Summary
Xe-plasma dual beam for advanced future materials. This project aims to establish a state of the art Xe-Plasma dual-beam facility providing characterisation and fabrication capabilities to Australia’s research community. The project will use two beams - one Xe, the other electrons - to mill the surface of bulk materials which are subsequently analysed by electron or ion beam techniques to determine atomic-scale microstructure(s) and compositions.

This project aims to establish a state of the art Xe-Plasma dual-beam facility providing characterisation and fabrication capabilities to Australia’s research community. The project will use two beams - one Xe, the other electrons - to mill the surface of bulk materials which are subsequently analysed by electron or ion beam techniques to determine atomic-scale microstructure(s) and compositions. Anticipated outcomes are advanced materials engineering and new knowledge about ancient and future materials. This is expected to provide significant advances across a variety of fields including material science, engineering and geology and enhance trans-disciplinary collaborations.Read moreRead less

Summary
An analytical transmission electron microscope for the investigation of functional materials, earth processes and novel condensed matter. Sustainablity depends on the delivery of clean energy, pristine water and air, and the manufacture of consumer products with small environmental footprints. Modelling long-term impacts requires an understanding of the hydro-geological cycles. The technologies are well known—efficient electronics, fuel cells, lightweight composites, and so on—but delivery is ....An analytical transmission electron microscope for the investigation of functional materials, earth processes and novel condensed matter. Sustainablity depends on the delivery of clean energy, pristine water and air, and the manufacture of consumer products with small environmental footprints. Modelling long-term impacts requires an understanding of the hydro-geological cycles. The technologies are well known—efficient electronics, fuel cells, lightweight composites, and so on—but delivery is not straightforward. It is clear, however, that novel materials manipulated at fine scales will be key. Transmission electron microscopy (TEM) guides the development of sustainable technologies. The new TEM facility at ANU will accelerate current studies, by enhancing the materials research portfolio, and extending national and international collaborations in materials, geological and earth sciences.Read moreRead less

Summary
Quantitatively probing the nanoscale plasticity of a single grain boundary. This project aims to study grain boundaries, which are important in the mechanical behaviour of nanomaterials. However, the exact contribution of individual grain boundaries to mechanical properties is not well understood, affecting advanced materials design.

This project aims to study grain boundaries, which are important in the mechanical behaviour of nanomaterials. However, the exact contribution of individual grain boundaries to mechanical properties is not well understood, affecting advanced materials design. This project will use in-situ deformation transmission electron microscopy techniques to reveal how individual grain boundaries deform and interact with dislocations, and to link directly the structures and orientation of individual grain boundaries with mechanical behaviours. Expected results are better structural design of advanced metallic nanomaterials with superior mechanical performance.Read moreRead less
Dislocation motion and anelastic recovery in layered ceramic titanate. This project aims to research deformation and facture in brittle ceramic nanowire materials and anelastic behaviour in tensile deformation. Layered sodium titanate is used in energy storage and water treatment, but in-situ tensile tests have observed unconventional deformation behaviour, with significant dislocation motion and anelastic recovery. This project will study the deformation mechanism in layered sodium titanate nan ....Dislocation motion and anelastic recovery in layered ceramic titanate. This project aims to research deformation and facture in brittle ceramic nanowire materials and anelastic behaviour in tensile deformation. Layered sodium titanate is used in energy storage and water treatment, but in-situ tensile tests have observed unconventional deformation behaviour, with significant dislocation motion and anelastic recovery. This project will study the deformation mechanism in layered sodium titanate nanowires through molecular dynamics simulations, empirical interatomic potential, and in situ TEM experiments. Expected outcomes include knowledge of the deformation mechanism of this layered titanate which can be broadened to technologically important layered ceramic materials.Read moreRead less

Summary
Parkinson’s disease is a degenerative disorder of the central nervous system in which the underlying cause is mostly unknown. To pave the way to a better understanding of what goes wrong, this study will investigate the function of PINK1 and Parkin, two proteins that are mutated in inherited forms of the disease that play important roles in maintaining cellular health. The results of this study will be used in exploring new therapeutic targets for the treatment of Parkinson’s disease symptoms.
Investigating The Substrate Specificity Of The Master Kinase LKB1 And The Pharmacological Targeting Of Its Substrate NUAK2 To Treat Cancers

Summary
Kinases are key regulators of cell signaling and emerging drug targets. LKB1 kinase specifically activates a set of substrates to modulate cellular processes, and its substrate NUAK2 is a novel target for cancer. I will elucidate the structural basis of how LKB1 recognizes its substrates and develop inhibitors targeting LKB1-NUAK2 interaction for cancer treatment. My project will provide key insights into kinase-dependent signaling and establish a new framework for therapeutics development.

Summary
Sphingosine kinase is a protein that when dysregulated is involved in cancer development and progression. We have recently made a substantial breakthrough in this area by identifing a naturally occuring variant of sphingosine kinase that is constantly activated and has an enhanced ability to induce cancer. In this study we will examine and target this form of sphingosine kinase as a potential therapeutic intervention in cancer.
The Impact Of The Changes In Levels Of Adhesion Molecules NCAM2 And DsCAM On Synapse Formation And Function: Implications For Down Syndrome

Funding Amount

Summary
Down syndrome (DS) results from triplication of chromosome 21 and leads to mental retardation, molecular mechanisms of which are not understood. We found that two proteins, NCAM2 and DSCAM, encoded at chromosome 21 are highly expressed in synapses. Synapses are specialized contacts between neurons which allow neurons to process information in the brain. In this project we will test a hypothesis that changes in NCAM2 and DSCAM expression result in synapse abnormalities observed in DS.
