Biopolymer electrolyte based on carboxymethyl cellulose has been prepared by doping with different concentration of oleic acid via solution casting technique. Fourier Transform Infrared spectroscopy was used to study the complexation between the salt and polymer. New peak was observed at 1710, 2850, 2920 cm. X-ray diffraction study reveals the amorphous nature of the biopolymer electrolyte. Imp...
Purpose – To introduce recent research and development of biopolymer deposition for freeform fabrication of three-dimensional tissue scaffolds that is capable of depositing bioactive ingredients. Design/methodology/approach – A multi-nozzle biopolymer deposition system is developed, which is capable of extruding biopolymer solutions and living cells for freeform construction of 3D tissue scaffo...
Cellulose is the most abundant and renewable natural semi-crystalline polysaccharide. This biopolymer an inexhaustible source of fibers (NFs), valuable raw material for production microparticles microcrystalline (MCC) powdered cellulose (PC), as well other micro-products, which are widely used in biomedicine, food additives, plastics, materials. In addition, has a nano-fibrillar architecture th...
Abstract The thermal analysis methods were used for the description of adsorption behaviour selected proteins differing in internal stability (ovalbumin (OVA) and lysozyme (LSZ)). These immobilised on surface activated biocarbon obtained from horsetail herb precursor. values hydrodynamic radius both biopolymer macromolecules solution determined by use viscosimetry method. This parameter is impo...
the high hydrophilic property of biopolymer based plastics is one of the most important defects of them. blending biopolymers with compatible synthetic polymers and using nano particles such as nanoclay as nanofiller are improving methods that have been extensively considered in recent years. carboxymethyl cellulose (cmc) is one of the lowest cost biopolymers that have enormous applications in ...
This study was designed to probe the fabrication of unique silver and gold nano-structures engaging a self-designed chitosan-porous anodic alumina nano-composite as a template. Porous anodic alumina has been manufactured by di-step aluminum anodization in an oxalic acid electrolytic bath. The surface properties of porous anodic alumina were reinforced by chitosan neutralized in sodium hydro...
