My research involves using solid state NMR techniques on a range of materials, mainly concentrating on disordered materials such as glasses. This involves a multinuclear approach, looking at both spin-½ and quadrupolar nuclei at a range of fields from 2.3 T up to 14.1 T.


J Couplings in Phosphate Glasses using the REINE pulse sequence

My current research involves utilising the REINE (Refocused INADEQUATE spin-Echo) (Phys. Chem. Chem. Phys. 2007, 9, 92-103) pulse sequence using 31P NMR on phosphate based glasses. From this technique distributions of J couplings present due to the large disorder throughout the glass structure can be determined. This is to be extended to series of glasses with the ultimate aim of obtaining better understanding of glass bonding in order to help build up a model of phosphate glass structure.


Mullites

NMR is also a widely used tool in the characterisation of ceramics. Owing to their favourable properties and their ability to incorporate large amounts of doping ions, determining the atomic structure of the aluminosilicate material mullite has been important, with NMR a vital tool. In my research various mullite structures are to be investigated using a multinuclear approach with a range of NMR experiments. With the overall aim to determine how doping with boron ions affects the mullite aluminosilicate structure.
