Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Properties of LiMn2O4 powders obtained by ultrasonic spray pyrolysis
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 2004)
LiMn2O4 powders were synthesized by ultrasonic spray pyrolysis. By varying the cooling conditions. two samples of powders were obtained: quenched in water (Q) and spontaneously cooled to room temperature (SC). The crystal ...
Screen printed BaTi1-xSnxO3 multilayer materials
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 2004)
BaTi1-xSnxO3 (BTS) piezoceramics with multilayer structure were prepared. The Sn concentration in the layers was changed from x=0.025 to 0.15. Thick films were screen-printed on alumina substrates electroded with Ag/Pd. ...
The influence of mechanical activation on the stoichiometry and defect structure of a sintered ZnO-Cr2O3 system / The influence of mechanical activation on the stoichiometry and defect structure of a sintered ZnO-Cr2O3 system
(Zurich : Trans Tech Publications, 2004)
Mixtures of starting ZnO and Cr2O3 powders in equimolar quantities were mechanically activated by grinding using a high energy vibro-mill for 0, 40 and 80 minutes. Qualitative X-ray diffraction analysis made after sintering ...
