Carbon nanotube fluidic channels for desalination - interplay of nanoscale confinement and electrostatics. Tiny tubes of carbon, ten thousand times smaller than human hair, allow water to pass through at extraordinary speed. This project aims to understand and improve their salt rejection properties using comprehensive experimental and theoretical approaches. This will provide the impetus and knowledge for developing advanced membranes for desalination
Groundwater flow age distributions: Understanding open pit mine hydrology. This project aims to improve the estimation of the age of groundwater. Understanding groundwater age is critical for sustainable management and environmental tracers are increasingly used for this purpose. However, groundwater samples are inevitably mixtures of water of different ages.

This project aims to improve the estimation of the age of groundwater. Understanding groundwater age is critical for sustainable management and environmental tracers are increasingly used for this purpose. However, groundwater samples are inevitably mixtures of water of different ages. Since for most tracers the relationship between tracer concentration and age is not linear, different tracers can produce different mean ages for the sample. This project aims to determine whether it is possible to determine moments of the groundwater age distributions from measurements made with different environmental tracers. The project also aims to examine whether the degree of heterogeneity within the aquifer can be determined from the disparity between ages obtained with different tracers. This project aims to tackle the largest problem with using groundwater chemistry to estimate water age – that mixing processes in the subsurface are never known. Solving this problem will allow much more accurate estimates of groundwater velocity and aquifer recharge rates. The groundwater industry contributes an estimated $6.8 billion per annum to the Australian economy, and this project will contribute to the sustainable management of the groundwater resource.Read moreRead less
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

Transistor-based sensor technology for fast, reliable and accurate in situ monitoring of recycled wastewater. Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand. The greatest community and industry concerns over recycled water are quality assurance and relative cost. Ensuring quality requires monitoring of contaminants, yet no single real-time technology exists to measure the myriad of potential con ....Transistor-based sensor technology for fast, reliable and accurate in situ monitoring of recycled wastewater. Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand. The greatest community and industry concerns over recycled water are quality assurance and relative cost. Ensuring quality requires monitoring of contaminants, yet no single real-time technology exists to measure the myriad of potential contaminants. This project will develop technology using AlGaN/GaN-based transistors, sensitised to different contaminants, enabling multi-analyte real-time sensor arrays. In situ monitoring systems based on such arrays will be fast, accurate, reliable, low-cost, and applicable to a broad variety of water recycling projects.Read moreRead less

This facility will improve our ability to forecast environmental responses to future climate change, and help Australia manage current threats to its biodiversity. Furthermore, this research will increase the ability to identify crude oil sources, to the benefit of petroleum exploration in Australia. This facility will also contribute to an improved understanding of controls on water quality and will help to protect our precious freshwater resources, already under intense pressure from climate change. Importantly, this project will enable students and young professionals to be trained in state-of-the-art technology, leading to quality scientists ready for employment in industry.

Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less

Australian national facility for noble-gas radio-isotope measurements:
This facility is designed to provide researchers with the ability to accurately date water and ice cores using the natural radio-isotopes in the sample. Radiocarbon dating has been a revolutionary tool in providing answers to a range of questions in anthropology, archaeology and the earth sciences. However, radiocarbon dating has a strong limitation in that it can only date periods from 1000–50 000 years: the use of radioactive noble-gas isotopes can extend this range out to 1 year to 1 million years. This capability in the new facility is expected to support new understanding of processes in artesian reservoirs, ocean currents and geology that may affect questions of water availability, climate and environmental change.Read moreRead less

This project aims to design distillation and absorption columns, perhaps the most important unit operations in a liquefied natural gas (LNG) plant, and whose optimization is integral to overall performance of any LNG plant. This project will use 3D printers to rapidly prototype concepts of columns and their internals, and test them using flow characterization tools and numerical models. The final outcome of the project will be a set of designs of the columns, which should be more efficient, safer and cheaper to operate, and have smaller physical and environmental footprints, thus helping the Australian LNG industry to stay globally competitive.Read moreRead less
