Structural and electrical properties of sintered zinc-titanate ceramics
(Elsevier, 2009)
The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO2 were mechanically activated in a planetary ...
Aktivnost alkalne fosfataze u kosti nakon implantacije nanočestičnog kalcijum-kobalt hidroksiapatita
(Beograd : Institut tehničkih nauka, 2009)
Istraživanje je sprovedeno sa ciljem da se dokaže aktivnost alkalne fosfataze, lokalizovane u dekalcifikovanoj kosti, uzete sa leve strane mandibule pacova, u kojoj je arteficijalno napravljen defekt i implantiran nano ...
Mechanochemical synthesis and electrical conductivity of nanocrystalline δ-Bi2O3 stabilized by HfO2 and ZrO2
(Belgrade : Serbian Chemical Society, 2009)
A powder mixture of α-Bi2O3 and HfO2, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill under air, using zirconium oxide vials and balls as the milling medium. After 50 h of milling, the ...
Dielectric properties of BaTiO3 doped with Er203 and Yb203 based on intergranular contacts model
(Hoboken, NJ : John Wiley & Sons, 2009)
Taking into account that microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of these material, in this study, the model of ...
Electrical properties of mechanochemicaly activated cordierite ceramics
(Kiev, 2009)
Three-component oxide mixture was prepared containing MgO+Al2O3+SiO2 in a 2:2:5 ratio with addition of 10% Bi203. Mixtures were mechanically activated in range from 5 to 240 minutes in a mill with ceramic balls, and sintered ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
(Elsevier, 2009)
PbTe and Pb0.85Sn0.15Te single crystals, doped with Pd, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and 300 K. The experimental spectra were numerically ...
Mechanochemistry of titanium oxides
(Belgrade : Association of the Chemical Engineers of Serbia, 2009)
Mechanochemistry represents an alternative route in synthesis of nanomaterials. Mechanochemical routes are attractive because of their simplicity, flexibility, and ability to prepare materials by solid state reactions at ...
Far infrared properties of sintered Pb0.9Sn0.1Te doped with palladium
(Springer, 2009)
Far infrared reflectivity spectra of sintered Pb 0.9Sn 0.1Te doped with 0.2 and 2 at.% Pd are measured. The experimental results are analyzed using a fitting procedure based on a modified plasmon-phonon interaction model. ...
Aerosol route in processing of nanostructured functional materials
(Osaka : Hosokawa Powder Technology Foundation, 2009)
The diversity and potentials of the aerosol route for making functional materials at the nano size level are reviewed. Among the methods currently used for nanophase processing, synthesis through dispersion phase (aerosol) ...
In vitro and in vivo performance of nanosized hydroxyapatite particles coated with poly-dl-lactide-co-glycolide as systems for drug delivery of tigecycline
(Belgrade : Institute of Technical Sciences of SASA, 2009)
Calcium-phosphate/poly(dl-lactide-co-glycolide) (CP/PLGA) composite biomaterial in granular form showed a high potential in the reconstruction of bone tissue. Compared to pure polymers, the combination of CP with biodegradable ...
