Biphasic calcium phosphate coated with poly-d,l-lactide-co-glycolide biomaterial as a bone substitute
(Elsevier, 2007)
A calcium phosphate/poly-d,l-lactide-co-glycolide (BCP/DLPLG) composite biomaterial was synthesized in the shape of spherical granules (150–200 m) and nanostructured particles (30–40 nm) by an emulsification/evaporation ...
Influence of Urea as Homogeneous Precipitation Agent on Sonochemical Hydroxyapatite Synthesis
(Zurich : Trans Tech Publications, 2007)
The main purpose of the present work was to investigate the influence of urea concentration on hydroxyapatite (HAp) synthesis. Calcium nitrate and ammoniumdihydrogenphosphate were used as Ca and P sources. A homogeneous ...
Aerosol synthesis and characterization of nanostructured particles of Y3Al5O12:Ce3+ and Y2O3:Eu3+
(Belgrade : Association of the Chemical Engineers of Serbia, 2007)
Nanostructured YAG:Ce3+ and Y2O3:Eu3+ were synthesized by low temperature (320°C) aerosol synthesis-LTAS and high temperature (900°C) aerosol synthesis-HTAS, respectively. The synthesis included aerosol generation from a ...
Gd2O3:Eu System: Structural Study of the Influence of Luminescence Center Concentration
(Zurich : Trans Tech Publications, 2007)
In this paper, the influence of the Eu3+ center concentration on the structural and morphological properties of the Gd2O3 system obtained by Spray Pyrolysis have been studied. The processing route includes aerosol formation ...
Effect of ageing on optical and thermal properties of YBa2Cu3O7–δ
(International Journal of Materials Research, 2007)
Photoacoustic phase and amplitude spectra of YBa 2 Cu 3 O 7 – δ samples synthesised 18 years ago were measured and numerically analysed. The value of thermal diffusivity obtained on the aged samples was lower than the ...
The Influence of Milling Conditions on Mechanochemical Synthesis and Sintering of Zinc Titanate
(Kyiv : G. V. Kurdyumov Institute for Metal Physics of the National Academy of Sciences of Ukraine, 2006)
The aim of this work was an investigation of experimental conditions for mechanochemical synthesis and sintering of spinel zinc titanate (Zn2TiO4). Starting powder mixtures of zinc oxide and titan dioxide in the molar ...
Synthesis and characterization of biphasic calcium phosphate/poly-(DL-lactide-co-glycolide) biocomposite
(Current Research in Advanced Materials and Processes, 6th Conference of the Yugoslav-Materials-Research-Society, Sep 13-17, 2004, Herceg Novi, Montenegro, 2005)
In this paper we report the results on synthesis of a composite biomaterial based on biphasic calcium phosphate (BCP) and poly-(DL-lactide-co-glycolide) (DLPLG). Besides, we have investigated the influence of new synthesis ...
Microstructure and mechanical properties of hot-pressed hydroxyapatite/poly-L-lactide biomaterials
(Trans Tech Publications, Ltd., 2000)
Effects of the hot pressing parameters on the designing of structures and properties of hydroxyapatite/poly-L-lactide (HAp/PLLA) biocomposite blocks have been studied. Interdependences of temperature, pressure and time of ...
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 ...
The influence of tribophysical activation on non-isothermal sintering of BaTiO3 ceramics
(Durnten-Zurich : Trans Tech Publications Ltd., 2006)
In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., ...
