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 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
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. 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 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

The potential growth in market share for the Australian pigment industry is in excess of $50M pa.Read moreRead less
Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of ....Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of the road asset exceeds $106,000 million. Thus providing satisfactory tough protective shield on asphalt pavements that locks out destructive elements and provide long-term protection is of enormous economic importance and national/community benefit.Read moreRead less
Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously gen ....Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously generate nitric oxide, but not for extended periods of time. This project’s approach is significant because it avoids bacterial resistance to the nitric oxide treatment. Applications of this technology may include removing biofilms from environments such as water filtration devices and consumable medical surfaces.Read moreRead less
