Electrospinning Cellulose and Cellulose Derivatives
Polymer Reviews, 2008Many solvents suitable for wet or dry spinning of cellulose and cellulose derivatives have also been investigated as solvents for electrospinning. Solvents for cellulose are not completely volatile and have required coagulation steps to ensure complete removal of the solvent from electrospun fibers and produce stable fibers.

Multilayers of cellulose derivatives and chitosan on nanofibrillated cellulose
Carbohydrate Polymers, 2014The aim of this work was to study the effect of solution conditions and polysaccharide structure on their Layer-by-Layer (LbL) deposition on nanofibrillated cellulose (NFC). Multilayer build-up of cellulose derivatives and chitosan on NFC model surfaces was studied using Quartz Crystal Microbalance with Dissipation (QCM-D) and Colloidal Probe ...

This article discusses advances in understanding the structural and physicochemical characteristics of suspensions of cellulose crystallites prepared by acid hydrolysis of natural cellulose fibres. Consideration of recent developments in visualization of crystallite ultrastructure may provide clues to suspension behavior.

Pyrolysis of cellulose under vacuum and atmospheric pressure gave a tar containing various amounts of 1,6-anhydro-β-D-glucopyranose, 1,6-anhydro-β-D-glucofuranose, α- and β-D-glucose, 3-deoxy-D-erythro-hexosulose, oligo- and polysaccharides, and some dehydration products.

Cellulose, polymers of glucose organized into long fibrils, forms the bulk of the world's biomass. But the identity of the enzyme that makes this critical substance has been uncertain. In this week's issue, [ Arioli et al .][1] report the first confirmation that the gene CelA is indeed a cellulose synthase, and Carpita and Vergara, in their research ...

Abstract Cellulose is one of the major commercial products of Sweden and constitutes the most abundant of the natural polymer systems. Thus, it is of interest to review the molecular design and architecture of cellulose with particular reference to the controls of its biosynthesis.

Oxidation of macroradicals in celluloses and cellulose nitrate
Polymer Science U.S.S.R., 1990The ESR method has been used to study the reaction of oxidation of macroradicals in UV- and γ-irradiated cotton cellulose and cellulose nitrate with oxygen dissolved in these polymers. The degree of oxidation of the alkyl radicals in the polymers studied did not exceed 30% which is apparently linked with the diffusion difficulties of access of oxygen ...

Bioenergy Cellulosic bioenergy, obtained from the lignocellulose that makes up nearly half of plant biomass, has considerable potential as an environmentally friendly energy source, but it still requires substantial resources to produce. Robertson et al.

Publisher Summary Cellulose is a high polymer of β-1,4-linked D-glucose residues. All methods for the isolation, purification, and solubilization of cellulose seem to depolymerize the molecule more or less. However, by improved methods giving a minimum of depolymerization, higher values for the degree of polymerization (DP) are obtained.
