Protein-protein interactions mediate all fundamental cellular processes, yet the structural complexity of protein assemblies mean they are often difficult to characterise using traditional analytical methods. This project will develop and demonstrate novel mass spectrometric approaches towards a molecular level description of the structure and interactions of biological protein complexes, which in turn may underpin the rational design of drugs for the treatment of a range of human health conditions. This project will also provide training of young researchers to the highest international standards in mass spectrometry and protein science, for benefit to Australian industry and research.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.

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 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.

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
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.

Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information ....Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information on the nature of the reactive intermediates themselves, the nature of the products formed, and the reaction dynamics, and they are of fundamental importance for an understanding of chemical reactivity generally. The methodology developed will be applicable to the investigation of a wide range of processes.Read moreRead less
New mechanisms and methods in carbene and nitrene chemistry. Carbenes and nitrenes are highly reactive intermediates of theoretical and mechanistic significance and synthetic versatility in organic chemistry. In spite of high reactivity, selective and high-yielding reactions can be performed, leading to products that may be difficult or impossible to synthesise by other methods. They have practical applications in photo-affinity labelling of biomolecules, and photolithography. This project will ....New mechanisms and methods in carbene and nitrene chemistry. Carbenes and nitrenes are highly reactive intermediates of theoretical and mechanistic significance and synthetic versatility in organic chemistry. In spite of high reactivity, selective and high-yielding reactions can be performed, leading to products that may be difficult or impossible to synthesise by other methods. They have practical applications in photo-affinity labelling of biomolecules, and photolithography. This project will contribute fundamental knowledge of the nature and reactions of these species by using direct spectroscopic observation. We are proposing the occurrence of novel types of reactions and the formation of several new reactive intermediates as well as a technique for the stabilization of reactive intermediates by incorporation into macrocyclic frameworks.Read moreRead less

The Evolution of Dwarf Elliptical Galaxies: Nature or Nurture? From observations obtained at world-class facilities such as Gemini, this international team of experts will determine whether it is the intrinsic properties of dwarf Ellipticals (nature), or the influence of a neighbouring large galaxy (nurture), that determines the history of star formation in these small galaxies. Studies of local examples of this galaxy type, which may be the first objects formed in the Universe, have shown an u ....The Evolution of Dwarf Elliptical Galaxies: Nature or Nurture? From observations obtained at world-class facilities such as Gemini, this international team of experts will determine whether it is the intrinsic properties of dwarf Ellipticals (nature), or the influence of a neighbouring large galaxy (nurture), that determines the history of star formation in these small galaxies. Studies of local examples of this galaxy type, which may be the first objects formed in the Universe, have shown an unexpected and unexplained diversity of star formation histories. The outcomes of this research are relevant to the evolution of stars, the evolution of the chemical elements, and to the formation of larger galaxies.Read moreRead less
