Mechanism of heat-induced gelation for ovalbumin under acidic conditions and the effect of peptides
The mechanism of the heat-induced gelation of ovalbumin (OVA) under acidic conditions and the effect of amphiphilic peptide additives on gelation were investigated using dynamic light scattering (DLS) and smal...

Arabinose substitution effect on xylan rigidity and self-aggregation
Substituted xylans play an important role in the structure and mechanics of the primary cell wall of plants. Arabinoxylans (AX) consist of a xylose backbone substituted with arabinose, while glucuronoarabinoxy...

Open AccessTension wood structure and morphology conducive for better enzymatic digestion
Tension wood is a type of reaction wood in response to bending or leaning stem as a corrective growth process. Tension wood is formed by both natural and man-made processes. Most attractively, tension wood con...

Open AccessDynamics of water bound to crystalline cellulose
Interactions of water with cellulose are of both fundamental and technological importance. Here, we characterize the properties of water associated with cellulose using deuterium labeling, neutron scattering a...

Open AccessModification of the nanostructure of lignocellulose cell walls via a non-enzymatic lignocellulose deconstruction system in brown rot wood-decay fungi
Wood decayed by brown rot fungi and wood treated with the chelator-mediated Fenton (CMF) reaction, either alone or together with a cellulose enzyme cocktail, was analyzed by small angle neutron scattering (SAN...

Informing the improvement of forest products durability using small angle neutron scattering
A better understanding of how wood nanostructure swells with moisture is needed to accelerate the development of forest products with enhanced moisture durability. Despite its suitability to study nanostructur...

Comparison of changes in cellulose ultrastructure during different pretreatments of poplar
One commonly cited factor that contributes to the recalcitrance of biomass is cellulose crystallinity. The present study aims to establish the effect of several pretreatment technologies on cellulose crystall...

Morphological changes in the cellulose and lignin components of biomass occur at different stages during steam pretreatment
Morphological changes to the different components of lignocellulosic biomass were observed as they occurred during steam pretreatment by placing a pressure reaction cell in a neutron beam and collecting time-r...

Structural coarsening of aspen wood by hydrothermal pretreatment monitored by small- and wide-angle scattering of X-rays and neutrons on oriented specimens
Structural changes across multiple length scales associated with hydrothermal pretreatments of biomass were investigated by using small- and wide-angle X-ray and neutron scattering on oriented specimens. Isotr...

Synthesis, characterization, and controlled aggregation of biotemplated polystyrene nanodisks
Cross-linked polystyrene nanodisks were prepared by controlled polymerization of styrene and divinylbenzene in the interior of bicelles, discoidal lipid aggregates. Aggregation behavior of polymer nanodisks wa...
