Synthesis and characterization of acid-activated Serbian smectite clays obtained by statistically designed experiments
(Elsevier Science Sa, Lausanne, 2008)
Statistically designed experiments were done to study the recovery of Mg content from natural smectite clays from Serbia by hydrochloric acid leaching. The effects of relevant factors, such as temperature, leaching time, ...
Glassy carbon electrodes: II. Modification by immersion in AgNO 3
(Elsevier, 2001)
The modification of glassy carbon by immersion in AgNO 3 solution was studied by cyclic voltammetry, vacuum techniques (AES and XPS) and STM. The influence of Ag + concentration, time of immersion, the presence of oxygen ...
Electrochemical and capacitive properties of thin-layer carbon black electrodes
(Journal of Power Sources, 2008)
Electrochemical properties and porous-structure-dependent capacitive ability of commercial carbon blacks, Black Pearls 2000® (BP) and Vulcan® XC 72R (XC), were investigated in H2SO4 solution by cyclic voltammetry (CV) and ...
Open circuit potentials of metallic chromium and austenitic 304 stainless steel in aqueous sulphuric acid solution and the influence of chloride ions on them
(Corrosion Science, 2008)
Open circuit potential measurements and cyclic voltammetry of chromium and 304 stainless steel in deaerated aqueous H2SO4 solution of pH 1, without and containing NaCl in the concentration range 1-4 M revealed that chromium ...
Influence of manganese oxide on the activity of Pt/Al2O3 catalyst for CO and n-hexane oxidation
(Elsevier, 2006)
The influence of low loadings of MnOx on the catalytic activity for n-hexene and CO oxidation over highly dispersed Pt on alumina catalysts has been investigated. The applied deposition-precipitation method allows Mn to ...
Differentiation of the contribution of local resuspension from that of regional and remote sources on trace elements content in the atmospheric aerosol in the Mediterranean area
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
For the determination of effects of contaminated crude soil on the content of trace elements in the atmospheric aerosol, trace elements in crude soil samples from within the area of influence of local resuspension were ...
LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
(Elsevier, 2008)
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
Pyrolysis and Pt(IV)- and Ru(III)-ion catalyzed pyrolysis of asphaltenes in organic geochemical investigation of a biodegraded crude oil (Gaj, Serbia)
(Elsevier Sci Ltd, Oxford, 2009)
This paper is aimed at investigating the origin and geological history of the biodegraded Gaj (Serbia) crude oil, based on comparison of biomarkers, particularly alkylaromatics, in crude oil maltene fraction, with those ...
Influence of mechanical activation on the structure of ultrafine BaTiO3 powders
(Elsevier, 2009)
The influence of mechanical activation in a planetary ball mill on the change of the structure of BaTiO3 powders has been investigated. The particle size distribution of the nonactivated and activated samples was measured ...
Wall-to-bed heat transfer in vertical hydraulic transport and in particulate fluidized beds
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Wall-to-bed heat transfer in hydraulic transport and in particulate fluidized beds of spherical particles was studied. Experiments were performed by spherical glass particles of 0.80-2.98 mm in diameter with water in a ...
