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 ...
In vitro and in vivo investigation of collagen - C-60(OH)(24) interaction
(Trans Tech Publications Ltd., 2004)
In this paper both theoretical and experimental approach to a possible interaction between collagen hydrolyzate and fullerole C-60(OH)(24) have been considered. In vitro and in vivo experiments were performed. Based on ...
Enhancing Synthesis and Sintering of Zinc Titanate Using Mechanical Activation
(Progress in Advanced Materials and Processes, 2004)
Mechanical activation and sintering are used for obtaining zinc titanate, Zn2TiO4. Starting powder mixtures of ZnO and TiO2, in the molar ratio that is in accordance with the stoichiometry ofzinc titanate Zn2TiO4, were ...

(Belgrade : Institute of Technical Sciences of SASA, 2004)
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 ...
Processing and Mechanical Properties of Biphasic Calcium-Phosphate/Poly-L-Lactide Composite Biomaterials
(Trans Tech Publications, Ltd., 2004)
This study descripts processing of biphasic calcium-phosphate (BCP) and poly-L-lactide (PLLA) biocomposite implant material. The composite was obtained by mixing completely dissolved PLLA with granules of high crystalline ...
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. ...
Photoacoustic properties of single crystal NiO
(Progress in Advanced Materials and Processes: Proceedings of the 5th Jugoslav Materials Research Society, YUCOMAT, Herceg Novi, Yu, 15 - 19 September 2003, 2004)
Thermal and electron transport properties of NiO single crystal were determined using the photoacoustic frequency transmission technique. Thermal diffusivity, coefficient of carrier diffusion, their lifetime, and the front ...
Structural characterization of pure Na-nephelines synthesized by zeolite conversion route
(Journal of Physics and Chemistry of Solids, 2004)
Using the zeolite thermally induced transformation route and starting from Na-LTA, Na-FAU and Na-GIS zeolites as precursors, we synthesized pure sodium nephelines (ps-Ne) with Si/Al ratios between 1.0 and 1.5 (ps-NeLTA, ...
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 ...
