Cellulose nanocrystals (CNC) were prepared by formic acid hydrolysis and TEMPO- (2,2,6,6-tetramethyl-piperidine-1-oxyl-) mediated oxidation. The CNCs reinforced into biopolymers chitosan (CHI), alginate (ALG), gelatin (GEL) to obtain “CNC-ALG-GEL” “CNC-CHI-GEL” hydrogels. synthesized hydrogels characterized for physicochemical, thermal, structural characterization using Fourier transform infrar...

In this work, natural-based and biodegradable nanofibers were produced by electrospinning for drug delivery wound dressing applications, using gelatin (Gel), chitosan (CS), cellulose nanocrystals (CNC) natural propolis extract. The polymeric formulations parameters optimized, resulting in the development of Gel/CS with mean diameters 97 nm. CNC successfully introduced into optimized solution vi...

Recent demands for high-performance lightweight materials have brought researchers’ attention to various nanoparticles reinforce polymeric materials. As such, sustainable and stiff cellulose nanocrystals (CNC) become a popular candidate as nano-reinforcements. While CNC can offer great advantages, such high mechanical properties low density, it might agglomerate even in hydrophilic polymers bec...

This study evaluated the influence of cellulose nanocrystals (CNC) content on properties epoxy nanocomposites. The CNC were obtained from microcrystalline by acid hydrolysis. 4.0, 5.5 and 7.0% untreated incorporated into resin. Sonication was used to disperse in thermal stability, glass transition temperature degree conversion reduced as observed Thermogravimetry Differential Scanning Calorimet...

In this study, we report the effect of sizing glass fibres (GFs) with tetramethylpiperidine-1-oxyl (TEMPO)-mediated cellulose nanocrystals (t-CNC) to improve interfacial mechanical performance fibre reinforced polymer composites (GFRP). These nanoparticles are introduced at different concentrations yield a coating t-CNCs which (1) sparsely deposited low concentrations, and (2) uniformly self-as...

We use single molecule imaging methods to study the binding characteristics of carbohydrate-binding modules (CBMs) to cellulose crystals. The CBMs are carbohydrate specific binding proteins, and a functional component of most cellulase enzymes, which in turn hydrolyze cellulose, releasing simple sugars suitable for fermentation to biofuels. The CBM plays the important role of locating the cryst...
