As an important part of cultural heritage, paper relics have historical, scientific and humanistic values. However, a large number are suffering from aging, mildew, yellowing, cracks, embrittlement other threats, or even completely damaged. To enhance the strength prolong life relics, novel CMC-acrylate-OVPOSS graft copolymer was synthesized with carboxymethyl cellulose (CMC), methyl methacryla...


 Onggok is an organic waste from tapioca production rich in cellulose but has not been utilized fully for other usages. This study aimed to determine the appropriate temperature and time carboxylation process produce CMC cassava with best characteristics. used a factorial randomized block design. Factor 1 was (40oC, 55oC, 70oC) factor 2 (2 hours, 3.5 5 hours). The observed variable yield,...

The value rheology of drilling mud must be in accordance with the conditions wellbore that do not lead to occurrence problems at time drilling. One efforts improve is by adding Carboxymethyl Cellulose (CMC) which useful for increasing viscosity and binding water. This study aims identify effect on use CMC originating from jackfruit skin rheological properties mud. Jackfruit an underutilized org...

ABSTRACT. Biopolymers are referred to the bio-degradable polymer that is derived from living organisms in nature or synthesized renewable materials but needs polymerization. There consisting of monomeric units bond together through a covalent obtain large molecules. A biopolymeric blend sodium carboxymethyl cellulose/sodium alginate (Na-CMC/SA) film was prepared by casting/solvent evaporation m...

during storage of eggs, unfavorable changes occur due to exertion of co2 and water vapor from through of crust pinholes. one of the practical methods for preventing or reducing these changes is to use biopolymer-based coatings. in this research, five coating solutions based on carboxymethyl cellulose (cmc) and glycerol as plasticizer, oleic acid (1 and 2% v/v) and antimicrobial agents (potassiu...

The increasing demand for short charging time on electric vehicles has motivated realization of fast chargeable lithium-ion batteries (LIBs). However, shortening the LIBs is limited by Li+ intercalation process consisting liquid-phase diffusion, de-solvation, SEI crossing, and solid-phase diffusion. Herein, we propose a new strategy to accelerate de-solvation step through control interaction be...

Abstract Epigallocatechin-3-gallate (EGCG) is a plant-derived flavonoid compound with the ability to promote differentiation of human bone marrow-derived mesenchymal stem cells (MSCs) into osteoblasts. However, effect EGCG on osteogenic umbilical cord-derived (HUMSCs) rarely studied. Therefore, in this study, effects are studied HUMSCs by detecting cell proliferation, alkaline phosphatase (ALP)...

PURPOSE The continual search for new products for soft-tissue augmentation has in recent years led to the introduction of long lasting alternatives to hyaluronic acids and collagen that are composed of other polymers able to improve clinical persistence over time. This is the first report in which sodium carboxymethyl cellulose (CMC) has been chemically treated by the cross-linking process and ...
