The present study was conducted to develop a nanocomposite film of carboxymethyl cellulose (CMC) reinforced with nanocrystals isolated from microcrystalline (CNCMCC) in the presence bismuth ferrite (BFO)/poly-o-phenylenediamine (PoPD). physicochemical properties, mechanical and thermal stability, its photocatalytic activity towards removal methyl orange (MO) were determined. Results show that i...
drying foodstuffs can have negative effects on quantitative and qualitative characteristics of the products, including porosity and bulk density. therefore, novel technologies can be used to improve these characteristics. in this study, apparent density changes during drying grapes pretreated with ultrasound for 10, 20 and 30 minutes, and carboxymethyl cellulose (cmc) at three concentrations of...
Alum had been used in traditional medicine for treatment of oral lesions in Iran.the main aim of this study was to find out a suitable formulation for the mucoadhesive fprm of alum.in this study some materials such as alum,carboxymethyl cellulose (CMC) and Arabic Gum were used.different bases of gum and CMC were made and titration of alum was performed with suitable vbuffer and the rate of wa...
Saccharum munja biomass is a cheap lignocelluloses which has high carbohydrate content and, if properly pre-treated, could be converted to fermentable sugar. The aim of the study is to isolate cellulose degrading microbes from soil samples collected from different regions and to identify cellulose degrading microbes of fungi. A total of 20 soil samples were collected and processed for isolating...
Achieving oriented and ordered remineralization on the surface of demineralized dental enamel, thereby restoring the satisfactory mechanical properties approaching those of sound enamel, is still a challenge for dentists. To mimic the natural biomineralization approach for enamel remineralization, the biological process of enamel development proteins, such as amelogenin, was simulated in this s...
In this study coatings of kaolin and talc particles were successfully applied on the surface polyamide 12 powder intended for laser sintering (LS). Microscopic observations revealed that using carboxymethyl cellulose (CMC) as modifier fillers led to a better coverage polymer grains with between 6 16% function filler type content. Differential scanning calorimetry measurements showed addition an...
A carboxymethyl cellulose (CMC)/polyethyleneimine (PEI) hybrid hydrogel was successfully prepared under green processing conditions. The CMC and PEI formed a polyelectrolyte complex, the three-dimensional (3D) network structure hardened by chemical crosslinking, resulting in suitable properties. In CMC/PEI hydrogel, surface charge easily switched according to pH change, swelling contraction rev...
In the present paper five wild Pleurotus species namely P. floridanus Singer, P. pulmonarius (Fr.) Quél., P. sapidus Quél., P. cystidiosus O.K.Mill. and P. sajor-caju (Fr.) Sing., collected from different localities of North West India have been studied for the qualitative estimation of cellulose and lignin degradation enzymes through colorimetric assays. On the basis of the results obtained, t...
Superabsorbent polymers (SAPs) are functional macromolecules with high water absorption and retention capacities. Nowadays, carboxymethyl cellulose (CMC) nanofibrils (CMCNFs) widely utilized as absorbent materials to replace petroleum-based SAPs, which lead environmental pollution. However, their water- holding characteristics inferior compared those of SAPs. In this study, we explore the polym...
