Trace element distribution in surface soils from a coal burning power production area: A case study from the largest power plant site in Serbia
(Elsevier Science Bv, Amsterdam, 2013)
The content of trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the largest coal-fired power plant in Serbia was determined to assess the contribution of emissions to ...
Behavior of the surviving population of Lactobacillus plantarum 564 upon the application of pulsed electric fields
(Elsevier Sci Ltd, Oxford, 2013)
The behavior of the surviving population of Lactobacillus plantarum 564 growing in MRS broth after pulsed electric field (PEF) treatments of different intensities was monitored by isothermal calorimetry, optical density ...
Spark plasma sintering of ZrC-SiC ceramics with LiYO2 additive
(Elsevier Sci Ltd, Oxford, 2013)
Spark plasma sintering (SPS) of ZrC-SiC composite powders in the presence of LiYO2 sintering additive was studied. The starting powders were obtained by a carbothermal reduction (CTR) of natural mineral zircon (ZrSiO4), ...
Two-step microwave sintering-A promising technique for the processing of nanostructured bioceramics
(Elsevier Science Bv, Amsterdam, 2013)
Two-step microwave sintering was applied in this study to process dense nano-structured bioceramics coupled with improved mechanical properties. The decrease in the average grain size to the nanolevel resulting from ...
Antioxidant properties of the anthocyanin-containing ultrasonic extract from blackberry cultivar "Cacanska Bestrna"
(Elsevier, Amsterdam, 2014)
For the first time, an ultrasound-assisted extraction was used to investigate isolation of anthocyanin-containing extracts from the blackberry cultivar "Cacanska Bestrna" widely grown in Serbia. Sonication time and temperature ...
Kinetics of Heterogeneous Biodiesel Synthesis Using Supported ZnO as Catalyst
(Wiley-VCH Verlag Gmbh, Weinheim, 2014)
A heterogeneous catalyst, ZnO supported on alumina/silica, was synthesized by the sol-gel method. The prepared catalysts were employed for methanolysis of sunflower oil. Effects of various supports as well as calcination ...
Core-shell superparamagnetic iron oxide nanoparticle (SPION) clusters: TEM micrograph analysis, particle design and shape analysis
(Elsevier, 2016)
For the first time, particle shape analysis of silica coated iron oxide (maghemite/magnetite) nanoparticle clusters (core-shell nanostructures) is discussed using computational methods. We analyzed three samples of core-shell ...
Removal of toxic metals from industrial sludge by fixing in brick structure
(Elsevier Sci Ltd, Oxford, 2012)
The aim of this study was to test utilization possibilities of industrial sludge in masonry industry, as well as risk of toxic elements leaching potential. Sludge is generated in a hot-dip galvanizing process after waste ...
Microwave as a pre-treatment of triticale for bioethanol fermentation and utilization of the stillage for lactic acid fermentation
(Elsevier, Amsterdam, 2014)
The aims of this research were to investigate the potential for improvement of bioethanol fermentation by microwave pre-treatment of triticale, as well as the possibility of using triticale stillage (a by-product of ...
Catalysis of hydrogen evolution on different Pd/Au(111) nanostructures in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Hydrogen evolution reaction (HER) was studied on Pd/Au(1 1 1) bimetallic surfaces in alkaline solution. Au(1 1 1) was modified by palladium nanoislands spontaneously deposited using PdSO4 center dot 2H(2)O and PdCl2 salts. ...
