4-chloromethyl styrene (cms) was copolymerized with different monomers such as methyl methacrylate (mma), methyl acrylate (ma), 2-ethylhexyl acrylate (eha) by free radical polymerization method at 70 ±1°c using a,a'-azobis(isobutyronitrile) (aibn) as an initiator. the copolymer compositions were obtained using related 1hnmr spectra and the polydispersity of the copolymers were determined using ...
Introduction: Elastin like protein or ELP is a synthetic biopolymer consisting the pentapeptide repeats of VPGXG (X can be any amino acid except Pro). This protein is the thermal responsive polypeptide that undergoes a reversible phase transition. At a temperature below the transition temperature (Tt), ELP molecules assume an extended conformation and thus are soluble in aqueous solution; but u...
This paper addresses the annealing temperature effect on nanostructure and phase transition of copper oxide thin films, deposited by PVD method on glass substrate (at 110 nm thickness) and post annealed at different temperatures (200-400°C) with a flow of 1 cm3s-1 Oxygen. The X-ray diffraction (XRD) was employed for crystallographic and phase analyses, while atomic force m...
