Influence of Fe3+ on Photo catalytic Efficiency of Nanopowder-TiO2 and CeO2 - Comparative Study
(ICT Press, Prague, 2010)
Thyme extract improves blood pressure and oxidative stress in spontaneously hypertensive rats
(Lippincott Williams & Wilkins, Philadelphia, 2010)
Hydrogel based on chitosan, itaconic acid and methacrylic acid as adsorbent of Cd2+ ions from aqueous solution
(Elsevier Science Sa, Lausanne, 2010)
A hydrogel has been synthesized by ionic crosslinking of chitosan (Ch) with itaconic acid (IA), followed by a free radical polymerization and crosslinking of Ch/IA network by adding methacrylic acid and the crosslinker. ...
CdSe/CdS nanoparticles immobilized on pNIPAm-based microspheres
(Royal Soc Chemistry, Cambridge, 2010)
In this work, CdSe/CdS semiconductor ligand-exchanged nanoparticles have been immobilized on poly-(N-isopropylacrylamide) (pNIPAM)-based microspheres. The size and the shrinkage capacity of the spheres can be tuned by the ...
Poly[(N-isopropylacrylamide)-co-(itaconic acid)] hydrogels with poly(ethylene glycol)
(Wiley, Hoboken, 2010)
The aim of the work reported here was to investigate temperature- and pH-sensitive hydrogels of N-isopropylacrylamide (NIPAM) and itaconic acid (IA) and their semi-interpenetrating polymer networks (semi-IPNs) with varying ...
Antimicrobial activity of hybrid hydrogels based on poly(vinylpyrrolidone) containing silver / Antimikrobna aktivnost hibridnih hidrogelova na bazi poli(vinilpirolidona) koji sadrže srebro
(Association of Chemical Engineers of Serbia, 2010)
New hybrid hydrogels were prepared by radical copolymerization of 2-hydroxyethyl methacrylate, itaconic acid, poly(vinylpyrrolidone) and silver salt. FTIR spectroscopy has confirmed binding of silver particles in hydrogels. ...
Nb-doped TiO2 as a support of Pt and Pt-Ru anode catalyst for PEMFCs
(Elsevier Science Sa, Lausanne, 2010)
TiO2 doped by 0.5% Nb was synthesized by the acid-catalyzed sol-gel method. BET surface area was determined to be 72 m(2) g(-1). XRD measurements showed that TiO2 has structure of anatase with similar to 13 nm average ...
Tryptophan-functionalized gold nanoparticles for deep UV imaging of microbial cells
(Elsevier Science Bv, Amsterdam, 2015)
Biocompatible fluorescent nanostructures were prepared by a functionalization of gold nanoparticles with the amino acid tryptophan. The gold-tryptophan bioconjugates were investigated by TEM and HRTEM and various spectroscopy ...
Premazi na bazi cirkona sa primenom u Lost Foam procesu livenja / Zircon-based coating for the applications in Lost Foam casting process
(Savez hemijskih inženjera, Beograd, 2012)
U ovom radu je istraživana mogućnost dobijanja novih vatrostalnih premaza na bazi cirkona koji bi imali primenu u livarstvu. Optimizacija sastava premaza kontrolisana reološkim svojstvima postignuta je primenom različitih ...
Nanostructured intrinsically conducting polymers formed by electrochemical synthesis / Nanostruktuirani elektroprovodni polimeri dobijeni elektrohemijskom sintezom
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Due to unique properties of intrinsically conducting polymers (ICP) such as: electrical conductivity, reversible electrochemistry, optical activity, biocompatibility, environmental and corrosion stability, they still ...
