Influence of mechanical activation on microstructure and crystal structure of sintered MgO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100o-1400oC for 2h. The decrease in powder’s ...

Electrochemical Behaviour of V2O5 Xerogel and V2O5 Xerogel/C Composite in an Aqueous LiNO3 and Mg(NO3)(2) Solutions
(Acta Physica Polonica A, 2010)
We synthesized both the V2O5 xerogel and the composite V2O5 xerogel/C starting from the solution of V2O5 in hydrogen peroxide. After the characterization by XRD, thermal (TCA-DTA), SEM methods and by particle size analysis, ...
Far infrared properties of PbTe doped with Hg
(Bucharest: Integra Natura Omnia et Aeterna, 2010)
Single crystal samples of PbTe doped with Hg were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with 0.5 at. % Hg; 0.9 at. % Hg and 1.4 at. % Hg. The plasma ...
Thermal diffusivity of single crystal Bi0.9Sb0.1
(Belgrade : International Institute for the Science of Sintering, 2010)
A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (00l) were determined from PA photoacoustic phase and ...
Strategies for the Scientific Progress of the Developing Countries in the New Millennium: The cases of Serbia, Slovenia and South Korea
(Universität Dortmund, 2010)
The quality and significance of scientific research in any society could be used as mirrors of its prosperity. By comparing two cases of prosperous scientific management, of South Korea and Slovenia, with the problems of ...

(Bucharest: Integra Natura Omnia et Aeterna, 2010)
In this paper are presented the far-infrared reflectivity spectra for a cleaved FeS 2 sample measured at roam temperature and at 77 K.
Nanostructured materials for optoelectronic applications
(Warsaw: Polish Academy of Sciences, 2010)
Study and optimization of new nanoscale materials useful for optoelectronic application have been considered. The search for the effective nanostructured materials has been revealed in two directions: to optimize the ...
Optical far infrared properties of PtSb2
(Bucharest: Integra Natura Omnia et Aeterna, 2010)
Far infrared reflection spectra measured at room temperature were used to investigate vibrational properties of PtSb2 single crystals. The experimental results were analyzed using a dielectric function taking into account ...
Uticaj gama zračenja na molekulsku masu i staklasti prelaz PLLA
(Hemijska industrija, 2010)
U ovom radu ispitivan je uticaj gama zračenja na molekulsku masu i staklasti prelaz poli-L-laktida (PLLA). S obzirom da je PLLA pri izlaganju visokoenergijskom zračenju sklon kidanju lanaca i velikoj degradaciji, promene ...
