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 ...
Ultrasonic de-agglomeration of barium titanate powder
(Ultrasonics Sonochemistry, 2008)
BaTiO3 (BT) powder, with average particle size of 1.4 mu m, was synthesized by solid-state reaction. A high-intensity ultrasound irradiation (ultrasonication) was used to de-agglomerate micro-sized powder to nano-sized ...
Analysis of nonisothermal sintering of zinc-titanate ceramics doped with MgO
(Springer, 2008)
The aim of this work is to analyze nonisothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO 2, and MgO (0, 1.25, and 2.5%) are mechanically activated for 15 ...
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 ...
PDLLA microparticles containing BSA: effect of formulation variables on size distribution
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Worldwide, there is u currently considerable care for the development of
biodegradable microspheres as systems for controlled release of medicaments. The major
disadvantage of traditional administration routes of medicaments ...
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) ...
Investigation of HeNe laser therapy influence on BCP/PLGA osseointegration: Experimental study
(Niš : University of Niš, 2006)
The efficiency of HeNe laser application in treatment of artificially caused bone defects in mandible of rats filled with biocomposite BCP/PLGA (bicalcium phosphate/polylactide-co-glycolide) was analyzed. Animals were ...
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 ...
Surface reconstruction during the adsorption/desorption of OH species onto Cu(111) and Cu(100) in O. 1 M NaOH solution
(Belgrade : Serbian Chemical Society, 2002)
The process of adsorption/desorption of OH- species onto Cu(111) and Cu(100) in 0.1M NaOH solution has been investigated by cyclic voltammetry and the potentiostatic pulse technique. Investigation of the electrochemical ...
