New Enantiomeric Separation Technologies for Natural Product, Pharmaceuticals and Environmental Pollutant Characterisation. Enantiomeric characterisation allows evaluation of drug purity for potentially harmful constituents, consumer protection against adulteration of essential oils and natural materials, and study of chemical interactions in biochemical/environmental systems. Chromatograph technologies (GC, HPLC and CE)for enantioseparation are available, however limitations prevent multicompon ....New Enantiomeric Separation Technologies for Natural Product, Pharmaceuticals and Environmental Pollutant Characterisation. Enantiomeric characterisation allows evaluation of drug purity for potentially harmful constituents, consumer protection against adulteration of essential oils and natural materials, and study of chemical interactions in biochemical/environmental systems. Chromatograph technologies (GC, HPLC and CE)for enantioseparation are available, however limitations prevent multicomponent characterisation of complete sample mixtures. Critical choices involve: choosing a chiral selector that interacts differentially upon all enantiomers; incorporation of selector into high-efficiency chromatographic systems; application to all target compounds in the sample. We will synthesise novel chiral selectors, incorporate these into new separation columns, apply ultra-high resolution 2-dimensional GCxGC to broad-spectrum chiral analysis of volatile chemical samples.Read moreRead less
Immobilised Lipid Chromatography for Membrane Protein Isolation and Analysis. Current techniques for membrane protein are inadequate for the emerging proteomic challenge, in which approximately 40% of proteins are predicted to be membrane associated. The aim of this proposal is to develop a new approach to purify membrane proteins using our recently-developed immobilised membrane chromatography materials. The present proposal will provide a new high-resolution separation technique that allows is ....Immobilised Lipid Chromatography for Membrane Protein Isolation and Analysis. Current techniques for membrane protein are inadequate for the emerging proteomic challenge, in which approximately 40% of proteins are predicted to be membrane associated. The aim of this proposal is to develop a new approach to purify membrane proteins using our recently-developed immobilised membrane chromatography materials. The present proposal will provide a new high-resolution separation technique that allows isolation and on-line mass analysis of complex mixtures of membrane proteins for subsequent proteomic analysis, high-throughput screening or structural studies and could form the basis for further development of new commercial tools for membrane protein analysis.Read moreRead less

Purchase of a multi-purpose Schottky field emission gun scanning electron microscope. Scanning electron microscopy is a basic analytical tool for imaging surfaces of natural and synthetic materials and identification of nanometre-scale features and their compositions. At the University of Tasmania, it supports four of our six designated priority research themes: Antarctic and Marine Studies, Environment, Frontier Technologies, and Sustainable Primary Production.

Scanning electron microscopy is a basic analytical tool for imaging surfaces of natural and synthetic materials and identification of nanometre-scale features and their compositions. At the University of Tasmania, it supports four of our six designated priority research themes: Antarctic and Marine Studies, Environment, Frontier Technologies, and Sustainable Primary Production. Our research depending on this technique includes many fundamental and applied topics from a wide range of disciplines, such as developing portable detection devices for explosives, finding more efficient and sustainable ways to explore for ore, investigating the effects of climate change on marine ecosystems and improving salinity and drought tolerance of crops.Read moreRead less
The Synthesis and Analysis of Certain Explosives and Illicit Drugs for Improved Forensic Detection. There is an increasing demand within law enforcement agencies, worldwide, for selective and sensitive methods for the determination of illicit substances. Over the last decade Deakin University chemists have played a major role in establishing the utility of chemiluminescent reactions for the determination of a variety of pharmaceutical opiates in process streams. This project seeks to build upon ....The Synthesis and Analysis of Certain Explosives and Illicit Drugs for Improved Forensic Detection. There is an increasing demand within law enforcement agencies, worldwide, for selective and sensitive methods for the determination of illicit substances. Over the last decade Deakin University chemists have played a major role in establishing the utility of chemiluminescent reactions for the determination of a variety of pharmaceutical opiates in process streams. This project seeks to build upon these successes, in order to develop innovative analytical strategies for forensic detection of certain illicit drugs and explosives. The results of this research have the potential to revolutionise key aspects of forensic analysis.Read moreRead less

Analytical and Preparative Enantioselective Chromatography. Enantiomers are forms of the same molecule that are non-superimposable mirror images of one another, like a left hand and a right hand. Because they are so similar they are very difficult to separate. However, they have very different biological properties, such as when used as drugs. One enantiomer may be beneficial while the other has no effect or sometimes is even toxic. Therefore it is important to be able to tell how much of ea ....Analytical and Preparative Enantioselective Chromatography. Enantiomers are forms of the same molecule that are non-superimposable mirror images of one another, like a left hand and a right hand. Because they are so similar they are very difficult to separate. However, they have very different biological properties, such as when used as drugs. One enantiomer may be beneficial while the other has no effect or sometimes is even toxic. Therefore it is important to be able to tell how much of each enantiomer is present in a sample and to be able to separate them. This facility will allow us to do both of these things.Read moreRead less
Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact ....Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact process. Since the leaching is typically applied to ores rich in copper, resins for the recovery of copper will also be designed. Laboratory proving trials will be conducted and successful candidates will be considered for future commercialisation of a Resin-in-Pulp leaching and recovery process.Read moreRead less
Selective Detection and Removal of Contaminants That Have an Adverse Impact on Australian Raw Sugar Quality. Sugar is Australia's 2nd largest agricultural crop with 80-85% exported earning $2 billion in export revenue. Whilst Australia is arguably the most reliable supplier of premium raw sugar the implementation of improved processing technologies by rivals has (and without appropriate research strategies will continue to) eroded some of the long-held Australian advantages.

Sugar is Australia's 2nd largest agricultural crop with 80-85% exported earning $2 billion in export revenue. Whilst Australia is arguably the most reliable supplier of premium raw sugar the implementation of improved processing technologies by rivals has (and without appropriate research strategies will continue to) eroded some of the long-held Australian advantages.
Our innovative approaches will improve raw sugar quality, measurement methods, and allow new product development (value adding), enabling Australia to maintain its? world leading position. Importantly, our technologies enable improvements of specific quality issues (and potentially as yet unidentified issues), further differentiating the Australian product in the international marketplace.
