Effect of non-stationary current regimes on the morphology of silver electrodeposits / Efekat nestacionarnih strujnih režima na morfologiju taloga srebra
(Serbian Chemical Society, Belgrade, 2009)
This work is concerned with the use of reverse current regimes in order to form small-grained and compact silver deposits during the electrorefining process. Several parameters were varied, i.e., i) anodic overpotential, ...
Properties of Cu-Al2O3 Powder and Compact Composites of Various Starting Particle Size Obtained by High-Energy Milling
(Savez inženjera metalurgije Srbije, 2009)
Copper-based composites were obtained using high energy milling. The inert gas-atomized prealloyed copper powder (average particle size - 30 μm) containing 2 wt.% Al, and the mixture of electrolytic copper powder (average ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt")/Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
