O2 reduction on on ink-type rotating disk electrode using Pt supported on high-area carbons
(Electrochemical Soc Inc, Pennington, 1998)
The kinetics of O2 reduction has been examined on an ink-type electrode made with Pt supported on high-area carbon. Electrocatalysls with 5-40 mass % of Pt on Black Pearls, Vulcan XC-72, and Shawinigan acetylene black ...
Examination of rheological properties of fine particle dispersions as carriers for controlled drug release
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
The rheological characteristics of various systems made by mixing blood, blood serum, and drug carriers, as liposomes, lipid emulsion and polymer latex (model system for nano- particles) are reported as function of shear ...
Electrooxidation of H-2, CO, and H-2/CO mixtures on a well-characterized Pt70Mo30 bulk alloy electrode
(Amer Chemical Soc, Washington, 1998)
The electrochemical oxidation of hydrogen (H-2), carbon monoxide (CO), and their mixtures (500 ppm-2%) on a well-characterized Pt70Mo30 bulk alloy was examined using the rotating disk electrode technique in 0.5 M H2SO4 at ...
Some applications of optical fibres in medicine and disturbances in biomedical area
(5th Congress on Modern Optics, OPTIKA 1998, 1998)
The development of medical equipment, telecommunications and computer's technology provides new possibilities for diagnostic purposes. Usually, it is necessary to use optical image or noise transmission. The application ...
Electrodeposition of silver from nitrate solution: Part II. Mechanism of the effect of phosphate ions
(Springer, Dordrecht, 1998)
The mechanism of compact Ag-film formation by electrolysis from nitrate solution with addition of small amounts of phosphate ions is elucidated. It is shown that the phosphate ions exert their effect by lowering the exchange ...
On the serrated yielding in AlMg6.5 alloy sheet
(Serbian Chemical Society, Belgrade, 1998)
Room temperature tensile tests were performed on AlMg6.5 alloy sheet, with Initial strain rates of 6.7x10(4) s(1), 6.7x10(-3) s(-1) and 6.7x10(-2) s(-1), after imposing 70% cold rolling reductions, and annealing at 320 ...
Corrosion behaviour of epoxy coatings investigated by EIS
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
Epoxy coatings were formed by cathodic electrodeposition of an epoxy resin on steel and on electrochemically modified steel surface by Fe-P alloy using constant voltage method (resin concentration 10 wt.%, temperature 26 ...
