BSc (Hons), PhD (Physics)
Professor in Physics
Projects on materials for hydrogen storage, hydrogen storage for off-grid power supply, fundamental aspects of the interaction of hydrogen with materials, quantum mechanics of high-energy neutron scattering from light elements, magnetic properties of materials, interaction of CO2 and other gases with nanostructured carbons including coal, sensors based on graphene. Techniques used include neutron scattering (powder diffraction, deep-inelastic scattering), high-energy X-ray powder diffraction, high-pressure methods for determining uptake of hydrogen and other gases by materials, cryogenic magnetometry In-house facilities for materials preparation (ball mills, glovebox, furnaces), measurement of hydrogen uptake to 200 MPa (many instruments), thermal desorption spectroscopy, high-energy X-ray diffraction under gas pressures to 70 MPa, conduction and magnetic properties to 8.5 tesla and 4 kelvin.
