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 ...
Reflection and structural analyses of mirror-bright metal coatings
(Springer, 2004)
Reflection and structural analyses of different copper and zinc coatings were performed. The copper coatings were electrodeposited from a sulfate solution in the presence of thiourea, as well as in the presence of modified ...
Glassy carbon electrodes: II. Modification by immersion in AgNO 3
(Elsevier, 2001)
The modification of glassy carbon by immersion in AgNO 3 solution was studied by cyclic voltammetry, vacuum techniques (AES and XPS) and STM. The influence of Ag + concentration, time of immersion, the presence of oxygen ...
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 ...
Tuning the topologies of Co(II) and Ni(II) complexes with EDTA, 1,3-PDTA and 1,4-BDTA ligands: Synthesis and spectroscopic data of [Mg(H2O)6][Co(1,4-bdta)] · 3H2O and [Mg(H2O)6][Ni(1,4-bdta)] · 3H2O complexes, and the X-ray structure of their chiral crystals
(Elsevier, 2007)
The hexadentate complexes [Mg(H2O)6][Co(1,4-bdta)] • 3H2O (a) and [Mg(H2O)6][Ni(1,4-bdta)] • 3H2O (b) (where 1,4-bdta represents the 1,4-butanediaminetetraacetate ion) have been synthesized and characterized by electronic ...
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 ...
Kinetics of the Formation of Poly(methyldecylsiloxane) by Hydrosilylation of Poly(methylhydrosiloxane) and 1-Decene
(Switzerland : Trans Tech Publications LTD, 2007)
Poly(methylhydrosiloxane) [PMHS], prepared by siloxane equilibration reaction, was used for the hydrosilylation with 1-decene to obtain poly(methyldecylsiloxane) [PMDS]. Pt(0)-1,3-divinyltetramethyldisiloxane complex was ...
Cholesterol bound to hemoglobin in normal human erythrocytes: a new form of cholesterol in circulation?
(Elsevier, 2004)
Objective: To study lipid fraction that is occasionally observed in red blood cell (RBC) hemolysate (supernatants from which membranes were separated). Study design: Plasma lipid profiles, cholesterol (Ch) and phospholipids ...
Characterization of copper powder particles obtained by electrodeposition as function of different current densities
(Journal of Applied Electrochemistry, 2009)
Technological properties of powders depend on their granulometry and morphology. Very often one method is inadequate for characterization of powder particles. This article studied different methods intended for clear ...
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. ...
