Tiwest has a major impact on the Western Australian economy with more than 700 full time and contract jobs, export earnings of $400M (in 2004) and regular incomes for an estimated 500 businesses. The current wet pigment particle coating process, to ensure ease of handling and longevity, is a major cost. An optimised pigment dry-coating process would ensure Tiwest's competitiveness through reduced processing costs and improved performance. This development has the potential to increase Tiwest's profitability by 10%.Read moreRead less
The recovery of Cu from chalcopyrite-pyrite containing concentrates, ores and tailings. Chalcopyrite, a major source of Cu, is often associated in ores with the valueless mineral pyrite. The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;
- leaching of Cu from ores and tailing in a heap leach ....The recovery of Cu from chalcopyrite-pyrite containing concentrates, ores and tailings. Chalcopyrite, a major source of Cu, is often associated in ores with the valueless mineral pyrite. The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;
- leaching of Cu from ores and tailing in a heap leach environment and
- leaching of Cu in a concentrated chalcopyrite-pyrite reactor environment.
These aims will be achieved via an integrated surface-solution speciation approach allowing the manipulation of surface properties.

New insulins for the improved management of diabetes. The prevalence of diabetes has increased dramatically over the past few decades and now this condition is widely considered the world’s fastest growing disease. New insulins with improved pharmacological and storage properties are desperately needed, and this project will work on chemical synthesis enabling designer insulins to be prepared for improved management of diabetes.
Surface engineering of oriented nano-layers for performance control. This research project will deliver knowledge on how to graft oriented, self assembled films from a surface, develop structure-property relationships at a nano-scale, develop a means to control these properties and develop characterization techniques at nano-scales. This research project, if successful, will deliver the ability to tailor the properties of a surface in a manner and over a range of properties that is not even cont ....Surface engineering of oriented nano-layers for performance control. This research project will deliver knowledge on how to graft oriented, self assembled films from a surface, develop structure-property relationships at a nano-scale, develop a means to control these properties and develop characterization techniques at nano-scales. This research project, if successful, will deliver the ability to tailor the properties of a surface in a manner and over a range of properties that is not even contemplated today.
In addition to the scientific benefits, there are also immediate commercial applications in Australia and worldwide for ophthalmic products (e.g. anti-fog and easy to clean lenses), if the balance of properties can be obtained.

XeroCoat is commercialising nanotechnology research out of UQ's Physics department. XeroCoat has received much local and international interest in its signature product 'XeroCoat'. The company is rapidly expanding and has established new research facilities with production facilities to be set-up. This will result in high technology, employment growth for Australia. Links with Flinders could see expansion into SA. The company operates in 'Sol-Gel' nanotechnology, which has huge global, academic and commercial interest. However in Australia this technology has only been serviced by Flinders, ANSTO and ANSTO's spin-out company Ceramisphere. The project will help to build a new Australian high tech industry in sol-gel nanotechnology.Read moreRead less
Highly Crosslinked Poly(urea-co-urethane) Copolymer Concrete Floor Coatings. Recently developed, poly(urea-co-urethane) concrete floor screeds are used, in the construction industry, to provide protection against corrosive chemicals and abrasive wear; properties unmatched by other commercial floor treatments. Significantly such material has reduced environmental emissions and toxicity hazards.

Recently developed, poly(urea-co-urethane) concrete floor screeds are used, in the construction industry, to provide protection against corrosive chemicals and abrasive wear; properties unmatched by other commercial floor treatments. Significantly such material has reduced environmental emissions and toxicity hazards. Factors, which affect the cure and performance of poly(urea-co-urethane) flooring materials will now be studied, including the uncontrolled release of carbon dioxide, which results in sporadic blister formation, leading to the on-site product failures that have severely limited the product's commercial growth. Clear understanding of cure chemistry and adhesion will be established for the first, allowing for the products further development.Read moreRead less

Polymers are used widely in the mineral processing industry to alter mineral surfaces, often selectively. In spite of this, there remains a gap in our understanding of how polymers interact with mineral surfaces and how their surface structure affects the mineral surface properties. The aim of this project is to fill this gap by performing fundamental research on adsorbed polymer structure and properties, coupled with applied research on real mineral ores from a number of mineral companies. The combination of fundamental and applied research makes this project unique in the study of polymers at mineral interfaces, and will enable us to solve real processing problems through a rational choice of polymers for a given application.Read moreRead less
