This project aims to investigate radical new approaches to reduce chemical and energy requirements for transformation of indigenous natural graphite to a high-value material graphene. The graphite which will be used is the by-product of the Uley mines of South Australia. Graphene is an atomically thin arrangement of carbon atoms with combinations of remarkable chemical inertness, strength, and massive surface area. Utilising fluid phase dispersed graphene, this project aims to develop scalable and industrially-adaptable methods to manufacture thin yet mechanically robust, inert, fouling-resistant, highly-permeable graphene-based asymmetric membranes. These advanced membranes are expected to find wide application in reducing discharge of mining effluents and recovery of precious metals.Read moreRead less

This project aims to evaluate and validate broad capabilities of advanced chemical profiling using benchtop and portable gas chromatography–mass spectrometry for forensic applications. Establishing guidelines for sampling various matrices, key performance measures, and improving chemical and residue identification for drug profiling in clandestine laboratories and public venues, chemical warfare agents, and chemical toxins is expected. Anticipated outcomes for project partners in defence and policing include detailed knowledge of sample and residue composition and on-site assessment of chemical risks with immediate feedback. Benefits should include improved community and security services safety by enhanced detection of harmful substances.Read moreRead less
Pre-blast screening of improvised explosive devices - a National counter-terrorism initiative. The proposed research is focused on the specific needs of Australian counter-terrorism interests, including those of border protection, the customs service, transport authorities, forensic laboratories, etc. The support of this proposal will ensure that Australia, and its States and Territories are protected against terrorist threats.

The proposed research is focused on the specific needs of Australian counter-terrorism interests, including those of border protection, the customs service, transport authorities, forensic laboratories, etc. The support of this proposal will ensure that Australia, and its States and Territories are protected against terrorist threats. The support provided by the collaborating organisations from the various Federal and State police and forensic agencies, and the customs service, etc, highlights the importance of this project to the nation. Finally, a PhD student and a research assistant will be involved with the project and will gain specialised skills positioning them to make strong contributions to Australia's counter-terrorism measures.Read moreRead less
Reconciliation strategies for continuous variable quantum key distribution. This project aims to advance a novel key distribution method, called quantum key distribution, which distributes secure keys using the quantum state of optical channels. Key distribution is a foundational part of data security, allowing digital keys to be securely exchanged between two or more parties, before they are used to protect and share information. The expected outcome is new rateless error correction codes desi ....Reconciliation strategies for continuous variable quantum key distribution. This project aims to advance a novel key distribution method, called quantum key distribution, which distributes secure keys using the quantum state of optical channels. Key distribution is a foundational part of data security, allowing digital keys to be securely exchanged between two or more parties, before they are used to protect and share information. The expected outcome is new rateless error correction codes designed specifically to implement quantum key distribution over long distances. Quantum key distribution is beneficial for ultra-secure communications as it avoids the vulnerability to weak random numbers and quantum-computing brute force attacks that currently threated the security of data protected by existing methods.

Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity a ....Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity around the Bay. While dredging and on-land treatment of sediments is being adopted at the most severely contaminated sites, the cost of this approach is exorbitant. For sites where removal of contaminated sediments cannot be justified, the approach proposed in this study of a technology that entraps contaminants and enhances their in situ biodegradation is potentially a way forward.Read moreRead less
A Laser Guide Star using a High Power, Synchronously Pumped Optical Parametric Oscillators. We will develop a novel high power source of 589nm coherent (laser) light to be used to create a laser guide star by exciting sodium atoms in the earth's upper atmosphere (the mesosphere). This is needed to determine the distortion caused by the atmosphere on an optical beam propagating through it and generate the information needed to correct those distortions using an adaptive optics telescope.

The aim of this project is to develop a microconcentrator for deployment on house roofs that will produce both solar hot water and solar electricity with a combined efficiency above 60%. The system will have a low profile and will be nearly invisible from the street. The system will track the sun. Concentration will be accomplished by a mixture of refraction and reflection.

The aim of this project is to develop a microconcentrator for deployment on house roofs that will produce both solar hot water and solar electricity with a combined efficiency above 60%. The system will have a low profile and will be nearly invisible from the street. The system will track the sun. Concentration will be accomplished by a mixture of refraction and reflection. About 20% of the sunlight will be converted to electricity using lines of tiny solar cells, with the balance being converted to heat which is removed by cooling fluid and stored in hot water tanks.Read moreRead less
Oxidation product generation during heating and storage of bio-fuels and alternative fuels assessed by multidimensional gas chromatography. Renewable bio-fuels offer much promise as a replacement for fossil fuels. However, they have a tendency to oxidise when prepared and used, potentially forming gums and solid deposits in engines. The objective of this project is the identification of these deposits and subsequent prevention during engine operation.
