Glass-ceramics containing only apatite and wollastonite crystals were produced in the system MgO-CaO-SiO2-P2O5-F by the melt casting process. The bioactivity of the glass-ceramics was determined by immersing the glass-ceramics in a simulated body fluid (SBF) and by assessing the resulting apatite formation on the free surface after various immersion durations. A 12-mu m-thick apatite layer formed on the surface of the glass-ceramic containing only apatite crystals after 20 days immersion in SBF. However, the thickness of the apatite layer formed on the surface of the glass-ceramic containing apatite and wollastonite crystals was 1 mu m. Results have shown that the bioactivity of glass-ceramic depends strongly on the type of crystal(s) developed during the glass-ceramic process and their proportion in the glassy matrix.

Ion beam synthesized lummescent Si nanocrystals embedded in SO2 films and the role of damage on nucleation during annealing
Mayandi, J.; Finstad, T. G.; Foss, S.; Thogersen, A.; Serincan, U.; Turan, Raşit (Elsevier BV, 2007-08-05)
Si nanocrystals in thermal oxide films (similar to 250 nm) were fabricated by 100 keV Si ion implantation followed by high temperature annealing. Two different doses were compared after annealing at 1050 degrees C for 2 h. A sample implanted with a dose of 1 x 10(17) cm(-2) shows a broad photo luminescence peak centered around 880 nm after annealing. A dose of 5 x 10(16) cm(-2) yields a considerable blue shift of about 100 nm relative to the higher dose as well as a reduction in intensity. Transmission elec...
Refractive index, static dielectric constant, energy band gap and oscillator parameters of Ga2SeS single crystals
Qasrawi, A. F.; Hasanlı, Nızamı (Wiley, 2007-09-01)
The optical properties of Bridgman method grown Ga2SeS crystals have been investigated by means of room-temperature transmittance and reflectance spectral analysis. The optical data have revealed direct and indirect allowed transition band gaps of 2.49 and 2.10 eV, respectively. The room-temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as...
Energy band gap and oscillator parameters of Ga4Se3S single crystals
Qasrawi, A. F.; Hasanlı, Nızamı (Elsevier BV, 2007-06-01)
The optical properties of the Bridgman method grown Ga4Se3S crystals have been investigated by means of room temperature, transmittance and reflectance spectral analysis. The optical data have revealed an indirect allowed transition band gap of 2.08 eV. The room temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as 21.08 and 3.85 eV, 6.48 a...
Optoelectronic properties of Tl3InSe4 single crystals
QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Informa UK Limited, 2010-01-01)
The crystal structure, temperature-dependent electrical conductivity, Hall coefficient, current-voltage characteristics, absorption spectra and temperature- and illumination-dependent photoconductivity of Tl3InSe4 single crystals were investigated. Tl3InSe4 crystallises in a body-centred lattice with tetragonal symmetry and belongs to the space group [image omitted]. The crystals are extrinsic p-type semiconductors and exhibit a conductivity conversion from p- to n-type at a critical temperature, Tc, of 283...
Density functional and dynamics study of the dissociative adsorption of hydrogen on Mg (0001) surface
Kecik, D.; Aydınol, Mehmet Kadri (Elsevier BV, 2009-01-15)
A first principles study is performed to investigate the adsorption characteristics of hydrogen on magnesium surface. Substitutional and on-surface adsorption energies are calculated for Mg (0001) surface alloyed with the selected elements. To further analyze the hydrogen-magnesium interaction, first principles molecular dynamics method is used which simulates the behavior of H-2 at the surface. Also, charge density differences of substitutionally doped surface configurations were illustrated. Accordingly, ...
