Improving dispersion of SnO2 nanoparticles in Ag-SnO2 electrical contact materials using template method
(Elsevier, 2013)
Considering that improvement in the performance of Ag-SnO2 electrical contact materials can be realized by an increase in metal oxide dispersion, the influence of SnO2 nanoparticles and method of their introduction in ...
Structural characterization and electrical properties of sintered magnesium-titanate ceramics
(Elsevier, 2013)
In this article the influence of ball miling process on structure of MgO-TiO2 system, as well as the electrical properties of samples after sintering, was investigated. The mixtures of MgO-TiO2 powders were mechanically ...
Mass transfer and fluid flow visualization for single cylinder by the adsorption method
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Mass transfer coefficient in single phase flow around short cylinder, has been studied experimentally using adsorption method. Experiments were conducted in "two-dimensional" column 140 x 10 x 200 mm. The mass transfer ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO center dot ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Chemical Composition of Two Different Extracts of Berries Harvested in Serbia
(American Chemical Society (ACS), 2013)
Total phenolic content (TPC), total anthocyanin content (TAC), free and total ellagic acid content, sugars, minerals, and radical scavenging activity were determined in nine berries harvested in Serbia. More than 30 phenolic ...
Bacillus amyloliquefaciens laccase - From soil bacteria to recombinant enzyme for wastewater decolorization
(Elsevier Sci Ltd, Oxford, 2013)
One hundred wild type strains of Bacillus sp. were isolated from industrial and agricultural soil across Serbia and screened for laccase activity. Three strains showed high laccase activity temperature optimum of 65 and ...
Electrochemical versus Spectrophotometric Assessment of Antioxidant Activity of Hop (Humulus lupulus L.) Products and Individual Compounds
(American Chemical Society (ACS), 2013)
Antioxidant (AO) activity of extracts of hop cones (Serbian domestic varieties) and commercial hop products (Saaz, Spalter, Spalter select, and Magnum pellets) was determined by parallel application of recently developed ...
Role of Spin State and Ligand Charge in Coordination Patterns in Complexes of 2,6-Diacetylpyridinebis(semioxamazide) with 3d-Block Metal Ions: A Density Functional Theory Study
(American Chemical Society (ACS), 2013)
We report here a systematic computational study on the effect of the spin state and ligand charge on coordination preferences for a number of 3d-block metal complexes with the 2,6-diacetylpyridinebis(semioxamazide) ligand ...
