This study aimed to improve the surface properties of lignocellulosic cellulose fiber using oxidative grafting method. Various acrylic monomers were used, including methyl methacrylate, acrylate, ethyl and varying monomer concentrations. In addition, effect ceric ammonium nitrate (CAN) as an initiator on efficiency modification was investigated. The experimental results showed that kind concent...

A double hydrophilic ABC triblock copolymer, poly(2-(diethylamino)ethyl methacrylate)-b-poly(2-(dimethylamino)ethyl methacrylate)-b-poly(N-isopropylacrylamide) (PDEA-b-PDMA-b-PNIPAM), containing the well-known pH-responsive PDEA block and thermoresponsive PNIPAM block, was synthesized by atom transfer radical polymerization via sequential monomer addition using ethyl 2-chloropropionate as the i...

Two novel optical power limiters, 2-[ethyl-(4-phenylazo-phenyl)-amino]-ethanol (E4PA) and 2-[ethyl-(4-trifluoromethyl-phenylazo-phenyl)-amino]-ethanol (E4TPA) were synthesized using a diazotization reaction. The purified azo material was made into thin films in a poly(methyl methacrylate) matrix using a gravity settling technique. The electronic nonlinearities of these films were investigated u...

Reline of ill-fitting complete and removable partial dentures enhances their stability and retention by improving the adaptation between the denture intaglio surface and denture-bearing mucosa1). In clinical situations, that reline procedure is usually performed using a direct (chair-side reline system) rather than indirect (laboratory-processed reline system) method, because the former is more...

Fluorinated copolymers with perfluoroalkyl side chains have widespread use in applications requiring superior technology due to their unique surface properties. Kinetic analysis of copolymerization fluorinated acrylates conventional is necessary synthesize such efficiently. However, kinetic investigation reactions are limited the literature experimental difficulties. In this study, methyl metha...
