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) ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
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 ...
Degradation of triketone herbicides, mesotrione and sulcotrione, using advanced oxidation processes
(Elsevier, 2013)
Degradation of two triketone herbicides, mesotrione and sulcotrione, was studied using four different advanced oxidation processes (AOPs): ozonization, dielectric barrier discharge (DBD reactor), photocatalysis and Fenton ...
Extensive feedwater quality control and monitoring concept for preventing chemistry-related failures of boiler tubes in a subcritical thermal power plant
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Prevention and minimizing corrosion processes on steam generating equipment is highly important in the thermal power industry. The maintenance of feedwater quality at a level corresponding to the standards of technological ...
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 ...

Phase diagram of the Al-Cu-Sb ternary system was investigated experimentally by DTA and SEM-EDS methods and theoretically by CALPHAD method. The liquidus projection, invariant equilibria, three vertical sections: Sb-Al0.5Cu0.5, ...
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 ...
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 ...
