Synthesis and characterization of MoOx-Pt/C and TiOx-Pt/C nano-catalysts for oxygen reduction
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The oxygen reduction reaction (ORR) was studied at carbon supported MoOx-Pt/C and TiOx-Pt nanocatalysts in 0.5 mol dm(-3) HClO4 solution, at 25 degrees C. The MoOx-Pt/C and TiOx-Pt/C catalysts were prepared by the polyole ...
Induction of peroxidases and superoxide dismutases in transformed embryogenic calli of alfalfa (Medicago sativa L.)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
Peroxidase (POD) and superoxide dismutase (SOD) enzyme activities were analyzed in non-regenerative transformed embryogenic lines of alfalfa (Medicago sativa L.) carrying wound-inducible oryzacystatin I (OC-I), wound-inducible ...
Mechanochemical synthesis of lead magnesium niobate ceramics in iron media
(Springer, New York, 2008)
The possibility of mechanochemical synthesis of the lead magnesium niobate (PMN) powders of the composition Pb(Mg1/3Nb2/3)O-3 in iron vials was investigated. According to X-ray and energy-dispersive spectroscopy (EDS) ...
The Electrophoretic Deposition of Lanthanum Manganite Powders for a Cathode-Supported Solid Oxide Fuel Cell in Planar and Tubular Configurations
(Wiley, Hoboken, 2008)
The purpose of this research was to obtain porous, high-quality cathodes for solid oxide fuel cells in both planar and tubular shapes. To accomplish this, cathodic electrophoretic deposition of the LaMnO3 powder (synthesized ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(Kluwer Academic Publ, Dordrecht, 2001)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
Free radical involvement in the generation of trans-root potential
(Wiley, Hoboken, 1998)
The identity of the naturally occurring compounds that accept electrons from plasma membrane-bound redox systems in vivo is obscure. We analysed the effect of ascorbate, oxygen, iron, as well as their free radical forms, ...
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 ...
Distribution of the Asiatic cyprinid Pseudorasbora parva in Serbia and Montenegro
(Wiley, Hoboken, 2004)
The first record of Pseudorasbora parva in the Balkan region was in 1977 in Sasko Lake, Montenegro and in 1978 it was found in Serbia. Since then, this species has spread to almost all lowland rivers and has become a ...
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 ...
