Senescence- and drought-related changes in peroxidase and superoxide dismutase isoforms in leaves of Ramonda serbica
(Oxford Univ Press, Oxford, 2006)
Ramonda sp. (Gesneriaceae) is an endemic and relic plant in a very small group of poikilohydric angiosperms that are able to survive in an almost completely dehydrated state. Senescence- and drought-related changes in the ...
Assessment of extinction risk and reasons for decline in sturgeon
(Springer, Dordrecht, 2006)
Sturgeon populations in the Danube River have been affected by a combination of hydropower development, over-harvesting, habitat degradation from agricultural and industrial practices and from urbanization. The effects of ...
Infrared properties of sintered alpha-MnSe
(Carl Hanser Verlag, Munich, 2006)
Far-infrared reflection spectra of sintered alpha-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak ...
Magneli phase titanium oxides as catalyst support - Electrochemical behavior of Ebonex/Pt catalysts
(Journal of New Materials for Electrochemical Systems, 2006)
The impregnation method has been applied to synthesize platinum nanoparticles on Magneli phase titanium oxide powder (Ebonex). Surface area of the Ebonex support was determined by BET technique. Distribution and morphology ...
Infrared properties of sintered α-MnSe
(Carl Hanser Verlag, 2006)
Far-infrared reflection spectra of sintered α-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak resulting ...
Optical absorption in molybdenum disulfide nanotubes
(Spie-Int Soc Optical Engineering, Bellingham, 2006)
Symmetry based calculations of the polarized optical absorption in single-wall MoS2 nanotubes are presented. Optical conductivity tensor for the individual tubes, using line group symmetry implemented POLSym code and ...
Electrical characterization of the grain-boundary region of SnO2 varistors
(Trans Tech Publications Ltd, 2006)
The effect of Co, Cr and Nb on the electrical properties of the grain boundaries of SnO2-based varistors was investigated. The powders were prepared by the method of evaporation and decomposition of solutions and suspensions. ...
Analysis of early-stage sintering mechanisms of mechanically activated BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Barium-titanate powder was mechanically activated in a planetary-ball mill for 60 and 120 minutes. Non-isothermal sintering of non-activated and activated powder samples was investigated using a dilatometer in the temperature ...
Sixty years of the theory of B. Ya. Pines
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Temperature dependence of fractal dimension of grain boundary region in SnO2 based ceramics
(Springer, New York, 2006)
Fractal dimensions of grain boundary region in doped SnO2 ceramics were determined based on previously derived fractal model. This model considers fractal dimension as a measure of homogeneity of distribution of charge ...
