The experimental and theoretical investigation of Sm/Mg co-doped hydroxyapatites
Ala Hamd Hssain,Niyazi Bulut,Tankut Ates,Suleyman Koytepe,Ali Kuruçay,Hanifi Kebiroglu,Omer Kaygili +6 more
TL;DR: In this paper , an extensive experimental and theoretical analysis of Mg-doped hydroxyapatite (HAp) samples with additional Sm doping at varying amounts is presented, and all of these samples were investigated experimentally and theoretically by using the X-ray diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), Raman spectroscopic, differential thermal analysis (DTA), thermogravimetric analysis (TGA), in-vitro cell viability tests, and density functional theory (DFT) calculations.

Periodic ab initio study of structural and vibrational features of hexagonal hydroxyapatite Ca10(PO4)6(OH)2
TL;DR: The full B3LYP harmonic vibrational spectrum of HA at Gamma point has been computed and compares well with the available experimental IR and Raman data, Nevertheless, the presence of one negative frequency in the computed spectrum shows that, within the hexagonal symmetry imposed by the P6(3) group, the structure is a saddle point.
