AbstracG-Crystal morphology of thermoplastics is known to be strongly influenced by the presence of solid suhstrntes like fibers or fillers. For wood, this interphase development is govemed by the chemical composition of the thermoplastic and substrate. The crystallization of PP/MAPP blends WBS observed using polarized light microscopy and quantified using DSC and DM.4. Techniques are presented...

Natural dyes are gaining interest due their expected low risk to human health and to the environment. In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addit...

A novel biorefinery concept based on the fractionation of woody biomass in a γ-valerolactone (GVL)/ water binary mixture is introduced. Under optimal GVL/water ratio, Eucalyptus globulus wood was effectively fractionated in a single step into its principal components. The pulp fraction, characterized by high yield, high cellulose purity and high bleachability, was directly spun to produce regen...

Although poplar is widely used for genomic and biotechnological manipulations of wood, the cellular basis of wood development in poplar has not been accurately documented at an ultrastructural level. Developing secondary xylem cells from hybrid poplar (Populus deltoides x P. trichocarpa), which were actively making secondary cell walls, were preserved with high pressure freezing/freeze substitu...

Activated carbon fibers were prepared from liquefied wood through stream activation. The effects of activation temperature and time on the microstructure and surface functional groups of the liquefied wood activated carbon fibers (LWACFs) were studied using analysis of burning behavior, X-ray diffraction, nitrogen adsorption-desorption isotherms, Xray photoelectron spectroscopy, and SEM. The re...

Wood, or secondary xylem, is a water-conductive and supportive vascular tissue highly characteristic of trees. In addition to parenchymatous cells adapted for storage and transport functions, wood is mainly composed of various vertically elongated cell types. These are classified either as tracheary elements or fibers, both of which are characterized with extensive secondary cell wall thickenin...

Cellulose fibers, cell wall fragments and cellulose microfibrils can be used as reinforced materials for biocomposite manufacture. Understanding nano-mechanical properties of those materials will be very useful to show their full theoretical potential. Nanoindentation testing is a technique that determines the mechanical properties of a material in the sub-micron/nano scale. The test involves p...

The withdrawal resistance of screws in heat-treated and reinforced laminated veneer lumber (RLVL) was determined in the radial, tangential, and transverse directions. For this reason, laminated veneer lumber (LVL) and RLVL with carbon fibers were produced from heattreated oak (Quercus petraea (Liebl.)) veneers using phenol formaldehyde as the adhesive. Wood samples were heat-treated at 140, 170...
