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.

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 the subsequent stability of the pigment will allow advances in processing and consequently improved final products. The potential growth in market share, by improved product performance, is in excess of $50M pa.Read moreRead less
Improving Energy Efficiency through Cool Polymers in Building Materials. The advantages of using cool polymers in industrial applications such as building materials are significant. Cooler buildings are a positive contribution to our global environment with reductions in urban heat and smog through energy efficiency. Moreover, by reducing the overall temperature of the surface coating through inclusion and optimization of IR-reflective pigments, this should lead to polymers which are more durabl ....Improving Energy Efficiency through Cool Polymers in Building Materials. The advantages of using cool polymers in industrial applications such as building materials are significant. Cooler buildings are a positive contribution to our global environment with reductions in urban heat and smog through energy efficiency. Moreover, by reducing the overall temperature of the surface coating through inclusion and optimization of IR-reflective pigments, this should lead to polymers which are more durable when exposed in exterior environments. It is anticipated that the results from this work will have direct impact on the Australian paint market and potentially the commercial and residential building industries of Australia, combined with obvious economic benefits.Read moreRead less
Performance Chemistry of Thermoset Surface Coatings. Surface coatings employed in the COLORBOND® range of pre-painted steel products are remarkable materials that are warranted against fading, peeling and cracking for 25 years. Unfortunately, the desired durability can never be uniform across all applications and performance failures do occur and are costly. Classic durability testing often provides misleading information. This project aims to develop a sound mechanistic model for polyester-is ....Performance Chemistry of Thermoset Surface Coatings. Surface coatings employed in the COLORBOND® range of pre-painted steel products are remarkable materials that are warranted against fading, peeling and cracking for 25 years. Unfortunately, the desired durability can never be uniform across all applications and performance failures do occur and are costly. Classic durability testing often provides misleading information. This project aims to develop a sound mechanistic model for polyester-isocyanate performance chemistry and to develop strategies for 'superdurable polyester' formulations based on these findings. This research will provide recommendations to BHP Coated Steel Australia on adoption of isocyanate based technology in the COLORBOND® range of products.Read moreRead less
Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smal ....Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smaller systems at source. This will enable greater reliability of localised treatment, which will reduce pumping requirements and decrease both cost and carbon emissions. Read moreRead less
Understanding Electron Transfer through Surface Bound Rigid Molecular Constructs: From Fundamental Studies to New Sensing and Photovoltaic Applications. Electron transfer is not only a vital process in biological systems but is the cornerstone of the new generation of nanoscale devices such as molecular electronics, photovoltaic devices and biosensors. For most applications electron transfer occurs close to a surface but the influence of the surface is not well understood. This project aims ....Understanding Electron Transfer through Surface Bound Rigid Molecular Constructs: From Fundamental Studies to New Sensing and Photovoltaic Applications. Electron transfer is not only a vital process in biological systems but is the cornerstone of the new generation of nanoscale devices such as molecular electronics, photovoltaic devices and biosensors. For most applications electron transfer occurs close to a surface but the influence of the surface is not well understood. This project aims to increase our understanding of the role of surfaces on the electron transfer behaviour using a novel range of rigid 'molecular wires'. The knowledge gained will be exploited in the development of novel biosensors for environmental and health monitoring and new highly efficient solar cells for energy conversion.Read moreRead less
Greatly improved rectification by molecular diodes. Society has already seen dramatic benefits from microtechnology, which has made possible most of the devices that we take for granted. The limits of miniaturisation using current technology are rapidly being reached, and the next stage is in the realm of nanotechnology. The goal of the field known as molecular electronics is to reach the point where electronic components are composed of single molecules or single molecular layers. In this fi ....Greatly improved rectification by molecular diodes. Society has already seen dramatic benefits from microtechnology, which has made possible most of the devices that we take for granted. The limits of miniaturisation using current technology are rapidly being reached, and the next stage is in the realm of nanotechnology. The goal of the field known as molecular electronics is to reach the point where electronic components are composed of single molecules or single molecular layers. In this field the smallest active component is the molecular diode, and this project is focussed on achieving practical performance from molecular diodes, as a crucial first step in achieving miniaturisation far beyond anything now possible.Read moreRead less
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
