determination of the optimum conditions for production of chitosan nanoparticles
bioedegradable nanoparticles are intensively investigated for their potential applications in drug delivery systems. being a biocompatible and biodegradable polymer, chitosan holds great promise for use in this area. this investigation was concerned with determination and optimization of the effective parameters involved in the production of chitosan nanoparticles using ionic gelation method. s...
متن کاملOptimized synthesis of O-carboxymethyl-N,N,N-trimethylamino chitosan
We present here the synthesis of a highly O-carboxymethylated chitosan derivative. First, an improvedprotocol for the two-step synthesis of N-trimethyl chitosan (TMC) from chitosan was developed, yield-ing a maximum degree of quaternization (DQ) of up to 46.6%. Successively, the chitosan derivativeO-carboxymethyl-N-trimethyl chitosan (CMTMC) was synthesized from the TMC obtained by applyingan o...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Synthesis and Characterization of Fe3O4 Magnetic Nanoparticles Coated with Carboxymethyl Chitosan Grafted Sodium Methacrylate
N-sodium acrylate-O-carboxymethyl chitosan [CMCH-g-PAA(Na)] bound Fe3O4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. CMCH-g-PAA (Na) was obtained by grafting of sodium polyacrylate on O-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegra...
