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
Designing Nano-Pore Architectures for High Power Battery Materials. In recent years there has been a steady increase in the popularity of portable electronic devices. Of the numerous battery systems available, alkaline MnO2/Zn cells are most commonly used to power these devices. However, as the device power requirements increase, so too does the demand on these cells to perform. Delta EMD, Australia, currently exports ~10% of the world's supply of MnO2 for these cells.

Electrochemistry of redox-active non-metal compounds. Unsaturated compounds of heavier non-metal elements can exist in multiple stable redox states. The interconversion is best assessed by electrochemical techniques, which can measure the energetics and the mechanism of the redox processes involved in both solution and solid state phases. Compounds to be studied will be prepared in the Canadian laboratories of the partner investigator.

The interconversion is best assessed by electrochemical techniques, which can measure the energetics and the mechanism of the redox processes involved in both solution and solid state phases. Compounds to be studied will be prepared in the Canadian laboratories of the partner investigator. The electrochemical and spectroelectrochemical properties will initially be investigated in Australia during the visit of the partner investigator to Monash University with follow up studies in both countries. The mutual skills of synthesis and electrochemistry in the Canadian-Australian laboratories are essential to the project.Read moreRead less
