Mycorrhiza formation enhances adaptive response of hybrid poplar to drought
(New York Acad Sciences, New York, 2005)
Mycorrhized and nonmycorrhized plants of hybrid poplar (Populus tremula L. x Populus tremuloides Mich) were cultivated in petri dishes until the amount of water became limiting (detected by a decrease of photosynthetic ...
Polymorphism in liquid crystals from star-shaped mesogens
(Taylor & Francis Ltd, Abingdon, 2007)
Star-shaped molecules, based on a phloroglucinol core with three oligobenzoate arms, are powerful mesogens that can be combined to columnar liquid crystalline materials and soft organic crystals. The structural properties ...
Electronic and transport properties of contacts between molybdenum sulfide nanowires and gold electrodes
(Amer Inst Physics, Melville, 2008)
We report unique electronic and transport properties of contacts between a molybdenum sulfide nanowire and a gold electrode. The pointlike contacts exhibit a remarkable transparency for the charge carrier injection, which ...
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 ...
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 ...
Kinetics of the hydrogen evolution reaction on Fe-Mo film deposited on mild steel support in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The mechanism and kinetics of the hydrogen evolution reaction were studied. in 1.0 mol dm(-3) NaOH solution on Fe-Mo alloy electrodes prepared by electrodeposition at constant current densities from a pyrophosphate bath. ...
Morphology and phase composition of as-deposited and recrystallized Ni-Mo-O powders
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The Ni-Mo-O alloy powders were electrodeposited from ammonium sulfate containing electrolytes for different Ni/Mo ions concentration ratios. Electrodeposition was investigated by the polarization measurements. The morphology, ...
