Stability and electronic properties of rhenium sulfide nanotubes
(Wiley-V C H Verlag Gmbh, Weinheim, 2009)
The structural properties, the stability and the electronic properties of single-walled ReS2 nanotubes are studied for-the first time using the density-functional tight-binding method (DFTB). It is found, that the properties ...
A wet-chemical route for the preparation of Ni-BaCe0.9Y0.1O3-delta cermet anodes for IT-SOFCs
(Elsevier, Amsterdam, 2009)
Nano-sized BaCe0.9Y0.1O3 - delta (BCY10) protonic conductor powders were used to prepare Ni-BCY10 cermets for anode-supported intermediate temperature solid oxide fuel cells. A new wet-chemical route was developed starting ...
Seasonal changes in condition, hepatosomatic index and parasitism in sterlet (Acipenser ruthenus L.)
(Scientific Technical Research Council Turkey-Tubitak, Ankara, 2009)
Measurements of biomarker responses in fish from contaminated sites could provide valuable data for environmental risk assessment. Biomarkers are sensitive to both environmental pollution and confounding factors that are ...
Far infrared properties of sintered NiO
(Elsevier Sci Ltd, Oxford, 2007)
Far infrared reflection spectra of NiO polycrystals sintered at 1100 degrees C for various times (30-240 min) were measured at room temperature using a FTIR Spectrometer-Brucker 113V. The measured spectra depended on the ...
A detailed XRD and FTIR analysis of Bi2O3 doped ZnO-SnO2 ceramics
(A Global Road Map for Ceramic Materials and Technologies: Forecasting the Future of Ceramics, Intern, 2008)
ZnO-SnO2 ceramics were prepared with a traditional powder mixed oxide route by mixing starting powders of ZnO and SnO2 in the molar ratio 2:1 and adding small amounts (0.5; 1.0; and 1.5 molar%) of Bi 2O3. These mixtures ...
Morphology and composition of the Fe-Ni powders electrodeposited from citrate containing electrolytes
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposition of the Fe-Ni powders from citrate containing electrolytes for different Ni/Fe ions concentration ratios, using Fe(Ill) and Fe(II) salts at pH 4.5 and pH 4.0 respectively was investigated by the ...
Microstructural characterization of mechanicallyactivated ZnO powders
(Wiley, Hoboken, 2008)
In this paper, changes of microstructural characteristics of disperse systems during mechanical activation of zinc oxide (ZnO) have been investigated. ZnO powder was activated by grinding in a planetary ball mill in a ...
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 ...
Occurrence and Distribution of Grapevine Yellows Caused by Stolbur Phytoplasma in Montenegro
(Wiley, Hoboken, 2009)
In August 2008, grapevine yellows (GY)-like symptoms were observed in vineyards near Podgorica, Montenegro. A survey of the grape growing area of Montenegro was conducted to identify and determine the distribution of ...
Far infrared spectroscopy of Pb0.85Sn0.15Te alloy doped with Ni
(Carl Hanser Verlag, Munich, 2008)
Far infrared reflectivity spectra of single crystal Pb0.85Sn0.15Te doped with Ni were measured in the temperature range between 10 K and 300 K. Analysis of the experimental spectra was made using a fitting procedure based ...
