The influenza virus continues to pose a serious health risk to Australians and remains a leading cause of death. The molecular characterisation of emerging strains of the virus lies at the heart of current surveillance procedures vital to vaccine preparation and the development of new anti-viral drugs. This research will advance a world-first proteomics surveillance of the virus developed in this laboratory that will enable it to be characterised in-field at the site(s) of infection outbreaks. This rapid response is vital, particularly in the event of a pandemic or a deliberate release of the virus in a bioterrorist attack.Read moreRead less

In particular an exciting new class of methods whose computational cost scales linearly with system size. Our goal is to develop scalable parallel implementations of these methods. If realized this will revolutionize computation, enabling first principles calculations on truly nanoscale systems, such as enzymes and molecular electronic devices.Read moreRead less
Towards a high density silicon phase change memory device. This project builds upon our exciting recent findings that amorphous silicon can be transformed to a conducting crystalline phase following small-scale indentation. Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develo ....Towards a high density silicon phase change memory device. This project builds upon our exciting recent findings that amorphous silicon can be transformed to a conducting crystalline phase following small-scale indentation. Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develop an entirely new information storage system: a high-density silicon phase change memory. This project aims to study small-scale transformation behaviour in silicon and to design demonstrator memory devices based on both micro-electromechanical systems and solid state technologies.Read moreRead less

New Polymers for Cellulose-based Bioplastics. We will design new cellulose derivatives by combining carefully engineered synthetic polymers to cellulose. We will explore the fundamental science underpinning the manufacture of these bioplastics, and apply the concept to the design of two new materials, with (super)hydrophobic and antibacterial properties. These materials have the potential to replace synthetic plastics, which comprise one of the major outputs of the chemical industry worldwide. P ....New Polymers for Cellulose-based Bioplastics.

These materials have the potential to replace synthetic plastics, which comprise one of the major outputs of the chemical industry worldwide. Plastic is present everywhere in human life, but its manufacture and disposal have a strong negative impact on the environment; the new materials manufactured in this project are viable alternatives to plastics, and are sustainable from a production and disposal point of view.Read moreRead less

Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, whic ....Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, which appears thus to be an inherent property of the polymer, the project aims at formulating new hypotheses to explain this phenomenon, and to confirm them experimentally. The "chelation" hypothesis will be validated by modifying the structure of polymers, and the "spontaneous precipitation" hypothesis by assessing the effect of solutes on the equilibrium water content of polymers. NMR and FTIR spectrometric techniques will be used to gain further insight into the mechanism of calcification. Methods to prevent the calcification will potentially result from these experiments, however, anticalcification agents will also be incorporated into hydrogels and their effect evaluated in calcification assays.Read moreRead less
