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 ...
Magnetic field influence on silicon surface periodic structures obtained by plasma flow action
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
External magnetic field influence on silicon submicron surface periodic structures obtained by the action of nitrogen supersonic quasistationary compression plasma flow (CPF) is studied. CPF is generated by magnetoplasma ...
On the deactivation mechanism of RuO2–TiO2/Ti anodes prepared by the sol–gel procedure
(Elsevier, 2005)
The deactivation process that leads to the end of titanium supported RuO2-TiO2 coating service life, for anodes prepared from RuO2 and TiO2 sols, as well as by the conventional thermal decomposition of RuCl3 and TiCl3, was ...
Sesquiterpene lactones from the aerial parts of Inula oculus-christi
(Elsevier, 2003)
Pulchellin E (1) and gaillardin (2) were isolated from the aerial parts of Inula oculus-christi, along with the flavone hispidulin. The C-13-NMR chemical shifts of 1 and 2 are reported.
Electrochemical deposition of Ni–W alloys from ammonia–citrate electrolyte
(Elsevier, 2003)
Ammonia-citrate electrolyte is one of the solutions that are used in practice for electroplating Ni-W alloys. In this contribution, a systematic effort was made to clarify some controversies about the mechanism of the ...
Different responses of mesenteric artery from normotensive and spontaneously hypertensive rats to nitric oxide and its redox congeners
(Springer, 2007)
The conversion of nitric oxide (NO
) into its congeners nitrosonium (NO ) and nitroxyl (HNO/NO) ions may have important consequences for signal transduction and physiological responses. Manganese-containing superoxide ...
Thin layer of Ni-modified 13X zeolite on glassy carbon support as an electrode material in aqueous solutions
(Maik Nauka/Interperiodica/Springer, New York, 2007)
A new type of an electrode material, zeolite modified by the incorporation of Ni or NiO clusters into its cavities, was synthesized by multiple impregnation of zeolite 13X with a Ni-acetylacetonate solution followed by ...
Morphology and phase composition of Ni-Co alloy powders electrodeposited from ammonium sulfate-boric acid electrolyte
(Materials Science Forum, 2006)
In this paper the morphology of Ni-Co powders electrodeposited from ammonium sulfate-boric acid containing electrolyte is investigated as a function of alloy powder composition. Composition of the electrolyte, i.e. the ...
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 ...
