Electronic and Optical Properties of Doped Titanium Dioxide. Titanium dioxide, is widely used as a white pigment, owing to its high refractive index, second, only after diamond. Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify ....Electronic and Optical Properties of Doped Titanium Dioxide.

Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify the specific electronic cause of the yellowing process, the nature of the Al defect,it's effect on the electronic structure of rutile, and the electronic perturbations that may occur when other dopants are used.Read moreRead less

Better Batteries via Controlling the Properties of Electrolytic Manganese Dioxide. Physical properties of electrolytic manganese dioxide (EMD) such as crystal structure, morphology and electrochemical characteristics determine its usefulness in alkaline batteries.

Physical properties of electrolytic manganese dioxide (EMD) such as crystal structure, morphology and electrochemical characteristics determine its usefulness in alkaline batteries. However, the relationship between these parameters is not well understood. This APAI project will attempt to address these shortcomings in the current understanding of the production process by focussing on the relationships between fundamental physical, chemical and electrochemical properties of EMD.

Designer Surfactants for Creation of Emulsion Properties. We propose new approaches to the design of surfactants for stabilising water in oil emulsions. New block copolymer surfactants may be "tailored" for head group structure and a pre-chosen hydrophilic/lipophilic balance at the oil-water interface using the Australian developed RAFT polymer synthesis method and polymeric inorganic species. The proposers have an extensive background in these areas.

The proposers have an extensive background in these areas.
X-ray and neutron scattering techniques, developed by us, allow the interfacial structure of the surfactant to be found and the intellectual "loop" closed in the design process. Preliminary screening will be done using the surface balance and bulk emulsion synthesis.Read moreRead less

Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mesoscale structure in emulsion formulation, as well as the rheology and stability of emulsion preparations. To do this we plan to use mixed surfactant systems and to study intersurfactant synergic effects on the structure and fluidity of the interfacial material. We believe that the proposed work is unique and that the outcomes will be scientifically novel and also valuable for Australian industry.Read moreRead less
