Photothermal elastic vibration spectra of SiO2 film on Si
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
The silicon-dioxide film on the silicon substrate (SiO2/Si) samples were investigated by the photothermal elastic vibration method. The photothermal elastic vibrations in two-layer rectangular plates were optically excited ...
Effects of UPD adlayer of foreign metals on the oxidation of ethanol on carbon supported Pt-based catalysts
(Serbian Chemical Society, Belgrade, 2010)
Oxidation of ethanol was studied at SnUPD, RuUPD and RhUPD modified and unmodified Pt/C, Pt3Sn/C and Pt3Ru2/C catalysts. All unmodified catalysts were characterized by XRD. Potentiodynamic and chronoamperometric measurements ...
Non-linear frequency response analysis of the kinetics of electrochemical reactions: a case study – ferrocyanide oxidation kinetics
(Serbian Chemical Society, Belgrade, 2010)
In general, electrochemical (EC) systems are non-linear, which means they respond nonlinearly to a frequency-dependent periodic input perturbation of high amplitude imposed around a steady-state. In addition, the kinetics ...
Electrochemical characterization of polyaniline electrode for use in electrochemical power sources
(Nice : International Society of Electrochemistry, 2010)
Polyaniline (PANI) electrode was formed by electrochemical synthesis on graphite under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl and 0.25 mol dm-3 aniline. ...
Ethanol oxidation at Pt-based alloys and UPD modified Pt/C catalysts
(Serbian Chemical Society, Belgrade, 2010)
Activity of two alloys, Pt3Sn/C and Pt3Ru2/C, was compared with the activity of Pt/C modified with corresponding amounts of SnUPD (~25 %) and RuUPD (~40 %) in overall oxidation of ethanol. Pt3Sn/C, Pt3Ru2/C and Pt/C catalysts ...
The electrochemical synthesis of different Ag/PVP nanocomposites
(Serbian Chemical Society, Belgrade, 2010)
The potential use of Ag/poly(N-vinyl-2-pyrrolidone) (PVP) nanocomposites is in wound dressings or soft tissue implants, where Ag nanoparticles (AgNPs) serve as the antimicrobial agent. Ag/PVP nanocomposites were electrochemically ...
The study of the iron phosphate coatings porosity in bufered borate solution
(Serbian Chemical Society, Belgrade, 2010)
The iron phosphate layers on the low carbon steel surface slows steel corrosion in aggressive environments. The quality of the iron phosphate layer depends on the fraction of the total surface area covered by phosphate ...
Characteristics of polyaniline lead - dioxide power sources
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2010)
Polyaniline (PANI) anode, electrochemically synthesized on graphite electrode from sulfuric acid solution, and electrochemically formed thin film lead dioxide cathode, were investigated for possible applications as electrode ...
Cyclic voltammetry study of electrochemically synthesized Ag/PVP nanocomposite
(Serbian Chemical Society, Belgrade, 2010)
Hydrogel nanocomposites of silver nanoparticles (AgNPs) and crosslinked poly(N-vinyl-2-
pyrrolidone) (PVP) were synthesized in situ by a novel electrochemical method. PVP
hydrogels, crosslinked by gamma-irradiation, were ...
