The kinetics and mechanism of methanol oxidation on Pt and PtRu catalysts in alkaline and acid media / Kinetika i mehanizam oksidacije metanola na Pt i PtRu katalizatorima u alkalnoj i kiseloj sredini
(Serbian Chemical Society, 2007)
The kinetic of methanol electrochemical oxidation for a series of platinum and platinum-ruthenium catalysts was investigated. A correlation between the beginning of OHad adsorption and methanol oxidation was demonstrated ...
Effect of temperature on the electrodeposition of disperse copper deposits / Uticaj temperature na elektrohemijsko taloženje disperznih taloga bakra
(Serbian Chemical Society, 2007)
The effect of temperature on the electrodeposition of copper at overpotentials belonging to the plateau of the limiting diffusion current density and higher was examined by the determination of the average current efficiency ...
Properties and efficiency of a Pt/Al2O3 catalyst applied in a solid fuel thermo-accumulating furnace / Osobine i efikasnost Pt/Al2O3 katalizatora u termo-akomulacionoj peći na čvrsto gorivo
(Serbian Chemical Society, 2007)
A prototype of a solid fuel thermo-accumulating furnace has been developed. In order to achieve a higher combustion efficiency, a Pt/Al2O3 catalyst in the form of 3 ± 0.3 mm spheres was applied, which enabled further ...
Characterization and corrosion properties of electrodeposited Ni-W alloys / Karakterizacija i korozione karakteristike elektrohemijski taložene legure Ni-W
(Serbian Chemical Society, 2001)
Ni-W alloys electrodeposited from citrate solution consist of three different phases, which are all present in high W-content alloys: a solid solution of W in a Ni matrix; an intermetallic compound Ni4W, as well as another ...
Spin state relaxation of iron complexes: The case for OPBE and S12g
(Serbian Chemical Soc, Belgrade, 2015)
The structures of nine iron complexes that show a diversity of experimentally observed spin ground states were optimized and analyzed using the Density Functional Theory (DFT). An extensive validation study of the new S12g ...
Stereoselective synthesis of α-hydroxy-β-amino acids: The chiral pool approach / Stereoselektivne sinteze α-hidroksi-β-aminokiselina iz prirodnih hiralnih prekursora
(Serbian Chemical Society, 2004)
A method for the stereoselective homologation of -amino acids into syn-α-hydroxy-β-amino acids is described, based on the conversion of stereoisomeric cyanohydrins into trans-oxazolines. The synthetic potential of the ...
Degradation of anionic surfactants using the reactor based on dielectric barrier discharge
(Serbian Chemical Soc, Belgrade, 2016)
Two anionic surfactants (sodium lauryl sulfate - SDS and sodium dodecylbenzenesulfonate - SDBS) were treated with dielectric barrier discharge. Loss of surfactant activity, decrease in chemical oxygen demand (COD) and total ...
Evidence of stability of sedimentary organic matter during bacterial desilicification of an oil shale / Dokaz o postojanosti sedimentne organske supstance pri bakterijskoj desilicifikaciji jednog uzorka bituminoznog škriljca
(Serbian Chemical Society, 2001)
Aleksinac oil shale organic matter appeared to remain unchanged, according to elemental, IR, P-GC and P-GC-MS analytical characterization, after exposure to Bacillus circulans-Jordan desilicification for 30 days. These ...
Surface roughness minimum: Ag thin layer deposited on a glass / Minimum površinske hrapavosti: tanki sloj Ag deponovan na staklu
(Belgrade : Serbian Chemical Society, 2001)
In this paper the results of an examination of the surface roughness and morphology dependence of silver thin films up to 100 nm thick deposited on a microscope glass on the deposition rate and on the deposition time are ...
Process improvement approach to the acid activation of smectite using factorial and orthogonal central composite design methods / Faktorijalni i ortogonalno centralno kompozitni plan eksperimenta kiselinske aktivacije smektita
(Serbian Chemical Society, 2008)
The purpose of this study was to determine the effective operating parameters and the optimum operating conditions of an acid activation process within the framework of improvement of the process. Full two-level factorial ...
