The Effect of Some parameters of Electrolysis on Apparent Density of Electrolytic Copper Powder in Galvanostatic Deposition
(Switzerland : Trans Tech Publications Ltd, 2000)
The investigation on some properties of electrochemically deposited copper powders from copper sulphate - sulfuric acid has been performed. Relations between conditions of electrolysis of powder storage, apparent density ...
Electrodeposition and morphology of Ni, Co and Ni–Co alloy powders Part II. Ammonium chloride supporting electrolyte
(Elsevier, 2007)
Polarization characteristics of the processes of Ni and Co powders and Ni-Co alloy powders electrodeposition from ammonium chloride containing supporting electrolyte and their morphologies are investigated as a function ...
Influence of ionic equilibrium in the CuSO(4)-H(2)SO(4)-H(2)O system on the formation of irregular electrodeposits of copper
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The relative concentration of hydrogen ion (H(+)) as a function of sulfuric acid (H(2)SO(4)) concentration (calculated using Pitzer's model) and the electrochemical processes by which irregular copper deposits are formed ...
Mixed tetraoxanes containing the acetone subunit as antimalarials
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Eleven new tetraoxanes possessing cholic acid-derived carrier and isopropylidene moiety were synthesized and were tested in vitro and in vivo. In vitro screening revealed that nine of them were more potent against CQ-resistant ...
Microstructure of LaNiO3 thin films obtained by the spin-on technique from citrate precursors
(Elsevier Sci Ltd, Oxford, 2008)
The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from ...
Antimalarial and antiproliferative evaluation of bis-steroidal tetraoxanes
(Elsevier, 2003)
Several cis and trans bis-steroidal 1,2,4,5-tetraoxanes possessing amide terminus were synthesised and evaluated as antimalarials and antiproliferatives. The compounds exhibited submicromolar antimalarial activity against ...
Adsorption of Pb2+, Cd2+ and Sr2+ ions onto natural and acid-activated sepiolites
(Elsevier, 2007)
The adsorption mechanisms of Pb2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge, pHpzc, is 7.4 ± 0.1 for ...
Freshwater cyanobacterial blooms and primary liver cancer epidemiological studies in Serbia
(Journal of Environmental Science and Health - Part C Environmental Carcinogenesis and Ecotoxicology, 2009)
A large part of Central Serbia experiences continual shortage of sufficient ground water resources. For that reason, more than 20 reservoirs serve as drinking water suppliers. Significant and persistent cyanobacterial ...
Interesting coordination abilities of antiulcer drug famotidine and antimicrobial activity of drug and its cobalt(III) complex
(Elsevier, 2006)
Crystal structure of a novel cobalt(III) complex with antiulcer drug famotidine and ethylenediamine was determined. This is the second structure of a transition metal complex with famotidine resolved by a single crystal ...
Oxygen reduction reaction on spontaneously and potentiodynamically formed Au/TiO2 composite surfaces
(Elsevier, 2007)
From aqueous solutions, gold was deposited on freshly polished titanium surface either by displacement reaction or by potentiodynamic polarization. Both of these procedures resulted in the formation of Au/TiO2 composite ...
