This paper deals with an original and non-biocidal chemical treatment consisting of a vacuum/pressure impregnation step of beech wood with a water-borne mixture made from heat-activated condensation of succinic anhydride (SA) and glycerol (G). Chemical structures of adducts were established using matrix-assisted laser desorption ionization time-of-flight mass spectroscopy (MALDI-TOF) investigations. Beech wood was impregnated and cured in order to induce in situ polymerization of glycerol/succinic adducts (GSA) in the cell walls, leading to the formation of polyglycerol succinate (PGS) polyester. Various treatment conditions were investigated depending on the duration (6-72 h) and curing temperature (103-160 degrees C). Weight percent gains (WPGs) ranging between 40 and 60\% were obtained. Attenuated total reflectance-middle infrared spectroscopy (ATR-MIR) and carbon-13 nuclear magnetic resonance (C-13-NMR) spectroscopy confirmed polyester formation. A curing temperature of 160 degrees C was found to be the best condition to totally avoid polymer leaching, and brought the anti-swelling efficiency (ASE) up to 64\%. Decay resistance of PGS-treated wood against Trametes versicolor and Coniophora puteana was also strongly temperature and time dependent: performances fit with the EN113 standard requirements if a curing temperature of 160 degrees C was applied.

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.

The aim of this study is to present a new hybrid solar-biomass dryer and carry out thermal analysis based on energy and exergo-sustainability analysis considering all the available exergy stream of solar radiation, air stream through the collector, and exergy of the moisture in the product. 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 effect on the entropy production and MHD convection of the hybrid nanofluid Al2O3-Cu/water (water with Cu and Al2O3 nanoparticles) in a porous square enclosure is studied numerically via Galerkin finite element method. The enclosure used for flow and natural convection analysis is subjected to sinusoidal varying temperatures at the boundaries. Calculations were performed for specific parameters of the Rayleigh number (Ra = 10(3)-10(6)), porosity ratio (epsilon = 0.1-0.9), Darcy number (Da = 10(-5)-10(-2)), Hartmann number (Ha = 0-100) and nanoparticles concentration (phi = 0-0.08). The numerical results are presented by velocity profiles, isotherms, streamlines, and Nusselt number. They indicate that the isotherms subject to estimation variations under Ha boost from 0 to 100 as Ra enhances. At high Ha, the conduction transfer mechanism is more obvious. Also, it is seen that the convective heat transfer becomes stronger with the enhancement of the Ra while it detracts with the rise in Ha. Due to the Ra increase, the flow cell becomes stronger. For Ra = 10(6) and higher Hartmann numbers, the isotherms remain constant which is an indication of convection predominance.

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 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.

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.

Potassium is a natural catalyst in biomass thermochemical conversion and plays an essential role in plant\&$\#$39;s growth. To figure out the catalytic effects of potassium on the thermochemical behaviors of biomass, the pyrolysis, combustion, and torrefaction characteristics of rubber wood are comprehensively studied using a thermogravimetric analyzer where the biomass is impregnated by potassium carbonate (K2CO3) at different concentrations. The impregnated potassium is clearly exhibited in the spectra of Fourier-transform infrared spectroscopy, while X-ray diffraction indicate that the cellulose crystallinity decreases with increasing the potassium concentration which increases the biomass reactivity in pyrolysis. The ignition temperature of the potassium-impregnated biomass is lowered slightly when compared with the raw biomass; alternatively, its burnout temperature is reduced profoundly, suggesting that the addition of potassium into the biomass can substantially intensify its oxidative reactivity. Considering the treated biomass torrefaction, its cellulose decomposition at 250 degrees C is intensified, rendering a reduction in the solid yield with increasing potassium concentration. With the same mass loss at 200-300 degrees C, at least 28\% of torrefaction time can be saved for the potassium-impregnated biomass. Accordingly, the catalytic effect of potassium on biomass thermochemical conversion is clearly outlined. Moreover, the produced potassium-rich biochar is conducive to the developments of carbon storage, soil amendment, and negative emissions technologies.

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.

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.

This study aims at appraising the capability of tannic powders of African locust been pod husks (Parkia Biglobosa) and of the India tamarind (Pithecellobium dulce) peel to bind Africa antiaris sawdust particles in order to manufacture environmental panels without formaldehyde emission.

The panels produced from the different powders have been characterized. The mechanical characteristics (MOE: modulus of elasticity and MOR: modulus of rupture) determined by the bending tests are found to respect the threshold specified by the ANSI A208.1 (Medium density fiberboard, National Particleboard Association, Gaithersburg, 2009) standard.

After demethylation, eucalyptus pyrolysis oil has higher reactivity with formaldehyde in alkaline media than the raw oil. The objective of the present work was to evaluate the effect of adding polymeric diphenylmethane diisocyanate (PMDI) on a demethylated oil-based adhesive. Chemical composition of pyrolysis oil was determined by gas chromatography/mass spectrometry. Before and after demethylation, the eucalyptus pyrolysis oil was analyzed by carbon-13 nuclear magnetic resonance spectroscopy (C-13 NMR) and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF). Demethylated oil-based adhesive was analyzed by MALDI-TOF. Plywood panels were produced with adhesives supplemented with 0, 4, 8, 16 and 20\% PMDI and an extra treatment applying a reference phenolic adhesive. The experiment encompassed six treatments with four replicates, totaling 24 panels. As demonstrated by nuclear magnetic resonance analysis, the demethylation reaction was effective in removing methyl groups from the methoxyls of syringol and derivatives, turning them, respectively, into pyrogallol and its derivatives. PMDI was effective as a cross-linking agent, enhancing the mechanical performance of the original demethylated-pyrolysis-oil adhesive. In dry condition and after boiling test, plywood manufactured with formulations adding 16 and 20\% PMDI had shear strengths statistically equal to panels bonded with the reference phenolic adhesive.

This paper presents an experimental investigation on a novel adhesive free engineered Wood Products (AFEWPs) as an alternative to the conventional glued EWPs which have a high degree of petrochemicals. The research outcomes demonstrate the feasibility of using compressed wood dowels (CWD) as a joint element, to connect timber laminates and members as well as to substitute for adhesives and metallic fasteners. The paper describes the production of thermo-mechanically compressed wood dowels as well as the manufacturing of the dowelled timber specimens. The strength and stiffness properties of CWD are characterized based on three-point bending tests and compared to the values obtained from uncompressed wood specimens. After that, the paper discusses the relative mechanical performances of three-layer dowelled oak beams subjected to four-point bending, in comparison to their conventional glued counterparts. Finally, the paper shows results obtained from double shear push-out tests under both monotonic and cyclic loadings, using two wood species, namely spruce and oak. The obtained results show clearly the potential of thermo-mechanically compressed wood dowel, as a joint fastener, for load bearing capacity.

The effect of extraction conditions on polyphenols contents and condensed tannins by microwave-assisted extraction (MAE) was studied for the first time to our knowledge. Moroccan barks of Acacia mollissima was used to extract phenolic compounds. The variables studied are the following: power extraction, time extraction and solvent nature. Five powers extraction were tested: 150 W, 250 W, 300 W, 450 W and 600 W. A significant effect of power extraction on the extractable nature was proved by ANOVA and Student test. The yields were also affected by time extraction. Different solvent (water, ethanol, methanol and ethyl acetate) were tested to evaluate the best extraction solvent according to the extractable nature. Highest polyphenols contents were obtained with methanol. The proportion of this solvent, time extraction and power extraction were optimized using the response surface methodology (RSM). A face-centered composite design (FCCD) was applied to evaluate the effects of these variables on the polyphenols and condensed tannins contents. For each experiment, the extraction yield, the total polyphenolic contents and the condensed tannins contents were quantified using colorimetric essays. The extracts were characterized by their reactivity to formaldehyde and reverse phase high pressure liquid chromatography (RP-HPLC). The highest polyphenols content was obtained at 156 W using 80\% of methanol during 5 min. For condensed tannins, the highest content of cyanidin was obtained at 182 W using 20\% of methanol during 3.66 min. RSM applied in MAE, permitted to develop green extraction process of polyphenols and tannins extracted, using lower microwave power and methanol proportion with a shortest time extraction and in the same time improve the quantity of extractables obtained from renewable natural resource.

Mild pyrolysis, operated at 200-300 degrees C in an inert atmosphere, is a promising technology to produce sustainable materials (i.e., heat treated woods for construction and building) and solid fuels (i.e., torrefied woods or biochars for combustion and gasification). To aid in process and reactor design, the aim of this work is to conduct thermal degradation kinetics of wood. A two-step kinetics model is developed to predict the elemental composition (C, H, and 0) and devolatilization dynamics of wood materials during heat treatment in a pilot-scale reactor by kinetic analysis. A hardwood poplar (Populus nigra) and a softwood fir (Abies pectinata) sever as feedstock, and the experiments are carried out at 200-230 degrees C with a heating rate of 0.2 degrees C min(-1) in a low-pressure environment (200 hPa). The predictions in the weight losses of the woods are in a good agreement with the experimental data. The evolutions of solids, volatiles, elements (C, H, and O), and the heating values of treated woods are further analyzed. The predictions suggest that the intermediate solid is the main product, and almost all the woods are converted when the treatment temperature is as high as 230 degrees C. The devolatilization process, which is responsible for the mass loss of wood, can be clearly identified, and the volatile liberation amounts from poplar and fir at 230 degrees C are 17.05 and 12.44 wt\%, respectively. The predicted HHVs of treated woods from the empirical formula are between 19.62 and 20.55 MJ kg and the enhancement factors at the end of treatment are between 1.01 and 1.07 which is close to torrefied wood after light torrefaction. During the treatment, the extents of decarbonization, dehydrogenation, and deoxygenation in fir are all smaller than those in poplar, resulting from the lower intensity of devolatilization in the former.

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.

In the building sector, the improvement of the heat and mass insulation of the walls can reduce the values of the global energy demand and the CO2 emission. A coupled one-dimensional heat and mass transfer model through a building wall was proposed in this study. The governing equations integrate the influences of Dufour and Soret effects and are numerically resolved using FORTRAN 90 and finite difference method in Crank-Nicolson scheme. Gauss-Seidel relaxation iteration method is used in order to generate the numerical solutions. The accuracy of the model was evaluated with experimental data on wooden wall and concrete wall from literature. A very satisfactory agreement is noted between the numerical predictions, experimental observations and physical phenomenon obtained. The model was further used to simulate the hygrothermal transfer through five tropical woods used as building walls in sub-Saharan African region after integration of outdoor conditions. These five woods have densities ranging from 430 to 800 kg/m(3) and the conditions of the interior air were fixed to maintain a comfortable state for the occupants. Twelve towns located within latitudes 4.33 degrees S to 12.37 degrees N in Sub - Saharan Africa were used to discuss the results given by the model. At the end, influences of anatomical direction, tropical wood types, wall thickness, latitudes of the locations and solar radiation on evolutions of temperature and moisture content in the wall are studied. Our results showed that these parameters have significant effects on temperature and moisture content propagation within the wall. Using a wooden wall of 5 cm thickness, it is possible to reduce significantly the effect of the exterior heat.

Tannin from mahogany bark extract contains polyphenols that could be used in adhesives. In this study, tannin (T) was reacted with resorcinol (R) and formaldehyde (F) at a ratio of 100:3:5 (w/w/w) under alkaline conditions to make an adhesive. The physical-chemical properties of tannin and TRF adhesive were assessed. Three-layer glued-laminated lumber (glulam) made with wood from jabon (Anthocephalus cadamba), pine (Pious merkusii), and sengon (Falcataria moluccana) was bonded using TRF with a glue spread of 280 g/m(2), cold pressed at 1.47 MPa for 4 h, and then clamped for 24 h. Glulam physical-mechanical properties were tested based on Japanese Agricultural Standard (JAS) 234-2007. Comparison of the physical properties of mahogany tannin and TRF showed that the solids content of mahogany tannin increased after becoming TRF. Compared with phenol resorcinol formaldehyde (PRF) resins, TRF had a similar appearance and specific gravity, but differed in solids content, viscosity, and gel time. Matrix-assisted laser desorption/ionization (MALDI)-time of flight mass (TOF) spectra revealed that mahogany tannin could be classified as hydrolyzable, and pyrolysis Gas Chromatograph-Mass Spectroscopy (GC-MS) showed that the phenolic content was 8.87\%. Copolymerization in TRF was indicated by a shift in wave number in Fourier transform IR, reduced percentage of the phenolic component, and increased pH and melting temperature. Mahogany tannin could be prepared for cold-set TRF glulam adhesive, and all glulams fulfilled JAS 234-2007 with regard to MC and MOR. Although TRF adhesive contained a small amount of resorcinol, it was suitable for low density wood, and in dry condition performed equal to PRF.

Adhesion of the barley husk to the underlying caryopsis requires the development of a cuticular cementing layer on the caryopsis surface. Differences in adhesion quality among genotypes have previously been correlated with cementing layer composition, which is thought to influence caryopsis cuticle permeability, the hypothesised mechanism of adhesion mediation. 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.

In this research furfuryl alcohol (FA) and polyethyleneimine (PEI) in different ratio were added to a tannin based adhesive in order to improve its moisture resistance. In order to characterize the functional groups involved, Fourier-transform infrared spectroscopy (FTIR) was used. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were used to study the thermal behaviour of the formulations. FTIR spectroscopy indicated the reaction of quebracho tannin with FA and PEI. The results of the TGA showed that the added FA and PEI increased the resistance to thermal degradation. DSC analysis showed that the added FA and PEI reduced the heat absorption peak. According to the tensile shear strength of the formulations, the adhesive formulation T-1 F-0.75 P-20 (mixing proportion: Tannin 1, FA 0.75, PEI 20\%) was able to satisfy the standards requirements (BS 1204-2) as a moisture resistant adhesive. Furthermore, this formulation presented the best tensile shear tests results and the least number of delaminated samples.

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.

The acetone/water extracted tannins from the bark were characterized by Matrix Assisted Laser Desorption/Ionization time of flight (MALDI-TOF) mass spectrometry and by Fourier Transform InfraRed spectroscopy (FTIR). The presence of fisetinidin, gallocatechin, and trihydroxyflavan monomers was observed for the first time. Flavonoid oligomers linked to sugars were found within K. ivorensis condensed tannins. An heptamer formed by mixed fisetinidin, trihydroxyflavan, three dihydroxyflavans, and a carbohydrate dimer including mannose was also identified for the first time in the bark of K. ivorensis. That mahogany hardwood species did not exhibit any antifungal activity against the white rot fungus Coriolus versicolor. However, bark powder decreased the radial fungus growth.

Key message Teak (Tectona grandis L.f.) is one of the most important tropical hardwood tree species, which is widely planted in Indonesia. Wood properties are strongly influenced by forest management conditioning further utilization of wood.

Context In Indonesia, teak wood has been supplied from the state forests (Perhutani) for long rotation teak and from community teak plantations for short rotation teak. Short rotation teak has been harvested at 7-10 years and long rotation teak at 40-60 years.

Aims This paper discusses the characterization of technical properties of short and long rotation teak wood based on the chemical, anatomical, physical, and mechanical properties.

Methods The properties of short rotation and long rotation teak woods were characterized by measuring their density, extractive contents, chemical composition, swelling, wettability, water sorption isotherm, decay resistance, anatomical properties, bending strength (modulus of rupture (MOR), modulus of elasticity (MOE)), and hardness.

Results The results indicate that short rotation teak was not particularly different in swelling, MOE and MOR, and Brinell hardness compared to long rotation teak, although it was less dense and less durable due to lower heartwood and extractive contents. Therefore, careful attention should be given to the use of short rotation teak in some wood-processing technologies.

Conclusion Lower wood density and durability of the short rotation compared to the long rotation teak will restrict its utilization to some extent for both indoor and outdoor applications. Fast-growing teak from community cannot be used as usual heartwood teak from Perhutani because of the very low proportion of useful heartwood in the stem.

The mechanical properties of a broad range of thermoset foams based on tannin were investigated through destructive compression tests, either with or without rigid plates glued to the opposite faces of the samples, and through a rather new, non-destructive, quasi-static method. The main objective was to compare both techniques, as well as the effect of the presence of plates, and to discuss the relevance of each for properly characterising the materials. Gluing stiff plates to the samples was found to be a key point for the appropriate determination of the elastic modulus of brittle foams, whereas it did not affect that of elastic-plastic foams. In contrast, the compressive strength did not depend on the kind of test. The results obtained by destructive compression were then compared to those of the new non-destructive technique, proving that the latter was suitable for characterising elastic-plastic foams but not brittle foams. However, the new method allowed determining Poisson ratio and loss factor, which had never been measured so far for this kind of materials.

Acid copper chromate fixation reactions on oak (Quercus castaneifolia C. A. Mey) sapwood were characterized by at least two distinguished reaction periods which differ in their kinetic behavior, particularly reaction rate. In this research, chemical rate equation parameters were studied in detail as a function of chromium fixation time. Theoretically, the kinetic data were distinguished between the adsorption and reduction reactions and consequently, the rate parameters were determined for each stage distinctly. The obtained results showed that at the investigated thermal range (25-33 degrees C), almost for every 3 degrees C increase in temperature the reaction duration has decreased 20.4 min for the first reaction period and 78 min for the second reaction period. Besides that, in all sample replications, up to 58.3\% of hydrogen ions function at the reduction reactions of the initial period, demonstrating that acidity (H+ ions) has a major effect on reaction rate constant. Accordingly, adsorption reactions of the hexavalent chromium at the starting point follow a pseudo-first-order kinetic reaction. Different to the adsorption reaction the Cr-VI reduction reaction is exothermic with a measured exothermal energy of 48.2kJ/mol.

The natural durability of wood is linked to its chemical composition and in particular the presence of metabolites called extractives that often possess chemical reactivity. For dealing with these compounds, wood degraders have developed detoxification systems usually involving enzyme families. Among these enzymes, glutathione transferases (GSTs) are involved in the decrease of the reactivity of toxic compounds. In this study, the hypothesis that the detoxification systems of wood decaying fungi could be indicators of the chemical reactivity of wood extracts has been tested. This approach has been evaluated using 32 wood extracts coming from French Guiana species, testing their antimicrobial ability, antioxidative properties, and reactivity against six GSTs from the white rot Trametes versicolor. From the obtained data, a significant correlation between the antimicrobial and antioxidative properties of the tested wood extracts and GST interactions was established. In addition, the chemical analysis performed on one of the most reactive extracts (an acetonic extract of Bagassa guianensis) has demonstrated oxyresveratrol as a major constituent. We were able to cocrystallize one GST with this commercially interesting compound. Taken together, the presented data support the hypothesis that detoxifying enzymes could be used to identify the presence of molecules of industrial interest in wood extracts.

The purpose of this study is to develop a numerical tool to predict the mass loss of a wood board during heat treatment as a marker of the process advancement. Mass loss dynamics during the wood heat treatment is experimentally obtained using a specially conceived equipment. The investigation method is applied on large scale wood samples whose radial and transvers dimensions are close to the boards used in industry. A two-step reaction mechanism is adopted to describe the behavior of wood thermodegradation. Model parameters are obtained by fitting the experimental data according to a new approach developed in this study for their optimal determination. The originality of the implemented modelling strategy is the establishment of a three-stage approach based on the analysis of wood thermal sensitivity depending on the treatment temperature range. Model equations are solved numerically by the commercial package Matlab\&$\#$39; software. A good agreement is achieved between the numerical predictions and the experimental data. The developed model and established kinetics can be used for heat treatment process and reactor design in industry to produce wood materials for their applications.

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 main objective of this paper is to develop a computational model and to simulate the drying of timber with a solar dryer. Two sets of equations have been established: one for the solar collector and the other for the drying chamber. The computed and measured outlet temperatures of the solar collector were compared. A very satisfactory prediction by the model is observed. The theoretical variations of the relative humidity and temperature of the air inside the drying chamber were computed and the analyses gave satisfactory physical meanings. The drying kinetic is a little faster. Using the solar collector, the final moisture content of the wood stack of iroko species (Chlorophora excelsa) is lower than the one obtained without utilization of the solar collector. The proposed modelling can be used to design and model other solar dryers.

Condensed flavonoid tannin-based foams from quebracho tannin extract have been developed using a new method of expansion based on fire-fighting or tunneling foams, where a foam concentrate forms a stable liquid foam. 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. The use of this new approach for preparing tannin-based rigid foams avoids the problem of shrinkage presented by many other formulations where physical or chemical foaming is employed.

Wood decay fungi have complex detoxification systems that enable them to cope with secondary metabolites produced by plants. Although the number of genes encoding for glutathione transferases is especially expanded in lignolytic fungi, little is known about their target molecules. In this study, by combining biochemical, enzymatic and structural approaches, interactions between polyphenols and six glutathione transferases from the white-rot fungus Trametes versicolor have been demonstrated. Two isoforms, named TvGSTO3S and TvGSTO6S have been deeply studied at the structural level. Each isoform shows two distinct ligand-binding sites, a narrow L-site at the dimer interface and a peculiar deep hydrophobic H-site. In TvGSTO3S, the latter appears optimized for aromatic ligand binding such as hydroxybenzophenones. Affinity crystallography revealed that this H-site retains the flavonoid dihydrowogonin from a partially purified wild-cherry extract. Besides, TvGSTO6S binds two molecules of the flavonoid naringenin in the L-site. These data suggest that TvGSTO isoforms could interact with plant polyphenols released during wood degradation.

The floor and north wall are insulated and painted in black. The dryer is very simple to build and electrical energy is only used for the fan. Applications are done on three tropical woods with 50 mm thick most utilized in Central Africa: obeche (Triplochilon scleroxylon), iroko (Chlorophora excelsa) and sapele (Entandrophragma cylindricwn). Comparisons between the numerical results and those experimentally obtained are given and the performances of this solar dryer are discussed under the weather conditions of seven towns in Central Africa region located in six different countries. Satisfactory agreement between experimental and numerical results is then obtained.

In this paper, \"green\" tannin-furanic foams were prepared based on formulations free of formaldehyde and foaming agent, aiming at obtaining the best thermal insulators as possible with the highest mechanical resistance. Both of these properties are antagonistic, since low thermal conductivity requires high porosity whereas high mechanical properties require low porosity. Thus, experimental design was applied for the first time to this kind of formulations. Thanks to a limited number of experiments suggested by a rational mixture design, the experimental responses: thermal conductivity, elastic modulus and compressive strength were modelled and predicted based on the relative proportions of three main ingredients of the formulation. The results revealed that the formulations containing a high proportion of furfuryl alcohol, a moderate proportion of tannin and a low level of catalyst led to the best compromise between properties having opposed trends. Thus, optimised foams presented a thermal conductivity of 0.039 W m(-1) K-1 and compression strength of 0.07 MPa. The reliability of the model used was successfully validated by additional tests. This proved it to be a very useful tool for developing environment-friendly tannin-furanic foams with desired features.

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.

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).

Liquid composite molding (LCM) processes are being used in manufacturing near-net-shape, geometrically complex composite parts. One of the current obstacles to a larger scale application of these processes is the formation of defects such as voids during resin injection. To reach aeronautic requirements or short injection cycles in the automotive industry, entrapped air in the final part before curing has to remain as low as possible. Air entrapment will depend on the fibrous structure and on the injection parameters, or more precisely on the fluid pressure and the flow front orientation with respect to the fibrous direction. A key parameter for production of structural composite parts is air entrapment, since high void content could lead to mechanical softening, early failure, or part rejection. The quantitative simulation of the void formation is important for proper design and selection of material and processing parameters to minimize such voids in the composite materials. Despite several advancements in voidage predictions via modeling and simulations, the void formation mechanisms in RTM and similar processes are still not fully understood. In this study, a review of current approaches to modeling and simulation of void formation and unsaturated flow in the liquid composite molding process is presented. We examine modeling efforts considering all the mechanisms involved such as void formation and transport, bubble compression, and gas dissolution. In particular, the capillary number is identified as a key parameter for void formation and transport. The influence of voids on the global resin flow is also investigated and a state-of-the-art is presented.

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.

Tannins as herbal extracts are a good alternative for green chemistry. They are found aplenty in some plant species and can be extracted by simple methods. The tannins main feature and advantage is their phenolic structure which is very similar to synthetic phenols. Another key feature of tannins is their actions as antioxidants. The use of tannins is often connected to one of these features. They are now actively used in leather tanning, adhesive making (especially wood adhesives), fisheries, beverages manufacturing, animal feed and many others. Considerable amounts of research has also been recently conducted on the possibility of using tannins in the manufacture of biosourced foams, wood preservatives, corrosion inhibitors, polyurethane surface coatings, epoxy adhesives, binders for Teflon coatings and etc. This paper deals with different uses of tannins and with the latest research which has been done on this subject.

Fine hemp fibers (cottonized hemp) were processed using steam explosion. The quantification of the defibration rate was performed by image processing.

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 objective of this paper is on the one hand to study the effect of heat processing (30 to 130 degrees C for 2 h) on the stability and antioxidant activity of six flavonoids (rutin, naringin, eriodictyol, mesquitol, luteolin, and luteolin 7-O glucoside), and on the other hand to establish the relation structure-activity-stability of these compounds. The dependency on temperature of the six kinetics was well described by the Arrhenius law and the main parameters provided by this model are determined and compared in this paper. Activation energies found were 107.3 kJ/mol for rutin, 100.6 for naringin, 33.3 for mesquitol, 68.2 for eriodictyol, 51.4 for luteolin, and 120 for luteolin 7-O-glucoside. The data collected showed that glycosylated flavonoids are more resistant than aglycon flavonoids to heat treatment. Moreover, it was also observed that despite the total degradation of some flavonoids, the treated solutions still have an antioxidant activity.

Practical applicationFlavonoids are mainly consumed in processed foods. Thus, flavonoids often undergo heat processing. Knowing the thermal stability and the evolution of their antioxidant activity are particularly relevant in the field of food processing. The results of this study allow information to be collected on the relationship between heat stability-flavonoid structure and antioxidant activity. This information will be useful for the formulation of new food products or for the design of new food processes.

The aim of this work was the formulation of adhesives for particleboards based on tannins extracted from industrial lignocellulosic wastes, namely chestnut shell, chestnut bur and eucalyptus bark. The interest was centred on the possibility of completely removing formaldehyde from adhesive formulations. For this, hardener alternatives to formaldehyde were used: tris(hydroxymethyl)nitromethane (TRIS), glyoxal (GLY) and hexametilentetramine (HEX). The influence of the type and concentration of the hardener and pH on adhesive gel time and pot-life were studied. A comparative structural characterization of the adhesives was performed by 13C-NMR spectroscopy. Thermomechanical analyses (TMA) tests were carried out as an indication of the final strength of the adhesive systems. Particleboards type 2 of interior use (EN 312) were manufactured with adhesives based on chestnut shell tannins alone or mixed with chestnut bur/or eucalyptus bark tannins. Free-formaldehyde was determined, and boards were prepared with TRIS, GLY and HEX tannin adhesives were classified as E0.

Fire-resistant elastic materials made from tannin, a natural polyphenol extracted from tree barks, and having the appearance and the consistence of rubber are described. They can be produced in any dimension and with any shape based on a quite simple protocol, only consisting in mixing tannin, water and ethylene glycol, in the presence of a low amount of p-toluene sulphonic acid. After curing at 85 degrees C in an oven and subsequent drying, black elastic blocks are recovered whose mechanical properties can be easily adjusted from the proportions of the ingredients, especially with the amount of ethylene glycol acting as plasticiser. As a result, materials from extra-soft to hard can be obtained. Their retardant performance towards fire is demonstrated, a well-known feature of phenolic compounds here observed for the first time with an elastic material. Physicochemical analyses are performed and explain the chemistry behind the performances of these new biosourced materials.

Isocyanate-free polyurethane resins biosourced to a very high percentage level were prepared by the reaction of aminated mimosa tannin extract with commercial mimosa tannin extract prereacted with dimethyl carbonate. The reaction took place with ease at ambient temperature. Indications were that the polyurethanes obtained formed a hard film when cured at a temperature higher than 100 degrees C. Furthermore, the carbohydrate fraction of the tannin extract also appeared to be carbonated and reacted to generate isocyanate-free polyurethane linkages with the aminated tannins. This indicated that not only the polyphenolic fraction of the tannin extract, but also its other major component, can be used to prepare polyurethane resins. Flavonoid monomers and oligomers carbonated at different levels, both unreacted and urethane-linked to aminated flavonoid monomers and oligomers, were identified by FTIR and MALDI-TOF spectrometry.

The lignin samples were analyzed by FFIR, H-1 and C-13 NMR spectroscopy, 2D NMR: HSQC spectroscopy, CHN analysis, molecular weight distribution analysis; GPC and thermal analysis; DSC and TGA. The lignin modification has reduced the hydrophobicity of its complex structure by providing better quality lignin with smaller fragments and higher solubility rate in water (D-AHCEOL.: 42\%\> D-AHEOL: 25\%). It was revealed that the modification of lignin has improved their structural and antioxidant properties, thus venture their possible applications.

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 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.

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.

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)).

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.

The chemical modification of tannin through epoxidation is a way to develop new applications for tannins and to improve tannin resins performances. In this paper the influence of reaction conditions was studied. Commercial tannin bark extract was epoxidized.

Condensed tannins from pine (Pinus radiata), mimosa (Acacia mearnsii), and quebracho (Schinopsis lorenzii) were modified with propylene oxide (PO) via a mild derivatization (20 degrees C, 24 h). The hydroxypropylation to three PO/C-15 ratio (1, 2, 3) produced polyphenolic derivatives in reasonable yields (60-90\%). Evidense of modification was described by functional group analysis, and tannin biological properties (binding-, and antioxidant-capacity). Isolated products were characterized by physicochemical methods (solubility test, molecular weight distribution, and thermal analysis). H-1 NMR provided evidence of strong structure-properties relationship in function of the A-ring type, and C -\> C linkage features. Pine tannin fractions exhibited the best PO-uptake. Acetoxy signal intensity of acetylated derivatives revealed that mimosa and quebracho tannins are less reactive polyflavonoids toward hydroxypropylation at room temperature. Thermal behavior, solubility, and antioxidant-, and binding-capacity were affected by the modification. However, pine tannins behavior differ from those highly purified polyflavonoids.

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.

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 permeability of textile reinforcements is a crucial input to the simulation of a composite material process. In this paper, we present an accurate simulation approach for identifying fiber reinforcement permeability in the resin transfer moulding (RTM) process. The Gauss-Newton-Levenberg-Marquardt method was utilized to identify the permeabilities of fibrous reinforcement. Knowing the boundary conditions, the permeability can be deduced from pressure values at some given positions through the part. Starting from the initial estimate of permeability, the inverse method begins by solving the direct problem. The solution gives the pressure field everywhere in a composite sample. The calculated pressure field is then compared with an analytical pressure based on a criterion. The permeability is modified iteratively so as to minimize this criterion until the desired accuracy is achieved. A comparison between experimental and the computed parameters is used as convergence criteria in the iterative inverse technique, and good agreement is found.

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.

The synthesis and the properties of the first polymerised High Internal Phase Emulsions (polyHIPEs) derived from co-reacted tannin and furfuryl alcohol resin, are reported in this paper. Such highly porous thermoset polymers were obtained by emulsion-templating in the form of strong monoliths, using 70 vol\% of cyclohexane as the internal phase. The volatility of the latter made the preparation process very simple, not requiring the usual long washing steps encountered in the synthesis of most polyHIPEs. The structure of these new materials was investigated by different techniques as a function of the amount of surfactant in the initial formulation. The pore sizes exhibited clear trends that were explained. The materials were found to be interesting thermal insulators whereas presenting outstanding mechanical properties, among the highest ever reported for porous polymers.

The solubility in water and carbohydrates/lignin composition after hydrolysis of wood welded by linear friction welding was studied. Welded beech (WB) and welded spruce (WS) were analyzed at welding times (Wt) of 1, 1.5, 2, 2.5, 3 s, and 2, 4, 6, 8, 10, 12 s, respectively. Scratched welded material was first extracted in water, dried, cryo-milled, and then hydrolyzed with sulfuric acid. Maximal percentages of solids dissolved in water were 17.7 and 10 for WB and WS and 2.2 and 1.4 for un-welded beech and spruce, respectively. Among water extracts, lignin, mono-oligosaccharides, acetic acid, vanillin, furfural, 5 hydroxymethylfurfural (5HMF), and syringaldehyde were quantified. Maximal percentages of water soluble lignin in WB and WS were 5 and 3.6, respectively; molecular weight and polydispersity were also determined. Regarding carbohydrates in the water extracts, a maximum of 1.4 \% oligosaccharides in WB and 1 \% monosaccharides in WS were detected. After hydrolysis, an increase in the amount of Klason lignin and a progressive diminution of some sugars take place at consecutive Wt of WB and WS. This study allows explaining to a good extent the behavior of welded joints face to liquid water. Moreover, the degradation of certain wood components is clearly presented.

Different kinds of tannin-based foams were developed in the recent past with fisetinidin/robetinidin-type tannins extracted from mimosa (Acacia mearnsii) or quebracho (Schinopsis lorentzi) bark; or procyanidin-type tannins from pine (Pious pinaster and Pinus radiata). These biobased porous products revealed excellent properties similar to their synthetic counterparts in many applications. Norway spruce (Picea abies) bark is another large potential source of procyanidin-type tannins.

This paper deals with the study of spruce tannins reactivity for rigid foam formulations.

The amounts of blowing agent (pentane) and catalyst (para-toluene sulphonic acid) were varied with the aim of monitoring the changes in the curing processes of foams.

A thermal analysis carried out by differential scanning calorimetry revealed an almost finished reaction at the time of the peak temperature, occurring from the reaction of foaming, whereas conversion results derived from dielectric analysis and rheological tests indicated that curing process began after the occurrence of maximum temperature. With increased catalyst concentration, the start of curing process was accelerated, while a raised amount of pentane delayed the curing process. The curing process of the tannin-based foams was divided into three characteristic phases: the induction phase, the expansion phase, and the structure-strengthening phase.

The performance of three techniques, conventional maceration at room temperature, infusion and microwave assisted extraction, was evaluated to extract polyphenols, condensed and hydrolysable tannins from Moroccan barks of Acacia mollissima. A comparison of these methods was performed using colorimetric assays. For each technique, the effect of extraction conditions on the yield extracts was evaluated. The variables studied are: solvent nature, barks ages, time extraction, power extraction and heat interaction with solvent nature and barks ages. This study proved that the choice of solvent extraction was a relation of the extraction method used and the extractible nature (polyphenols, condensed or hydrolysable tannins). Methanol was the best solvent to extract tannin and polyphenols using maceration at room temperature, and ethanol was the best for infusion at 60 degrees C. Microwave was more selective to extract polyphenols and tannins under extraction solvent used. Highest polyphenols contents was obtained using methanol. For condensed and hydrolysable tannins, the highest were obtained using water. The polyphenols contents extracted using maceration was closed to the yield obtained with microwave, 354 mg GAE/g bark, 442 mg GAE/g bark, respectively. This study proved the pertinence of traditional methods to extract polyphenols and tannins compared to the new extraction method (microwave). The best polyphenols yields, condensed and hydrolysable tannins were obtained by microwave followed by the yield obtained by maceration and finally the yield obtained by infusion.

Various parameters, including the amount of procyanidins, were varied in order to observe the effect of changes in the density of the foam, on the structure its pores, and on the homogeneity, compressive strength, and compressive modulus of the foams. It was found that an optimum amount of spruce tannin exists, which results in a foam with the lowest density whereas the amount of cross-linker affects homogeneity, and the foam morphology is defined by the surfactant A partial replacement of pine tannin with spruce tannin decreased the foaming temperature and led to decreased compressive strength and a decreased compressive modulus of the foams. The main attribute affecting the reaction was the amount of polyphenols, or the amount of impurities (cellulosic sugars) present in the tannin extract.

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.

Such change of behaviour was observed by many different techniques such as viscosity, electron microscopy, mercury intrusion, and mechanical studies. We show and explain why this critical oil fraction is the one leading to the strongest and most homogeneous porous monoliths.
