Hydrogen Evolution on Zeolite Supported Platinum Clusters
(Wiley-VCH, 2003)
NaX type zeolite was loaded with platinum, by the thermal decomposition of Pt(II) acetylacetonate, up to the Pt/NaX mass ratio 0.174. The sample, dispersed on a glassy carbon rotating disc, was used in slightly acidic ...
Corrosion of chromium white cast iron in acidic medium / Korozija visokohromnog belog gvožđa u kiseloj sredini
(Belgrade, Serbia : Engineering Society for Corrosion, 2008)
In this work we studied the electrochemical behavior of chromium white cast irons in deaerated aqueous sulphuric acid solutions of the pH 1-3. The measurements of concentrations of dissolved iron and chromium in the solution, ...
Drying of suspension and pastes in fluidized bed of inert particles / Sušenje suspenzija i pasta u fluidizovanom sloju inertnog materijala
(Serbian Chemical Society, 2000)
A fluid bed dryer with inert particles was used for the drying of suspensions and pastes. The effects of the operating conditions on the dryer throughput and on the product quality were investigated. Experiments were ...
Vacuum Fluctuations in Optical Metamaterials Containing Nonlinear Dielectrics
(Polish Academy of Sciences, 2009)
We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. ...
The effects of a magnetic field on the morphologies of nickel and copper deposits: The concept of 'effective overpotential' / Uticaj primenjenih magnetnih polja na morfologije taloga nikla i bakra - koncept 'efektivne prenapetosti'
(Serbian Chemical Society, 2007)
The morphologies of nickel and copper deposits obtained without applied magnetic fields, and with both parallel and perpendicular applied magnetic fields were examined by the scanning electron microscopy (SEM) technique. ...
Electroreduction of cefetamet on mercury, platinum and gold electrodes / Elektroredukcija cefetameta na elektrodama od žive, platine i zlata
(Serbian Chemical Society, 2000)
The electroreduction of cefetamet (CEF) using gold and platinum electrodes has been investigated in slightly alkaline medium (pH 8.40) where adsorption, previously observed at mercury electrode, was pronounced. This ...
Strukturne karakteristike galvanskih prevlaka bakra / Structural characteristics of electrodeposited copper coatings
(Bosnia and Herzegovina : University of East Sarajevo, Faculty of Technology, 2009)
Uzorci bakra su podvrgnuti mehaničkom i elektrohemijskom glačanju u odgovarajućim elektrolitima za elektrohemijsko glačanje. Na tako prethodno pripremljene površine supstrata izvršeno je taloţenje prevlaka bakra iz dva ...
Evidence of stability of sedimentary organic matter during bacterial desilicification of an oil shale / Dokaz o postojanosti sedimentne organske supstance pri bakterijskoj desilicifikaciji jednog uzorka bituminoznog škriljca
(Serbian Chemical Society, 2001)
Aleksinac oil shale organic matter appeared to remain unchanged, according to elemental, IR, P-GC and P-GC-MS analytical characterization, after exposure to Bacillus circulans-Jordan desilicification for 30 days. These ...
Surface roughness minimum: Ag thin layer deposited on a glass / Minimum površinske hrapavosti: tanki sloj Ag deponovan na staklu
(Belgrade : Serbian Chemical Society, 2001)
In this paper the results of an examination of the surface roughness and morphology dependence of silver thin films up to 100 nm thick deposited on a microscope glass on the deposition rate and on the deposition time are ...
Ethyl 3-(6-phenyl-44-1,2-dithiolo[1,5-b][1,2,4]dithiazol-2-yl) propanoate
(International Union of Crystallography, 2008)
The title compound, C15H15NO2S3, exists in a bicyclic form, with resonance contributions from two monocyclic forms, each without a second S - S bond. The trithiapentalene heterocyclic ring system is planar, with a mean ...
