Reduction of the specific surface area of porous ZnO during sintering
(Čačak : Technical Faculty, 2007)
In this paper reduction of the specifice surface area of porous ZnO during sintering was analyzed. ZnO was sintered at temperatures from 673K to 1173K. Reduction of the specific surface area was observed as a function of ...
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 ...

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 ...
Investigation of sintering kinetics of ZnO by observing reduction of the specific surface area
(Belgrade : International Institute for the Science of Sintering, 2007)
Reduction of the specific surface area of porous ZnO during the sintering process was studied. ZnO powder was sintered at temperatures from 673 K to 1173 K. The decrease in the specific surface area was observed as a ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Belgrade : International Institute for the Science of Sintering, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
Evaluation of glassionomer cement application for permanent binding of prosthetic dentures
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Fixed dentures are created in order to rehabilitate the function of orofacial system, to
correct disordered interdental relation, as well as the relation between jaws and to do esthetic
correction. Binding of fixed ...
