Investigation of ion-beam modified silicon by photoacoustic method
(IEEE, 2000)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs the modulating frequency ...
Analysis of in vivo substitution of bone tissue by HAp/PLLA composite biomaterial with PLLA of different molecular weights using FTIR spectroscopy
(Uetikon-Zuerich : Trans Tech Publ, 2000)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial with PLLA of 50,000 and 430,000 g/mole molecular weight was studied in vivo. The biocomposite with PLLA of both molecular weights was implanted into mice and ...
Nanoindentation of in situ polymers in hydroxyapatite/poly-L-lactide biocomposites
(Durnten-Zurich : Trans Tech Publications Ltd., 2006)
In order to obtain more accurate properties after compaction of hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite, high-resolution measurement of mechanical properties method is proposed to determine the properties of ...
Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Abingdon : Taylor & Francis Ltd., 2005)
Increasing demands on the quality of electronic ceramics requires a well-controlled correlation between particle morphology and processing conditions. Since mechanical activation is one of the methods for modification of ...
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 ...
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 ...
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 ...
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 ...
Aerosol synthesis of ruthenium doped ZnO fine particles
(Elsevier, 2004)
Zinc oxide, as n-type semiconducting nonstoichiometric metal oxide, with band gap of 3.2 eV, has wide application in optical and electronic devices (Rajeshwar et al., 2001), especially when composed of ultrafine crystallites ...
Dielectric and ferroelectric properties of BaTi1-xSnxO3 multilayered ceramics
(Research Trends in Contemporary Materials Science, 8th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS), Sep 04-08, 2006, Herceg Novi, Montenegro, 2007)
Multilayered BaTi1-xSnxO3 (BTS) ceramics with different Ti/Sn ratios were produced by pressing and sintering at 1420 degrees C for 2 hours. X-ray diffractometry, scanning electron microscopy and energy dispersive spectroscopy ...
