Unlocking the secrets of the groundwater cycle using Si and Li isotopes. This project aims to determine how non-conventional lithium and silicon isotopes can be used to understand groundwater processes using an innovative source-to-target approach. The project aims to apply these isotope tracers to trace the water cycle within a well constrained system: an island aquifer with a dense borefield which has been analysed using traditional isotopic techniques.

This project aims to determine how non-conventional lithium and silicon isotopes can be used to understand groundwater processes using an innovative source-to-target approach. The project aims to apply these isotope tracers to trace the water cycle within a well constrained system: an island aquifer with a dense borefield which has been analysed using traditional isotopic techniques. Supporting hydrochemical data will be used to determine the relationship of the isotopes with environmental processes. The project impact will be the development of new methods to help understand our groundwater resource. The improved process understanding will be translated to groundwater management in general. The projects' focus on carbonate aquifer systems typical of coastal regions of southern, eastern and western Australia will have relevance to groundwater management in urban areas such as Perth and in rural areas for tourism and viticulture, and for management of natural resources in National Parks.Read moreRead less
Resilience in biogeochemical pathways along a catchment-to-coast continuum. Aquatic systems have degraded more in the past 50 years than any other time in history. Global pressures are further threatening their sustainability, but their complexity makes it difficult to understand how they are responding. This project will combine numerous state-of-the-art approaches to unravel pathways that shape their response.

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.
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.
Energetics and dynamics of solvated biologically relevant molecules using liquid microjet and ion imaging technologies. The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule. Many experiments have informed u ....Energetics and dynamics of solvated biologically relevant molecules using liquid microjet and ion imaging technologies. The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule. Many experiments have informed us about the strength of the bonds, others have told us where the bonds occur. This project will provide both pieces of information for the first time, allowing us to better understand, and therefore control, biological function. This work will assist in the development of new biotechnology processes, especially in the emerging area of proteomics.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.
