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 ...
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 ...
Peroxide processing in photosynthesis: antioxidant coupling and redox signalling
(Royal Soc, London, 2000)
Photosynthesis has a high capacity for production of hydrogen peroxide (H2O2), but the intracellular levels of this relatively weak oxidant are controlled by the antioxidant system, comprising a network of enzymatic and ...
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 ...
Infrared reflection spectroscopy of Zn2SnO4 thin films deposited on silica substrate by radio frequency magnetron sputtering
(Elsevier Science Sa, Lausanne, 2008)
Single-phase zinc-stannate thin films of different thickness values were prepared by radio frequency magnetron sputtering on a silica substrate. Rietveld analysis of X-ray diffraction data confirmed that the films had an ...
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 ...
Aquaporins in poplar: What a difference a symbiont makes!
(Springer, New York, 2005)
The formation of ectomycorrhizas, a tight association between fine roots of trees and certain soil fungi, improves plant nutrition in a nutrient-limited environment and may increase plant survival under water stress ...
A novel approach to modeling and simulation of NTC thick-film segmented thermistors for sensor applications
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2007)
This paper describes the design, modeling, simulation, and fabrication of thick-film segmented thermistors. These thermistors were printed on alumina using negative temperature coefficient 3K3 paste, composed of nanometer ...
