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 ...
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 ...
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 ...
Pairing in planar organic superconductors
(Institute of Physics,Belgrade Pregrevica 118, Zemun, Serbia and Montenegro, 2004)
The nature of superconductivity in planar organics is still a controversial problem. We investigate theoretically d-wave and anisotropic s-wave pairing in k-(BEDT-TTF)2X compounds. Assuming strong dimerization, we consider ...
Effects of environmental factors on breeding dynamics of the Great Crested Grebe Podiceps cristatus in Vojvodina (Serbia)
(The Société d’Études Ornithologiques de France (SEOF), 2005)
The Great Crested Grebe (Podiceps cristatus) is widely distributed in Vojvodina, the northern province of the Republic of Serbia. It breeds in colonies, on different types of aquatic habitats,
whether they are natural, ...
HRONOLOGIJA GNEŽĐENJA ĆUBASTOG GNJURCA Podiceps cristatus (Linnaeus, 1758) U SPECIJALNOM REZERVATU PRIRODE "STARI BEGEJ-CARSKA BARA"
(Prirodno-matematički fakultet, Institut za biologiju, Novi SadGoransko-ekološki pokrtet, Sremska Mitrovica, 2001)
Ćubasti gnjurac je ptica koja se nalazi na Evropskoj crvenoj listi, kao ranjiva vrsta. U cilju provere statusa ove vrste na području Vojvodine, praćeno je gnežđenje ćubastog gnjurca u specijalnom rezervatu prirode "Stari ...
Heavy metals concentration in Paulownia elongata S.Y. Hu and Paulownia fortunei Seem. Hemsl. Leaves

Spectrofluorimetric Analysis of Synthetic and isolated lignin from Omorika
(22th International Symposium on Biophysic, 2004)
Lignin is the one of the main constituitive polymers of the plant cell wall that protect plant cell from different kond of stress. Lignin precursors, the plenolic alcohols, belong to the group of phenylpropanoid compounds. ...
