The high temperature treatment of wood is one the alternatives to chemical treatment. During this process, heated higher temperatures than those conventional drying. structure changes due decomposition hemicelluloses, ramification lignin, and crystallization cellulose. becomes less hygroscopic. These improve dimensional stability wood, increase its resistance micro-organisms, darken color, modify hardness. However, also might loose some elasticity. Consequently, heat conditions have be...
The steady-state shear and linear viscoelastic deformations of semidilute suspensions rod-shaped nanocrystalline cellulose (NCC) particles in 1.0% hydroxyethyl carboxymethyl solutions were investigated. Addition NCC at the onset suspension concentration significantly altered rheological properties polymer solutions. low-shear viscosity values polymers increased 20–490 times (depending on molecular weight functional groups) by presence NCC. exhibited yield stresses up to 7.12 Pa....
The X‐ray photoelectron spectroscopy (XPS) study of three heat‐treated North American wood species (jack pine, birch and aspen) was carried out to evaluate chemical modifications occurring on the surface during artificial weathering for different times. results suggest that reduces lignin content (aromatic rings) at wood, consequently, carbohydrates increases. This in surfaces richer cellulose poorer lignin. Heat‐treated become acidic due weathering, acidity increases as time Three possible...
Cellulose nanocrystals (CNCs) continue to gain increasing attention in the materials community as sustainable nanoparticles with unique chemical and mechanical properties. Their nanoscale dimensions, biocompatibility, biodegradability, large surface area, low toxicity make them promising for biomedical applications. Here, we disclose a facile synthesis of poly(2-aminoethylmethacrylate) (poly(AEM)) poly(N-(2-aminoethylmethacrylamide) (poly(AEMA)) CNC brushes via surface-initiated...
The avascular nature of hyaline cartilage results in limited spontaneous self-repair and regenerative capabilities when damaged. Recent advances three-dimensional bioprinting have enabled the precise dispensing cell-laden biomaterials, commonly referred to as 'bioinks', which are emerging promising solutions for tissue regeneration. An effective bioink engineering needs create a micro-environment that promotes cell differentiation supports neocartilage formation. In this study, we introduced...
