This project aims to develop a robust time scale for the known aboriginal rock art sequence in the Kimberley, Western Australia (WA). The project will use new knowledge of complex processes on sandstone surfaces across the north Kimberley, and an innovative combination of four scientific dating methods developed through our earlier work. The project expects to provide a well-dated sequence for Kimberley rock art based on replication of results, confirmation across different methods, and a large interdisciplinary data set. The project will allow rigorous analysis of the relationship between dating results and rock art styles that has not previously been possible, and give new insights into Australia’s deep indigenous heritage. This will have a significant impact for future efforts in rock art conservation, and lay a foundation for cultural tourism, with important benefits for the local economy and health of regional indigenous communities.Read moreRead less

It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pi ....Enhanced pigment weathering resistance by coating with high dielectric ceramic. The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pigment regrind stage. The research will investigate the development of a highly durable dry-coated pigment utilising a novel high dielectric coating. This development has the potential to ensure the partner company's future competitiveness through reduced processing costs and improved product performance.Read moreRead less
Functional nano-porous metal membranes for sustainable separation in industrial processes. There are many waste streams that need to be purified which degrade conventional membranes.

There are many waste streams that need to be purified which degrade conventional membranes. This project with local company AMS aims to develop nano-porous metal membranes as a sustainable alternative to conventional membrane materials. Highly porous and ultra-thin metal membrane sheets with narrowly distributed nano-scale pores will be fabricated and functionalised to purify both model and industrial wastewaters. This intends to lead to the production of stronger, more versatile and chemically stable membrane materials that will exhibit longer lifespan and performance. The most significant outcome is expected to be low cost metal alloys with pores below the current 100 nm benchmark and assess their thermo-chemical stability.Read moreRead less

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.
