to improve the corrosion protection of copper metal, 0.01m concentration of 1h-1,2,4-triazole-3-thiol (tat) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (gptms) and tetraethoxysilane (teos). it was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. the tat-doped hybrid sol-gel coating was applied over the coppe...

Polyelectrolyte complexes (PECs) are attractive materials for drug delivery application as they offer simple preparations and high drug-loading efficiency. In this study, a novel method preparing polyelectrolyte complex nanoparticles using s

Abstract In the current study, bioethanol has been purified and separated from culture broth using in situ modified bacterial cellulose (BC) membrane with AMPS. To our knowledge, this is first report for development of BC composite separation production media. The characterization prepared was investigated morphology functional groups via scanning electron microscopy (SEM), Fourier transform in...

cross-linked polymeric organogels have attracted much attention in recent years. most synthesized organogels are based on low molecular weight or denderitic materials. the study focuses on the preparation of an alcohol absorbent organogel based on 2-acrylamido-2-methylpropane sulphonic acid (amps) through cross-linking polymerization. polyethylene glycol diacrylate-400 and ammonium persulphate ...
