The effect of the particle shape and structure on the flow ability of electrolytic copper powder II: The experimental verification of the model of the representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha II - eksperimentalna potvrda modela reprezentativne čestice praha
(Serbian Chemical Society, 2003)
An analysis of the effects of the shape, surface structure and size distribution of particles on the flow ability of the copper powder was performed. It is shown that the most important property of the particles of a powder, ...
Electrochemical properties of mixed WC and Pt-black powders / Elektrohemijska svojstva smeše prahova WC i Pt
(Serbian Chemical Society, 2008)
The electrochemical characteristics of a mixture of Pt-black and WC powders and its catalytic activity for methanol and formic acid oxidation were investigated in acid solution. XRD and AFM measurements revealed that the ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder IV: The internal structure of the powder particles / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha IV - unutrašnja struktura čestica praha
(Serbian Chemical Society, 2004)
The structure of powder particleswas analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, ...
Influence of surface morphology on methanol oxidation at a glassy carbon-supported Pt catalyst / Uticaj površinske morfologije na oksidaciju metanola na platinskim katalizatorima sa podlogom od staklastog ugljenika
(Serbian Chemical Society, 2008)
Platinum supported on glassy carbon (GC) was used as a model system for studying the influence of the surface morphology of a Pt catalyst on methanol oxidation in alkaline and acidic solutions. Platinum was deposited by ...
Characterization and carbon monoxide oxidation activity of La1-ySryCr1-xRuxO3 perovskites / Katalitička svojstva La1-ySryCr1-xRuxO3 perovskita u oksidaciji ugljenmonoksida
(Serbian Chemical Society, 2000)
The oxidation of CO over La1-ySryCr1-xRuxO3 perovskite type oxides with y=0.3 and 0 £x £0.100 have been studied. X-ray fluorescence analysis confirmed that content of elements in the bulk corresponds to the established ...
The structure of bright zinc coatings / Struktura sjajnih prevlaka cinka
(Serbian Chemical Society, 2000)
The structures of bright zinc coatings obtained from acid sulfate solutions in the presenceof dextrin/salicylaldehyde mixture were examined. It was shown by the STM technique that the surfaces of bright zinc coatings are ...
The effect of the presence of alcohol in the dispersing phase of oxide sols on the properties of RuO2-TiO2/Ti anodes obtained by the sol-gel procedure / Uticaj prisustva alkohola u disperznoj sredini oksidnih solova ha osobine RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2000)
The effect of the addition of ethanol and 2-propanol to the dispersing phase of TiO2 and RuO2 sols mixture on the morphology and, consequently, on the electrochemical properties of the sol-gel obtained activated titanium ...
