New Strategies for Modelling Polyoxometalates. Polyoxometalates are a versatile class of genuine nanomaterials with remarkable chemical and physical properties and dimensions ranging from tens to tens of thousands of atoms. Designing functional materials which exploit their enormous potential is limited by practical difficulties in their structural characterization and restrictions on our ability to model their behaviour. In this project, we will develop a new strategy for computer modelling of ....New Strategies for Modelling Polyoxometalates. Polyoxometalates are a versatile class of genuine nanomaterials with remarkable chemical and physical properties and dimensions ranging from tens to tens of thousands of atoms. Designing functional materials which exploit their enormous potential is limited by practical difficulties in their structural characterization and restrictions on our ability to model their behaviour. In this project, we will develop a new strategy for computer modelling of polyoxometalates based on the classical molecular mechanics approach and high-level techniques. This novel line of attack will be exploited in the characterization of large and highly substituted derivatives which are key to developing functional materials.Read moreRead less

Patterned assemblies of molecules on surfaces. Because of their redox and photophysical properties, artificial porphyrin systems have been designed for applications such as light-harvesting antennae, catalysts and sensors. Control of molecular orientation is required in order to construct practical devices, and in this project methods of assembling porphyrins on surfaces in well-defined patterns will be developed.

Because of their redox and photophysical properties, artificial porphyrin systems have been designed for applications such as light-harvesting antennae, catalysts and sensors. Control of molecular orientation is required in order to construct practical devices, and in this project methods of assembling porphyrins on surfaces in well-defined patterns will be developed. Sophisticated methods will be used to characterise the films produced in these ways, in order to provide the information necessary to refine procedures and design new molecules suitable for advanced applications. Expected outcomes are new methods and architectures that can ultimately yield devices that act at the molecular level.Read moreRead less

The primary outcome will be a fundamental new knowledge on cyclotide structures and a new protein engineering method to design stabilised proteins. Because cyclotides have significantly higher stabilities than conventional proteins, they have a range of pharmaceutical and agricultural applications. Both fields of use have the potential for very great economic and social benefits for Australia. From a pharmaceutical perspective our computing development will greatly facilitate the design of stabilised peptide-based drugs using the cyclotide framework. Such drugs have potential sales of several billion dollars per annum and the royalty returns from successful commercialisation of IP can be substantial.Read moreRead less

This project aims to determine the molecular structure of the interface between novel peptide self-assemblies and cell membranes through x-ray diffraction and molecular simulation. The project will generate knowledge to enable atomic scale engineering of peptide nanomaterials, and exploitation of these materials to modulate cell responses. Expected outcomes include designed peptide nanostructures with specific chemical and physical cues to promote sustainable growth of desired cells, whilst inhibiting undesirable responses. These outcomes should provide benefits in terms of a practical toolkit for tailoring structure and function of peptide nanostructures and open up a new era in molecular design of smart biomaterials. This easily scalable, new materials platform will contribute to emerging high-value manufacturing industries in Australia.Read moreRead less

Scaling the particles' synthesis, including using Australian sunlight, will enable multi-gram production allowing real-world applications.Read moreRead less
Surfacing urban wetlands in two urban renewal sites in Sydney. Urban wetlands in Australia provide benefits for climate change mitigation, pollution reduction, habitat provision and socioecological connection. However, in large cities like Sydney, urban wetlands are unseen because undergrounded, and, therefore not adequately understood. This illegibility, and loss of understanding by residents, planners and policy makers impedes wetlands' good management. This project surfaces wetlands through v ....Surfacing urban wetlands in two urban renewal sites in Sydney. Urban wetlands in Australia provide benefits for climate change mitigation, pollution reduction, habitat provision and socioecological connection. However, in large cities like Sydney, urban wetlands are unseen because undergrounded, and, therefore not adequately understood. This illegibility, and loss of understanding by residents, planners and policy makers impedes wetlands' good management. This project surfaces wetlands through visualisation in a multimodal knowledge platform focusing on two urban renewal sites, Green Square and Marrickville South. We leverage design ethnography to develop resources for strengthening multiple stakeholders’ socioecological engagement through methods empowering just, creative and open participation.Read moreRead less
An in-built depolymerisation solution for polyethylene waste. This project aims to design enzymes that can be embedded into polyethylene, and later activated by the elevated temperatures of a compost heap, to depolymerise the plastic to small molecules. There are no good options available for the controlled decomposition of polyethylene waste at present, and instead researchers have focussed on solutions that rely on modifications to the underlying chemistry of the backbone and or collection to ....An in-built depolymerisation solution for polyethylene waste. This project aims to design enzymes that can be embedded into polyethylene, and later activated by the elevated temperatures of a compost heap, to depolymerise the plastic to small molecules. There are no good options available for the controlled decomposition of polyethylene waste at present, and instead researchers have focussed on solutions that rely on modifications to the underlying chemistry of the backbone and or collection to a central facility. Our approach would result in an in-built decomposition that does not require collection and recycling in a central facility. Since it is based on a depolymerisation mechanism it does not result in the production of harmful, partially disintegrated microplastics.Read moreRead less
