The formation of negative ions and neutrals in the gas phase. Structure, reactivity and mechanism. Mass spectrometry is an analytical technique used to provide information concerning the structure of a chemical compound: it is particularly useful when dealing with small amounts of biologically important molecules. It is also a facility in which charged species can be converted into transient neutrals. This project will (i) produce information about negative ion fragmentations in order to extend ....The formation of negative ions and neutrals in the gas phase. Structure, reactivity and mechanism. Mass spectrometry is an analytical technique used to provide information concerning the structure of a chemical compound: it is particularly useful when dealing with small amounts of biologically important molecules. It is also a facility in which charged species can be converted into transient neutrals. This project will (i) produce information about negative ion fragmentations in order to extend the applicability of analytical negative-ion mass spectrometry, (ii) form neutral molecules and related species which are found in stellar dust clouds and investigate their chemistry, and (iii) train graduates in ion chemistry to the highest international standards.Read moreRead less
The recovery of Cu from chalcopyrite-pyrite containing concentrates, ores and tailings. Chalcopyrite, a major source of Cu, is often associated in ores with the valueless mineral pyrite. The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;
- leaching of Cu from ores and tailing in a heap leach ....The recovery of Cu from chalcopyrite-pyrite containing concentrates, ores and tailings. Chalcopyrite, a major source of Cu, is often associated in ores with the valueless mineral pyrite. The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;
- leaching of Cu from ores and tailing in a heap leach environment and
- leaching of Cu in a concentrated chalcopyrite-pyrite reactor environment.
These aims will be achieved via an integrated surface-solution speciation approach allowing the manipulation of surface properties.

Cumulenes and Heterocumulenes - Stellar Molecules and New Materials. This project involves the formation and characterisation of transient neutrals (formed in the mass spectrometer by neutralisation of charged precursor ions) which are either found in stellar dust clouds, or related molecules which may be either potential stellar molecules or have importance in the development of new materials. This work may lead to a better understanding of how biomolecules are formed in interstellar environs. ....Cumulenes and Heterocumulenes - Stellar Molecules and New Materials.

This work may lead to a better understanding of how biomolecules are formed in interstellar environs. The Adelaide and Berlin groups are internationally known, already with ongoing collaboration. This application seeks to extend the scope of this world-class research, and to train the premier graduate students in astrochemistry.Read moreRead less
New Methodology for the Stereoselective Construction of Oxygen Heterocycles and Rare Sugar Analogues. The overall goal of this research is to develop new synthetic methods, particularly ones that exhibit high levels of stereocontrol. Current research efforts are directed towards the stereoselective construction of oxygen heterocycles and rare sugar analogues both in their racemic and chiral forms utilising 1,2-dioxines containing tethered hydroxyl moieties as the key chemical precursors. It is e ....New Methodology for the Stereoselective Construction of Oxygen Heterocycles and Rare Sugar Analogues. The overall goal of this research is to develop new synthetic methods, particularly ones that exhibit high levels of stereocontrol. Current research efforts are directed towards the stereoselective construction of oxygen heterocycles and rare sugar analogues both in their racemic and chiral forms utilising 1,2-dioxines containing tethered hydroxyl moieties as the key chemical precursors. It is envisaged that these investigations will lead to the development of simple experimental protocols for the synthesis of new bioactive organics.Read moreRead less
Laser Diagnostics of Soot Formation in Precessing Jet Flames. In many practical combustion systems (e.g., boiler furnaces and rotary kilns), flame radiation is the major contributor to the required heat transfer. Soot formation is a means of enhancing flame radiation provided the soot is completely oxidised within the flame so that there are no soot emissions. The enhanced flame radiation can have a significant economic and environmental impact on plant operation (changes to the parameters tha ....Laser Diagnostics of Soot Formation in Precessing Jet Flames. In many practical combustion systems (e.g., boiler furnaces and rotary kilns), flame radiation is the major contributor to the required heat transfer. Soot formation is a means of enhancing flame radiation provided the soot is completely oxidised within the flame so that there are no soot emissions. The enhanced flame radiation can have a significant economic and environmental impact on plant operation (changes to the parameters that influence soot formation can also influence NOx and greenhouse gas emissions). The objectives of this project are to identify and quantify the operating parameters that influence soot formation and destruction in such flames.Read moreRead less
