Analysis of early-stage sintering mechanisms of mechanically activated BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Barium-titanate powder was mechanically activated in a planetary-ball mill for 60 and 120 minutes. Non-isothermal sintering of non-activated and activated powder samples was investigated using a dilatometer in the temperature ...
Infrared properties of sintered α-MnSe
(Carl Hanser Verlag, 2006)
Far-infrared reflection spectra of sintered α-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak resulting ...
Optical absorption in molybdenum disulfide nanotubes
(Spie-Int Soc Optical Engineering, Bellingham, 2006)
Symmetry based calculations of the polarized optical absorption in single-wall MoS2 nanotubes are presented. Optical conductivity tensor for the individual tubes, using line group symmetry implemented POLSym code and ...
The influence of tribophysical activation on non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., ...
COMPARISON OF DIFFERENT MATHEMATICAL MODELS IN DECONVOLUTION OF LIGNIN FLUORESCENCE SPECTRA
(Society of Physical Chemists of Serbia, 2006)
We analysed fluorescence spectra of poplar lignin and lignin model compound, using
gaussian, log-normal and exponential power model. Asymmetric models show wavelength
positions of components in a complex molecule. Gaussian ...
Structural - Phase transformations in bentonite after NaOH-BaCl2 treatment in conditions of water deficiency
(Silicates Industriels, 2006)
The methods of X-ray diffraction, FTIR-spectroscopy, electron microscopy, X-ray microanalysis and others were used for investigation of structural phase reorganization, which occurs in a montmorillonite-gypsum mixture ...
Counterpropagating beams in nematic liquid crystals
(Optics Express, 2006)
The behavior of counterpropagating self-trapped optical beam structures in nematic liquid crystals is investigated. A time-dependent model for the beam propagation and the director reorientation in a nematic liquid crystal ...
Trovanje kamforom - spektralna analiza aktivnosti mozga pacova / Camphor oil poisoning: Spectral analysis of rat brain activity
(Serbian Union of Biological Sciences, 2006)
We have decided to detect the seizure brain activity induced by camphor essential oil in rats, as there are still reports of severe intoxication in humans by camphor. The experiments were performed on adult Wistar male ...
Arrival times and biometric correlation in Sylviine warblers in Vojvodina, Serbia
(Journal of OrnithologySpringer, 2006)
Five of the 17 western Palearctic warblers of the genus Sylvia occur in Vojvodina, the northern province of Serbia. Of these, only two, the Blackcap (S. atricapilla) and Greater Whitethroat
(S. communis), are common, ...
