Study of gold-platinum and platinum-gold surface modification and its influence on hydrogen evolution and oxygen reduction / Površinska modifikacija platine zlatom i zlata platinom i njen uticaj na reakcije izdvajanja vodonika i redukcije kiseonika
(Serbian Chemical Society, Belgrade, 2005)
Surface modification of the electrodes was conducted from sulfuric acid solutions containing the corresponding metal-chloride complexes using cyclic voltammeter. Comparing the charges of the hydrogen underpotential deposition ...
A new ecologically friendly process for the synthesis of selective flotation reagents
(Association of the Chemical Engineers of Serbia, 2009)
A new ecologically friendly synthesis of N-alkyl-O-ethylthioncarbamates from ethyl dixanthogenates, waste material from the xanthate production plant, and monoalkylamines has been performed in this work. Structure determination ...
Karakterizacija površine netkanog sorpcionog materijala na bazi vune kao sekundarne sirovine / Surface characterization of recycled wool-based nonwoven sorbent
(Savez inženjera i tehničara tekstilaca Srbije, Beograd, 2006)
Praćenje promena morfoloških svojstava površine vlakana nastalih modifikovanjem netkanog sorpcionog materijala na bazi vune kao sekundarne sirovine biopolimerom hitozanom i/ili niskotemperaturnom plazmom je od velike ...
Matrix Microstructure and Its Micro-Analysis of Constituent Phases in As-Cast Fe-Cr-C-V Alloys
(Japan Inst Metals, Sendai, 2009)
The as-cast matrix microstructure in 19 mass%Cr-2.8 mass%C white cast iron with up to 4.7 mass% V additions has been studied. Type and degree of the austenite transformation in the course of cooling after solidification ...
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. PVPhydrogels, crosslinked by gamma-irradiation, were ...
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 ...
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, ...
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 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 ...
Effect of heating rate on precipitation of peak-aged Al-Li (8091) alloy: A quantitative approach
(Savez inženjera metalurgije Srbije, Beograd, 2010)
Samples of Al-Li (8091) alloy were solution treated at 540ºC for 30 min, water-quenched and continuously heated in oil at 0.05 and 0.1ºC/min rates, from room temperature to 190ºC when the peak hardness was achieved. Having ...
