Microstructure and dielectric properties of BaTiO3 doped with Er2O3, Yb2O3 and Ho 2O3
(Faenza : ISTEC-CNR, 2008)
Doped barium-titanate ceramic is attracting much interest for its application as resistors with a positive temperature coefficient of resistivity (PTCR), multilayer ceramic capacitors (MLCC), thermal sensors etc. In this ...
Tailored preparation of nano and micro composites as new controlled bone drug delivery systems
(Faenza : ISTEC-CNR, 2009)
Method of homogenous sonochemical principle for obtaining controlled forms of micro/nano particles of desired shapes, size and distribution, and solvent/nonsolvent method for obtaining spherical particles of polymer or ...

(Belgrade : Institute of Technical Sciences of SASA, 2009)
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 ...
Structural and dielectric properties of BaTi1-xSnxO3 ceramics
(Recent Developments in Advanced Materials and Processes, 7th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS), Sep 12-16, 2005, Herceg Novi, Montenegro, 2006)
BaTi1-xSnO3 (BTS) powders, with x ranging from 0 to 1, were synthesized by solid-state reaction technique. The powders were pressed into pellets and sintered at 1370 and 1420 T. The structural characterization of sintered ...
Aktivnost alkalne fosfataze u kosti nakon implantacije nanočestičnog kalcijum-kobalt hidroksiapatita
(Beograd : Institut tehničkih nauka, 2009)
Istraživanje je sprovedeno sa ciljem da se dokaže aktivnost alkalne fosfataze, lokalizovane u dekalcifikovanoj kosti, uzete sa leve strane mandibule pacova, u kojoj je arteficijalno napravljen defekt i implantiran nano ...
Dielectric properties of BaTiO3 doped with Er203 and Yb203 based on intergranular contacts model
(Hoboken, NJ : John Wiley & Sons, 2009)
Taking into account that microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of these material, in this study, the model of ...
Primena Ramanove spektroskopije u proučavanju mehaničke aktivacije BaTiO3
(Beograd : Institut tehničkih nauka SANU, 2006)
U ovom radu su ispitivane strukturne promene BaTiO3 tokom mehaničke aktivacije. Kao početni prah, korišćen je BaTiO3 (Aldrich) prah čistoće 99.9%. Mehanička aktivacija ovog praha izvršena je mlevenjem u visokoenergetskom ...
Electrical properties of mechanochemicaly activated cordierite ceramics
(Kiev, 2009)
Three-component oxide mixture was prepared containing MgO+Al2O3+SiO2 in a 2:2:5 ratio with addition of 10% Bi203. Mixtures were mechanically activated in range from 5 to 240 minutes in a mill with ceramic balls, and sintered ...
Influence of the HAp ratio on the thermodynamic and kinetic parameters of PDMS/HAp composites cross-linking
(Contemporary Studies in Advanced Materials and Processes, 4th Yugoslav-Materials-Research-Society Conference, Sep 10-14, 2001, Herceg Novi, Yugoslavia, 2003)
Injectable and gas-permeable composite cements, polydimethylsiloxane/hydroxyapatite (PDMS/HAp), were synthesized using bi-component polysiloxane precursors (RTV-A and RTV-B), which react by hydrosilylation, and different ...
