Optimisation of pigment coating surface treatments. Control and optimisation of surface coatings in pigment processing will lead to improved production efficiency and quality. In pigment processing, technology developed in this project may not only save millions of dollars in increased production efficiency but also lead to improved pigment optical performance in pigment applications such as paints, plastics and pharmaceuticals.
STABILISATION OF TITANIA PIGMENTS FOR IMPROVED WATER-BASED PAINT APPLICATIONS. This project aims to improve the stability and optical properties of titania pigments in water-based paints. Tailored dispersing agents will be used to stabilise pigments in paints in both the wet and dry state. Enhanced understanding of the dispersing agents interaction with the titania pigment surface and the subsequent stability of the pigment in dry paint films will allow advances in water-based paint stability.

Tailored dispersing agents will be used to stabilise pigments in paints in both the wet and dry state. Enhanced understanding of the dispersing agents interaction with the titania pigment surface and the subsequent stability of the pigment in dry paint films will allow advances in water-based paint stability. This understanding facilitates continued movement away from solvent-based paints required by environmental and health legislation. The potential growth in market share for the Australian pigment industry is in excess of $50M pa.Read moreRead less
Stabilisation of Titania Pigment Slurries During Processing. This project aims to improve the stabilisation properties of titania pigment slurries during production. Current polyphosphate dispersants used by Tiwest are unstable under processing conditions. Tailored, robust dispersing reagents will therefore be investigated in order to provide improved stabilisation of pigments during processing. Enhanced understanding of the dispersing reagents interaction with the titania pigment surface and th ....Stabilisation of Titania Pigment Slurries During Processing.

Development of Dry Coated Pigment Particles: Durability and Dispersion. Tiwest is the only business in the world that mines, separates, refines and manufactures titanium dioxide products in one region. 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 ....Development of Dry Coated Pigment Particles: Durability and Dispersion.

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 effect of de-gassing on the dispersion and stability of emulsions and colloidal solutions. Although it is widely accepted that oil and water will not mix, the reverse has recently been found to occur (by the applicant) under the unusual conditions of complete de-gassing. This discovery has opened up new areas for investigation and for the development of new processes and products. Hydrocarbon oils and hydrophobic powders can now be readily dispersed in water without the use of additives. Ho ....The effect of de-gassing on the dispersion and stability of emulsions and colloidal solutions.

This discovery has opened up new areas for investigation and for the development of new processes and products. Hydrocarbon oils and hydrophobic powders can now be readily dispersed in water without the use of additives. However, the mechanisms involved have not yet been elucidated and it is the aim of this project to understand the process and develop potential commercial applications.Read moreRead less

Summary
Oxidative stress bioanalytical facility. The primary national benefit of this application is that it will provide a currently unavailable, state-of-the-art facility for Australian scientists to define precisely how changes in cellular redox state contribute to biological processes relevant to health and diseases. The facility will uniquely complement, and in many cases integrate with existing facilities in this area of research in Australia. It will act as a platform for major national and inter ....Oxidative stress bioanalytical facility. The primary national benefit of this application is that it will provide a currently unavailable, state-of-the-art facility for Australian scientists to define precisely how changes in cellular redox state contribute to biological processes relevant to health and diseases. The facility will uniquely complement, and in many cases integrate with existing facilities in this area of research in Australia. It will act as a platform for major national and international research collaborations, develop cutting-edge technology and unique local skills, and contribute to Australia maintaining a leading position in redox-related research in biology and medicine. In doing so, the facility will increase the likelihood of gaining future, value-adding funding.Read moreRead less
An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses ....An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses of N, P from fertilisers will be investigated. The major outcome of this research will be effective and inexpensive procedures for reducing eutrophication due to N, P from waste water and fertilisers.Read moreRead less
