Effect of parameters of pulsating current (PC) regimes on morphology of electrodeposited copper in hydrogen co-deposition range
(Serbian Chemical Society, Belgrade, 2010)
The most often employed electrolytes for the electrodeposition of copper are those based on aqueous solutions of sulfuric acid (H2SO4) and cupric sulfate (CuSO4). There is an ionic equilibrium of a lot of species in the ...
Oxidation of formic acid on bulk and nanosized Pt-Co alloys
(Serbian Chemical Society, Belgrade, 2010)
Bulk Pt3Co and nanosized Pt3Co and PtCo alloys supported on XC-72 high area carbon were investigated as the electrocatalysts for the oxidation of formic acid. Cyclic voltammetry in 0.1 M HClO4 and stripping voltammetry of ...
Characterization of carbon fibrous materials obtained from tree wastes
(Serbian Chemical Society, Belgrade, 2010)
Carbon fibres can be obtained in rather wide variety of structures, compositions and properties, depending on the nature of the organic precursor and conditions of the process applied in their preparation. In order to get ...
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 ...
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 ...
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 ...
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 ...
Electrodeposition of iron powder particles of different characteristics
(Serbian Chemical Society, Belgrade, 2010)
Iron deposits obtained at high current densities and overpotentials are very important from a technological point of view. It has been stated that the open and porous structures of copper or iron deposits obtained at high ...
The qualitative determination of oseltamivir phosphate in Tamiflu® capsule by cyclic voltammetry with simultaneous HPLC determination
(Serbian Chemical Society, Belgrade, 2010)
A gold electrode was applied in the voltammetric determination of oseltamivir phosphate standard in 0.05 M NaHCO3. Oseltamivir phosphate as a standard and as a component of Tamiflu capsule exhibited the identycal cyclic ...
Photovoltaics of sol-gel processed titanium oxide coating
(Serbian Chemical Society, Belgrade, 2010)
Titanium oxide is applied as a photocatalyst in organic synthesis and for waste water treatment and outdoor air purification. In this work, photoelectrochemical (PEC) activity of titanium oxide coating on titanium substrate, ...
