Correlation of liquid-liquid equilibria of non-ideal binary systems using the non-random, two-liquid model / Korelisanje ravnoteže tečno-tečno neidealnih binarnih sistema pomoću NRTL modela
(Serbian Chemical Society, Belgrade, 2013)
The non-random, two-liquid (NRTL) model with three different forms of temperature dependant parameters was used to correlate the liquidliquid equilibrium data for systems of alcohols with alkanes, and alcohols with two ...
The influence of substituted aromatic aldehydes on the electrodeposition of Zn-Mn alloy / Uloga supstituisanih aromatičnih aldehida u elektrohemijskom taloženju Zn-Mn legura
(Serbian Chemical Society, Belgrade, 2013)
Additives are necessary in the electrodeposition of Zn-Mn alloys at high current densities, in order to reduce the hydrogen evolution reaction and prevent dendrite formation. The influences of two aromatic aldehydes, ...
Azo-hydrazone tautomerism of arylazo pyridone dyes / Azo-hidrazon tautomerija arilazo piridonskih boja
(Association of Chemical Engineers of Serbia, 2013)
In the last three or four decades disperse dyes derived from pyridones (in particular azo pyridone dyes) have gained in importance, and are widely used in various fields. These compounds have excellent coloration properties, ...
The thermal degradation of some polymeric di-alkyl esters of itaconic acid / Termička razgradnja nekih polimernih dialkil estara itakonske kiseline
(Serbian Chemical Society, Belgrade, 2013)
One group of polymers that may help relieve the dependence on crude oil is based on itaconic acid, the biotechnological production of which has become feasible. Itaconic acid and its derivatives can easily be incurporated ...
The influence of the size and surface modification of TIO2 nanoparticles on the rheological properties of alkyd resin / Uticaj veličine nanočestica TIO2 i njihove površinske modifikacije na reološka svojstva alkidne smole
(Association of Chemical Engineers of Serbia, 2013)
Spherical TiO2 particles of different size were dispersed in alkyd resin based on soybean oil. Four samples of TiO2 particles were used, three commercial and one obtained by acid catalyzed hydrolysis of titanium ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
Synthesis and characterization of thermosensitive hydrogels and the investigation of modifiedrelease of ibuprofen / Sinteza i karakterizacija termoosetljivih hidrogelova i ispitivanje modifikovanog oslobađanja ibuprofena
(Association of Chemical Engineers of Serbia, 2013)
The method of the synthesis of poly(N-isopropylacrylamide-co-2-hydroxypropyl methacrylate) hydrogels obtained by radical polymerization is described. Their characterization was carried out by the determination of the ...
Micro-environmentally restricted hybridoma cell growth within polysaccharide hydrogel microbeads
(IOS Press, Amsterdam, 2013)
The mechanism of micro-environmentally restricted hybridoma cell growth caused by action of local mechanical compression stress generated within various polysaccharide hydrogel matrixes is estimated by comparing the growth ...
3-(Methylamino)propylamine as a templating agent in the synthesis of phosphate-based inorganic polymers / 3-(Metilamino)propilamin kao strukturni agens u sintezi neorganskih polimera na bazi fosfata
(Serbian Chemical Society, Belgrade, 2013)
3-(Methylamino)propylamine (MPA) was studied as a structure-directing agent (template) in the synthesis of open-framework phosphate-based materials. The influence of temperature, mole ratio of reactants, crystallization ...
Possibility of carbon steel eafd solidification/stabilization in concrete
(Editura Stiintifica Fmr, Bucharest, 2013)
Steel scrap recycling is generally performed by direct smelting of scrap in an electric arc furnace, generating about 2% of dust per charge. Electric arc furnace dust (EAFD) is characterized as a hazardous material, due ...
