Flotation mechanisms of calcareous phosphates ores, and in particular the reaction between phosphoric acid fluorapatite have still to be elucidated. In present work, variations carbonated hydroxyfluorapatite (C-HFAp) contact with various concentrations were studied using ex-situ in-situ techniques, namely Raman Infrared spectroscopy, X-Ray diffraction (XRD) Scanning Electron microscopy (SEM). s...

Mn doped ZnO nanocrystals were prepared by co-precipitation route sintered at 450 °C temperature. XRD results indicate that the samples having hexagonal (wurtzite) structure. From X-ray data it is found that the lattice parameters increase with increasing Mn concentration. The X-ray density decreases with increasing Mn concentration of Zn 1-x Mnx O nanocrystals. It indicates that the Mn...

We derive an analytical expression for the broadening of a Gaussian input pulse in an arbitrary linear slow light medium. The expression consists of two terms, one corresponding to amplitude broadening (low-pass filtering of the pulse bandwidth) and another corresponding to phase broadening (phase dispersion around the resonance). It is shown that for a Lorentzian gain profile, the amplitude br...
