An attempt to produce NiFe2O4 powder from electrodeposited Fe-Ni alloy powders by subsequent recrystallization in air
(Springer, Dordrecht, 2010)
The electrodeposition of the Fe-Ni powders from citrate-ammonium chloride containing electrolytes for different Ni/Fe ions concentration ratios at pH 4.0 was investigated by the polarization measurements. The morphology, ...
Raman study of structural disorder in ZnO nanopowders
(John Wiley & Sons Ltd, Chichester, 2010)
Raman scattering spectroscopy has been used for the characterization of zinc oxide nanoparticles obtained by mechanical activation in a high-energy vibro-mill and planetary ball mill. Raman modes observed in spectra of ...
Detection of Structural Features in Biological Signals
(Springer, New York, 2010)
In this article structures in biological signals are treated. The simpler-directly visible in the signals, which still demand serious methods and algorithms in the feature detection, similarity investigation and classification. ...
Characterisation of phenol oxidase and peroxidase from maize silk
(Wiley-Blackwell, Hoboken, 2010)
Silk of some maize genotypes contains a high level of phenolics that undergo enzymatic oxidation to form quinones, which condense among themselves or with proteins to form brown pigments. Two phenolic oxidizing enzymes, ...
An attempt to predict the mechanism of Mo-Ni-O powders electrodeposition from the results of their TEM analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The Mo-Ni-O powders were electrodeposited from ammonium sulfate containing electrolytes with different Mo/Ni ion concentration ratios. The phase composition of these powders was investigated using TEM. EDS and XRD analysis. ...
The effects of manganese and copper in vitro and in vivo on peroxidase catalytic cycles
(Elsevier Gmbh, Munich, 2010)
Here we present the results of in vitro and in vivo studies of the influence of Mn2+ and Cu2+ on the peroxidative and oxidative catalytic functions of class III peroxidase. Complex peroxidase catalysis by intermediates ...
Synthesis, characterization and electrocatalytical behavior of Nb-TiO2/Pt nanocatalyst for oxygen reduction reaction
(Elsevier Science Bv, Amsterdam, 2010)
In order to point out the effect of the support to the catalyst for oxygen reduction reaction nano-crystalline Nb-doped TiO2 was synthesized through a modified sol-gel route procedure. The specific surface area of the ...
Soil Properties and Trace Elements Contents Following 40 Years of Phosphate Fertilization
(Wiley, Hoboken, 2010)
Long-term application of P fertilizers may eventually result: in excess and/or toxic accumulations of trace elements and microelements in soil. The effect of monoammonium-phosphate (MAP) on basic soil properties (pH, CEC, ...
The effect of pH on the activity of soluble peroxidase in needles of Serbian spruce (Picea omorika (Panc.) Purkinye): application of a mathematical model
(General Physiol And Biophysics, Bratislava, 2010)
We studied the dependence of peroxidase (POD) activity on pH in crude extract of Picea omorika (Pane.) Purkinye needles and in its acidic and basic fractions, obtained by ion exchange chromatography. Nonlinear regression ...
Multiferroic bismuth manganite prepared by mechanochemical synthesis
(Elsevier Sci Ltd, Oxford, 2010)
Multiferroic bismuth manganite (BiMnO3) is known as a material that exhibits both ferromagnetic and ferroelectric properties making it interesting for various technological applications. Unfortunately, preparation of BiMnO3 ...
