(Serbian Chemical Society, Belgrade, 2010)
This paper reports the results of an FT-IR and NIR study of N-methylformamide in carbon tetrachloride solution in presence of ethers as the O-electron donors, i.e., diethyl ether (DEE), diisopropyl ether (DiPE), methyl t- ...
Microwave synthesis and characterization of Pt and Pt-Rh-Sn electrocatalysts for ethanol oxidation / Mikrotalasna sinteza i karakterizacija Pt i Pt-Rh-Sn katalizatora za oksidaciju etanola
(Serbian Chemical Society, Belgrade, 2011)
Carbon-supported Pt and Pt-Rh-Sn catalysts were synthesized by the microwave-polyol method in ethylene glycol solution and were investigated in the ethanol electro-oxidation reaction. The catalysts were characterized in ...
Structure-activity relationships of 3-substituted-5,5-diphenylhydantoins as potential antiproliferative and antimicrobial agents / Uticaj strukture na antiproliferativnu i antibakterijsku aktivnost 3-supstituisanih-5,5-difenilhidantoina
(Serbian Chemical Society, Belgrade, 2011)
A series of twelve 3-substituted-5,5-diphenylhydantoins was synthesized, including some whose anticonvulsant activities have already been reported in the literature. Their antiproliferative activities against HCT-116 human ...
Correlation between the degree of conversion and the elution of leachable components from dental resin-based cements / Korelacija stepena konverzije i količine oslobođenih supstanci iz dentalnih kompozitnih cemenata
(Srpsko hemijsko društvo, Beograd, 2011)
This study examined the possible correlation between the degree of conversion (DC) and the amount of substances eluted from three commercial cured resin-based cements. The DC of the various resin-based cements was measured ...
Crystal growth of K2TiGe3O9 in the glass / Rast kristala K2TiGe3O9 u staklu
(Serbian Chemical Society, Belgrade, 2010)
The kinetics and mechanism of isothermal crystal growth of K2TiGe3O9 from a glass of the same stoichiometric composition were studied. The crystal growth rate, U, in the range 1x10-11-1.27x10-10 m s-1 was experimentally ...
The apparent density as a function of the specific surface of copper powder and the shape of the particle size distribution curve
(Serbian Chemical Society, 2003)
The relation between the specific surface and apparent density of copper powders electrodeposited from acid copper sulphate solutions is established. It is shown that the apparent density is inversly proportional to the ...
Temperature dependence of the Kovats retention indices for alkyl 1, 3-diketones on a DB-5 capillary column / Temperaturna zavisnost kovačevih retencionih indeksa 1,3-diketonan a DB-5 kapilarnoj koloni
(Serbian Chemical Society, Belgrade, 2004)
A series of alkyl 1,3-diketones were used to study the temperature dependence of the Kovats retention indices in the temperature range 130–190 ºC (403–463 K). The temperature dependence is described by the empirical equation ...
