Phase equilibria investigation and alloys characterization in Sn-In-Ag system / Ispitivanje fazne ravnoteže i karakterizacija legura u sistemu Sn-In-Ag
(Association of Chemical Engineers of Serbia, 2008)
Lead-free soldering has become very popular in the world recently, especially in electronics, because of high ecological demands in industry. Some of lead-free solder alloys are already used in electronic industry, but ...
Uticaj temperature na elektrohemijsko i anomalno ponašanje hroma i legura hroma u kiselim sredinama / Influence of temperature on elektrochemical and anomalous behaviour of chromium and chromium alloys in acid solutions
(Универзитет у Београду, Технолошко-металуршки факултет, 2008)
Ispitivan je uticaj temperature na elektrohemijsko i hemijsko rastvaranje tri vrste hroma u neutralnim i kiselim rastvorima sulfata, sa i bez dodatka hloridnih jona (krupnozrni liveni hrom, sitnozrni valjani hrom i prevlaka ...
Transformation of a petroleum pollutant during soil bioremediation experiments / Transformacije zagađivača naftnog tipa za vreme eksperimenta bioremedijacije
(Serbian Chemical Society, 2008)
The experiment of ex situ soil bioremediation was performed at the locality of the Oil Refinery in Pančevo (alluvial formation of the Danube River, Serbia) polluted with an oil type pollutant. The experiments of biostimulation, ...
Uticaj morfologije površine platinskih materijala na elektrokatalitičku aktivnost u gorivim spregovima / The influence of the surface morphology of platinum materials on the electrocatalytic activity in fuel cells
(Универзитет у Београду, Технолошко-металуршки факултет, 2008)
U ovom radu ispitivan je uticaj morfologije platinskih materijala na elektrokatalitičku aktivnost za reakcije koje se odigravaju u H2/O2 (PEM) gorivom spregu. Kao platinski materijali su korišćeni monokristali platine i ...
The influence of modification on structural, textural and adsorption properties of bentonite / Uticaj modifikacije na strukturna, teksturalna i adsorpciona svojstva bentonita
(Assoc Chemical Engineers Serbia, Belgrade, 2008)
Natural bentonite clay from the Bogovina locality in Serbia was Na-exchanged and modified using hexadecyll-trimethylammonium bromide as surfactant and organobentonite was obtained. The influence of modifications on the ...
Influence of surface morphology on methanol oxidation at a glassy carbon-supported Pt catalyst / Uticaj površinske morfologije na oksidaciju metanola na platinskim katalizatorima sa podlogom od staklastog ugljenika
(Serbian Chemical Society, 2008)
Platinum supported on glassy carbon (GC) was used as a model system for studying the influence of the surface morphology of a Pt catalyst on methanol oxidation in alkaline and acidic solutions. Platinum was deposited by ...

activity of test compounds. The synthesized compounds showed ...
XPS study of the nickel oxidation state in the reduced (Ag)NiMg/SiO2 vegetable oil hydrogenation catalysts
(Society of Physical Chemists of Serbia, 2008)
Two series of (Ag)NiMg/SiO2 catalysts are synthesized on SiO2 support derived
from two silica sources: diatomite activated at 800oC (Series a; Mg/Ni=0.1 and
SiO2/Ni=1.07) and synthetic water glass (Series b; Mg/Ni=0.1 ...
