Biomolecular chemical survival strategies of terrestrial extremophiles and the spectroscopic search for life on Mars. This project is aimed to place Australian research at the forefront of developments in the search for extraterrestrial life, the evolution of life on earth, and the design of new probes for the identification of microorganisms.

This project is aimed to place Australian research at the forefront of developments in the search for extraterrestrial life, the evolution of life on earth, and the design of new probes for the identification of microorganisms. The research will link key centres in Australia and the UK with international space agencies (NASA and the European Space Agency) in the search for cutting edge techniques to be used in the search for extraterrestrial life forms and their links to paleo and extremophile life forms on Earth.

The expected benefits that will arise will include: green chemical processes with improved environmental and economic impacts; improved treatments and diagnoses of diseases; understanding of fundamental geological processes; identification of the earliest forms; studies of archaeological artefacts; evolution of life on Earth; the design of improved dental materials. Ultimately, this research will include economic and social benefits in; industrial processes; the mining industry; medicine; and dentistry. An understanding of the origin and early evolution of life on Earth also has many social implications.Read moreRead less
Water storage in the earth's mantle - understanding the process of OH incorporation in olivine. The amount of water in the Earth's mantle is thought to be sufficient to replace the surface oceans more than ten times. Whether this water exists in a fluid, melt, or mineral is important for understanding a range of mantle properties. The entire upper mantle water budget may be accommodated at defect sites in the mineral olivine. However, defects found in natural olivine do not correspond to thos ....Water storage in the earth's mantle - understanding the process of OH incorporation in olivine. The amount of water in the Earth's mantle is thought to be sufficient to replace the surface oceans more than ten times. Whether this water exists in a fluid, melt, or mineral is important for understanding a range of mantle properties. The entire upper mantle water budget may be accommodated at defect sites in the mineral olivine. However, defects found in natural olivine do not correspond to those produced
experimentally. Therefore, previous conclusions on water storage in the mantle are questionable. To address this problem the mechanism of water incorporation in olivine will be investigated using experimental petrology and spectroscopy.Read moreRead less
Negative ion mass spectrometry: fundamentals and applied applications. 1. We seek to establish negative ion mass spectrometry as a major technological tool for the sequencing of peptides and proteins. In this context, we will investigate the structures and modes of action of peptide complexes which may be of importance for the treatment and control of heart disease and stroke.
2. Negative ions of known structure will be converted (in the mass spectrometer) into transient (and reactive) molecule ....Negative ion mass spectrometry: fundamentals and applied applications. 1.

In this context, we will investigate the structures and modes of action of peptide complexes which may be of importance for the treatment and control of heart disease and stroke.
2. Negative ions of known structure will be converted (in the mass spectrometer) into transient (and reactive) molecules which are present in interstellar ice and dust clouds. The structures and chemistry of such molecules are of importance in understanding the origins of life on this planet.Read moreRead less
The geochemistry of trace elements with variable oxidation states. The understanding of many earth processes is based upon an interpretation of differences in the relative abundance and/or distribution of elements which occur in more than one oxidation state. However, the redox states that control the geochemical behaviour of an element in a melt are not necessarily retained on cooling. This work aims to determine the oxidation states of geologically important elements, in situ under magmatic ....The geochemistry of trace elements with variable oxidation states. The understanding of many earth processes is based upon an interpretation of differences in the relative abundance and/or distribution of elements which occur in more than one oxidation state. However, the redox states that control the geochemical behaviour of an element in a melt are not necessarily retained on cooling. This work aims to determine the oxidation states of geologically important elements, in situ under magmatic conditions, using XANES spectroscopy. The results will allow geological signatures to be correctly interpreted and allow models for topics ranging from ancient mantle temperatures to rates of melt migration to be better constrained.Read moreRead less
