Amphiphilic hydroxyalkyl cellulose derivatives for amorphous solid dispersion prepared by olefin cross-metathesis
(Royal Society of Chemistry, 2016-07-07)Olefin cross-metathesis (CM) has enabled design and synthesis of diverse, amphiphilic cellulose ether derivatives (e.g. of ethyl and methyl cellulose). In this paper, hydroxyalkyl cellulose was selected as a hydrophilic ... -
A Case Study to Determine Drivers and Barriers of Appalachian Forest Products in Central America

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 ... -
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 ... -
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 ... -
Nano@lignocellulose intercalated montmorillonite as adsorbent for effective Mn(II) removal from aqueous solution
(Springer Nature, 2018-07-18)This paper describes the preparation of nano@lignocellulose (nano@LC) and a nano@lignocellulose/montmorillonite (nano@LC/MT) nanocomposite, as well as the capacity of the nano@LC/MT for adsorbing manganese ions from aqueous ... -
Preliminary study of Cell Wall Structure and its Mechanical Properties of C3H and HCT RNAi Transgenic Poplar Sapling
(Springer Nature, 2018-07-12)This research focused on the cell wall structure and its mechanical properties of down-regulated Coumaroyl shikimate 3-hydroxylase (C3H) transgenic poplar and down-regulated hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl ... -
Preparation and evaluation of nanocellulose-gold nanoparticle nanocomposites for SERS applications
(The Royal Society of Chemistry, 2015-06-09)Nanocellulose is of research interest due to its extraordinary optical, thermal, and mechanical properties. The incorporation of guest nanoparticles into nanocellulose substrates enables production of novel nanocomposites ... -
Quantitative Genetic Background of the Host Influences Gut Microbiomes in Chickens
(Nature Publishing Group, 2013-01)Host genotype and gender are among the factors that influence the composition of gut microbiota. We studied the population structure of gut microbiota in two lines of chickens maintained under the same husbandry and dietary ... -
Rheology of transgenic switchgrass reveals practical aspects of biomass processing
(2018-03-01)Abstract Background Mechanical properties of transgenic switchgrass have practical implications for biorefinery technologies. Presented are fundamentals for simple (thermo)mechanical ... -
Skateboards as a Sustainable Recyclable Material
(MDPI, 2018-05-15)The exact number of skateboards manufactured every year is unknown, but it is estimated to be in the millions. Most skateboard decks are made from a high grade of maple (Acer spp.) veneer plywood and typically last only a ...
