Densities and derived thermodynamic properties for the (n-heptane plus n-octane), (n-heptane plus ethanol) and (n-octane plus ethanol) systems at high pressures
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
This work reports densities for the pure n-heptane, n-octane and ethanol at temperatures from (288.15 to 413.15) K and at pressures up to 60 MPa. The same properties were determined for the binary mixtures n-heptane + ...
Effect of caraway, basil, and oregano extracts and their binary mixtures on fungi in growth medium and on shredded cabbage
(Elsevier Science Bv, Amsterdam, 2014)
this study the effect of individual and binary mixtures of caraway, oregano and basil extracts on the growth of Cladosporium cladosporioides, Aspergillus wentii, Eurotium herbariorum, Penicillium aurantiogriseum and Fusarium ...
Characterization of silver/polystyrene nanocomposites prepared by in situ bulk radical polymerization
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Nanocomposites (NCs) with different content of silver nanoparticles (Ag NPs) embeded in polystyrene (PS) matrix were prepared by in situ bulk radical polymerization. The nearly monodisperse Ag NPs protected with oleylamine ...
Correlation of microstructure with the wear resistance and fracture toughness of white cast iron alloys
(Korean Inst Metals Materials, Seoul, 2013)
The objective of this investigation was to set down (on the basis of the results obtained by the examination of white cast iron alloys with different contents of alloying elements) a correlation between chemical composition ...
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 ...
