Microstructural investigation of the PZT films prepared from the suspension of nanocrystalline powders
(Elsevier Sci Ltd, Oxford, 2004)
PZT thin films of composition Pb(Zr0.52Ti0.48)O-3 were prepared by a novel method from the suspension of nanocrystalline PZT powders. The powders were obtained by mechanochemical synthesis. Films were deposited on silicon ...
Mechanochemical synthesis of gamma-Bi2O3
(Elsevier, Amsterdam, 2004)
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) ...
Strontium titanate films prepared by spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2004)
Strontium titanate thin films were prepared by spray pyrolysis technique. Deposition parameters, such as solution concentration, time and temperature of deposition, and flow rate of carrier gas were optimized to obtain ...
Changes in sterlet (Acipenser ruthenus L.) catch and length frequency distribution in the Serbian part of the Danube River during the twentieth century
(Polish Academy of Sciences, 2004)
Data from a sample of 262 sterlet (Acipenser ruthenus L.) specimens from the Serbian part of the Danube River were compared with data collected between 1948 and 1967. The recent sample was caught between September 2002 and ...
Photoacoustic properties of sintered NiO
(Walter De Gruyter Gmbh, Berlin, 2004)
The thermal diffusivity of NiO pellets was determined by the photoacoustic technique. A NiO powder, with a purity of 99.95 %, was pressed into pellets 10 mm in diameter. The average agglomerate size of the NiO powder was ...
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 ...
Значај производних и социјалних функција букових шума у Србији
(Београд : Министарство шумарства ФНРЈ, 2004)
Klasifikacije funkcija šuma su mnogobrojne i različite, zavisno od vremena u kome su nastale i od kriterijuma prema kojima su sačinjene. Jedna od najsveobuhvatnijih i za naše i evropske uslove najznačajnijih je FAO ...
Ornithologycal importance of Gruža accumulation
(Matica srpska, 2004)
The damming of the middle course of the Gruža River, done in order to supply drinking and technical water for the Kragujevac District, resulted in the forming of the Gruža reservoir. This lake fills the depression of the ...
Istorija primene antibiotika
(Srpsko hemijsko društvo, 2004)
Antibiotici su hemijska organska jedinjenja (uglavnom mikrobiološkog porekla) ili njihovi derivati, koji imaju sposobnost da spreče rast ili unište druge mikroorganizme [1]. To je grupa jedinjenja vrlo različitih struktura ...
Wintering Waterfowl of Serbian portion of Danube River: counts 1999-2003
(AKDENIZ UNIVERSITY – ANTALYAHACETTEPE UNIVERSITY – ANKARA, 2004)
IWC (International Water Bird Census) represents the greatest survey program of biodiversity in the world that deals with the birds of wetland habitats. Information that is gathered by census method of IWC in six Eurasian ...
