Preparation and Properties of Sodium Carboxymethyl Cellulose/Sodium Alginate/Chitosan Composite Film

preparation and study of physical properties of starch-cmc biodegradable composite film containing montmorillonite nanoparticles

novel citric acid modified starch-carboxy methyl cellulose (cmc) -montmorillonite (mmt) bionanocomposite films were prepared by casting method and the effect of mmt on the structural and physical properties of the starch-cmc biocomposites was studied. x-ray diffraction test showed thatstrong polar interactions between the hydroxyl groups present in the starch and cmc chains and in the silicate ...

Preparation of ZnO-Polystyerne Composite Films and Investigation of Antibacterial Properties of ZnO-Polystyerne Composite Films

Preparation, structure, and properties of cellulose nanofibril/silk sericin composite film

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Evaluation of Physico-Mechanical and Antimicrobial Properties of Gelatin- Carboxymethyl Cellulose Film Containing Essential Oil of Bane (Pistacia atlantica)

Background and Objectives: Microbial activity is the main factor in spoiling food products, which not only changes their texture and taste but also causes economic damage and poisoning. The present study aimed to assess the effects of essential oil of Bane (Pistacia atlantica) on physico-mechanical and antimicrobial properties of gelatin- carboxymethyl cellulose film. Materials and Methods: ...
