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 ...
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 ...
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 ...

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. ...
Ornithological diagnosis of Ovčarsko-Kablarska Gorge
(Univerzitet Crne Gore-Odsjek za BiologijuRepublički institut za Zaštitu PrirodePrirodnjački muzej Crne GoreUniverzitet Crne Gore-Institut za Biologiju mora, 2004)
Između planinskih masiva Ovčara i Kablara u zapadnoj Srbiji nalazi se klisura, nastala erozivnim radom Zapadne Morave. I pored antropogenih degradacionih procesa, Ovčarsko–Kablarska klisura se i dalje odlikuje velikom ...
