Xylem fibers are highly elongated cells that key constituents of wood, play major physiological roles in plants, comprise an important terrestrial carbon reservoir, and thus have enormous ecological economic importance. As they develop, from fusiform initials, their bodies remain the same length while tips elongate intrude into intercellular spaces. To elucidate mechanisms tip elongation, we st...

This study compared oxidative delignification of birch kraft pulp fibers to from acid hydrotropic fractionation (AHF) using p-toluenesulfonic (p-TsOH). Under oxygen at 20% consistency, AHF pulps with lower hemicellulose content showed higher than similar lignin despite its residual (cellulosic enzymatic lignin, CEL) being less reactive fewer ?-O-4 ether aryl linkages based on 2D13C-1H nuclear m...

The production of the H(2)O(2)-generating enzyme pyranose oxidase (POD) (EC 1.1.3.10) (synonym, glucose 2-oxidase), two ligninolytic peroxidases, and laccase in wood decayed by three white rot fungi was investigated by correlated biochemical, immunological, and transmission electron microscopic techniques. Enzyme activities were assayed in extracts from decayed birch wood blocks obtained by a n...

This review deals with recent works on the process and technological aspects of wood-plastic composites (WPCs) manufacturing.WPCs relate to any that are built from wood non-wood fibers thermoplastic polymers. Recent progress relevant has been reviewed in this article. The WPC, such as raw materials, fabrication, mechanical, physical, thermal, morphological properties, were outlined comprehensiv...

The aim of the present study was to investigate effects fiber content and then silane treatment on mechanical performance natural composites recycled acrylonitrile–butadiene–styrene (ABS) provided by automotive sector. Wood palmyra fibers were used as fillers in 10% 20% composites. treated with N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane improve interfacial adhesion between polymer matrices....

BACKGROUND Xylan has been identified as a physical barrier which limits cellulose accessibility by covering the outer surface of fibers and interfibrillar space. Therefore, tracking xylan is a prerequisite for understanding and optimizing lignocellulosic biomass processes. RESULTS In this study, we developed a novel xylan tracking approach using a two-domain probe called OC15 which consists o...

We report the discovery of the hydrotropic properties of a recyclable aromatic acid, p-toluenesulfonic acid (p-TsOH), for potentially low-cost and efficient fractionation of wood through rapid and near-complete dissolution of lignin. Approximately 90% of poplar wood (NE222) lignin can be dissolved at 80°C in 20 min. Equivalent delignification using known hydrotropes, such as aromatic salts, can...

Abstract The paper-forming properties of the fibrous suspension and physical mechanical characteristics finished types paper largely depend on type initial plant material. Depending what purpose it is necessary to obtain paper, a composition made from semi-finished products origin in various proportions. Basically, produced two, three, or more products, forming according fibers, sometimes one p...
