Infrared reflectance of single-crystal jarandolite, CaB3O4(OH)3
(Twickenham : Mineralogical Soc., 2007)
Polarized far- and mid-infrared reflectance spectra were measured at room temperature for the new mineral species jarandolite, CaB3O4(OH)(3), for the two principal directions. Thirty three vibration modes for (E) over right ...
Phase evolution in Ce-doped yttrium-aluminum-based particles derived from aerosol
(Elsevier Sci Ltd, Oxford, 2007)
The common nitrates precursor solution leading to the Y3Al5O12:Ce3+ (YAG:Ce) composition with 2 at.% of cerium, is ultrasonically atomised and introduced into the tubular flow reactor at 320 degrees C. Having in mind that ...
Investigation on possibility of mechanochemical synthesis of CaTiO3 from different precursors
(Elsevier Sci Ltd, Oxford, 2007)
Recently, mechanochemical synthesis was widely used in preparation of perovskite type of materials, such as BaTiO3, PbTiO3, PZT, etc. In this work, the possibility of mechanochemical synthesis of CaTiO3 from different ...
ZnO varistors from intensively milled powders
(Elsevier Sci Ltd, Oxford, 2007)
Two ways of application of intensive milling in ZnO varistors processing were compared. First was intensive milling of mixture of previously prepared constituent phases. In this case, intensive milling was applied only to ...
ZnO varistors with reduced amount of additives prepared by direct mixing of constituent phases
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to reduce number of additives using new method of preparation, refered as "direct mixing of the constituent phases". The method is based on sintering of a mixture of constituent phases with the ...
Deconvolution of fluorescence spectra: Contribution to the structural analysis of complex molecules
(Elsevier Science Bv, Amsterdam, 2007)
Fluorescence spectroscopy is a sensitive analytical tool in the studies of both simple and complex molecular structures. In complex molecules, however, determining the number and position of components may give a specific ...
Electronic properties and optical spectra of MoS2 and WS2 nanotubes
(Amer Physical Soc, College Pk, 2007)
Symmetry based calculations of the polarized optical absorption in single-wall MoS2 and WS2 nanotubes are presented. Optical conductivity tensor for the individual tubes, using line group symmetry and density-functional ...
Optimization of processing parameters for preparation of LaNiO3 thin films from the citrate precursors
(Elsevier Sci Ltd, Oxford, 2007)
Lanthanum nickel oxide (LaNiO3) is an electrically conductive ceramics, which has a potential use as electrode for ferroelectric thin films, multilayer actuators and many other electronic devices. In this work, LaNiO3 thin ...
Far infrared reflection spectroscopy of Zn2SnO4 ceramics obtained by sintering mechanically activated ZnO-SnO2 powder mixtures
(Elsevier Sci Ltd, Oxford, 2007)
A mixture of starting ZnO and SnO2 powders (molar ratio 2: 1) were mechanically activated for 10, 40, 80 and 160 min in a planetary ball mill and then isothermally sintered at 1300 degrees C for 2 h in order to obtain ...
Amur sleeper (Perccottus glenii Dubowski, 1877) spreading in the Danube river basin
(Wiley, Hoboken, 2007)
Whereas earlier Amur sleeper (Perccottus glenii) findings in the Danube River were only single specimens, data reported in this study represent the first record on establishment of a local population. An overview of the ...
