Microstructural properties of particle-reinforced polytetrafluoroethylene composite bearings after wear
(Springer New York LLC, 2015)High-performance engineering polymers that ensure the desired properties of journal bearings and give good wear results are investigated. We determine the microstructural properties of polymer-based particle-reinforced ... -
Electrical conductivity and spectroscopic characterization of Blends of poly(2-chloroaniline)/polyaniline P(2ClANI)/PANI copolymer with PVC exposed to gamma-rays
(2014)Poly(2-chloroaniline)/polyaniline P(2ClANI)/PANI) random copolymer was synthesized in the form of nanoparticles by chemical routes. Incorporation of P(2ClANI) into PANI backbone significantly increased the solubility of ... -
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
(Kluwer Academic Publishers, 2014)This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ... -
Atom-economical synthesis of complex heterocycles with N-O moiety
(Wiley Blackwell, 2015)A concise and facile method for the synthesis of heterocyclic compounds with N-O tether was introduced. The two important steps of the synthesis are a Mitsunobu reaction and C-H activation. The Mitsunobu protocol allows ... -
Fabrication and characterization of gold-nanoparticles/chitosan film: A scaffold for L929-fibroblasts
(2013)The objective of the present study was to fabricate a gold nanoparticle crosslinked chitosan (Ch/AuNPs) composite film simple and to evaluate its use as a carrier matrix for L929- fibroblasts. L929- fibroblasts were seeded ... -
Fibrous polymer-grafted chitosan/clay composite beads as a carrier for immobilization of papain and its usability for mercury elimination
(Springer Verlag, 2016)Papain, which is an industrially important enzyme, has been immobilized on fibrous polymer-modified composite beads, namely poly(methacrylic acid)-grafted chitosan/clay. Characterization studies have been done using FTIR ... -
Synthesis and Characterization of Chitosan/Polyvinylpyrrolidone/Zeolite Composite by Solution Blending Method
