content and consequently destroys the wood board quality. Bangui, Brazzaville, Douala, Kinshasa, Libreville and Yaounde give satisfactory alternative drying conditions using the studied solar dryer. However, it is important to use a solar collector in those six towns in order to reduce the effect of the air absolute humidity and improve the drying kinetic.

Nonlinear numerical models for the engineering design of mechanical connections in anisotropic materials require nonlinear material behavior of their components, which are essentially determined by material or structural testing. Herein, a multi-step approach for the parameterization of the nonlinear and anisotropic connection slip behavior is presented and applied to the ductile embedment behavior of steel dowels in wood. For this purpose, previously proposed regression functions for the slip behavior are reviewed, and further possible equations are discussed. Their suitability in the description of typical shapes of slip curves observed in connection testing is assessed before certain combinations are applied to an experimental dataset of embedment tests of steel dowels embedded in Laminated Veneer Lumber. The dependence of the regression parameters on the displacement range in the experimental dataset and the benefit of using parameters with a physical interpretation, for being able to exploit connection test data reported in literature, is highlighted.

The reaction of a desulphurized kraft lignin with hexamethylene diamine and dimethyl carbonate has allowed the development of isocyanate-free polyurethane resins. The present research work is based on previous studies made with hydrolyzable and condensed tannins, but takes advantage of the higher number of hydroxyl groups present in lignin and their different aliphatic and aromatic character. The obtained materials were analyzed by Fourier transform infrared (FTIR) spectroscopy, matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry and solid-state cross-polarization/magic angle spinning (CP MAS) C-13 nuclear magnetic resonance (NMR), which have revealed the presence of urethane functions. The interpretation of the results has shown a larger number of species than when tannins were used and has indicated the presence of two types of bonds in the new molecules formed: ionic and covalent bonds.

In the context of a biorefinery, the potential of the short rotation coppice \"poplar with bark\" as a feedstock for the acid-catalyzed ethanol-water Organosolv process and furthermore for possible applications of the biomass components was investigated aiming at optimal separation of the non-standardized woody biomass. The study was supported and evaluated by an experimental design (Box-Behnken). The statistical analysis showed an increase in lignin yield with rising process intensity with an optimum for precipitated lignin yield of 42\%. A change in downstream processing from lignin precipitation by simple dilution of the reaction water to stripping of the ethanol provided a 10\% higher lignin yield. Molecular weight distribution of the lignin samples as well as the number of aliphatic OH-groups within the lignin molecules decreased with intensified conditions whereas the phenolic group content increased. The cellulose content in the fibre fraction is hardly influenced by the pulping conditions, lignin and hemicellulose removal lead to a raising cellulose recovery.

Lignocellulosic materials can significantly contribute to the development of eco-friendly wood adhesives. In this work, glyoxal-phenolic resins for plywood were prepared using organosolv lignin, which was isolated from black liquor recovered from organosolv pulping of oil palm fronds (OPF) and considered to be an alternative to phenol. Glyoxal, which is a dialdehyde obtained from several natural resources, was used as substitute for formaldehyde. The structure of organosolv lignin and the resins were characterized by FTIR and NMR, and for thermal stability by TGA and DSC. The resins were further studied for their viscosity, pH, solids content and gel times. The resins performance as wood adhesive was further established from mechanical test in terms of tensile strength and modulus of elasticity (MOE) to obtain the optimum ratios of organosolv lignin, which replaces phenol in organosolv lignin phenol glyoxal (OLPG) resins. The adhesive composition having 50\% (w/w) of phenol substituted by organosolv lignin, termed as 50\% OLPG showed highest adhesive strength compared to phenol formaldehyde (PF) commercial adhesive.

A new formulation of quebracho tannin-based resin has been used to prepare bio-based rigid foams. The proposed foams were blown by using the simultaneous combination of two expansion methods by mechanical expansion as used for fire-fighting foams and by chemical expansion based on the release of water and other gases during the exothermal self-condensation of furfuryl alcohol. The combination of both methods allowed us to overcome certain limitations found in the preparation of foams exclusively based on mechanical expansion These were the resulting density (16\% lower than that obtained by mechanical expansion) and the mechanical properties (compressive strength improved of about 11\%). Resin chemorheology was characterized under stressed conditions using frequency and time sweeps as well as temperature ramps. The evolution of the linear viscoelastic functions during the reaction clearly showed the transition from viscous to strong gel-like behavior. The foaming and hardening processes were followed by the use of FOAMAT equipment and the resulting foams were characterized in terms of density (0.059-0.063 g/cm(3)), mechanical properties (compressive strength of 0.090-0.144 MPa) and thermal conductivity (0.046-0.048 W m(-1) K-1).

Numerical simulation of reinforced concrete structures requires the explicit representation of both the concrete and the reinforcement bars, where the two materials are modelled separately using appropriate constitutive laws including damage variables for concrete in compression and tension. Even if this way of modelling is convenient and satisfactory, it requires a huge computational effort especially in the case of large scale applications. The aim of this paper is to develop an alternative model dedicated for the simulation of large scale reinforced concrete structures with no need to represent explicitly the steel reinforcements. Based on the literature review, the authors developed a fictitious stress-strain relationship for reinforced concrete under tension. The model is based on the shape of the slip-adhesion curve between steel and concrete proposed by the European Committee for Concrete (C.E.B.) to estimate the crack opening widths. Relationships covering the cracked stage up to the yield point of the steel are proposed depending on the material properties of concrete and steel, on the reinforcement ratio, as well as on the crack widths. The developed model was successfully implemented in the ABAQUS commercial software. The effectiveness and computational efficiency are demonstrated through some examples under tensile and bending loadings.

The use of natural ventilation by large openings to maintain thermal comfort conditions in the premises is a concept that is perfectly integrated into the traditional architecture of countries in the Mediterranean region or in tropical climates. In a temperate climate where the architecture is not usually designed to respond to the use of natural ventilation is seasonal and is done at the initiative of the occupants by making changes in the design of their doors. The European interest in natural ventilation, as a passive building air- conditioning technology, is increasing and has been the subject of a research program commissioned by the European Community. In this work, the authors consider a part of a housing compound as a refreshing floor. This floor is maintained at a constant cold temperature, the one vertical wall at hot temperature and other surfaces are adiabatic. Various scenarios are considered for this work. Mixed convection for different boundary conditions and different configurations is carried out. In addition, an airflow is injected through a window and extracted on the opposite window. Classical conclusion and transitional value on Richardson number have been completed by the new thermal configuration with nonsymmetric thermal conditions. The complex 3D flow structure is more obvious when one of the two flows (ventilation or natural convection) dominates. However, the induced heat transfer is less sensitive to the added ventilation. In this study, the authors consider a part of a housing compound as a refreshing floor. This floor is maintained at a constant cold temperature, the one vertical wall at hot temperature and other surfaces are adiabatic.

Fine hemp fibers (cottonized hemp) were processed using steam explosion. The quantification of the defibration rate was performed by image processing. Based on this method, the hemp defibration was optimized using a response surface methodology based on three-variable central composite design for the production of elementary fibers with low variability. Optimal parameters for the steam processes were as follows: time=4.1min; temperature=191?. Biomass was impregnated with a solution of NaOH (8\%) before treatment, leading to a defibration rate of 91.2\%, which is producing approximate to 50\% fibers with length \<3mm, in good agreement with the experimental data. Damaged fibers originating from the conjugated effect of steam explosion and alkali hydrolysis were also observed.

The urban heat island phenomenon is generally defined as an air temperature difference between a city center and the non-urbanized rural areas nearby. However, this description does not encompass the intra-urban temperature differences that exist between neighborhoods in a city. This study investigates the air temperature dynamics of neighborhoods for meteorological conditions that lead to important urban heat island amplitude. Local climate zones (LCZs) have been determined in Nancy, France, and mobile screen-height air temperature measurements are performed using an instrumented vehicle. Initially, hourly measurements are performed within four different LCZs. These results show that air temperature within LCZ demonstrates a nocturnal cooling in two phases, i.e., a first phase between 1 to 3 h before sunset and 3 to 5 h after sunset, and a second phase from 3 to 5 h after sunset to sunrise. During phase 1, neighborhoods exhibit different cooling rate values and air temperature gaps develop between districts, while during phase 2, cooling rates tend to be analogous. Then, a larger meteorological data set is used to investigate these two phases for a selection of 13 LCZs. Normalized cooling rates are calculated between daytime measures and nighttime measures in order to quantify the air temperature dynamics of the studied areas during phase 1. Considering this indicator, three groups are emerging:

Results indicate that the relative position of LCZ within the conurbation does not drive air temperature dynamics during phase 1. In addition, measures performed during phase 2 tend to illustrate that cooling rates are similar to all LCZ during this period.

The reaction of condensation and cross-linking of desulfurized kraft lignin with triethyl phosphate (TEP) was explored. Catechol, a simple model of the aromatic ring of lignin, and glycerol, a model compound of the aliphatic hydroyl groups of the side chain of lignin, were employed under similar reaction conditions. Solid state cross-polarisation/magic-angle spinning (CP-MAS) C-13 NMR and matrix assisted laser desorption ionization time-of-flight (MALDI-TOF) spectroscopy studies showed that polycondensation occurs on phenolic hydroxyl groups of lignin, as well as on aliphatic hydroxyls groups of its side chain. The reactions appear to be favoured by higher temperatures and in the presence of ammonia. Preliminary adhesion tests on wood shown good hydrophobicity properties of the surface treated with lignin-TEP-based resin. Initial application tests carried out at high temperature demonstrated as good performance as metallic coating.

The aim of this work was to evaluate the chemical composition of some plantation wood and the assessment of their compatibility with plaster. A quantitative analysis of the chemical composition each of the species (Eucalyptus saligna, Cupressus lusitanica and Eucalyptus paniculata) was carried out, followed by chemical compatibility evaluation using different types of wood particles. The quantitative analyses were carried out on wood powder of size between 0.27 and 0.30 mm. The results obtained were 2.4, 3.4 and 1.6\% for ethanol-benzene extract (E-AB ); 2.6, 3.2 and 2.4\% for hot water extract (E-E); 12.4, 21.6 and 12.1\% for 1\% sodium hydroxide extract (E-s); 48.6, 48.4 and 40.4\% for cellulose content (C); 34.8, 34.3 and 36.3\% for lignin content (L); then 0.1, 0.6, 0.3\% for ash content (C-E) respectively of E. saligna, C. lusitanica and E. paniculata. Chemical compatibility C-A was measured from hydration temperature curves as a function of time using the area method. The results showed that compatibility C-A decreased from 100 to 68\% as the wood content in the composite increased up to 15\% for all species and types of particles used. At this minimum value, the species was still considered as highly compatible in accordance with literature. Although compatibility is good, it decreased in the order E. paniculata followed by E. saligna and then C. lusitanica, the least compatible due to the inhibiting action of extractives.

Natural convection, in a shallow horizontal cavity filled with a nanofluid, is studied. The flow is driven by Lid driven convection (LDC). External applied constant heat fluxes on the bottom wall of the cavity is applied, whereas the vertical walls are subjected to variable heat fluxes. The nanofluid concentration is treated as heterogeneous mixtures with a weak solutal diffusivity. A modified formulation taking into account the physical properties (thermal conductivity, viscosity) versus on nanofluids type and concentration and the spatial heterogeneous concentration induced by the Soret effect is presented. The induced nanofluid heterogeneity can affect the heat transfer. The heat transfer increases with increase of the boundary motion. The analytical solution, based on parallel flow approximation, is found to be in good agreement with numerical solution. The existence of both natural and anti-natural flows is demonstrated. Indeed, the subcritical Rayleigh number for the onset of instability tends to disappear when the supercritical threshold is largely affected.

This article presents the results obtained an experiment carried out to measure the thermal impacts of green walls on buildings. The experiment deals with full monitoring of a green wall set up on a scaled down experimental mockup of buildings located in La Rochelle city. Results underline the positive effect of green walls in summer and show moderate reduction of heat losses in winter. The distinction made between measured heat gains and heat losses through the compared facades helps to apprehend the energy impact of the envelopes greening. Besides, we analyzed through experimental observations the dynamic behavior of the green wall system, and we highlighted the importance of such an experimental model to take into account the vertical hygrothermal effects. The primary objective is better understanding of the thermohydric behavior and the energy impact of green walls by direct comparison between data recorded simultaneously on different configurations of buildings and streets with and without use green walls. Measurements of temperature, humidity and heat fluxes through facades with and without greening provide valuable data to assess performances of this technique, to analyze the thermal effects, and finally this gives data for further numerical studies.

Wood offers important potential for biofuel or chemical production by fast pyrolysis but exhibits variable chemical composition that impacts pyrolysis product composition. Here, fast pyrolysis of heartwood, sapwood, and bark isolated from Douglas fir (softwood) and oak (hardwood) was studied by a microfluidized bed reactor (MFBR) combined with single photoionization mass spectrometry (SPI-MS) to provide insights into the wood zone effects on the composition of pyrolysis volatiles. The difference in pyrolysis volatile composition has been clearly unraveled by principle component analysis (PCA) based on the major ions detected by SPI-MS. Some specific product markers have been defined for each wood zone (heartwood, sapwood, and bark) and related to the chemical composition of wood samples (lignin, carbohydrates, and minerals). The catalytic effect of minerals (notably potassium) has a higher impact on carbohydrate decomposition than on lignin decomposition for a given wood type. Therefore, sapwood and heartwood (for both oak and Douglas fir) can be clearly discriminated by specific markers mainly from carbohydrate pyrolysis. Interestingly, our results show that the wood cylinders exhibit a more marked wood zone effect on product compositions compared to fine powders. SPI-MS results were further compared to those of, pyrolysis gas chromatography/mass spectrometry (Py-GC/MS), and many of them are consistent. MFBR combined with SPI-MS is a selective analytical technique to figure out the effect of wood composition on pyrolysis volatiles.

A smart shear connection system was tested in order to be used in manufactured elements of a lattice of wooden slats and a cross offset. This type of floor element can present advantages both in terms of weight and suitable insulating filler (Adalberth et al. 2001; Kawasaki and Kawai 2006; Kermani and Hairstans 2006; Dodoo et al. 2014). This connection is made to provide a substitute for a glue connection. The shear connection proposed is made by double-sided grooving timber interfaces to form a cross section. A specifically designed test assembly was constructed to measure and guarantee homogeneous contact pressure in interface test specimens. Shear test results are presented and compared in terms of capacity and stiffness with glue connections. The principal conclusions are as follows: the allowable shearing resistance of the grooved timber-timber joints can approximately reach the resistance of glued connections. The stiffness of the joints is improved by increasing the pre-stress applied for holding contact in the assembly. The grooved timber-to-timber joints exhibit non-linear behaviour which dominates the behaviour of the whole system. Therefore, the behaviour of a unit connection must be determined to obtain the mean load-carrying capacity and stiffness of a system with grooved connections.

The aim of this paper was to determine the moisture desorption isotherms and essentials thermodynamic properties of two Oak wood varieties. Desorption isotherms were measured using a static gravimetric method at 50, 60, 70 and 80 degrees C within the range of 5-90 \% relative humidity.

The isosteric heat of desorption and the differential entropy decreased with increasing moisture content according to an exponential law equation and varying from 2.03 to 31.14 kJ/mol and from 73.98 to 4.34 J/(mol K), respectively. The linear relationship between differential enthalpy and entropy satisfied the enthalpy-entropy compensation theory. The sign of Gibbs free energy was found to be positive (+283 J/mol) and (+97 J/mol) for Quercus robur and Quercus canariensis, respectively. The isokinetic temperature was found to be greater than the harmonic temperature. Based on the enthalpy-entropy compensation theory, it could be concluded that the moisture desorption isotherm of Oak wood is a non-spontaneous and enthalpy-controlled process.

The understanding of lignin softening and pyrolysis is important for developing lignocellulosic biorefinery in order to produce carbon fibers, polymers additives, green aromatics, or biofuels. Protobind lignin (produced by soda pulping of a wheat straw) was characterized by thermogravimetry, calorimetry (for glass transition temperature and heat of pyrolysis reactions), in situ H-1 NMR (for the analysis of the mobility of protons upon lignin thermal conversion), and solution-state C-13 and P-31 NMR (determination of functional groups in lignin). In situ rheology reveals the real-time viscoelastic behavior of lignin as a function of temperature. Upon heating, lignin undergoes softening, through glass transition overlapped with depolymerization, and is followed by the solidification of the softened material by cross-linking reactions. The lignin residues were quenched within the rheometer at the midpoint temperatures of softening and solidification regions and were further analyzed by elemental analysis, GPC-UV of acetylated THE soluble fractions, FTIR, solid C-13 NMR, and laser desorption ionization (LDI) combined with very high-resolution mass spectrometry (HRMS). We present the first report on lignin biochars analysis by LDI-HRMS. NMR and FTIR analyses provide the evolution of functional moieties in lignin residues. C-13 NMR, GPC-UV, and LDI FTICRMS analyses depict the depolymerization mechanism combined with cross-linking and demethoxylation reactions. An overall physical and chemical mechanism for the thermal conversion of alkali lignin is proposed based on these complementary analyses.

The present paper aims to predict the hygrothermal behavior of massive wood panel considered as bio-based building material. In this context, we developed a macroscopic model coupled no linear heat, air, and moisture transfers that incorporates simultaneously the effect of thermal diffusion and infiltration phenomenon on the building material. The model inputs parameters were evaluated experimentally according to the recognized standards of material\&$\#$39;s characterization. Therefore, numerous series of hygrothermal calculation were carried out on the 1-D and 2-D configuration in order to assess the dimensionless effect on such wooden material. Two types of boundary conditions were considered and examined. The first are at the material scale of wood drying process. The second type of conditions is at the wall scale, where the conditions of the building ambiance are considered. Moreover, the model sensitivity to the driving potentials coupling and to the parameters variability was considered and examined. It has been found that the coupling in the model had a remarkable impact on both kinetics of temperature and moisture content.

Optimal linear wood welding parameters along the end-grain-to-end-grain faces were determined for Eucalyptus saligna, Eucalyptus pilularis, and Corymbia maculata. Joints made using Eucalyptus saligna showed a significant interaction between welding time ( WT), amplitude ( WA), and pressure ( WP). A preheating phase of 3 s at 0.4 MPa WP and 0.75 mm WA coupled with a WT of 2 s at 2.0 MPa WP and 1.5 mm WA provided the best shear strength results of 5.1 MPa. Joints made using Eucalyptus pilularis and Corymbia maculata snapped once the holding pressure was removed, suggesting that end-grain-to-end-grain welded fibers cannot withstand the thermal stresses generated when the surface to be welded is too small ( e. g., 13.5 cm(2)). However, grain orientation had a significant effect on the weld mechanical properties, as very strong edge-grain-to-edge-grain joints were produced with Eucalyptus pilularis and Corymbia maculata ( 9.5 and 6.2 MPa, respectively). The joints made of Eucalyptus saligna also showed significant improvement ( 7.3 MPa). Energy efficient combinations were usually those involving low WA and short WT, as WP had a marginal effect on energy consumption during the welding process.

In the context of reduction of CO2 emissions and costs in the construction industry, substitution of concrete by wood for foundation piles seems to be a promising alternative. To promote the use of local wood in pile foundation, diagnostic and prediction methodology of wood decay in soil need to be improved. Outdoor mesocosm decay experiments were performed to evaluate the potential use of beech wood as foundation piles. The stochastic occurrence of soil fungal inoculum in contact with mini-stakes and water gradient in wood explained the observed patchy wood decay pattern. Various patterns of wood rotting fungi were identified. The correlation between measured strength loss and mass loss was weak. Multivariate analyses using biochemical and physico-chemical data as inputs allowed section categorizations and prediction of wood strength. Accuracy of the prediction was validated by experimental measurement of the compression parallel to the grain (f(c),(o)).The categorization of unknown sections was computed by PLS-DA and provided clues inferring their service life. The described procedure has the potential to be transferred to on-site measurements to predict the f(c,o) of wood foundation pile or any potentially damaged timber structure.

The aim the present work was to produce carbon foams with as different as possible porous structures but with similar composition and carbon texture for studying precisely the influence of different structural parameters such as density, cell size or interconnectivity on the physical properties of these foams. Over 60 different cellular carbon foams were obtained by pyrolysis of phenolic-furanic rigid foams, whose structure was tailored through some changes in the formulations. The structures of all of these materials were thoroughly characterised through scanning electron microscopy (SEM) and X-Ray microtomography. Both methods proved to give very consistent results, justifying the use of the simpler one, i.e., SEM. Very broad ranges of bulk densities (0.015 \<= d \<= 0.333 g cm(-3)) and of average cell diameters (100 \<= D \<= 5000 mu m) were obtained. Despite these very different morphologies, elemental analysis, helium pycnometry and Raman spectroscopy studies showed that the carbon constituting the foams can be considered as identical. The results presented here should be used as a basis for the most thorough and extensive studies of physical properties of vitreous carbon foams.

Phytotechnologies are a set of sustainable, ecological options notably for alleviating pollutant linkages induced by contaminated soils. However, concerns exist regarding the processing of trace elements (TE)-enriched biomass and the fate of TEs in the end-products. The fractionation of phytoremediation TE-enriched non-woody lignocellulosic (tobacco) and woody (birch, willow) phytoremediation-borne biomasses was studied using ethanol organosolv, soda and dilute acid pretreatments. TE distribution in the process fractions (pulp, liquid effluents and lignin) was further examined. In dilute acid conditions, a wood pretreatment performed at 170 degrees C in the presence of 2\% w/w of sulfuric acid allowed an efficient extraction of the metals in the water effluent (approximate to 90\% for Mn and Zn) producing a clean pulp. A soda pretreatment resulted in a low metal extractability, especially at high temperature. At 170 degrees C or above with 15\% w/w of NaOH, metals were mostly recovered in the cellulosic pulp (70\%- 98\%). Using organosolv pulping, the TE contents were in the decreasing order: pulp \>\> water stream \> lignin. The TE organosolv extraction in the liquid phase varied depending on the TE metal and on the species but was generally low. Metal extractability increased with the water content in the solvent of the organosolv pulping but decreased with temperature. Enzymatic hydrolyses of TE-enriched and metal-free pulps were investigated and it was concluded that the TE concentrations had little or no effect on polysaccharide enzymatic hydrolysability by cellulases. The final destination of the various fractions for valorization in a biorefinery setting is discussed, regarding their TE content.

In this study, activated carbons were prepared from date palm rachis (RPK) and jujube stones (NJK), by-product agricultural wastes which have been tested for the elimination of reactive dye BEZAKTIV Red S-MAX (BRSM) from aqueous solutions by batch adsorption method. Both activated carbons were prepared using chemical activation by KOH as an impregnating agent (rate of KOH/biomass (w/w) of 0.74) at 800 degrees C in the presence of inert gas (N-2). RPK and NJK were characterized using BET, SEM, FTIR and Boehm titration mass. The results show that RPK possess the higher specific surface area (1160 m(2)/g). The effect of contact time, solution temperature and solution pH on the adsorption of BRSM dye were also studied. The experimental data were analysed using Langmuir, Freundlich and Temkin isotherm models. The equilibrium data fitted well with the Langmuir isotherm model, and the adsorption capacities were calculated to be 12821 and 28.49 mg/g using RPK and NJK, respectively. The kinetic data were fitted to pseudo-first order, pseudo-second order, elovich and intra-particle diffusion model. Thermodynamic parameters such as Delta G degrees, Delta H degrees and Delta S degrees were also estimated for the adsorption study and they were found to be spontaneous and endothermic processes. Desorption and regeneration study was made to test the viability of reusing the adsorbents. Lastly, it was found that RPK is efficient in dyes removal from real wastewater.

Green walls and green roofs are innovative construction technologies involving the use environmentally friendly materials. In addition to their aesthetical and environmental benefits, green walls have significant thermal effects on buildings and heat islands within high-density urban areas. In this paper, we study the impact of an innovative green wall system on building energy performance. These green walls have specific composition and particular geometry that can lead to higher thermal performances and therefore more significant impact on building energy performance. The development, validation and prior integration of a hygrothermal green wall model in a transient building simulation tool make possible the assessment of the energy performance of buildings when covered by green walls. The used model was adapted to be the particular forms and composition of the studied green walls. In parallel, this type of green walls has been installed on a one tenth building mockup to be experimented. The aim of the experiment is to measure the thermal effects and to calibrate some parameters of the numerical model. The results highlight the thermal benefits of this kind of green walls in summer condition. They reduce annual energy demand of building up to 37\% for hot climates.

Parameters characterizing wood and air were studied in order to analyze the performance of a wood solar dryer functioning under Moroccan climate. A mathematical model based on the climate data of Rabat city was used to investigate theoretically the wood drying process. Two wood speciesthuya (Tetraclinis articulate) and pine (Pinus pinaster)-were examined in the present study. The results obtained by computer simulations are in good agreement with the experimental values. Furthermore, our findings indicate that the use of a global mass transfer coefficient for low temperature convective and homogenous drying conditions allows the influence of the principal operating parameters (wood thickness, wood density, air temperature, air velocity and ventilation mode) on the drying time to be estimated with great accuracy. Analyses pertaining to the two studied wood species revealed that(1) pine dries more quickly than thuya, (2) the drying process is faster in the summer relative to other seasons, (3) increasing the air velocity by 100\% results in a 20\% reduction in the drying time, and (4) continued ventilation reduces the drying time by 43\%.

This research work showed that spruce wood can be butt welded in a short time end-grain to-end-grain without any treatment. Wood welding has already been shown to be well adapted to the manufacture of wood structures of larger dimensions. When pressure increased, the welded material formed is of higher density and consequently the water resistance improved. The welded spruce samples present a much improved water resistance when the welding pressure was increased from 2.75 MPa to 3.75 MPa for the same welding time of 6 s. The welded interphase in end-grain-to-end-grain butt welding of spruce appears to occur by the formation of an interphase having the appearance of finger-joints. This is due to the different behaviours of the late and early wood rings of spruce during welding. This, by increasing the surface of contact, is shown to improve the water resistance of the original butt joint.

Despite the importance of designing support structures for solar collectors, very little reliable work has been done to investigate the forces of the wind on heliostats of solar tower at real scale. Wind loads on heliostats are usually determined at low-speed wind tunnels scale, where the design full-scale Reynolds number cannot be reached. In the present study, measured data are used to validate the simulations at wind tunnel scale. Thereafter, by using the same method, three-dimensional numerical simulations of turbulent wind flow around a big heliostat of solar tower are performed. The obtained numerical results are presented for several elevation angles at normal operation and stow position. The results revealed that the known stow position (when the backside of the heliostat is facing the ground) is not the optimum position (other optimum elevation angles are discovered) especially with high wind speed, and the effect of torque tube is significant on heliostat mean wind loads.

The inhibitive effect of ultrafiltrated oil palm fronds (OPF) lignins on the corrosion of mild steel in 0.5 M HCl solution has been investigated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PP) and weight loss measurement.

The results from this corrosion test clearly reveal that all ultrafiltrated lignins behaved as a mixed-type inhibitor with predominant anodic (organosolv lignin) or cathodic (alkaline lignin) effectiveness. It was deduced that the inhibition process was spontaneous and the inhibitors were mainly physically adsorbed onto the mild steel surface.

For this purpose, the pyrolysis of biomass was conducted in a fixed bed reactor allowing a good control of pyrolysis conditions. Miscanthus and the macromolecules extracted from this same biomass (holocellulose, cellulose, ethanol organosolv lignin) were pyrolysed to various final temperatures (200-500 degrees C).

Network formation, cure characteristics and bonding performance of tannin-based resins were investigated in order to establish structure-property relationships between the stage B and stage C. Tannin-aldehyde and base-catalyzed autocondensed tannin resins were synthesized and characterized for molecular weight distribution, cure kinetics and cure chemistry by means of GPC, DMA and C-13 CP/MAS NMR spectroscopy and solvent stability tests. The resins performance as wood adhesives was further established from lap-shear tests and microscopic observation of the bondline. Resins prepared with highly reactive aldehydes, such as formaldehyde or glyoxal, exhibited a significant extent of hetero-condensation reactions, fast cure kinetics, a high storage modulus and good solvent stability of the stage C-resin. In contrast, resins prepared with bulky aldehydes of low reactivity, such as citral, were dominated by autocondensation reactions, and exhibited slower cure kinetics, a lower storage modulus and solvent-stability of the stage C-resin, alike those neat autocondensed tannin resins. However, all resin systems fulfilled the standard requirements for wood adhesive bonding for interior applications. Additionally, storage modulus increase during cure was found to be a good predictor of the stiffness of the wood-bonded assembly, useful to discriminate between the autocondensation and heterocondensation cure chemistries.

Complementary analytical methods have been used to study the effect of potassium on the pyrolysis mechanisms of cellulose and lignocellulosic biomasses. Thermogravimetry, calorimetry, high-temperature H-1 NMR spectroscopy (in situ and real-time analysis of the fluid phase formed during pyrolysis), and water extraction of quenched char followed by size-exclusion chromatography coupled with mass spectrometry have been combined. Potassium impregnated in cellulose suppresses the formation of anhydrosugars, reduces the formation of mobile protons, and gives rise to a mainly exothermic signal. The evolution of mobile protons formed from K-impregnated cellulose has a very similar pattern to the evolution of the mass loss rate. This methodology has been also applied to analyze miscanthus, demineralized miscanthus, miscanthus re-impregnated with potassium after demineralization, raw oak, and Douglas fir. Hydrogen mobility and transfer are of high importance in the mechanisms of biomass pyrolysis.

Flax fiber is an industrially available, renewable product with attractive technical properties for the composite industry such as density, mechanical strength and sound/heat insulation. Applications are developing quickly for biocomposites based on these fibers. However, unlike plastics, there is no standard used to assess its degree of contamination by microorganisms. Thus, the aims of this work were to detect and quantify molds in samples of nonwoven fibrous materials from industry and high resin content natural matrix-natural fiber biocomposites. In a first attempt, we tried to evaluate the fungal development on the nonwoven materials as defined in the ISO 846 standard. Despite the materials having been inoculated with molds, no fungal mycelium could be detected by this way. To validate this observation, we developed a qualitative approach based on the specific aniline blue method to stain the mycelium present in the material. This allowed us to detect the mold occurrence in the material and to evaluate the colonization extent on the nonwoven fibrous materials incubated under different conditions. The biocide efficiency of a boric acid pretreatment of flax fibers used in the manufacturing process of nonwoven fibrous materials and high resin content natural matrix-natural fiber biocomposites was determined by grading the mold development using the microscope-based method that we developed. The results showed clearly that in optimal mold growth conditions, (Aw \> 0.6, 26 degrees C) the colonization of the material was hampered by the boric acid pretreatment of the flax fibers. To get semi-quantitative data of the colonization extent, we used a molecular method. DNA was extracted from the different materials and the ribosomal region of the fungal DNA was amplified by PCR allowing the detection and the quantification of fungal colonization in the biosourced material. Results confirmed the microscopy-based method. Work is currently in progress to determine risk classes of mold colonization in wood-derived and fibrous-based composite materials.

The characterization of fibers extracted from leaflet, the empty fruit bunches, leaf sheath, and spath of palm tree was performed. The fibers were extracted using three different procedures through chemical and / or enzymatic methods. The raw fibers studied have xylose contents between 13-22\% and glucose content between 30\% and 45\%. The microfibrillar angle (MFA) values are in the order: bunch \> spath \> leaf sheath \>\> leaflet. Spath and leaf sheath, which naturally occur in a woven form present poor mechanical strength but could be readily used to produce cheap composites. Leaflet fibers extracted from date palm tree exhibiting a low MFA (16 degrees), a high cellulose content, and cellulose crystallinity present the highest ultimate tensile strengths (approximate to 1250 N.mm(-2)).

The growing demand of bio-sourced products leads to an increasing interest for the development of new resources of raw materials. In order to generate a higher economic value in the oleoproteaginous sector, meals, co-products of oil extraction present qualities capable of being exploited in a wide range of sectors. These meals are mainly commercialized in feed application, but remain relatively weak used in the chemistry domain or even in food. To enlarge these applications, the pre-treatment of the raw material by grinding and air-classification offers technological outlooks for the conception of new extraction processes of interesting components. The present publication has the following goal: to examine the diversification of oleoproteaginous meal market, out of traditional usage in the chemistry domain; to characterize the meals chemical composition and their techno-functional properties; to evaluate the feasibility of valorizing these meals and their derivatives as substitutes or additives allowing the reduction of the level in petro-chemical product, for example, for the production of adhesive formulations for particle boards. To achieve this, different actions have been performed: evaluation of the potential and accessible market starting from metropolitan crops; analysis of the panorama of intellectual property for the identified markets; chemical characterization of ground plant meals and their soluble and insoluble fractions; applicability of the different obtained fractions, in terms of foaming power, emulsifier and gelifier; first application tests starting from rapeseed and sunflower meals in the wood panel board domain. The obtained results have allowed: to draw up a map of the inventive activity bound to the valorization of proteins from rapeseed, sunflower and soy meals and pea flour in various applications, highlighting the dynamism and the growing interest for industrials and academics to use oleo-proteaginous plant proteins; to explore techno-functional properties brought by these plant meals and their derivatives, in particular in the wood panel domain.

New formaldehyde-free Quebracho tannin foams were developed for horticultural/hydroponics and floral applications. These foams included in their composition a wetting agent and at least one compound able to neutralize the residual acidity derived from acid catalyst. Their densities were between 0.048 and 0.066 g/cm(3) and compression strength, between 0.07 and 0.09 MPa. Scanning electron microscopy (SEM) images showed open porosity and average cell size of 125-250 mu m. Water absorption peaked at 98\% (vol) while residual pH value was 5. The new tannin foams do not result to be phytotoxic and are apt to the conservation of fresh cut flowers and as support matrices for horticulture and hydroponics. They have shown performances comparable or superior to commercial synthetic phenolic floral foam used as reference.

High levels of humidity in buildings lead to building pathologies. Moisture also has an impact on the indoor air quality and the hygrothermal comfort of the building\&$\#$39;s occupants. To better assess these pathologies, it is necessary to take into account the heat and moisture transfer between the building envelope and its indoor ambience. In this work, a new methodology was developed to predict the overall behavior of buildings, which combines two simulation tools: COMSOL Multiphysics (c) and TRNSYS. The first software is used for the modeling of heat, air and moisture transfer in multilayer porous walls (HAM model: Heat, Air and Moisture transfer), and the second is used to simulate the hygrothermal behavior of the building (BES model: Building Energy Simulation). The combined software applications dynamically solve the mass and energy conservation equations of the two physical models. The HAM-BES coupling efficiency was verified. In this paper, the use of a coupled (HAM-BES) co-simulation for the prediction of the hygrothermal behavior of building envelopes is discussed. Furthermore, the effect of the 2D HAM modeling on relative humidity variations within the building ambience is shown. The results confirm the importance of the HAM modeling in the envelope on the hygrothermal behavior and energy demand of buildings.

Tannin-furanic biobased foams, based on the co-reaction of bark-derived condensed tannins and thermoset furanic polymers, have low thermal conductivity, are self-extinguishing, and have high fire resistance, which allows their development for several industrial uses. One of their main drawbacks, however, is the absorption of water within the foam itself. Another problem is the rather friable surface, which is a definite drawback for some potential applications. In this work, these two problems are minimized or eliminated by introducing a component of oil-grafted tannin in the foam formulation. The incorporation of fatty chains markedly decreased foam friability and increased water repellency in the body of the foams. These properties and the compounds formed by fatty acids grafting onto the tannin flavonoids were extensively tested.

A large number of plants used in traditional medicines have been shown to possess antitumor activities. The aims of this study were to evaluate any anticancer effect of the essential oil (EO) extracted from P. tortuosus against B16F10 melanoma cancer cells in vitro as well as in vivo. In vitro, EO was shown to induce apoptosis and to inhibit migration and invasion processes. Further investigation revealed that EO decreased focal adhesion and invadopodia formation which was accompanied by a drastic downregulation of FAK, Src, ERK, p130Cas and paxillin. Moreover, EO treatment decreased the expression level of p190RhoGAP, and Grb2, which impair cell migration and actin assembly. Mice bearing the melanoma cells were used to confirm any in vivo effectiveness of the EO as an anti-tumor promoting agent. In mice dosed with 100 mg EO/kg/d (for 27 days), tumor weight was inhibited by 98\% compared to that in mice that did not receive the product. In conclusion, these data suggested to us that an EO of P. tortuosus could evolve to be a potential medicinal resource for use in the treatment of cancers.

Slow pyrolysis of different biomasses (miscanthus, douglas fir and oak) was conducted in a U-shape fixed bed reactor combined to (1) on-line analysis of the vapors (primary tar) by soft photoionisation mass spectrometry (single photoionisation time-of-flight mass spectrometer, SPI-TOFMS), (2) quantitative off-line analysis of condensed vapors by GC*GC/MS-FID and (3) permanent gas analysis. The U-shape fixed bed reactor allows controlling external mass transfers, temperature of the bed, quenching char at targeted temperatures and quantifying mass balances. The mass yields in solid, condensable products and gas are studied between 200 degrees C and 500 degrees C. The soft on-line photoionisation analysis leads to a more interpretable mass spectra with few fragment ions and gives the evolution of the main markers of volatiles produced in real-time as a function of the temperature. The chemical structure of the markers analyzed on-line by SPI-TOFMS is assigned by GC*GC/FID-MS analysis. The mechanisms of hemicelluloses, cellulose and lignin pyrolysis in the complex network of biomass (including minerals catalytic effect) are discussed.

A hygrothermal model of green walls and a model of mass flows in street canyons have been proposed and implemented in a building simulation program (TRNSYS). The coupled models allow the study of the hygrothermal interaction of green walls at the interface of the detailed building model and the urban microclimate of the street. Its use highlights the effects on both urban microclimate and buildings energy loads, especially in the summer period. While reducing anthropogenic heat release, green walls set up on west or east facades mitigate the street air temperature and reduce building cooling loads depending on streets\&$\#$39; aspect ratio. Some of the canyon model parameters were calibrated through numerical comparison with experimental data on a reduced scale mockup. This mockup has been designed specifically to assess the green walls hygrothermal impact and to evaluate the developed numerical tools. This experimental calibration made simulating the green walls interactions with street canyons of different aspect ratios possible. The experimental and numerical results obtained with green facades underline the advantage of this modeling approach for the design of passive cooling for buildings and mitigation of excessive thermal conditions within street canyons in dense cities in warm climates.

We have developed a model on drying of two tropical woods of ayous (Triplochiton Scleroxylon) and frake (Terminalia Superba) coming from Cameroon forests. Some thermophysical parameters used in the model were experimentally obtained in this work while the remaining properties were from literature. A comparison is doing between numerical results of our model, these given by the Luikov\&$\#$39;s model and experimental data. Numerical simulation results from the developed model give close agreement with experimental results. We note that Luikov\&$\#$39;s model not gives a satisfaction results in the non-hygroscopic domain in the case of frake. The present model can be used to explain the drying phenomenon of these two tropical species and can be applied to others species when necessary thermophysical parameters of these species are known. In a future work, it is important to integrate the influence of anatomical direction on our numerical and experimental results.

Continuous observation was performed using confocal laser scanning microscopy to visualize the three-dimensional microscopic growth of the brown-rot fungus, Postia placenta, for seventeen days. The morphological characterization of Postia placenta was quantitatively determined, including the tip extension rate, branch angle and branching length, (hyphal length between two adjacent branch sites). A voxel method has been developed to measure the growth of the biomass. Additionally, the tip extension rate distribution, the branch angle distribution and the branching length distribution, which quantified the hyphal growth characteristics, were evaluated. Statistical analysis revealed that the extension rate of tips was randomly distributed in space. The branch angle distribution did not change with the development of the colony, however, the branching length distribution did vary with the development of the colony. The experimental data will be incorporated into a lattice-based model simulating the growth of Postia placenta.

Parametric optimization using dynamic simulation of a solar thermal system for producing hot water, space heating and cooling was developed. The system layouts include a single-effect absorption chiller activated by heat generated by flat plate solar collectors and stored in a solar storage tank. Two construction types were compared; the first is the typical construction in Algeria (low thermal mass with U-values of 1.25 W/m(2)K, single glazing), which represents the majority in the country, while the second is a High-Energy-Performance building (with U-values of 0.35 W/m(2)K, double glazing), representing the pilot project called ECO-BAT. Three of Algeria\&$\#$39;s regions were considered to evaluate the climatic effect of solar systems integration. Algiers represents the coastal region; Djelfa, the highlands region; Tamanrasset, the Sahara region. In parametric study, two solar collectors\&$\#$39; field parameters were analysed, including the surface area and the tilt angle. The results indicated that building loads are significantly reduced (12\%, 44\% and 22\% for Algiers, Djelfa and Tamanrasset, respectively). The solar energy contribution is more than 60\% for all cases, a significant contribution for an efficient building. In all cases, we observed that the solar fraction reaches more than 45\% when the optimum parameters of the solar system are selected.

The present study sheds light on the physical and chemical characteristics of microcrystalline cellulose (MCC) isolated from oil palm fronds (OPF) pulps. It was found that the OPF MCC was identified as cellulose II polymorph, with higher crystallinity index than OPF alpha-cellulose (CrIOPFMCC: 71\%\> CrIOPF alpha-cellulose 47\%). This indicates that the acid hydrolysis allows the production of cellulose that is highly crystalline. BET surface area of OPF MCC was found to be higher than OPF alpha-cellulose (S-BETOPFMCC: 5.64 m(2) g(-1) \> SBETOPF alpha-cellulose :Q(a)(0) 2.04 m(2) g(-1)), which corroborates their potential as an adsorbent. In batch adsorption studies, it was observed that the experimental data fit well with Langmuir adsorption isotherm in comparison to Freundlich isotherm.

The effects of growing stage (immature and mature) and home cooking methods (boiling and steam cooking) on the phytochemical contents, and antioxidant capacity of faba bean were investigated. Different faba bean morphological fractions (whole pod, pod coat, whole seed, seed coat and cotyledon) were analyzed. The antioxidant capacity was evaluated by the DPPH radical scavenging capacity, total antioxidant capacity, and oxygen uptake inhibition. The results showed that the immature faba bean fractions had significantly higher phytochemical contents and displayed a better antioxidant activity than those of mature ones; the highest level of phytochemicals and the strongest antioxidant activity were recorded in the seed coat. This study demonstrates also that cooking caused significant decrease in the phytochemical bioactive contents, and antioxidant activity, depending on the morphological fraction and cooking practice. The results of this study revealed also that steam cooking would be preferred to preserve the bioactive phytochemicals of faba bean.

Sorption behavior of four tropical woods coming from Cameroon is studied using a Dynamic Vapor Sorption-Intrinsic apparatus. Sorption isotherms at 20 degrees C and 40 degrees C of Triplochiton scleroxylon (obeche), Entandrophragma cylindricum (sapele), Sterculia rhinopetala (lotofa) and Terminalia superba (frake also called limba) are compared to those in the literature with methods using saturated salts for lotofa and frake with satisfactory results. Experimental values are fitted using two sorption isotherm models. Sorption hysteresis is greatest in sapele and least in frake. When temperature increases, differences in the hysteresis of sorption among the woods decreases. Hystereses of all studied woods ranged from 0,5 to 3\%. Our studied woods have lower equilibrium moisture content probably caused by the higher values of extractives content. The water sorbed molecules on multilayer during both adsorption and desorption at 20 degrees C and 40 degrees C is greater in the case of frake and lower in the case of lotofa. The water sorbed molecules on multilayer of sapele is greater than those of obeche. The predominance of multilayer over monolayer of our woods is from 0,2 to 0,4 relative humidity in adsorption phase, and from 0,3 to 0,4 relative humidity in desorption phase.

Context Woodcutting is a very old technology but scientific research is scarce on the subject. In the last 50 years, much work on basic mechanisms as well as on industrial processes has been done in France.

Aims The specific nature of wood introduces strong differences between wood and metal cutting processes. The paper focuses on French teams\&$\#$39; contributions.

Results The basic aspects of the tool-material interaction for different basic modes in woodcutting are highlighted. In primary conversion such as sawing, veneer cutting or green wood chipping, huge progress comes from automation and the possibility of linking the process to log and product quality through new sensors. In secondary processing, much has been done on the links between the cutting process, surface qualification and the properties of these surfaces for further processing, such as gluing or coating. Tool wear depends on the cutting process, timber quality and species. Trade-offs are required in tool technology and coating technologies may improve tool life.

Conclusion A large amount of knowledge and innovation has come from 50 years of worldwide research effort, with France being particularly active in this period. The transfer of skills from metals cutting industry was often a key, but much is needed to move closer to both metal cutting sector and woodcutting skills among craftsmen.

In this paper, a newly developed heat and moisture transfer model for green envelopes is integrated in a transient building simulation program (TRNSYS) in order to investigate its dynamic performances coupled with a multizone building code. On the one hand we focus on the understanding of the coupled heat and mass transfers between green envelopes and the building; and on the other hand we study the model accuracy to assess the vegetation impacts together with building design. At first, the model reliability is verified through experimental comparisons during a summer period. Then, the developed simulation tool is used to assess the impacts of green walls on building energy performance. Since this model involves different hygrothermal transfer phenomena, the detailed numerical model results are analyzed to determine the weight of each phenomenon: evapotranspiration, shading effect and additional thermal resistance of green roof or wall. The results highlight the thermal benefits in summer and winter, especially for the west walls. The analysis of the different transfer mechanisms show that the foliage shading reduces the surface temperature variation whereas the evapotranspiration ensures the passive cooling when the water availability is sufficient.

The coupling of matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) mass spectrometry with C-13 nuclear magnetic resonance (NMR) is a suitable method for examining the composition of hydrolysable tannins and has been applied to the investigation of valonia oak (Quercus aegylops) acorn tannin extract.

Traces of catechin gallate were also observed in this tannin extract. The tannin from acorns of valonia oak was used to substitute up to 50\% of the phenol used in the preparation of phenolic resins as adhesives for wood particleboard. These phenol-tannin-formaldehyde resins showed comparable performance to phenol-formaldehyde resins.

Natural convection, in a shallow horizontal cavity filled with two layers immiscible fluids, is studied both numeric and analytic. The horizontal walls of the enclosure are heated by the bottom and cooled by the upper by a uniform heat fluxes while the verticals one are subject to heat fluxes of variable intensity. The analytical solution, based on the parallel flow approximation, is found to be in good agreement with a numerical solution. The existence of both natural and antinatural flows is demonstrated. Indeed, the critical Rayleigh number for the onset of motion is dependent on the side heating intensity. In the case where the upper fluid is more viscous than the bottom one, multiple solutions are possible as well as the a steady states in a range of ratio of the viscosity of the fluids. The fact that one of the two fluids is more heat conductive, affect not only heat transfer generated but also the intensity of flows and the existence of the third cell where we found several solutions. The present model yields explicitly the flow patterns and Nusselt numbers in terms of the governing parameters of the problem.

CH4 decomposition over a wood char was investigated as an alternative green catalyst.to produce hydrogen from hydrocarbons. Pyrolytic carbon (pyrocarbon) deposition leads to apparent deactivation of the catalyst by pore-mouth plugging. The activity of the carbon bed and its available surface area are easily restored by H2O gasification. The used char with pyrocarbon deposition was even found to be more reactive to gasification than the fresh char used in our conditions. This finding was highlighted by: (i) determination of gasification reaction extents by steam, (ii) temperature-programmed oxidation (TPO) of the fresh, used and reactivated chars and (iii) TPO under differential scanning calorimetry of these chars and demineralised chars. High-resolution transmission electron microscope (HRTEM) analysis of the chars showed different multiscale organisation of the carbon materials (disordered and graphitic mesoporous nanostructures). The fast regeneration of the used char could be attributed to the catalytic effect of the minerals present in the char that are reduced under our conditions of CH4 conversion. The predominant oxidation of the pyrocarbon compared to the char during its regeneration is evidenced through differential annealing (at 1800 degrees C) followed by XRD analysis. The oxidation of pyrocarbon is faster than the oxidation of the weakly reactive mesoporous carbon in char as shown by the HRTEM analysis. Consequently, wood char is an effective, easy to regenerate and cheap catalyst for converting hydrocarbons (CH4 or tar) into syngas.

The aim of this work was to identify and quantify the chemical and structural modifications occurring during the pyrolysis of Miscanthus x giganteus. Miscanthus was pyrolyzed at slow heating rate (5 K/min) in the temperature range 200-400 degrees C. The biochars were then characterized by combining diffuse reflectance infrared Fourier transform spectrometry (DRIFTs) and Ultraviolet Raman spectrometry (UV Raman). In addition, the quantification of the functional groups remained on the biochars was conducted by temperature programmed desorption-mass spectrometer (TPD-MS) analysis.

DRIFT analysis showed that the decrease in the hydroxyl and C-H stretching bands and the evolution of the carboxyl vibration peak mainly occur between 300 and 350 degrees C. The evolution of the main markers (H2O, CO, CO2, CH4, and H-2) of the functional groups presents in the biochars as analyzed by TPD-MS is consistent with the spectroscopic analysis. It shows two peaks. The first one in the temperature range of 200-380 degrees C was explained by the loss of the main O- and H- containing groups and to the main primary volatile compounds.

The phenolic composition of sumac root barks was studied. Colorimetric assays, FT-IR and NMR were used to examine the phenolic composition and tannins nature. Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry was used to examine the structure of the tannin oligomers. TGA analysis was used to study the thermal stability of sumac tannin extract. Analyzes showed that sumac root barks are rich in condensed tannins, especially procyanidin and prodelphinidin types. Flavonoid oligomers of dimers, trimers, tetramers, pentamers and hexamers kind were detected in MALDI-TOF-positive ion mode analysis. TGA analysis showed thermal stability of sumac tannins compared to other condensed tannin types and pomegranate hydrolyzable tannins.

This paper deals with the experimental investigation of transient behavior and thermal storage capability of a sensible heat storage unit. The former is designed to store solar energy by using sand as a storage medium. A cubic unit has been designed employing three configurations of embedded charging tubes to study the performances of the system. The storage material used in this experimentation (sand) has been characterized by its, grain size, density, and heat capacity. Performances of the thermal storage bed (including charging time, energy stored rate, charging energy efficiency) have been evaluated for selecting the storage material. From our experiments, we found that the number of charging tubes affects significantly the storage performances.

Condensed tannins have been successfully used as substitutes for phenol in the production of resins for wood products. However, the enhancement of the properties of tannin-based resins with nontoxic and cost effective additives is of great interest.

In the present work, the performance enhancement of tannin-based particleboards with cellulose nanofibers was investigated.

In presence of 2 \% of cellulose nanofibers, the viscosity of tannin-based adhesives and the internal bonding strength (IB) of the corresponding particleboards were increased from 350 to 5,462 mPa center dot s and from 0.85 to 0.98 MPa respectively. The modulus of elastic (MOE) and modulus of rupture (MOR) of the resins were also notably increased while thickness swelling (TS) of the panels was not affected.

The addition of cellulose nanofibers to tannin adhesives is an effective method for the production of high performance particleboards. Tannin-based adhesive containing 2 \% of cellulose nanofibers exhibits the best mechanical strength.

Formaldehyde-free quebracho tannin foams were prepared for the first time. Several simple formulations have been presented in order to study the capital influence of each component on foaming and therefore on the characteristics of the obtained foams. Incorporation of a non-ionic surfactant leads to smaller cells and a more homogeneous cell size distribution. Cross-linking agents improve the mechanical properties of foams. A combination of different catalysts allows control of the ratio between the expansion/hardening processes. The understanding of the roles and interactions of the different components of formulation make possible the design of tannin foams having specific properties.

Solid state NMR methods are required to analyze biomass as a function of its chemical or biological treatment for biofuels, chemicals, or biochar production. The native polymers network in lignocellulosic biomass and other solid materials, such as coal, coke, or biochar, can hardly be analyzed by liquid state NMR due to their poor swelling ability without chemical modification. A H-1-C-13 two-dimensional heteronuclear correlation (HETCOR) experiment with frequency-switched Lee-Goldburg (FSLG) irradiation is performed on a high field spectrometer (750 MHz). This method leads to previously unattained resolution for biomass and biochar and offers a unique ability to reveal their chemical composition. The formation of aromatic moieties from carbohydrates and lignin thermal conversion is clearly distinguished. This method can be applied to all other carbonaceous materials.

Nitrogen-doped carbon materials (NCMs) were obtained by amination of tannin by hydrothermal carbonisation (HTC). NCMs presented different morphologies depending on the amination method: (i) powders by HTC of tannin in a concentrated aqueous ammonia solution; (ii) gels without using any crosslinker by HTC in distilled water of tannin first dissolved in concentrated ammonia and then evaporated. Whatever the method, (i) or (ii), HTC was carried out at different temperatures: 180, 190, 200, 210 or 220 degrees C, with further pyrolysis at 900 degrees C under nitrogen. The morphology and chemical composition of the resultant materials were discussed. We compared our results with those reported in the open literature and we concluded that HTC of tannin in a concentrated aqueous ammonia solution allowed obtaining outstanding materials because they have both surface areas, higher than 500 m(2) g(-1), and high N content, around 8 wt.\%.

Many studies have been performed to assess potential utility of natural products as immunomodulants to enhance antitumor activity in situ. In this study, an essential oil (EO) from the aerial parts of Pituranthos tortuosus was prepared using hydrodistillation, its composition was characterized, and its immunomodulatory potential was assessed. The results indicated that the EO contained sabinene, a-pinene, limonene, and terpinen-4-ol as major constituents. EO was also found to be able to significantly promote lipopolysaccharide (LPS)-stimulated splenocyte proliferation, suggestive of a potential for activation of B cells and enhanced humoral immune responses in hosts given this product. Effects of EO on cell proliferation and apoptosis were also investigated in B16F10 melanoma cells. EO-induced tumor cell growth inhibition was associated with characteristic apoptotic changes in the cells, including nuclear condensation. In conclusion, these data suggested to us that an EO of P. tortuosus could evolve to be a potential medicinal resource for use in the treatment of cancers.

This article describes that the modification of lignin by incorporation of aromatic scavengers (2-naphthol: AHN EOL and 1,8-dihydroxyanthraquinone: AHD EOL) during delignification process has improved the physical properties of the lignin fractions. Smaller fragments of lignin with high phenolic -OH content, increased solubility and antioxidant activity have led to improved inhibitive property of the modified lignin. The inhibition efficiency (84-93\%) of both modified lignin (500 ppm) were observed to be better than unmodified organosolv lignin (EOL). It was deduced that the inhibition process was spontaneous and the inhibitors were mainly physically adsorbed onto the mild steel surface.

Timber strength grading has become a major issue in the European Union during the last years, due to the introduction of the Eurocode 5 and all its related standards. Currently, the most performing strength grading machines are able to locally detect the boards\&$\#$39; knots sizes and positions and interpret this information through adapted grading models. The best lead to improve their accuracy seems to be the introduction of new information about the boards and adapt the mechanical model to take them in account. Small grain angle causes high reduction of clear wood\&$\#$39;s mechanical properties; local value of slope of grain appears to be of high interest. The aim of this study is to quantify the additional accuracy that grain angle information can bring to an optical scanner used as a strength grading machine. A specific grading model has been developed accordingly, and the results obtained for different machine/model/loading combinations are presented. These results show that slope of grain measurement can significantly improve the accuracy of the optical scanner, for both modulus of elasticity and modulus of rupture estimations.

In combustion and gasification reactors, solid fuels such as coal or biomass undergo a pyrolysis step to form volatiles and a char. Pyrolysis is combined with an oxidation by O-2, H2O and/or CO2 of the resultant char. Here we propose an original approach to model the oxidation of a single char particle. The intrinsic chemical reactivity of the char surface is assessed by the reactive surface area (RSA). The evolution of the RSA upon the conversion of the particle (burn-off) is modelled by a specific kinetic law similar to the law used to model the evolution of active sites in catalysis. This approach is applied on experimental results taken from the literature for coal and wood chars for O-2, H2O or CO2 gasification. The evolution of the total surface area (TSA) is modelled by the random pore model. Diffusional limitations are also accounted for.

Tannins are non toxic, cheap and abundant polyphenolic oligomers extracted from tree barks. They can be easily used for preparing thermoset resins that are natural at the 70-95\% level, depending on the cases. From these resins, highly porous monoliths can be obtained by different techniques such as classical physical or chemical foaming, mixed physical/chemical foaming, by less-conventional methods such as emulsion-templating and stabilisation and hardening of either aerated emulsions or liquid foams. The resultant materials are not only interesting per se, but are also key precursors of novel cellular carbons having a broad range of applications. The present paper briefly reviews the latest advances for producing tannin-based cellular materials and their related characteristics and properties.

Physical properties such as mechanical performance, thermal conductivity, and porous structure were characterised to identify the large potential of applications of these new cellular foams, fully bio-based and probable easier biodegradability.

In this work, lignin polyols were prepared from the liquefaction of kraft lignin and from the direct liquefaction of Elaeis guineensis lignocellulosic waste. The liquefaction reaction was performed with polyhydric alcohols using sulfuric acid as catalyst at 160 degrees C. The physical and chemical characterizations of lignin and lignin polyols were conducted by elemental analysis, Fourier transform-infrared spectroscopy, H-1 and C-13 nuclear magnetic resonance (NMR) spectroscopy, molecular weight distribution, and thermogravimetric analysis (TGA). Quantitative C-13 NMR showed that all aliphatic hydroxyl group values of polyols noticeably increased with the use of the two methods compared to kraft lignin. The average molecular weight analysis of the liquefied product showed that it exhibited high molecular weight compared to kraft lignin. Both structural and thermal characteristics suggest that lignin polyols would be a good substitute for kraft lignin in the synthesis of polymeric compounds such as environmentally friendly resins or wood adhesives, as it presents higher amounts of activated free ring positions, higher molecular weight, and high thermal stability.

A good design of dowel type fastener connections is essential to ensure safe designs for the whole structure and cost effective solutions. With reinforced connections, engineers can achieve better capacity of the connection and safer designs by increasing the ductility of the connection (so-called \"capacity design\" with a ductile connection to be the weak point). This paper presents an overview of the reinforcement of dowel type connections. Most of the failures encountered in dowel type connections occur because of an excess of shear stresses or tensile stresses perpendicular to the grain in the connection area. Because of the large amount of situations and reinforcement techniques, this report mainly focuses on the reinforcement of dowel-type connections when the dowels are mainly loaded parallel to the grain. For such connections, modes of failure of un-reinforced and reinforced connections, updated design models and the effect of the reinforcement on the ductility of the connection will be presented. Among the various types of reinforcement techniques available, nowadays, self-tapping screws have found a wide field of application and they will be the main focus of this report.

This paper presents a new approach for understanding localized compressive behavior perpendicular to the grain based on beams subjected to three-point bending. It was intended to take into account the coupling between compressive stresses perpendicular to the grain due to support reactions and shear stresses. To validate this, model, results of compression tests have been examined. The digital image correlation (DIC) method has been applied in order to analyze the deformation fields in support areas. The tests allow confirming the presence of spreading effect in the vicinity of support areas according to the DIC method. An analytical formulation has therefore been proposed to quantify distribution versus increasing compressive strength perpendicular to the grain, including shear effects. A scale effect and support conditions have also been highlighted using three different geometries and two types of tests.

The purpose of our work is the development of a local agricultural waste biomass material, Ziziphus jujuba known as Nebka (NB), into activated carbons to remove humic acid (HA) from aqueous solutions. This was further treated with nitric acid solutions. The surface characteristics of the adsorbent were calculated using the standard Brunauer-Emmet-Teller method (BET). The microstructures of the samples were observed with scanning electron micrographs. Chemical characterization of the samples was carried out by selective titrations and Fourier Transform Infrared Spectroscopy (FT-IR). On the basis of the BET results, we have obtained the best microporous activated carbon oxidized (surface area of 970 m(2)/g, microporous volume of 0.170 cm(3)/g and total pore volume of 0326 cm(3)/g). Adsorption studies were conducted using a batch process, to study the effects of contact time, pH and temperature. The pH dependent sorption of HA was found maximum at pH range 4-6 for an initial concentration of 50 mg/L. The equilibrium adsorption data was analyzed using Langmuir and Freundlich isotherm models, and the kinetic data was analyzed using pseudo-first order and pseudo-second order kinetic models. The equilibrium data were well fitted to the Freundlich isotherm. The adsorption reached equilibrium after 300 mm and the maximum adsorption capacity was about 76.92 mg/g at 20 degrees C according to the Langmuir model. The adsorption kinetic was found to follow the pseudo-second-order kinetic model. Thermodynamic study showed that the adsorption of HA onto oxidized activated carbons was feasible, spontaneous and endothermic at 20-40 degrees C.

In the context of expansion of cities and raise of climate change awareness, urban planers are looking for methods and tools in order to take into account the urban heat island phenomenon. This study analyzes the way urban fabric modifies urban climate through the utilization of a climate scheme called Local Climate Zone (LCZ). This classification has been applied in Nancy (France). Urban indicators have been calculated so as to build 13 LCZ in the Great Nancy Area. The screen-height air temperature distribution has been investigated inside these LCZ via mobile measurements. Air temperature amplitude has mainly demonstrated lower values at nighttime than in daytime in urbanized LCZ types. Recurrent microscale hotspots and coldspots have been located in LCZ presenting heterogeneous urban fabric. Two Control Sites (CS) have been built in each LCZ. The CS average temperature has revealed good likeness with the spatially averaged air temperature. Average nocturnal air temperature differences between pairs of LCZ types have been obtained. These differences vary from less than 1 degrees degrees C for close LCZ types to more than 4 degrees degrees C for dissimilar LCZ types.
