Influence of Nitrogen and Air Atmosphere During Thermal Treatment on Micro and Nano Sized Powders and Sintered TiO2 Specimens
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
The influence of air and nitrogen atmosphere during heating on TiO2 nano and micro sized powders as well as sintered polycrystalline specimens was analyzed. Sintering of TiO2 nano and micro powders in air atmosphere was ...
Assessment of Fish Stocks and Elemental Pollution in the Danube, Sava and Kolubara Rivers on the Territory of the City of Belgrade, Serbia
(Bulgarian Academy of Sciences, 2014)
There is a lack of adequate estimates of the fish stocks in the Belgrade city area, Serbia, as well as of the current fishery pressure on fish diversity and of the contamination level of fish meat. These factors obstruct ...
Dielectric and magnetic properties of BaTiO3-NiFe2O4 multiferroic composites
(Elsevier Sci Ltd, Oxford, 2014)
Multiferroic composites with the general formula x BaTiO3-(1-x) NiFe2O4 (x=0.5, 0.7, 0.8) were prepared by mixing chemically obtained nickel ferrite and barium titanate powders. Optimum processing parameters for a reduction ...
Biotic Typology of the Danube River Based on Distribution of Mollusc Fauna as Revealed by the Second Joint Danube Survey (2007)
(Bulgarian Academy of Sciences, 2014)
The aim of this study is to present the distribution of aquatic molluscs along a 2600 km long stretch of the Danube River based on information obtained during the Second Joint Danube Survey (JDS2) in 2007. The collected ...
Improving reactivity of fly ash and properties of ensuing geopolymers through mechanical activation
(Elsevier Sci Ltd, Oxford, 2014)
This paper investigated the effects of mechanical activation of fly ash (FA) from thermal power plants on physical-mechanical properties and structure of geopolymers. FA from different power plants in Serbia was mechanically ...
Contrasting effect of silicon on iron, zinc and manganese status and accumulation of metal-mobilizing compounds in micronutrient-deficient cucumber
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2014)
Although the beneficial role of silicon (Si) in alleviation of abiotic stress is well established, little is known of the relevance of Si nutrition under microelement deficiency. The aim of our work was to investigate the ...
Effect of long-term cyanide exposure on cyanide-sensitive respiration and phosphate metabolism in the fungus phycomyces blakesleeanus
(Srpsko biološko društvo, Beograd, i dr., 2014)
The effects of long-term exposure (5 h) of Phycomyces blakesleeanus mycelium to 5 mM KCN on respiration and phosphate metabolites were tested. Exposure to cyanide, antimycin A and azide lead to a decrease in the activity ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
Biomonitoring and Genetic Analysis of Sturgeons in Serbia: A Contribution to Their Conservation
(Bulgarian Academy of Sciences, 2014)
While the historical sturgeon catch in Serbia encompassed mainly four species (beluga sturgeon - Huso huso, Russian sturgeon - Acipenser gueldenstaedtii, stellate sturgeon - Acipenser stellatus, and sterlet - A. ruthenus) ...
Characterization of the Alkoxide-based Sol-gel Derived La9.33Si6O26 Powder and Ceramic
(Slovensko Kemijsko Drustvo, Ljubljana, 2014)
In this study, we report on the acid-catalysed synthesis of La9.33Si6O26 from lanthanum nitrate or acetate and silicon ethoxide (TEOS) in the ethanol solvent, upon the transition from liquid to amorphous and crystalline ...
