Preparation of glass-ceramic in Li2O-Al2O3-GeO2-P2O5 system
(University of Novi Sad, 2013)
The results of preparation and structural characterization of glass-ceramics from the system Li2O-Al2O3-GeO2-P2O5 are shown in this paper. The crystallization behaviour of the selected glass was examined under non-isothermal ...
Lipase-Catalyzed Synthesis of Ascorbyl Oleate in Acetone: Optimization of Reaction Conditions and Lipase Reusability
(Japan Oil Chemists Soc, Tokyo, 2013)
Lipase-catalyzed ascorbyl oleate synthesis is eco-friendly and selective way of production of liposoluble biocompatible antioxidants, but still not present on an industrial level due to the high biocatalyst costs. In this ...
Characterization of oxide coatings formed by plasma electrolytic oxidation of aluminum in sodium tungstate / Karakterizacija oksidnih slojeva dobijenih plazma elektrolitičkom oksidacijom aluminijuma u natrijum volframatu
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
This paper presents our recent research on morphology and phase composition of oxide coatings formed by plasma electrolytic oxidation of aluminum in 0.1 M sodium tungstate at constant current density of 15 mA/cm2 and ...
Influence of the matrix type on the temperature responsiveness of a poly-nipaam/chitosan microgel functionalized pes fabric
(Institute of Metals and Technology, 2013)
In this paper, the temperature responsiveness (swelling/de-swelling) of the poly-NiPAAm/chitosan (PNCS) microgel applied to a PBS fabric in combination with two different matrixes, i.e., 1,2,3,4-butanetetracarboxylic acid ...
Evaluation of antioxidative effects of twelve 3-substituted-5,5-diphenylhydantoins on human colon cancer cell line HCT-116
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2013)
Antioxidant effects of twelve 3-substituted-5,5-diphenylhydantoins in concentrations of 0.01, 0.1, 1, 10, and 100 mu M on human colon cancer cell line HCT-116 were determined 24 h after treatment. The concentrations of ...
Rhamnolipid and lipase production by Pseudomonas aeruginosa san-ai: The process comparison analysis by statistical approach / Proizvodnja ramnolipida i lipaze iz Pseudomonas aeruginosa san-ai - optimizacija procesa primenom metode odzivnih površina
(Association of Chemical Engineers of Serbia, 2013)
Pseudomonas aeruginosa has been repeatedly reported as a powerful producer of rhamnolipid biosurfactants as well as hydrolytic enzymes. In this study, the effects of four fermentation factors were evaluated using response ...
Substituent effect on IR, 1H- and 13C-NMR spectral data in N-substituted phenyl)-2-cyanoacetamides: A correlation study / Uticaj supstituenata na IR, 1H- i 13C-NMR spektralne podatke N-(supstituisanih fenil)-2-cijanoacetamida - korelaciona analiza
(Association of the Chemical Engineers of Serbia, 2013)
Linear free energy relationships (LFER) were applied to the IR, 1H- and 13C- -NMR spectral data of N-(substituted phenyl)-2-cyanoacetamides. A variety of substituents were employed for phenyl substitution and fairly good ...
Effect of tungsten carbide in carbon Pt catalyst support on electrochemical oxygen reduction in acid solution / Uticaj prisustva volfram-karbida u ugljeničnom nosaču Pt nanočestica na elektrohemijsku redukciju kiseonika u kiselom rastvoru
(Association of Chemical Engineers of Serbia, 2013)
Tungsten carbide was synthesized by calcination of carbon cryogel with embedded tungsten in a form of metatungstate. This material was used as a support for Pt nanoparticles. XRD pattern of W-C support indicated the presence ...
