Adsorption of Xyloglucan onto Cellulose and Cellulase onto Self-assembled Monolayers
… of xyloglucan (XG) onto thin desulfated nanocrystalline cellulose (DNC) films was studied by surface plasmon resonance spectroscopy (SPR), quartz crystal microbalance with dissipation monitoring (QCM-D), and atomic force microscopy (AFM) measurements. These studies were compared to …

Effect of surface modifications on biodegradation of nanocellulose and microbial response
… on in product development. In particular, nanocellulose is touted as a promising green nanomaterial, as it is sourced from an effectively inexhaustible feedstock of wood-based cellulose and is assumed to be harmless to the environment since it is derived from a natural material and assumed to …

Characterization of Cellulose and Chitin Thin Films and Their Interactions with Bio-based Polymers
… the two most abundant natural polymers on earth, cellulose and chitin have attracted increasing attention as a source of renewable energy and functional materials. Thin films of cellulose and chitin are useful for studying interactions of these materials with other natural and synthetic molecules …

Adsorption Studies of Polysaccharides and Phospholipids Onto Cellulose
Interactions between biomolecules and cellulose films at solid/liquid interfaces was studied by surface plasmon resonance spectroscopy (SPR), quartz crystal microbalance with dissipation monitoring (QCM-D) and in situ atomic force microscopy (AFM) measurements. This dissertation shows the porous …

Effect of nano- fillers on tensile properties of biopolymer films
… requirement. In this study, microcrystalline cellulose (MCC), nanocrystalline cellulose (CNC), CaCO3 nanoparticles, hydrophilic nanoclay and hydrophobic nanoclay were separately added as fillers to the polymers, konjac glucomannan (KGM), hydroxypropyl methylcellulose (HPMC), and zein to …

Synthesizing a Heparin Mimic Material Derived from Cellulose Nanocrystals
… induced thrombocytopenia and osteoporosis. Cellulose nanocrystals (CNCs) contain the same 1,4 linked pyranose backbone structure as heparin along with desirable mechanical properties, like high stiffness and anisotropic shape. By altering the functionalization on the surface of CNCs to …

Hydrodynamic interactions of complex fluids and fibrous media
… which consists of an aqueous suspension of nanocrystalline cellulose fibers (length 200nm, aspect ratio 20). The changes in the rheological behavior of these dispersed fibrous systems are investigated as the volume fraction of nanofibers are varied. Finally, the correlative technique of …
