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 ...
Wall-to-liquid mass transfer in fluidized beds and vertical transport of inert particles / Prenos mase zid-fluid u fluidizovanim slojevima i pri vertikalnom transportu inertnih čestica
(Serbian Chemical Society, Belgrade, 2007)
Mass transfer coefficients in single phase flow, liquid fluidized beds and vertical hydraulic transport of spherical inert particles were studied experimentally using 40 mm and 25.4 mm diameter columns. The mass transfer ...
Surface characterization of silver and palladium modified glassy carbon
(Indian Acad Sciences, Bangalore, 2007)
In this work, the influence of silver and palladium on the surface of undoped, boron doped and phosphorus doped glassy carbon has been studied. The silver and palladium concentrations in solution, after metal deposition, ...
Investigation of the reactivity of 4-pyrimidinecarboxylic, 6-hydroxy-4-pyrimidinecarboxylic and 5-hydroxyorotic acids with diazodiphenylmethane in various alcohols: Part III / Ispitivanje reaktivnosti 4-pirimidinkarboksilne, 6-hidroksi-4-pirimidinkarboksilne i 5-hidroksiorotinske kiseline sa diazodifenilmetanom u različitim alkoholima
(Serbian Chemical Society, Belgrade, 2007)
Rate constants for the reaction of diazodiphenylmethane (DDM) with 4-pyrimidinecarboxylic, 6-hydroxy-4-pyrimidinecarboxylic and 5-hydroxyorotic acids were determined in twelve protic solvents at 30 °C using the well known ...
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 ...
Decomposition of methomyl over supported iron catalysts
(Springer, Dordrecht, 2007)
Catalytic wet peroxide oxidation of methomyl over Fe-ZSM-5 and AlFe-pillared montmorillonite was carried out at room temperature, in a glass batch reactor, under constant airflow and halogen lamp light. Both catalysts have ...

The rate constants for the reaction of twenty-two N-(substituted phenylmethylene)- m- and -p-aminobenzoic acids with diazodiphenylmethane were determined in absolute ethanol at 30 °C. The effects of substituents on the ...
Theoretical assessment of calcium arsenates stability:Application in the treatment of arsenic contaminated waste
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca-5(AsO4)(3)OH have been proposed. These immobilization techniques ...
Levels of PAHs in the soils of Belgrade and its environs
(Springer, Dordrecht, 2007)
Polycyclic aromatic hydrocarbons (PAHs) were analysed in 39 soil samples (0-10 cm upper layer) collected in Belgrade, the capital of Serbia. The sampling sites were randomly selected from urban, urban/recreational and rural ...
