Enhancing our understanding of metallochemistry in neurobiology with modern electron paramagnetic resonance (EPR) spectroscopy. Many neurological diseases involve protein accumulation that appears causally linked to abnormal levels of metal ions in the brain. This project will use a special technique called electron paramagnetic resonance to uncover how these metals interact with specific proteins at the molecular level and how drug treatments can modify these interactions.
The role of structure in the formation and properties of glasses. This project aims to investigate the role of local atomic structure in the formation and mechanical properties of glasses by applying newly developed structure-determination methods. This project expects to establish why glasses form and how their structure gives rise to their undesirable, and limiting, brittle mechanical failure. The anticipated outcomes of this project are better ways to measure the atomic structure of disorder ....The role of structure in the formation and properties of glasses. This project aims to investigate the role of local atomic structure in the formation and mechanical properties of glasses by applying newly developed structure-determination methods. This project expects to establish why glasses form and how their structure gives rise to their undesirable, and limiting, brittle mechanical failure. The anticipated outcomes of this project are better ways to measure the atomic structure of disordered materials and the generation of more clear-cut structure-property relationships for glasses. This will provide significant benefit to Australian industries by enabling the design of better glass-forming systems and stronger, tougher glasses.Read moreRead less
Electronic-vibrational spectroscopy: A new probe for structure and function. This project aims to solve a major challenge in ultrafast spectroscopy: to identify and quantify competing reaction pathways in complex photochemical systems. Ultrafast Spectroscopy provides information on excited-state processes of photochemical reactions, however, unravelling heterogeneous systems with competing parallel processes remains difficult. Multidimensional electronic-vibrational spectroscopy, sensitive to el ....Electronic-vibrational spectroscopy: A new probe for structure and function. This project aims to solve a major challenge in ultrafast spectroscopy: to identify and quantify competing reaction pathways in complex photochemical systems. Ultrafast Spectroscopy provides information on excited-state processes of photochemical reactions, however, unravelling heterogeneous systems with competing parallel processes remains difficult. Multidimensional electronic-vibrational spectroscopy, sensitive to electronic dynamics and molecular structure, is expected to overcome this barrier. This new level of detail will profoundly enhance our understanding of energy and chemical conversion in complex systems and will reveal design targets for optimising next-generation light-energy harvesting, conducting, and emitting materials.Read moreRead less
Expanding the molecular tool set for structural studies of proteins and their complexes. Many applications in medical science and drug development depend on our ability to determine the 3D structures of proteins, protein assemblies and protein-ligand complexes. This project will develop novel lanthanide-binding tags and crosslinking agents that can be coupled to unnatural amino acids introduced into proteins with advanced protein chemistry techniques. These new tools will facilitate the collecti ....Expanding the molecular tool set for structural studies of proteins and their complexes. Many applications in medical science and drug development depend on our ability to determine the 3D structures of proteins, protein assemblies and protein-ligand complexes. This project will develop novel lanthanide-binding tags and crosslinking agents that can be coupled to unnatural amino acids introduced into proteins with advanced protein chemistry techniques. These new tools will facilitate the collection of structure restraints by nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) and mass spectrometry, which are needed to generate accurate models of proteins and their complexes with other molecules. Major beneficial outcome will include an increase in the number of protein targets amenable to rational drug design and improved methods for generating new drug leads.Read moreRead less
Photonic circuitry from the noble metals: nanocrystal coupling. Linear arrays of crystalline nanoparticles are able to act in a manner analogous to an optical fibre, but with much smaller dimensions. This project will investigate the underlying principles of waveguiding within the arrays and aims to build and test sections of such optical fibres, thereby assessing their use in optical circuits.
Structural studies of host-pathogen interactions. The host-pathogen interface represents a major frontier for biomedical and biotechnological applications. This project aims to understand at the atomic level two such interfaces. In the first instance, the project will elucidate the molecular basis for inhibition of premature host cell death by poxviruses, in particular vaccinia and variola virus, the causative agent of smallpox. In the second instance, the aim is to understand how defensins, a ....Structural studies of host-pathogen interactions. The host-pathogen interface represents a major frontier for biomedical and biotechnological applications. This project aims to understand at the atomic level two such interfaces. In the first instance, the project will elucidate the molecular basis for inhibition of premature host cell death by poxviruses, in particular vaccinia and variola virus, the causative agent of smallpox. In the second instance, the aim is to understand how defensins, a major class of host defence molecules, recognise microbial targets such as fungi, and exert a potent antimicrobial effect. Understanding the precise molecular mechanisms operating at both these host-pathogen interfaces this will provide novel avenues for the design of antiviral and antimicrobial agents.Read moreRead less
The ins and outs of HIV biology. This project aims to delineate the fundamental mechanisms that regulate the production of HIV and the ability of HIV to cause AIDS in infected patients. It will utilise state-of-the-art technologies to unearth new clues that govern the biology of HIV, with the ultimate goal to develop novel vaccine and treatment strategies against HIV.
Novel cement-graphene oxide composite: understanding its composite structure via nano-mechanics based modelling and experimental tests. A high performance cement composite will be developed to reduce the usage of cement, and steel reinforcement, thus decrease carbon dioxide emissions, reduce labour costs, and promote sustainability. Modern modelling techniques will advance the knowledge in cement and concrete field and maintain the leading position of Australia.
Surface modification of semiconducting organic charge transfer complexes with metal nanoparticles to create a new class of multifunctional materials. This project aims to deliver a facile and cheap method to produce a class of nanostructured composite materials to be used in applications which will have environmental and social benefits such as photocatalyst development for water purification, biosensing and the creation of antibacterial fabrics to prevent the spread of infection.
Structural analysis of poxviruses: advancing our understanding of complex DNA viruses and their in vivo crystals. This project will use innovative structural biology approaches to investigate two key particles of poxviruses, the largest viruses infecting humans. Advance in understanding of immature particles and natural crystals of poxviruses will provide the basis for the development of broad-spectrum antivirals and novel microparticles for vaccine-delivery.
