Characterization and methanol electrooxidation studies of Pt(111)/Os surfaces prepared by spontaneous deposition
(American Chemical Society (ACS), 2006)
Catalytic activity of the Pt(111)/Os surface toward methanol electrooxidation was optimized by exploring a wide range of Os coverage. Various methods of surface analyses were used, including electroanalytical, STM, and XPS ...
Petroleum Pollutant Degradation by Surface Water Microorganisms
(Springer-Verlag GmbH Germany, 2006)
It is well known that the composition of petroleum or some of its processing products changes in the environment mostly under the influence of microorganisms. A series of experiments was conducted in order to define the ...
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 ...
Decorated Ru/Au(111) and Os/Au(111) surfaces: An in situ STM and electrochemistry study
(Russia : Maik Nauka-Interperiodica Publishing, 2006)
The structure and reactivity of bimetallic electrodes obtained by spontaneous deposition of Ru and Os on Au(111) single-crystal surfaces are studied. In situ electrochemical STM and cyclic voltammetry are used to characterize ...
Morphologies of copper deposits obtained by the electrodeposition at high overpotentials
(Elsevier, 2006)
Morphologies of copper deposits obtained at overpotentials belonging to the plateau of the limiting diffusion current density and at higher
overpotentials were examined by the scanning electron microscopy (SEM) technique. ...
Nanostructural Analysis of Mirror – Bright Zinc Coatings
(MAIK "Nauka /Interperiodica" (Russia), 2006)
The zinc coatings electrode posited from solution containing dextrin/salicyl aldehyde mixture are
examined by the scanning tunneling microscopy (STM). It is shown that mirror brightness of these zinc deposits is associated ...
A QSAR study of acute toxicity of N-substituted fluoroacetamides to rats
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
Acute toxicity in vivo toward rats, of nineteen N-alkyl and N-cycloalkyl fluorocetamides [F-CH2-C(O)-NH-R] was correlated with their structure-dependent properties. Used descriptors are: molecular weights (M-w) and heat ...
Structural effects in electrocatalysis: Formic acid oxidation at model and real Pt catalysts
(Materials Science Forum, 2006)
Formic acid oxidation was studied at low-index Pt single crystals (model systems) as well as at the platinum catalyst supported on high area carbon (real catalyst) in HClO4. The Pt single crystals were characterized by ...
Boron redistribution during SOI wafers thermal oxidation
(Institute of Electrical and Electronics Engineers Inc., 2006)
We fabricated Silicon-On-Insulator (Sol) pressure sensors intended for operation in a wide temperature range. After the thermal oxidation process, the measured sheet resistance of the silicon active layer was higher than ...
The effect of hydrogen codeposition on the morphology of copper electrodeposits. 1. The concept of effective overpotential
(Elsevier, 2006)
The effect of hydrogen codeposition on the morphology of copper electrodeposits was studied. The dependences of the overall current and the volume of evolved hydrogen on the quantity of electricity used were plotted and ...
