Neutron and X-ray scattering methods, developed by this research group, are used to study the structure and dynamics on nanometre and picosecond space/time scales. Adsorption, self-assembly at interfaces, polymers, the imitation of biomineralisation phenomena using “template” molecules and, most recently, the structure and denaturation of proteins at interfaces are current areas of interest. The insights gained are used to guide chemical synthesis in making new materials with interesting physicochemical properties.
Recent highlights include the production of robust titanium oxide films for water splitting and bio-degradation, and observation of isotope effects in hydrogen formation. The modelling of protein orientation at the air-water interface and interfacial protein denaturation thermodynamics as well as the first experiments showing the interfacial interaction of different milk proteins have succeeded. For emulsions, highlights are the design of co-surfactants which greatly change high internal phase emulsion properties, the first in situ experiments showing the effects of shear and the first synchrotron anomalous scattering experiments on surfactant-less emulsions.

Small angle neutron scattering (SANS) and ultra small angle neutron scattering (USANS) measurements have continued from high internal phase emulsions (90% aqueous phase/10% oil phase).
More about High Internal Phase Emulsions (SANS and USANS Analysis)
In a long-standing collaboration with Orica Australia Ltd, we have been looking at high internal phase emulsions with industrial applications.

A simple method has been developed to produce a stable, thin (~90 Å) oil film on the surface of pure water, suitable for direct measurements of the oil-water interface using ellipsometry, X-ray or neutron reflectometry, or other experimental methods.
Our work to preparate thin mesoporous TiO2 films (800 – 3000 Å), doped to provide a shift in the optical response and capture sunlight, has progressed.
