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 ...
Assembly Processes under Severe Abiotic Filtering: Adaptation Mechanisms of Weed Vegetation to the Gradient of Soil Constraints
(Public Library Science, San Francisco, 2014)
Questions: Effects of soil on vegetation patterns are commonly obscured by other environmental factors; clear and general relationships are difficult to find. How would community assembly processes be affected by a substantial ...
Novel simple methods for the synthesis of single-phase valentinite Sb2O3
(Springer, Dordrecht, 2014)
Several methods with solid and dissolved reactants were investigated as possible routes for synthesis of single-phase valentinite Sb2O3. The methods are based on simple chemical reaction between SbCl3 and NaOH. The method ...
Differential response of antioxidative systems of maize (Zea mays L.) roots cell walls to osmotic and heavy metal stress
(Wiley, Hoboken, 2014)
An analysis of peroxidase and ascorbate oxidase activity, phenolic content and antioxidant capacity of isolated maize root cell walls was performed in controls and plants stressed with polyethylene glycol (PEG) or heavy ...
Service life test of the NiSn coatings as cathodes for hydrogen evolution in industrial chlor-alkali electrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this work the "service life test" (SLT) of the NiSn alloy coatings as cathodes for the hydrogen evolution reaction (HER), deposited onto Ni 40 mesh at different current densities from the bath containing 0.1 mol dm(-3) ...
On 2D generalization of Higuchi's fractal dimension
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
We propose a new numerical method for calculating 2D fractal dimension (DF) of a surface. This method represents a generalization of Higuchi's method for calculating fractal dimension of a planar curve. Using a family of ...
Comparative study of the genotoxic response of freshwater mussels Unio tumidus and Unio pictorum to environmental stress
(Springer, Dordrecht, 2014)
Genotoxic response of freshwater mussels U. tumidus and U. pictorum to environmental stress was studied using comet assay on hemocytes and gill cells. The mussels were acclimated to controlled laboratory conditions for 10 ...
Structural, electrical and magnetic properties of nickel manganite obtained by a complex polymerization method
(Elsevier Sci Ltd, Oxford, 2014)
Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized ...
Lead immobilization by geopolymers based on mechanically activated fly ash
(Elsevier Sci Ltd, Oxford, 2014)
In this paper, the effectiveness of geopolymers based on initial and mechanically activated fly ash in immobilization of lead was investigated. Fly ash (FA) was firstly mechanically and then alkali activated at room ...
