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 ...
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 ...
Spectral and fractal analysis of biosignals and coloured noise
(IEEE, New York, 2007)
The amplitude power spectra and fractal dimensions of surrogate data designed as coloured noise were compared with spectra and FDs of biosignals in order to improve the tools for brain activity analysis. It is interesting ...
Dielectric investigations of barium titanate doped with 0.5 mol.% antimony
(11th International Conference and Exhibition of the European Ceramic Society 2009, 2009)
In the present paper the results of new ceramics of BaTiO3 with 0,5 mol% antimony were investigated by means of dielectric spectroscopy. Dielectric spectra of barium titanate with 0,5 mol% antimony revealed three parts: ...
A Characterization of Ceramic SMD Inductors for PCB Applications
(IEEE, New York, 2009)
In this paper, a measurement technique, characterization and parameters extraction of SMD inductors for PCB applications are presented. These components, manufactured by Fair-Rite, are measured and characterized using a ...
Electrical properties of barium bismuth titanate
(Faculty of Technology, University of Novi Sad Bul. cara Lazara 1, 21000 Novi Sad, Serbia, 2009)
Family of bismuth oxides was discovered more than 50 years ago by Aurivillius [1]. Recently, there has been renewed interest in the properties of the Aurivillius phases as temperature-stable ferro-piezoelectrics [2]. Several ...
Structure and Properties of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(11th European Meeting on Ferroelectricity, Bled, Slovenia, 3-7 September 2007, 2007)
Recently there has been renewed interest in the properties
of the Aurivillius phases as temperature-stable ferropiezoelectrics
[1 ]. Several bismuth-layered crystal structures
and their properties have been investigated ...
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 ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Čačak : Technical Faculty, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, Ti02 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
