Research Summary
grey-line-1.jpg

Development of new synthetic methods for the production of functional inorganic materials. Control of crystal chemistry and crystal form in one step synthesis for tuning the properties of complex materials including transition-metal oxide materials with properties that may be applied in electronic and catalytic applications and porous materials and with sorption properties. Understanding the crystallisation of solid-state materials using novel in situ probes, particularly time-resolved powder diffraction; characterisation of the solid-state using powder X-ray diffraction; the use of synchotron X-ray and neutron scattering methods at central facilities.
