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 ...
Production of lipase from Pseudozyma aphidis and determination of the activity and stability of the crude lipase preparation in polar organic solvents / Proizvodnja lipaze iz Pseudozyma aphidis i utvrđivanje aktivnosti i stabilnosti lipaze u polarnim organskim rastvaračima
(Serbian Chemical Society, Belgrade, 2011)
The production of lipase from Pseudozyma aphidis (DSM 70725) was determined in six different media. The highest lipase production was observed in a medium with glucose as the sole carbon source, and yeast extract and sodium ...
Corrosion of an austenite and ferrite stainless steel weld / Korozija zavarenog spoja austenitnog i feritnog nerđajućeg čelika
(Serbian Chemical Society, Belgrade, 2011)
Dissimilar metal connections are prone to frequent failures. These failures are attributed to the difference in the mechanical properties across the weld, the coefficients of thermal expansion of the two types of steels ...
Enzymatic synthesis of a vitamin B6 precursor / Enzimska sinteza prekursora vitamina B6
(Serbian Chemical Society, Belgrade, 2013)
3-Cyano-4-(ethoxymethyl)-6-methyl-2-pyridone, an important precursor in the synthesis of vitamin B6, is obtained in the addition reaction between 2-cyanoacetamide and 1-ethoxy-2,4-pentanedione catalyzed by lipase from ...
Determination of surface coverage of iron-phosphate coatings on steel using the voltammetric anodic dissolution technique / Određivanje pokrivenosti površine čelika gvožđe-fosfatnim prevlakama anodnim rastvaranjem primenom linearne voltametrije
(Serbian Chemical Society, Belgrade, 2013)
In this study, the effect of deposition time and concentration of NaNO2 in the phosphate bath on the surface morphology of iron-phosphate coatings on low carbon steel was investigated using scanning electron microscopy ...
Electrochemical methods for corrosion testing of Ce-based coatings prepared on AA6060 alloy by the dip immersion method / Elektrohemijske metode za ispitivanje korozione stabilnosti prevlaka na bazi cerijuma dobijenih potapanjem na leguri AA6060
(Serbian Chemical Society, Belgrade, 2013)
Dip-immersion is a simple and cost-effective method for the preparation of Ce-based conversion coatings (CeCCs), a promising alternative to toxic chromate coatings, on metal substrates. In this work, CeCCs were prepared ...
The use of a gold electrode for the determination of amphetamine derivatives and application to their analysis in human urine / Određivanje derivata amfetamina i primena u analizi humanog urina na elektrodi od zlata
(Serbian Chemical Society, Belgrade, 2013)
The catalytic abilities of a gold electrode were tested for the quantitative determination of amphetamine (A) and 3,4-methylenedioxy-N-methylamphetamine (MDMA) standards by their oxidation using cyclic voltammetry (CV). ...
Experimental study of the thermodynamic and transport properties of binary mixtures of poly(ethylene glycol) diacrylate and alcohols at different temperatures
(Srpsko hemijsko društvo, Beograd, 2015)
Experimental density rho, refractive index n(D) and viscosity eta data of three binary systems of poly(ethylene glycol) diacrylate (PEGDA) + ethanol, + 1-propanol and + 1-butanol were measured at eight temperatures from ...
Separation and determination of dimethylarsenate in natural waters / Razdvajanje i određivanje dimetilarsenata u prirodnim vodama
(Serbian Chemical Society, Belgrade, 2012)
A simple and efficient method for the separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were ...
Removal of a cationic dye from water by activated pinecones
(Srpsko hemijsko društvo, Beograd, 2012)
Adsorption of a cationic phenothyazine dye, Methylene Blue onto activated carbon prepared from pinecones was investigated. The parameters contact time, dye concentration and pH were varied. The kinetic data were found to ...
