Far infrared study of local impurity modes of Gd doped PbTe
(Elsevier Science Sa, Lausanne, 2008)
Single crystal samples of lead telluride doped with Gd were grown using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 K to 300 K were measured. The experimental diagrams were ...
High seed Mn content does not affect germination of in vitro produced Centaurium pulchellum seeds
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The effect of high Mn2+ content on Centaurium pulchellum seed germination has been investigated. Seeds containing extremely high Mn2+ content were produced by culturing single-node flowering explants for 2 months in the ...
Monitoring of transformations in bentonite after NaOH-TMA treatment
(Elsevier Sci Ltd, Oxford, 2007)
Semi-quantitative methods of X-ray diffraction and FTIR-spectroscopy, accompanied by electron microscopy, X-ray microanalysis and others were used to monitor structural-phase reorganizations occurring in a smectite-gypsum ...
Estimation of parameter k(max) in fractal analysis of rat brain activity
(New York Acad Sciences, New York, 2005)
We recorded electrocortical activity in anesthetized rats and constructed kmax new self-similar time series, applying Higuchi's algorithm. The aim of this study was to estimate value of the parameter k(max). in order to ...
Anti-tumor effect of Coriolus versicolor methanol extract against mouse B16 melanoma cells: In vitro and in vivo study
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
Numerous studies have shown immunostimulatory and anti-tumor effects of water and standardized aqueous ethanol extracts derived from the medicinal mushroom, Coriolus versicolor, but the biological activity of methanol ...
Kinetic study of the hydrogen oxidation reaction on sub-stoichiometric titanium oxide-supported platinum electrocatalyst in acid solution
(Elsevier Science Bv, Amsterdam, 2009)
The kinetics and mechanism of the hydrogen oxidation reaction were studied in 0.5 mol dm(-3) HClO4 solution on an electrode based on titanium oxide with Magneli phase structure-supported platinum electrocatalyst applied ...
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 ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
(Elsevier Sci Ltd, Oxford, 2009)
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 degrees C (heating rates 5, 10 and 15 degrees ...
Probing the lignin nanomechanical properties and lignin-lignin interactions using the atomic force microscopy
(Elsevier, Amsterdam, 2001)
By combining atomic force microscopy (AFM) force and environmental scanning electron microscopies (ESEMs), herein we present an evidence for the existence of strong intermolecular forces, which are responsible for holding ...
Photoacoustic properties of sintered NiO
(Carl Hanser Verlag, Munich, 2004)
The thermal diffusivity of NiO pellets was determined by the photoacoustic technique. A NiO powder, with a purity of 99.95%, was pressed into pellets 10 mm in diameter. The average agglomerate size of the NiO powder was ...
