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., ...
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 ...
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 ...
Anomalous lateral beam shift and total absorption due to excitation of surface waves in materials with negative refraction
(EUROPEAN PHYSICAL JOURNAL D, 2006)
We studied electromagnetic beam reflection from layered structures that include materials with negative refraction. Excitation of leaky surface waves leads to the formation of anomalous lateral shifts in the reflected beams ...
EFFECT OF POWDER SYNTHESIS ON CRYSTAL AND MICROSTRUCTURE OF BaTiO3
(COST Action 539 - ELENA 2'd Workshop, Brussels, November 15-16, 2006, 2006)
Barium titanate (BaTiO3) has been used in many applications such as multilayer
capacitors, piezoelectric ceramics, transducer devices, PTC resistor and has become one of
the most important ferroelectric ceramics. It is ...
Multiple forms of superoxide dismutase in the apoplast and whole-needle extract of Serbian spruce [Picea omorika (Panč.) Purkyně]
(Serbian Biological Society, 2006)
Activity and isoenzyme composition of superoxide dismutase in the apoplast and whole-needle extract of Picea omorika (Panč.) Purkyně, was studied. Total SOD activity of the soluble fraction of the needle extract exceeded ...
