Methanol electrooxidation on supported Pt and Pt/Ru catalysts in alkaline solution / Oksidacija metanola na Pt i Pt/Ru nanokatalizatorima u alkalnoj sredini
(Tehnika - Novi materijali, 2003)
The kinetic of methanol oxidation on 47.5 wt% Pt and 54 wt% Pt/Ru catalysts supported on high surface area carbon are measured in 0.1 M NaOH at 295 K and 333 K. The catalysts used were characterized by using TEM and XRD ...
Comparative electrochemical study of some cobalt(III) and cobalt(II) complexes with azamacrocyles and β-diketonato ligands / Komparativno elektrohemijsko ispitivanje nekih kobalt(III)i kobalt(II) kompleksa sa azamakrocikličnim i β-diketonato ligandima
(Serbian Chemical Society, 2003)
The electrochemical properties of eight mixed-ligand cobalt(III) and co balt(II) complexes of the general formulas [CoIII(Rac)cyclam (ClO4)2 (1)–(4) and [Co2II(Rac)tpmc](ClO4)3 (5)–(8) were studied. The substances were ...
Effect of temperature on the methanol oxidation at supported Pt and PtRu catalysts in alkaline solution
(Elsevier, 2003)
The effect of temperature on the kinetics of methanol oxidation on supported 47.5 wt% Pt, 54 and 33.5 wt% Pt/Ru catalysts was studied in 0.1 M NaOH at 295, 313 and 333 K using thin-film rotating disk electrode (RDE) method. ...
Light modulation utilizing photonic crystal-based photoelastic elements with dual built-in defect
(IEEE Computer Society, 2003)
In this paper we analyze optical modulation by stress-sensitive active elements based on photonic crystals utilizing photoelasticity effects. Our approach is to utilize thin film sensitive elements with photonic bandgap ...
A new class of electromagnetically coupled printed antenna arrays
(IEEE Computer Society, 2003)
A new class of electromagnetically coupled microwave printed antenna arrays using three coplanar strip-TCS (CPW with finite narrow ground strips) is reported. Two versions of this antenna array are introduced. (1) Antenna ...
A new type of slow-wave PBG microstrip ring resonator
(IEEE Computer Society, 2003)
A new type of microstrip ring resonator is introduced. In order to minimized dimensions the ring resonator is constructed like a PBG structure. The central frequency is 50% lower than in the conventional case. Additional ...
Akinetic study of the depyritization of oil shale HCl-kerogen concentrate by Thiobacillus ferrooxidans at different temperatures / Kinetičko proučavanje depiritizacije HCL-kerogenskog koncentrata bituminoznog škriljca pomoću Thiobacillus ferrooxidans na različitim temperaturama
(Serbian Chemical Society, 2003)
The results of kinetic studies of bacterial depyritization of HCl-kerogen concentrate of Aleksinac (Serbia) oil shale by the chemolithoautotrophic thionic bacteria Thiobacillus ferrooxidans under discontinuous laboratory ...
The critical apparent density for the free flow of copper powder / Kritična nasipna masa za tečenje praha bakra
(Serbian Chemical Society, 2003)
A method for the determination of the critical apparent density, which permits the free flow of electrodeposited copper powder is discussed. It was found that powders the apparent density of which were larger than 2.3 g/cm3 ...
Absorption in a three-phase fluidized bed II: Mass transfer investigations / Apsorpcija u koloni sa pokretnim punjenjem II - ispitivanja karakteristika prenosa Mase
(Association of Chemical Engineers of Serbia, 2003)
The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration ...
