The crystal structure of 14-oxo-13,14-seco-5α-cholest-13(18)-en-3β-yl acetate (2), obtained (in addition to the (E)-Δ12-isomer 3) by oxidative fragmentation of the C(13)-C(14) bond of 14α-hydroxy-5α-cholestan-3β-yl acetate ...
Activity of some disiloxanes toward the cation exchange resin-catalyst in the siloxane equilibration reaction / Aктивност дисилоксана према катјонској јоноимењивачкој смоли - катализатору реакције силоксанске еквилибрације
(Belgrade : Serbian Chemical Society, 2000)
The relative activities of four disiloxanes toward the cation exchange resin, which was used as an equilibration catalyst, were determined in such a way that the equilibrium initialy present in an arbitrary chosen equilibrate ...
Electrochemistry of active chromium, part IV: Dissolution of chromium in deaerated sulfuric acid / Elektrohemija aktivnog hroma, deo IV - rastvaranje hroma u deaeriranom vodenom rastvoru sumporne kiseline
(Serbian Chemical Society, 2004)
Chromium dissolution in aqueous sulfuric acid solutions in the pH range 0.5 –3 was studied electrochemically by the potentiostatic or very slow potentiodynamic method, and by the analyses of the Cr ion concentrations in ...

(Serbian Chemical Society, 2008)
Four mixed-ligand cobalt(III) complexes (1-4) of the general formula [Co(Rdtc)cyclam](ClO4)2 and [Co(Rac)cyclam](ClO4)2 (cyclam = 1,4,8,11-tetra- azacyclotetradecane; Rdtc = thiomorpholine-(Timdtc) or 2-methylpiperidine- ...
Kinetic study of methanol oxidation on Pt2Ru3/C catalyst in the alkaline media / Kinetika oksidacije metanola na Pt2Ru3/C katalizatoru u alkalnoj sredini
(Serbian Chemical Society, 2007)
The electrochemical oxidation of methanol in NaOH solution was examined on a thin film Pt2Ru3/C electrode. The XRD pattern revealed that the Pt2Ru3 alloy consisted of a solid solution of Ru in Pt and a small amount of Ru ...
The current efficiency during the cathodic period of reversing current in copper powder deposition and the overall current efficiency / Iskorišćenje struje za vreme katodnog perioda reversne struje pri taloženju bakarnog praha i ukupno iskorišćenje struje
(Serbian Chemical Society, 2003)
The current efficiency during the cathodic period of reversing current in copper powder deposition was determined by measuring the quantity of hydrogen evolved. The diagrams from which the instantaneous and average current ...
