Research Interests

The use of solution and solid state nuclear magnetic resonance (NMR) spectroscopy to study structure and dynamics at the molecular level. Prof. Hawkes uses NMR methods for problem solving in a wide range of materials, chemical and biochemical areas. Current instrumentation available includes the new Oxford Instruments Hypersense for dynamic nuclear polarization (DNP) experiments, and multinuclear 9.4 T (400 MHz) and 14.1 T (600 MHz) spectrometers for both solution and solid state work.

Current research topics include:

·         the use of high field solid state NMR to study structure and speciation in bioactive and biocompatible phosphate glasses and ceramics, which have potential use as bone implant material

·        the use of high field solid state NMR to study structure and reactivity in phosphosilicate glasses which have potential use as restorative dental materials

·        the use of high field solid state NMR to study structure and speciation in highly conducting lithium phosphate glasses doped with paramagnetic ions

·        exploring the use of DNP sensitivity enhancement in application to 15N NMR (low molecular mass compounds), 29Si NMR (solution speciation of silicates), and 13C NMR (derivatised fullerenes and carbon nanotubes)

·       the use of high field solution state NMR to determine compositions and molecular structures in extracts of therapeutic medicinal plants
