Research

The seemingly simple inorganic component of bone and teeth--hydroxylapatite, Ca₅(PO₄)₃OH--has occupied our attention for the last decade.  We are intrigued by the fact that a great variety of ions can replace the ions in apatite, which leads to applications such as remediation of heavy metals, ion-exchange, nuclear waste encapsulation, phosphors, and so on.  We have prepared apatites containing different divalent cations of elements such as Sr, Ba, Pb, and Cd and have explored the structure of these using solid state NMR and infrared spectroscopy, as well as X-ray diffraction.  Our most recent focus has been on the substitution of the carbonate and sulfate ions for phosphate or hydroxide and the presence of water in the structural channels that are important to the biological activity of these compounds.  Currently we are attempting to identify the location of various substituting anions in the structure of apatite, with the hope of understanding how composition and structure of the substituent may affect its location.
