The characterization of the dielectric properties wood–polymer composites (WPCs) is essential to understand their interaction with electromagnetic fields and evaluate potential use for new applications. Thus, spectroscopy monitored evolution WPCs over a wide frequency range 1 MHz GHz. were prepared using mixtures different proportions (40%, 50%, 60%) wood bark fibers from various species, high-...

The angle between helical windings of microfibrils in the secondary cell wall of fibers and the long axis is called microfibril angle (MFA). Stiffness of wood depends on variations in the MFA. The large MFA shows low stiffness, which is found in juvenile wood and this character make threes vulnerable to high winds breaking. Timber containing a high proportion of juvenile wood is unsuitable for ...

NAC domain transcription factors are important regulators that activate the secondary wall biosynthesis in wood formation. In this work, we investigated the possible functions of an NAC family member SECONDARY WALL-ASSOCIATED NAC DOMAIN PROTEIN2 (PtSND2) using chimeric repressor silencing technology. Reverse transcription-polymerase chain reaction, subcellular localization and transcriptional a...

Longitudinal compression can help wood form some folds on the wood cell walls after a suitable softening procedure. These folds can enhance the oneand multi-dimensional bending performances of wood. The longitudinal compression properties of alkali-treated juvenile and mature northeast Chinese ash (Fraxinus mandshurica Rupr.) were analyzed. Elastic and elastic-plastic stages were inferred from ...

This study was devoted to the development of pulp Luffa Cclindrica and its characterization paper (annual plant fiber of the family Cucurbitaceae). Baking at soda helps to achieve a high level of delignification (Kappa ≤ 10) and high yield (≈ 67%).The beatability stack Valley is comparable to refined wood fibers, the fibers develop a normally time with good hydrophilic pro...

Background: In the face of increasing wood demand in climate change context, fast-growing species are considered as a current solution. However, ability agroforestry systems to contribute bridging gap between and supply mitigation also depends on properties species, which vary based locality. The objective this study was evaluate potential Acacia auriculiformis A. Cunningham ex Benth. Benin whi...

The aim of the paper was to examine the application of regenerated cellulose fibers as a reinforcement material in particleboard production. Single-layer, 10 mm thick panels, with the density of 800 kg/m3 were produced with addition of regenerated cellulose fibers in the range of 0 do 15% by mass during panels’ production. The mechanical and physical parameters of the produced panels were teste...

Three alkali swelling methods were used to treat two kinds of kraft pulp fibers. The morphological and chemical properties of the treated fibers were elucidated in terms of alkali concentration, with the aim of developing bulky paper and conserving wood resources. The effects of beating before and after alkali swelling were examined. The water retention value of fibers increased when higher con...

Wood is the most abundant biomass produced by land plants. Dissection of the molecular mechanisms underlying the transcriptional regulation of wood formation is a fundamental issue in plant biology and has important implications in tree biotechnology. Although a number of transcription factors in tree species have been shown to be associated with wood formation and some of them are implicated i...

The successful development of durable wood-plastic composite (WPC) cladding poses a challenge, hence investigating the effects water immersion-freeze-thaw treatment on physical properties, flexural strength (FS), and morphology wood-recycled polypropylene composites. behavior wood plastic is difficult to predict due complexity structure material. Wood consists cells (fibers) arranged in an intr...
