Synthesis and characterization of poly(2-hydroxyethyl methacrylate/itaconic acid/poly(ethylene glycol) dimethacrylate) hydrogels
(Elsevier Science Sa, Lausanne, 2012)
Hydrogels based on 2-hydroxyethyl methacrylate (HEMA), different poly(ethylene glycol) dimethacrylates (PEGDMA) and itaconic acid (IA) were prepared by free radical crosslinking copolymerization. The influence of different ...
Problems and perspectives of agro-industrial sector in Republic of Serbia and measures for overcoming crisis / Problemi i perspektive agroindustrijskog sektora u Republici Srbiji i mere za prevazilaženje krize
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2013)
The paper concludes that the concept for improving export of agro and food products, apart from the stable and sustainable production growth, requires the export structure adjustments in line with the demand requirements ...
The thermal degradation of some polymeric di-alkyl esters of itaconic acid / Termička razgradnja nekih polimernih dialkil estara itakonske kiseline
(Serbian Chemical Society, Belgrade, 2013)
One group of polymers that may help relieve the dependence on crude oil is based on itaconic acid, the biotechnological production of which has become feasible. Itaconic acid and its derivatives can easily be incurporated ...
Kinetics measurements and in situ Raman spectroscopy of formation of hydrogen-tetrabutylammonium bromide semi-hydrates
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The kinetics of formation of H-2-TBAB semi-clathrate hydrates was studied in this work in order to elucidate their potential for H-2 storage. The influence of pressure (5-16 MPa), TBAB concentration (2.6 mol% and 3.7 mol%) ...
Synthesis, structural and biological characterization of 5-phenylhydantoin derivatives as potential anticonvulsant agents
(Springer Wien, Wien, 2012)
Considering the importance of hydantoin derivatives in treatment of status epilepticus, four 5-phenylhydantoins, whose lipophilicities were estimated to be similar to that of phenytoin, were synthesized. Evaluation of their ...
Assessment of the integrity of welded pipes / Procena integriteta zavarenih cevi
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The subject of the paper is analysis of the integrity of welded pipes made of API J55 steel by high frequency contact welding (HF). Experimental research on the mechanical properties of the base material was conducted on ...
Electrochemical impedance spectroscopy investigations on glassy carbon electrodes modified with poly(4-azulen-1-yl-2,6-bis(2-thienyl)pyridine)
(UPB Scientific Bulletin, Series B: Chemistry and Materials Science, 2013)
A characterization of glassy carbon (GC) electrodes modified by controlled potential electrolysis of 4-azulen-1-yl-2,6-bis(2-thienyl)pyridine (L) in acetonitrile solutions containing tetra-n-butylammonium perchlorate is ...
Asymmetric hydrogel membranes for heavy metal adsorption
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Hydrogels containing strong acid groups have been used in the past for the removal of heavy metals. Unfortunately such hydrogels exhibit poor mechanical properties and are generally difficult to handle. In this work we ...
Homogeneous-heterogeneous catalytic effect of CaO · ZnO/K2CO3 during biodiesel synthesis
(Czech Society of Chemical Engineering, 2014)
Environmentally friendly solutions of liquid poly(ethylene glycol) and imidazolium based ionic liquids with bistriflamide and triflate anions: Volumetric and viscosity studies
(Elsevier Science Bv, Amsterdam, 2013)
In this paper, densities and viscosities of the solutions of PEG200 with two imidazolium ionic liquids, 1-ethyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}amide ([C(2)mim][NTf2]) and 1-ethyl-3-methylimidazolium ...
