Substituent and structural effects on the kinetics of the reaction of N-(substituted phenylmethylene)-m- and -p-aminobenzoic acids with diazodiphenylmethane / Efekti supstituenata i strukture na kinetiku reakcije N-(supstituisanih)-m- i -p-aminobenzoevih kiselina sa diazodifenilmetanom
(Serbian Chemical Society, Belgrade, 2007)
The rate constants for the reaction of twenty-two N-(substituted phenylmethylene)- m- and -p-aminobenzoic acids with diazodiphenylmethane were determined in absolute ethanol at 30 °C. The effects of substituents on the ...
Preparation and modification of itaconic anhydride-methyl methacrylate copolymers / Sinteza i modifikacija kopolimera anhidrida itakonske kiseline i metil-metakrilata
(Serbian Chemical Society, Belgrade, 2007)
The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60 °C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios ...
Effect of hydrogels based on 2-hydroxyethyl methacrilate to chemiluminescent activity of rat peritoneal macrophages / Efekat hidrogelova na bazi 2-hidroksietil metakrilata na hemiluminescentnu aktivnost peritonealnih makrofaga pacova
(Savez inženjera i tehničara Srbije, Beograd, 2007)
The aim of this study was to examine the effect of hydrogels different chemical construction and synthesized under different conditions, to oxidative activity of rat peritoneal macrophages. The hydrogels are synthesized ...
Environmental impact of plasma application to textiles
(IOP Publishing Ltd, Bristol, 2007)
Plasma technology is currently implemented in a wide range of industrial processes due to high efficiency, low environmental impact and simplicity. Low-temperature plasma treatment can be an alternative to traditional wet ...
Photocatalytic degradation of synthetic dye under sunlight / Fotodegradacija sintetske boje pomoću sunčeve svetlosti
(Association of Chemical Engineers of Serbia, 2007)
Synthetic dyes are widely used in the textile industry. Dye pollutants from the textile industry are an important source of environmental contamination. The majority of these dyes are toxic, mostly non-biodegradable and ...
Preparation and characterization of penicillin acylase immobilized on sepabeads EC-EP carrier
(Association of the Chemical Engineers of Serbia, 2007)
This paper reports the covalent immobilization of penicillin G acylase from E. coli on Sepabeads EC-EP, an epoxy-activated polymethacrylic carrier, and describes the properties of the immobilized enzyme. Due to its versatility ...
Microstructure and properties of silver based cadmium free electrical contact materials
(University of Belgrade, Technical Faculty, Bor, 2007)
The presented work covers part of experimental results of simultaneous study of microstructure, density, hardness and electrical conductivity of sintered electrical contact materials based of Ag- SnO2 with 8, 10 and 12 ...
Photocatalytic degradation of textile dye C.I. reactive orange 16 in TiO2 water suspension by simulated solar light
(Association of the Chemical Engineers of Serbia, 2007)
The photodegradation of C.I. Reactive Orange 16 (RO16), commonly used as a textile dye, was investigated using TiO2 as a catalyst and the sun lamp. The experiments showed that TiO2 and simulated solar light are necessary ...
