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 ...
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 ...
Microstructural and compositional aspects of ZnO-based varistor ceramics prepared by direct mixing of the constituent phases and high-energy milling
(Elsevier Sci Ltd, Oxford, 2008)
ZnO-based varistor samples were prepared by the direct mixing of the constituent phases (DMCP) and sintering at 1100 degrees C for 2 h. The influence of the starting powder mixture's composition - the amounts of the ...
Characterization of polyphenol oxidase changes induced by desiccation of Ramonda serbica leaves
(Wiley, Hoboken, 2008)
Resurrection plants are able to dehydrate/rehydrate rapidly without cell damage by a mechanism, the understanding of which may be of ecological importance in the adaptation of crop plants to dry conditions. The o-diphenol ...
Microstructure of LaNiO3 thin films obtained by the spin-on technique from citrate precursors
(Elsevier Sci Ltd, Oxford, 2008)
The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from ...
New strain of 'Candidatus Phytoplasma ulmi' infecting Ulmus minor and U. laevis in Serbia
(Wiley, Hoboken, 2008)
Elm yellows (EY) phytoplasma (‘Candidatus Phytoplasma ulmi’) is the causal agent of a decline in American elms in North America, and in Eurasian elm species and hybrids in Europe (Lee et al., 2004). EY is known to infect ...
Structural characterization of mechanically milled ZnO: influence of zirconia milling media
(IOP Publishing Ltd, Bristol, 2008)
Zinc oxide nanoparticles were obtained by milling in a planetary ball mill with a zirconia milling assembly for up to 5 h in air. The samples were characterized by scanning electron microscopy, x-ray diffraction (XRD) and ...
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 ...
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 ...
