Bamboo, a fast-growing grass, has a higher strength-to-weight ratio than steel and concrete. The unique properties of bamboo come from the natural composite structure of fibers that consists mainly of cellulose microfibrils in a matrix of intertwined hemicellulose and lignin called lignin-carbohydrate complex (LCC). Here, we have used atomistic simulations to study the mechanical properties of ...

The aim of this paper is to report the impact of the addition of cellulose nanocrystals on the barrier properties and on the migration behaviour of poly(lactic acid), PLA, based nano-biocomposites prepared by the solvent casting method. Their microstructure, crystallinity, barrier and overall migration properties were investigated. Pristine (CNC) and surfactant-modified cellulose nanocrystals (...

Correspondence to: Shuai Zhang email: [email protected] ABSTRACT LiOH/urea/thiourea aqueous systems have been successfully applied to the dissolution of bacterial cellulose (BC) and alginate (AL) to prepare blend fibers. Morphology, compatibility and mechanical properties of the blend fibers were investigated by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT...

Cellulose particles, their derivatives and composites have special environmentally benign features and are abundant in nature with their various applications. This review paper introduces the essential properties of several types of cellulose and their derivatives obtained from various source materials, and their use in electro-responsive electrorheological (ER) suspensions, which are smart flu...

This paper describes the results obtained on the preparation of films composed of linter cellulose and the corresponding acetates. The acetylation was carried out in the LiCl/DMAc solvent system. Films were prepared from a LiCl/DMAc solution of cellulose acetates (degree of substitution, DS 0.8-2.9) mixed with linter cellulose (5, 10 and 15 wt %). Detailed characterization of the films revealed...

There are many reports on the application of different hydrocolloids in the production of leavened breads; most of which show positive effects on bread quality. However, there is little information to prove such effect on flat breads. The main aim of this study was to improve the quality of Barbari dough and bread (Iranian flat bread) in terms of texture, taste and general acceptability of fres...

In this study CuO nano sheets were prepared using the cellulose extracted from green synthesis (cotton) as a novel me project. Structural properties were examined using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Ultra Violet (UV-Vis). The optimum copper oxide peak was at 2 theta 〖35.44〗^°corresponding to (1 ̅11) while for the cellulose was 〖22.8〗^°correspon...

Hydrolysis of cellulose to glucose in aqueous media catalyzed by the cellulase enzyme system suffers from slow reaction rates due in large part to the highly crystalline structure of cellulose and inaccessibility of enzyme adsorption sites. In this study, an attempt was made to disrupt the cellulose structure using the ionic liquid (IL), 1-n-butyl-3-methylimidazolium chloride, in a cellulose re...

Method of preparation and some properties of amorphous cellulose nanoparticles (ANP) have been described in this paper. It was shown that ANP have spherical shape and are characterized by high degree of pantamorphia, low DP and increased content of sulfonic groups. The amorphous nanoparticles of cellulose are completely hydrolyzed by cellulolytic enzymes with forming of glucose. Concentrated pa...
