  • Biogenic silica–Metal Phosphate (Metal = Ca, Fe or Zn) nanocomposites: fabrication from rice husk and their biomedical applications
    Journal of Materials Science: Materials in Medicine, 2014
    Co-Authors: Jegan Athinarayanan, Vaiyapuri Subbarayan Periasamy, Ali Abdullah Alshatwi
    Abstract:

    In this investigation, we fabricated biogenic silica–Metal Phosphate nanocomposites (BSMPNs) using rice husk from agricultural waste as a silica source. The morphologies and dimensions of the synthesized nanocomposites were analyzed using transmission electron microscopy (TEM). Fourier-transform infrared spectroscopy results confirmed that Metal Phosphate crystals were formed with the biogenic silica. The X-ray diffraction patterns of the BSMPNs showed the presence of hexagonal calcium and iron Phosphate and orthorhombic zinc Phosphate nanoparticles embedded in the matrix of biogenic silica. The TEM images suggested that spherical and irregularly shaped tiny particles with dimensions between 50 and 100 nm were dispersed in the biogenic silica. The in vitro biological properties of the nanocomposites were studied by a cell viability assay and through the analysis of microscopy images. The cytocompatibility studies proved that the material was nontoxic and had excellent biocompatibility with human mesenchymal stem cells. The synthetic route for these nanocomposites is interesting and may be helpful in the fabrication of various novel silica-based composites and in the exploitation of eco-friendly agricultural biomass. Our results revealed that these nanocomposites can be used in bone tissue engineering.

  • topochemical synthesis of sodium Metal Phosphate olivines for sodium ion batteries
    ChemInform, 2011
    Co-Authors: T N Ramesh, Gianluigi A Botton, Linda F Nazar
    Abstract:

    Metastable olivine phases of crystalline Na[Mn1-xMx]PO4 (M: Fe, Ca, Mg; 0 ≤ x ≤ 0.5) are formed by solid state topotactic reactions of NH4 [Mn1-xMx]PO4·H2O and excess NaOAc (65—100 °C).

  • topochemical synthesis of sodium Metal Phosphate olivines for sodium ion batteries
    Chemistry of Materials, 2011
    Co-Authors: T N Ramesh, Gianluigi A Botton, Linda F Nazar
    Abstract:

    New metastable olivine phases of sodium Metal Phosphates, Na[Mn1–xMx]PO4 (M = Fe, Ca, Mg), nanorods are synthesized by a simple solid-state reaction at low temperature (≤100 °C) by means of a topotactic molten salt reaction that converts NH4[Mn1–xMx]PO4•H2O (M = Fe, Ca, Mg) to Na[Mn1–xMx]PO4. Their crystal structures are characterized via XRD Rietveld refinement and electron diffraction. A full range of solid solution behavior was observed for olivine Na1–xMn0.5Fe0.5PO4, in contrast to that of LiMPO4 (M = Fe, Mn) olivine materials, and is ascribed to ion size effects. The solid solution behavior of NaMn0.5Fe0.5PO4 was confirmed by electrochemical characterization.
