Surface and Materials Science
- Metal oxides, hydroxides and nitrides in catalysis, semiconductor materials,absorbents and refractories.
- Synchrotron radiation and applications in surface and materials science.
- Alumina microstructure and the impacts of alumina properties in aluminium reduction technology.
- Silicon carbide based refractories for aluminium reduction technology
Aluminium oxides are being studied particularly in relation to thermal effects on microstructure and how these develop during calcination. This is of particular importance in the use of aluminas in catalysis and as absorbents. The work is carried out in collaboration with several external sponsors.
Mixed transitional metal oxides and oxynitrides are being investigated in terms of their electronic and magnetic properties. Metal/metal oxide nanoparticles grown within oxide layers are being investigated in terms of their formation mechanism and magnetic sensing capabilities.
Silicon Nitride bonded and Silicon carbide bonded silicon carbide refractories are being developed as next generation refractories for the sidewalls of molten salt electrolysis cells. These materials show very good performance in terms of resistance to corrosion and gas attack, but higher density, lower porosity materials are key to life extension. Novel infiltration and densification technologies are being examined.

- Time-of-flight SIMS of oxide surfaces
There is a crucial need to understand the structure and stability of oxide and hydroxide films and layered inorganic oxides/hydroxides. This work will use TOF-SIMS to examine the relationship between surface structure and secondary ions formed by desorption from these surfaces, after treatment with various labelling adsorbates and intercalated species.
