Magnetic properties of pure and Ca and Sr doped LaMnO3 prepared by polymerisable complex method
(Maney Publishing, Leeds, 2009)
In this work, pure and Ca2+ and Sr2+ doped LaMnO3 powders were obtained using polymerisable complex method from citrate precursors. La2O3, Mn(NO3)(2) and citric acid were used for citrate formation, and ethylene glycol was ...
Generation of Hydroxyl Radical in Isolated Pea Root Cell Wall, and the Role of Cell Wall-Bound Peroxidase, Mn-SOD and Phenolics in Their Production
(Oxford Univ Press, Oxford, 2009)
The hydroxyl radical produced in the apoplast has been demonstrated to facilitate cell wall loosening during cell elongation. Cell wall-bound peroxidases (PODs) have been implicated in hydroxyl radical formation. For this ...
Temporal analysis of electroretinographic responses in fishes with rod-dominated and mixed rod-cone retina
(General Physiol And Biophysics, Bratislava, 2009)
Photoreceptor content of fish retinas could be accessed by comparative electroretinographic (ERG) studies using flickering light stimuli that could separate rod-mediated vision where critical flicker frequency (CFE, frequency ...
Electrical and transport properties of nickel manganite obtained by Hall effect measurements
(Springer, Dordrecht, 2009)
Intrinsic resistivity and carrier transport parameters of sintered nickel manganite samples (NTC thermistor grade) were determined using a Hall effect measurement system based on the van der Pauw method. Powder mixtures ...
EPR Spin-Trapping and Spin-Probing Spectroscopy in Assessing Antioxidant Properties: Example on Extracts of Catkin, Leaves, and Spiny Burs of Castanea sativa
(Springer, New York, 2009)
Electron paramagnetic resonance (EPR) spin-trapping and spin-probing techniques were applied to determine antioxidant activity of extracts of catkin, leaves, and spiny burs of Castanea sativa against physiologically relevant ...
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 ...
Relevance of the capacity of phosphorylated fructose to scavenge the hydroxyl radical
(Elsevier Sci Ltd, Oxford, 2009)
The hydroxyl radical ((OH)-O-center dot) has detrimental biological activity due to its very high reactivity. Our experiments were designed to determine the effects of equimolar concentrations of glucose, fructose and ...
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 ...
Antioxidant Properties of Phenolics in Castanea sativa Mill. Extracts
(University of Zagreb, 2009)
Using electron paramagnetic resonance (EPR) spectroscopy, antioxidant properties of chestnut extracts have been investigated as a source of phenolic compounds. In addition to their high antioxidant activities against ...
Color properties of movement detectors in the carassius gibelio (bloch, 1782) tectum opticum studied by selective stimulation of different cone types
(Srpsko biološko društvo, Beograd, i dr., 2009)
