Lipase production by Yarrowia lipolytica using olive oil processing wastes as substrates / Proizvodnja lipaze iz Yarrowia lipolytica korišćenjem otpadnih sirovina industrije prerade maslina kao supstrata
(Serbian Chemical Society, Belgrade, 2013)
In this study, the solid and liquid wastes from the olive oil processing industry were evaluated as substrates for Yarrowia lipolytica growth with the aim of lipase production. Olive mill wastewater and olive oil cake ...
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). ...
Analytical Model for Drift Region Voltage Drop in 4H-SiC Vertical Double Implanted Metal Oxide Semiconductor Field Effect Transistor: Effect of Anisotropy
(IOP Publishing Ltd, Bristol, 2013)
Silicon carbide (H-4-SiC as well as H-6-SiC) is known to be an anisotropic material. Among others, the transport parameters in the c-direction such as low field mobility and saturation velocity, are moderately different ...
A study of the antibacterial activity and stability of dyed cotton fabrics modified with different forms of silver / Ispitivanje antibakterijske aktivnosti i stabilnosti obojene pamučne tkanine modifikovane različitim formama srebra
(Serbian Chemical Society, Belgrade, 2012)
This study compares the effect of colloidal silver nanoparticles and the commercial RUCO-BAC AGP agent with silver chloride as the active component on the antibacterial activity of dyed cotton fabrics. Cotton fabrics were ...
Generalized point interaction and tunneling times
(World Scientific Publ Co Pte Ltd, Singapore, 2012)
The scattering properties of four-parameter one-dimensional point interactions also define time aspect of these interactions. In this paper we investigate how different families of point interactions affect the relevant ...
Lipophilicity assessment of some 5,5-disubstituted hydantoins by the means of reversed phase liquid chromatography / Procena lipofilnosti nekih 5,5-disupstituisanih hidantoina primenom tečne hromatografije na obrnutim fazama
(Association of the Chemical Engineers of Serbia, 2013)
The retention of some 5,5-disubstituted hydantoins was investigated by reversed phase high performance thin-layer chromatography (RP HPTLC) and reversed phase high-pressure liquid chromatography (RP HPLC). The mobile phases ...
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 ...
Enzymatic synthesis and application of fatty acid ascorbyl esters / Enzimska sinteza i primena askorbil-estara masnih kiselina
(Association of Chemical Engineers of Serbia, 2013)
Fatty acid ascorbyl esters are liposoluble substances that possess good antioxidative properties. These compounds could be synthesized by using various acyl donors for acylation of vitamin C in reaction catalyzed by chemical ...
