Solvatochromism of 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones / Solvatohromizam 5-(4-supstituisanih arilazo)-4-fenil-6-metil-3-cijano-2-piridona
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Eight 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones were synthesized by reaction of benzoylacetone and arendiazonium salt, followed by condensation with cyanoacetamide. Absorption spectra of all azo ...
Keratin-polyethylene oxide bio-nanocomposites reinforced with ultrasonically functionalized graphene
(Royal Society of Chemistry, 2015)
Polyethylene oxide (PEO) functionalized graphene (f-G) was prepared by ultrasonication of pristine graphene in PEO aqueous solution. The feasible sonication protocol of PEO degradation and graphene functionalization enabled ...
Air pollutant emission forecasting in Belgrade using artificial neural networks / Predviđanje emisija odabranih zagađujućih materija vazduha u Beogradu korišćenjem veštačkih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2013)
Intensive industrial development has led to the increase of pollutants in the air, water and land. In order to gain a clear insight into the sources of emissions, many countries have implemented registers of pollutants in ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
Characterization of dextransucrase from Leuconostoc mesenteroides T3, water kefir grains isolate
(Savez hemijskih inženjera, Beograd, 2017)
The production of dextransucrase (DS) by Leuconostoc mesenteroides T3, novel isolate from water kefir grain, was studied and optimized. Bacterial supernatant reached activity of 3.1 U/ml when the culture was grown at 23 ...
A terephthalate-bridged two-dimensional heteronuclear Cu(II)-Mn(II) complex with a terminal 2,2 '-dipyridylamine ligand / Хетеронуклеарни дводимензионални Cu(II)–Mn(II) комплекс са мостовним терефталат-лигандима и терминалним 2,2'-дипиридиламин- лигандом
(Srpsko hemijsko društvo, 2017)
A terephthalate-bridged heteronuclear Cu(II)-Mn(II) complex [Cu2Mn(dipya)(2)(tpht)(3)](n), I, where dipya is 2,2'-dipyridylamine and tpht is the anion of 1,4-benzenedicarboxylic (terephthalic, H(2)tpht) acid was synthesized ...
Conformational stability of 5-substituted orotic acid derivatives analyzed by measuring C-13 NMR chemical shifts and applying linear free energy relationships
(Elsevier, Amsterdam, 2019)
Conformational stability of various 5-substituted orotic acid derivatives was studied by applying linear free energy relationships (LFER) to the C-13 NMR chemical shifts. The correlation analysis for the substituent-induced ...
Plate heat exchanger design software for industrial and educational applications
(Savez hemijskih inženjera, Beograd, 2017)
Plate heat exchanger is a type of heat exchanger that uses corrugated metal plates to transfer heat between two fluids. The plate corrugations are designed to achieve turbulence across the entire heat transfer area thus ...
Synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalysed by amino acids / Sinteza 4,6-dimetil-3-cijano-2-piridona katalizovana aminokiselinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In this work the synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalyzed by amino acids was studied. In the first part of the work, the optimization was carried out by varying the initial concentration of glycine, the molar ...
Electrochemical oxidation of methanol on Pt/(RuxSn1-x)O2 nanocatalyst / Elektrohemijska oksidacija metanola na katalizatoru Pt/(RuxSn1-x)O2
(Serbian Chemical Society, Belgrade, 2013)
Ru-doped SnO2 powder, (RuxSn1-x)O2, with a Sn:Ru atomic ratio of 9:1 was synthesized and used as a support for Pt nanoparticles (30 mass % loading). The (RuxSn1-x)O2 support and the Pt/(RuxSn1-x)O2 catalyst were characterized ...
