The influence of gamma radiation on the glass transition of hydroxyapatite/poly L-lactide composite
(Materials Science Forum, 2007)
Hydroxyapatite/poly L-lactide (HAp/PLLA) is a composite biomaterial which has been widely utilized for substitution and reparation of the hard bone tissue. It is well known that gamma irradiation has been successfully ...
Nanostructured ZrO2 powder synthesized by ultrasonic spray pyrolysis
(Surface Review and Letters, 2007)
The synthesis of nanostructured zirconia particles from aqueous colloidal dispersion of zirconia (zirconia sol) was carried out by ultrasonic spray pyrolysis method. The morphology of these nanostructured particles was ...
Fabrication, in vitro degradation and the release behaviours of poly(DL-lactide-co-glycolide) nanospheres containing ascorbic acid
(Colloids and Surfaces B: Biointerfaces, 2007)
Ascorbic acid (vitamin Q is essential for preserving optimal health and is used by the body for many purposes. The problem is that ascorbic acid easily decomposes into biologically inactive compounds making its use very ...

(Belgrade : Institute of Technical Sciences of SASA, 2007)
The First Conference on materials science and engineering, including physics, physical chemistry, condensed matter chemistry, and technology in general, was held in September 1995, in Herceg Novi. An initiative to establish ...
Sinteza, karakterizacija i degradacija nanosfera poli(DL-laktid-ko-glikolida) koje sadrže askorbinsku kiselinu
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2007)
Askorbinska kiselina (vitamin C) je izuzetno važan i organizmu neophodan vitamin. Ima ulogu reduktanta slobodnih radikala čime smanjuje oštećenja nastala oksidativnim stresom koji je uzrok ili pratilac mnogih bolesti. U ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Belgrade : International Institute for the Science of Sintering, 2007)
The effects of small amounts (0.5; 1.0 and 1.5 mol. %) of bismuth oxide on the microstructure and electrical properties of ZnO-SnO2 ceramics have been studied. Starting powders of ZnO and SnO2 were mixed in the molar ratio ...
Structural and magnetic characterization of LiMn1.825Cr0.175O4 spinel obtained by ultrasonic spray pyrolysis
(Materials Research Bulletin, 2007)
Quaternary spinel oxide LiMn1.825Cr0.175O4 Powder was synthesized by using an ultrasonic spray pyrolysis method, without additional annealing. The crystal structure of the as-prepared powder was revealed by X-ray powder ...
Far infrared properties of sintered PbTe doped with boron
(Belgrade : International Institute for the Science of Sintering, 2007)
Far infrared spectra of sintered PbTe doped with boron were analyzed. The measured infrared spectra were fitted using a modified plasmon-phonnon interaction model with two additional oscillators (at about 195 cm-1 and 285 ...
Reaction sintering of the 2ZnO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Sintering kinetics of the mechanically activated ZnO-TiO2 system was studied. Mixtures of ZnO and TiO2 powders were mechanically activated using a high-energy ball mill for different time intervals from 0 to 300 minutes. ...
Preparation and properties of BaTi1-xSnxO3 multilayered ceramics
(Journal of the European Ceramic Society, 2007)
BaTi1-xSnxO3 (BTS) powders, with x ranging from 0 to 0.15, were synthesized by solid-state reaction technique. The powders were pressed and sintered at 1370 degrees C. Obtained BTS ceramics were investigated by X-ray ...
