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 ...
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 ...
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 ...
Novel uniaxial anemometer containing NTC thick film segmented thermistors
(IEEE, New York, 2008)
A novel uniaxial anemometer was created using a NTC thick film segmented therinistor to measure wind speed and direction. The anemometer operated on the principle of heat loss caused by the air volume flow and air speed. ...
Differential balanced symmetrical T-type LC for EMI chip filters and their EM simulation
(IEEE, New York, 2008)
This paper presents the newly developed differential balanced symmetrical T-type LC EMI chip filters. Initially, two different types of T-type LC filters, produced by multilayer green sheet technology, were characterized ...
Spin-trapping of oxygen free radicals in chemical and biological systems: New traps, radicals and possibilities
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The choice of the spin-trap that is to be applied in any EPR study represents the crossroad between a comprehensive investigation and an "ordinary" quantification of production of radicals. So, the scope of our study was ...
Evaluation of antioxidant capacity of Allium ursinum L. volatile oil and its effect on membrane fluidity
(Elsevier Sci Ltd, Oxford, 2008)
A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic ...
Effectiveness of phenoxyl radicals generated by peroxidase/H2O2-catalyzed oxidation of caffeate, ferulate, and p-coumarate in cooxidation of ascorbate and NADH
(Springer Japan Kk, Tokyo, 2008)
The rate of ascorbate and nicotinamide adenine dinucleotide plus hydrogen (NADH) cooxidation (i.e., their nonenzymic oxidation by peroxidase/H2O2-generated phenoxyl radicals of three hydroxycinnamates: caffeate, ferulate ...
Ectomycorrhiza and water transport
(Springer-Verlag Berlin Heidelberg, 2008)
In temperate and boreal regions, seasons are characterized by two major factors - temperature and water availability. As water availability is affecting essential processes like nutrition and photosynthesis, it is of central ...
