Summary
Mobile weather radar system for advanced environmental monitoring and modelling. High spatial and temporal resolution weather radar data on wind and precipitation will translate to significant environmental model advances. Australian researchers will undertake model validation studies on precipitation, dust storm, and flood prediction under a wider range of environmental conditions and in greater detail than currently possible.
Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high ....Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high quality long-term records are sparse and little investigated. This project will also underpin the outstanding universal value of the Fraser Island World Heritage Area which is based on the area being the world's largest sand island, but for which scientific understanding of the sand dunes is remarkably poor.Read moreRead less

Summary
Aquifers as climate logs: untangling replenishment mechanisms. This project aims to develop methods that use environmental tracers to provide detailed information about groundwater ages and relate the age structure of groundwater systems to past climatic conditions. The impacts of climate change on groundwater resources is an important question in hydrogeological studies. The age of groundwater within an aquifer represents a detailed log of past recharge events. The project will generate methods ....Aquifers as climate logs: untangling replenishment mechanisms. This project aims to develop methods that use environmental tracers to provide detailed information about groundwater ages and relate the age structure of groundwater systems to past climatic conditions. The impacts of climate change on groundwater resources is an important question in hydrogeological studies. The age of groundwater within an aquifer represents a detailed log of past recharge events. The project will generate methods for assessing the past history of groundwater resources, and provide insight into the viability of groundwater in the future. This will improve understanding of how groundwater resources will behave under a changing climate.Read moreRead less
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
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.
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.

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
Quantitative metrics for determining aquifer ecosystem state. Clean groundwater comes from dirty surface water by way of biological purification. This project will develop quantitative ways to assess groundwater ecosystems to ensure the sustainable extraction of water and maintenance of these crucial ecosystems.
Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little ....Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less
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.

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
