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 gamma radiation on the glass transition of hydroxyapatite/poly L-lactide composite
(Trans Tech Publications, Ltd., 2007)
Hydroxyapatite/poly L-lactide (HAp/PLLA) is a composite biomaterial which has been widely utilized for substitution and reparation of the hard bone tissue. It is well known that gamma irradiation has been successfully ...
The Effect of Processing Parameters on Characteristics of Poly-L-Lactide Microspheres
(Research Trends in Contemporary Materials Science, 2007)
Biodegradable micro- and nanospheres made of poly-l-lactide (PLLA) are very potent drug or antigen delivery systems with inherent potential for drug and antigen targeting. The objective of this study is to formulate modified ...
Synthesis of ZnO and ZrO2 Powders by Mechanochemical Processing
(Research Trends in Contemporary Materials Science, 2007)
The ZnO and ZrO2 powders were prepared by mechanochemical processing and subsequent heat treatment of the starting powder of precursors mixture of ZnCl2 and Ca(OH)2, and ZrOCl2·8H2O and NaOH, respectively. Inert salt matrix, ...
