CELL 256: Role of dispersion and polar interactions in the adsorption of cellulases onto lignin
Residual lignin in pretreated biomass hinders its enzymatic hydrolysis. Nonionic surfactants are known to have beneficial effects on the enzymatic hydrolysis of lignocellulosic biomass but their mechanisms of action at the ... -
Cellulose derivatives with a low degree of substitution
(United States Patent and Trademark Office, 1996-06-04)The invention is directed to the formation of cellulose derivatives using homogenous phase reaction conditions. Cellulose is dissolved using DMAc/LiCl and a reagent system is added to promote the acylation of an appropriate ... -
Changes in the Chemical Composition and Decay Resistance of Thermally-Modified Hevea brasiliensis Wood
(PLOS, 2016-03-17)In this study the effect of thermal treatment on the equilibrium moisture content, chemical composition and biological resistance to decay fungi of juvenile and mature Hevea brasiliensis wood (rubber wood) was evaluated. ... -

Folic Acid-Conjugated Cellulose Nanocrystals Show High Folate-Receptor Binding Affinity and Uptake by KB and Breast Cancer Cells
(American Chemical Society, 2018-10-24)The study evaluates cellulose nanocrystals (CNCs) as nanocarriers for targeted, intracellular delivery of molecular agents. CNCs were labeled with fluorescein-5′-isothiocyanate as an imaging agent and conjugated to folic ... -
An “ideal lignin” facilitates full biomass utilization
(AAAS, 2018-09-28)Lignin, a major component of lignocellulosic biomass, is crucial to plant growth and development but is a major impediment to efficient biomass utilization in various processes. Valorizing lignin is increasingly realized ... -
Imparting functional variety to cellulose ethers via olefin cross-metathesis
(The Royal Society of Chemistry, 2015-04-09)Olefin cross-metathesis is a valuable new approach for imparting functional variety to cellulose ethers. Starting from commercially available ethyl cellulose, terminally unsaturated alkyl groups were appended as metathesis ... -
The Influence of a Thermal Treatment on the Decay Resistance of Wood via FTIR Analysis
(Hindawi, 2018-01-28)The decay resistance of wood can be improved via a vacuum heat treatment. The amount of nutrients from cellulose, hemicellulose, and lignin and amount of sugars needed by the fungi during their growth were investigated. ... -
Intra-Ring Compression Strength of Low Density Hardwoods
(Universidad del Bío-Bío, 2006)Engineered wood composites are being crafted with increasingly smaller and smaller components, yet a search of the literature indicates a lack of intra-ring mechanical property data for almost all commercial wood types, ... -
Multifunctional cellulose esters by olefin cross-metathesis and thiol-Michael addition
(Royal Society of Chemistry, 2016-04-25)Olefin cross-metathesis (CM) has been shown to be a versatile, mild, modular, and efficient approach to polysaccharide modification. One issue with regard to this approach is the susceptibility of the initial α,β-unsaturated ... -
