Far infrared properties of PbTe doped with cerium
(Elsevier Science Sa, Lausanne, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are presented. The experimental data were numerically ...
Photopic vision in eels - Evidences of color discrimination
(New York Acad Sciences, New York, 2005)
Several classes of second-order retinal neurons have been studied electrophysiologically in European eel (Anguilla anguilla) from two different localities, Lake Seliger in Russia and the coastal waters of the Adriatic Sea ...
Characterization and properties of barium bismuth titanate
(Faculty of Technology, University of Novi Sad, 2009)
BaBi4Ti4O15 (BBiT) was prepared from stoichiometric amounts of BaTiO3 (BT) and Bi4Ti3O12 (BIT) obtained
via mechanochemical synthesis. Mechanochemical synthesis was performed in air atmosphere in a planetary
ball mill. ...
Synthesis of BaTiO3 from a mechanically activated BaCO3-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
History and Challenges of Barium Titanate: Part II
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
Barium titanate is the first ferroelectric ceramics and a good candidate for a variety of applications due to its excellent dielectric, ferroelectric and piezoelectric properties,. Barium titanate is a member of a large ...
Spin-trapping of oxygen free radicals in chemical and biological systems: New traps, radicals and possibilities
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The choice of the spin-trap that is to be applied in any EPR study represents the crossroad between a comprehensive investigation and an "ordinary" quantification of production of radicals. So, the scope of our study was ...
Population viability analysis and potential of its application to Danube sturgeons
(Srpsko biološko društvo, Beograd, i dr., 2009)
Sturgeon species in the Danube River basin have experienced severe decline. Besides overexploitation, habitat loss, and pollution, they are further endangered by lack of efficient policy and management, as well as by serious ...
Improved total conductivity of nanometric samaria-doped ceria powders sintered with molten LiNO3 additive
(Elsevier, Amsterdam, 2009)
Nanometric 20% molar Sm-doped ceria (SDC20) powders were synthesized by co-precipitation in the presence of N, N, N', N' tetramethylethylendiamine (TMEDA). SDC20 powders were sintered using lithium nitrate salt in various ...
Decline in the Index of Biotic Integrity of the Fish Assemblage as a Response to Reservoir Aging
(Springer, Dordrecht, 2009)
The fish assemblage from reservoir Medjuvrsje was monitored over the 1955-2000 period. The Medjuvrsje Reservoir is one of the oldest Serbian reservoirs formed in 1953. Ichthyofauna was sampled in 1955, 1984, 1991 and 2000. ...
Effect of low temperature on rooting rate and carbohydrate content of Fritillaria meleagris bulbs formed in culture in vitro
(Srpsko biološko društvo, Beograd, i dr., 2008)
