Manganese leaching in the FeS2-MnO2-O2-H2O system at high temperature in an autoclave
(Elsevier Science Publishers B.V., 2000)
The paper shows: (a) the results of pyrite oxidation by gaseous oxygen in water suspension at high temperatures in an autoclave and (b) the results of simultaneous leaching of Mn4+ from pyrolusite ore by H2SO4 and FeSO4, ...
Contribution to study of processes on the steel cast-sand mould contact surface during casting
(Elsevier Science B.V., 2000)
The testings involved in this paper were part of a comprehensive research project conducted to find out what complex processes were taking place at metal-mould contact surface. These investigations are of particular ...
Alginatna vlakna programirane biološke aktivnosti / Alginate fibers with programmed biologically activity
(Loznica : Viskoza, 2000)
Alginatna vlakna poseduju niz veoma jedinstvenih svojstava i sa aspekta razvijene površine, hidrofilnosti, biokompatibilnosti i netoksičnosti prevazilaze većinu danas poznatih polimera. U ovom radu, alginatna vlakna su ...
Enumeration of labelled quasi-initially connected digraphs
(Elsevier, 2000)
A new class of connected digraphs is introduced - the class of quasi-initially connected digraphs. They are enumerated in the labelled case. Using the apparatus developed for labelled quasi-initially connected digraphs ...
Kinetic analysis of hydrogen evolution at Ni-Mo alloy electrodes
(Elsevier Science Ltd, 2000)
The hydrogen evolution reaction (HER) on Ni, Mo and MoNi intermetallic compound was investigated with ac impedance and dc polarization measurements in 1.0 mol dm-3 NaOH solution at 25 °C. The rate constants of the forward ...
Experimental study of zinc morphology in alkaline electrolyte at low direct and pulsating overpotentials
(Elsevier Sequoia SA, 2000)
A possible mechanism of the formation of spongy zinc electrodeposits is considered. The confirmation of the proposed semiquantitative mathematical model is performed in zinc electrodeposition onto copper wire from a 0.1 M ...
The influence of the aging time of RuO2 and TiO2 sols on the electrochemical properties and behavior for the chlorine evolution reaction of activated titanium anodes obtained by the sol-gel procedure
(Elsevier, 2000)
The influence of the aging time of RuO2 and TiO2 sols used for the preparation of (40% RuO2+60% TiO2)/Ti anodes by the sol-gel procedure on the electrochemical properties and behavior for the chlorine evolution reaction ...
Growth study of surfactant-mediated relaxed SiGe graded layers for 1.55-μm photodetector applications
(Elsevier Sequoia SA, 2000)
A systematic study of Sb sufactant-mediated relaxed SiGe graded layers has been performed. The results have been compared
with those of relaxed SiGe layers grown at high temperatures, showing that the Sb-mediated SiGe ...
The electro-oxidation of the mixture of formaldehyde and 2-propanol on gold (100) and (111) single crystal planes in alkaline medium / Elektrooksidacija smeše formaldehida i 2-propanola na monokristalima zlata orijentacije (100) i (111) u alkalnoj sredini
(Serbian Chemical Society, 2000)
The effect of formaldehyde on the oxidation of 2-propanol and vice versa on gold single crystal planes (100 and 111) was studied. An activating effect in the reaction of the simultaneous oxidation of 2-propanol and ...
A new current line division concept for the determination of the current distribution in electrochemical cells. Part I. Theoretical background of the corner weakness effect in electroforming / Нов концепт поделе струјних линија за одржавање расподеле струје у електрохемијским ћелијама. Део I.Теоријске основе појаве "Corner weakness" у галванопластици
(Belgrade : Serbian Chemical Society, 2000)
A new approach to the determination of the current distribution in electrochemicalcells, the current line division concept, is introduced. The new concept, based on thebasic equations of electrics and electrochemical ...
