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 ...
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 ...

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 ...
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 ...
CHARACTERIZATION OF BARIUM BISMUTH TITANATE PREPARED BY MECHANICAL ASSISTED SYNTHESIS
(COST Action 539 - ELENA 4'th Workshop, Genoa, June 26-28, 2008, 2008)
Barium bismuth titanate (BaBi4Ti4O15 - BBiT) is an n=4 member of the Bi-base-layer-
structure ferroelectric oxide family (Aurivillius phase). A lot of aspects of the
preparation and properties of BBiTremain unexplored, ...
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)
Barium titanate thick films prepared by screen printing technique
(Faculty of Technology, University of Novi Sad Bul. cara Lazara 1, 21000 Novi Sad, Serbia, 2009)
Pure and doped with lanthanum and antimony barium titanate (BaTiO3-BT, BTL and BTS) powders were prepared by the polymeric organometallic precursors method (Pechini process-PPM) starting from citrate solutions.
For the ...
