Wood Template

Transparent wood composites (TWCs) are a new class of light-transmitting wood-based materials composed of a delignified wood template that is infiltrated with a refractive- index-matched polymer resin. Recent research has focused primarily on the fabrication and characterization of single-ply TWCs. However, multi-ply composite laminates are of interest due to the mechanical advantages they impart compared to the single ply. In this work, 1- and 2-ply [0°/90°] TWC laminates were fabricated using a delignified wood template (C) and an acetylated delignified wood template (AC). The optical and mechanical properties of resultant C and AC TWC laminates were determined using ultraviolet-visible spectroscopy (UV-Vis) and tensile testing (5× replicates), respectively. In addition, the ability of classical lamination plate theory and simple rule of mixtures to predict multi-ply tensile modulus and strength, respectively, from ply-level mechanical properties were investigated and are reported herein. Experimental results highlight tradeoffs that exist between the mechanical and optical responses of both unmodified and chemically modified TWCs. Template acetylation reduced the stiffness and strength in the 0° fiber direction by 2.4 GPa and 58.9 MPa, respectively, compared to the unmodified samples. At high wavelengths of light (>515 nm), AC samples exhibited higher transmittance than the C samples. Above 687 nm, the 2-ply AC sample exhibited a higher transmittance than the 1-ply C sample, indicating that thickness-dependent optical constraints can be overcome with improved interfacial interactions. Finally, both predictive models were successful in predicting the elastic modulus and tensile strength response for the 2-ply C and AC samples.

Porous Ni0.5Zn0.5Fe2-xCrxO4 (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5) ceramics were prepared by a sol-gel method using basswood as the mold. At the same time, Ni0.5Zn0.5Fe2-xCrxO4 nanocrystalline powders were obtained by sintering the gel in oxygen at high temperature. The result of the XRD test showed that all samples presented the single-phase of the cubic spinel structure. With the increase of doping amount x, both porous ceramics and nanopowders decreased their grain size; At the same doping amount, the grain size of powder ferrites was about twice as large as that of porous ceramics. The magnetic test results showed that with the increase of doping amount x, the coercivity values increased monotonously and the saturation magnetization values decreased monotonously for all samples. Under the same doping content, the saturation magnetization values were lower but the coercivity values were higher as compared to the powder ferrites.

We report a bulky macroporous TiO2particles with cellular structure prepared in the presence of wood slices as template. Firstly, TiO2sol was coated onto the wood slices by repeated dip-coating process. Then, after calcinations at 550°C, the wood template could be removed, and the bulky TiO2structure was obtained. The prepared samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), and transmission electron microscope (TEM) techniques. XRD pattern confirmed the crystalline phase of the wood-templated TiO2is anatase phase. And interestingly, from the observation of SEM image, the wood-templated TiO2inherited the initial cellular structures of birch lumber (B. albosinensis Burk), and numerous macropores were observed in the sample. Meanwhile, the wood-templated TiO2presented a superior photocatalytic ability to decompose Rhodamine B (RhB) under ultraviolet irradiation.

The adsorption effect of NO3-, SO42- or PO43- about As (V) on the novel porous biomorph-genetic composite of Fe2O3/Fe3O4/C was prepared with eucalyptus wood template (PBGC-Fe/C) was analyzed and considered. The results show that NO3-, SO42- and PO43- have different change trend onto the PBGC-Fe/C adsorbent under initial As (V) concentration of 5, 10, 50mg/L, the competitive adsorption capacity is: PO43-> NO3-> SO42-. And with increasing of NO3-, SO42- and PO43- concentration, the competitive adsorption phenomenon is more violent.
