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 ...
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 ...
Preliminary analysis of fatty acid chemistry of Kindbergia praelonga and Kindbergia stokesii (Brachytheciaceae) / Preliminarna analiza hemije masnih kiselina vrsta Kindbergia praelonga i Kindbergia stokesii (Brachytheciaceae)
(Serbian Chemical Soc, Belgrade, 2010)
Moss species of the family Brachytheciaceae, Kindbergia praelonga (Hedw.) Ochyra and Kindbergia stokesii (Turn.) Ochyra, were preliminarily analysed for their fatty acid composition with the aim of studying the chemical ...
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 ...
Current oscillations during the anodic dissolution of copper in trifluoroacetic acid
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
A phenomenon of current oscillators was characterized crosswise active-passive potential region during the electrodissolution of copper electrode in trifluoroacetic acid (TFA). The current density-potential curves show two ...

Modified bentonite as adsorbent and catalyst for purification of wastewaters containing dyes / Modifikovani bentonit kao adsorbent i katalizator za prečišćavanje otpadnih voda koje sadrže boje
(Assoc Chemists & Chemical Engineers Of Serbia, Belgrade, 2010)
Modification and characterization of bentonite from location Bogovina, Serbia was performed in order to obtain material applicable in wastewater purification. The LT 75μm bentonite fraction was used in organobentonite ...
Biodiesel synthesis using K2CO3/Al-O-Si aerogel catalysts / Sinteza biodizela katalizovana alumosilikatnim aerogelom sa K2Co3
(Serbian Chemical Society, 2010)
In this study, catalysts for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as the active component on an alumina/silica support were synthesized using the sol-gel method, which was followed by drying ...
A study of the catalytic role of a gold electrode in the electrochemical activation of four macrolide antibiotics in sodium bicarbonate solution / Ispitivanje katalitičke uloge elektrode od zlata u elektrohemijskoj aktivaciji četiri makrolidna antibiotika u natrijum-bikarbonatnom elektrolitu
(Association of the Chemical Engineers of Serbia, 2010)
Using the cyclic voltammetry, it has been shown that hydrogen evolution at a gold electrode is necessary in the electrochemical activation of azithromycin dihydrate and erythromycin A. After four hours of the potential ...
