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 ...
Germination of Iva xanthifolia, Amaranthus retroflexus and Sorghum halepense under media with microorganisms
(Journal of Plant Diseases and Proctection, Supplement, 2008)
This investigation focused on testing the germination of three weed species (Iva xanthifolia Nutt., Amaranthus retroflexus L. and Sorghum halepense (L.) Pers.) under the influence of several microorganisms: a population ...
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 ...

(Belgrade : University, Faculty of Biology, 2009)
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. ...
Micro Raman and fluorescence spectroscopy of lignin model compounds / Primena mikroramanske i fluorescentne spektroskopije na ispitivanje lignin model jedinjenja
(Serbian Plant Physiology SocietyInstitute for Biological Research "Siniša Stankovic", University of Belgrade, 2009)
PROPERTIES OF LANTHANUM DOPED BARIUM TITANATE PRODUCED FROM NANOPOWDERS
(4'n Workshop Fabrication, Properties & Applications of Electroceramic Nanostructures, Abstracts June 26-28,2008 Genoa, Italy, 2008)
As a first discovered ferroelectric ceramic, barium titanate has become one of the
most extensively investigated ceramic materials used in electronics. For many years, A- and
B-site dopants have been used to modify the ...
EFFECT OF LANTHANUM ON MICROSTRUCTURE OF BaTiO3: PREPARED BY POLYMERIC PRECURSORS METHOD
(3'd Workshop Nanostructured Materials : Processing and Application September 2, 2007 Bled, Slovenia, 2007)
Due to its high dielectric constant and low loss characteristics, barium titanate has
been used in many applications, such as capacitors, piezoelectric devices, positive
temperature coelficient thermistors, semiconductors ...
