BACKGROUND Cassava starch, the economically important agricultural commodity in Thailand, can readily be cast into films. However, the cassava starch film is brittle and weak, leading to inadequate mechanical properties. The properties of starch film can be improved by adding plasticizers and blending with the other biopolymers. RESULTS Cassava starch (5%w/v) based films plasticized with glyc...

In the present work, carboxymethyl cellulose (CMC)–polyvinyl alcohol (PVA)–NH4NO3 with addition of ethylene carbonate (EC) based polymer blend electrolyte (PBE) was explored. The complexes PBE EC revealed that an interaction –OH and –COO? CMC–PVA dissociation H+ from NH4NO3 provides a flexibility pathway for ion hopping. optimum ionic conductivity at room temperature found to be 3.92 × 10?3 S/c...

To improve the dispersion effectiveness of carbon nanotubes (CNTs) in epoxy and adhesion resulted composites on steel substrates, this paper proposed to surface treat CNTs using carboxymethyl cellulose (CMC) epoxy-CNTs composite. The characterizations properties reinforced by CMC treated were then systematically investigated. with three different weight fractions (0.5%, 1%, 2%) CMCs their compo...

Pineapple leaf waste, with its high cellulose content, can serve as alternative starting material for the production of carboxymethyl (CMC). In this study, synthesis conditions CMC from pineapple leaves via use microwave heating were optimized. Box-Behnken design and response surface methodology applied to schedule experiments optimize condition, respectively. Preparation was investigated by va...

In this study, bisphasic calcium phosphate (BCP) and two types of polysaccharide, carboxymethyl cellulose (CMC) and hyaluronic acid (HyA), were used to fabricate composite block bone grafts, and their physical and biological features and performances were compared and evaluated in vitro and in vivo. Specimens of the following were prepared as 6 mm diameter, 2 mm thick discs; BPC mixed with CMC ...

Vi khuẩn và nấm phân giải cellulose càng trở nên quan trọng hơn do có nhiều ứng dụng trong đời sống, đặc biệt hủy chất thải giàu sản xuất hữu cơ. Từ 6 tổ mối thu nhận ở huyện Bình Tân, tỉnh Vĩnh Long đã lập được 28 chủng vi 7 đều khả năng CMC (carboxymethyl cellulose), đó các đạt hiệu quả cao gồm 1BTL6 (61,7%), 3BTT6 (65,8%), 2BTNT5 (61,5%) 1BTNT3 (60,4%). Thêm vào đó, từ rơm tạo đường glucose ...

Silicon nanoparticles based composite electrodes for Li-ion batteries reach high specific capacities and enhance cyclability compared with larger silicon particles. Such are foreseen the next generation (LiB). Playing on binder conductive additives in formulation of Si is a well-known strategy to performance. Aqueous electrode formulations using carboxymethyl cellulose as environmentally friend...

The interest in the development of edible and biodegradable films has increased because it is every day more evident that non-degradable materials are doing much damage to the environment. Blends based on different ratios of plasticized poly(vinyl alcohol) (PVA), carboxymethyl cellulose (CMC) and Tannin compound were prepared by solution casting in the form of thin films. Then the blend films w...

The superoxide dismutase enzyme (SOD) contributes to the physiological equilibrium between pro-oxidants and antioxidants, by destroying the superoxide anion (O2). However, its therapeutic use is limited by its fast clearance from the bloodstream and inactivation by its own reaction product, i.e. hydrogen peroxide. Here is a summary of the main strategies developed to circumvent these limitation...

Cellulase was immobilized onto silica gel surfaces pretreated with (3-aminopropyl) triethoxy-silane (3-APTES), and glutaraldehyde (GA) was used as a cross-linker. A carboxymethyl cellulose sodium salt (CMC) solution was used for activity experiments. Protein assay was performed to determine the mass immobilized and compare with free enzyme. Cellulase was successfully demonstrated to be immobili...
