Thermodynamic and structural investigation of the Ag-In-Sb system
(Croatian Metallurgical Society, 2007)
The Ag-In-Sb ternary system presents one of the possible lead-free solder candidates. Therefore, the results of thermodynamic study of the alloys in the Ag-In-Sb alloys, obtained using general solution mode!, are presented ...
Concentrations of Cu, Zn, Cd and Pb in urban soils in parks and green areas of Belgrade / Zagađenje metalima urbanog zemljišta u parkovima i zelenim površinama u Beogradu
(Association of the Chemical Engineers of Serbia, 2006)
Several metals in urban soils of Belgrade were extracted by two methods which respectively give estimates of the available and "quasi total" contents. Soil samples were collected from six parks and three green areas within ...
Experimental design approach regarding kinetics of high pressure leaching processes / Dizajniranje eksperimenata u pogledu na kinetiku luženja pri visokim pritiscima
(Savez inženjera metalurgije Srbije, Beograd, 2003)
Kinetics of high pressure leaching of nickel latente ore "Rudjinci", Serbia was studied in this work. The following parameters: temperature, acid to ore ratio, stirring speed, and time were optimized in order to obtain the ...
Influence of heat input on HAZ hardness distribution after surfacing two Q+T steels / Uticaj pogonske energije zavarivanja na raspodelu tvrdoće u ZUT pri navarivanju čelika za poboljšanje
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2002)
The aim of this work was to determine the influence of welding heat input on hardness distribution after SURFACING of two quench+temper steels. The results indicate that variation of heat input can partially provide required ...
The effect of Y2O3 addition on thermal shock behavior of magnesium aluminate spinel
(International Institute for the Science of Sintering, Beograd, 2009)
The effect of yttria additive on the thermal shock behavior of magnesium aluminate spinel has been investigated. As a starting material we used spinel (MgAl2O4) obtained by the modified glycine nitrate procedure (MGNP). ...
Alkylation of N-substituted 2-phenylacetamides: Benzylation of N-(4-nitrophenyl)-2-phenylacetamide / Alkilovanje N-supstituisanih 2-fenilacetamida - benzilovanje N-(4-nitrofenil)-2-fenilacetamida
(Serbian Chemical Society, Belgrade, 2002)
N-(4-Nitrophenyl)-2-phenylacetamide was alkylated with benzyl chloride in the presence of powdered potassium hydroxide at different temperatures and in various solvents in order to establish the reactivity and orientation ...
Phenomenological modelling tools for orthopaedic tissue engineering

Environmental pollution and importance of monitoring of chemical contaminants in food / Zagađenje životne sredine i značaj monitoringa hemijskih kontaminanata u hrani
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2009)
Food is combination of different chemical components important for nutrition and health. Also, some environmental pollutants as heavy metals or some results of anthropogenic activities as a pesticide could be present in ...
Vapor-liquid equilibria of triglycerides-methanol mixtures and their influence on the biodiesel synthesis under supercritical conditions of methanol / Ravnoteža para-tečnost za sistem trigliceridi-metanol i njen uticaj na kinetiku sinteze biodizela pod uslovima natkritičnog metanola
(Serbian Chemical Society, Belgrade, 2007)
The non-catalytic synthesis of biodiesel (fatty acids methyl esters) from triglycerides and methanol proceeds at elevated pressures above 100 bar and temperatures above 523 K. Kinetic investigations of the system revealed ...
Photoelectrochemical properties of sol-gel obtained titanium oxide / Fotoelektrohemijska svojstva titan-oksida dobijenog sol-gel postupkom
(Serbian Chemical Society, Belgrade, 2008)
The photoelectrochemical properties of a sol-gel prepared titanium oxide coating applied onto a Ti substrate were investigated. The oxide coating was formed from an inorganic sol thermally treated in air at 350°C. The ...
