deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

The mechanism of scale formation and inhibition in alkaline industrial process streams. Scaling, which reduces flow and heating efficiency, is a serious problem in single stream alumina Bayer plants. This project will potentially save the Australian alumina industry many tens of millions of dollars a year by the development of more effective on-line scale mitigation strategies based on the fundamental understanding of the processes involved.
Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silic ....Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.Read moreRead less

Electrostatic Catalysis: guiding reactive interfaces using electric fields. This project seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies.

This project seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies. Recent computational studies suggest that by applying oriented electric fields at interfaces, the rate and the selectivity of chemical processes can be altered at will. The project intends to test these theoretical findings. The knowledge generated by this research may translate into new technologies for the fine-chemical and biotechnology industries.Read moreRead less
'Multi-Coloured' Tracers for Magnetic Particle Imaging . Magnetic Particle Imaging (MPI) is predicted to be the future of imaging and will outperform all current imaging techniques by having 'colours', improved resolution and 3D precision.

Magnetic Particle Imaging (MPI) is predicted to be the future of imaging and will outperform all current imaging techniques by having 'colours', improved resolution and 3D precision. This project aims to create 'multi-coloured' high-performance MPI tracers by synthesising a range of the most effective magnetic nanoparticle structures. The expected outcome is the fundamental understanding of the relationships between nanoparticle structures and their magnetic properties for the formation of MPI signals with distinct ‘colours’. The benefits will be a library of MPI tracers that are able to provide ‘coloured’, high intensity, precise signals beyond what can be achieved with other imaging technologies.Read moreRead less

Utilising new Australian research infrastructure the project aims to unlock the complex behaviour across different types of milk (including human breast milk) and infant formulae, linking how enzymes behave towards fat droplets and the consequences for lipid structuring and nutrient transport. The rational design of systems that function much more closely to human milk will enable the development of new products with flow on benefits in human nutrition and increased utilisation of products from our dairy industry.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.

The interaction between metallic nanoparticles creates highly enhanced, localised electric fields and has recently emerged as a strategic area widely applicable across physics, chemistry and biology for sensing, optoelectronics and optical films. The novel optical signatures of larger, highly symmetric nanoparticle assemblies may be drastically changed by breaking the structural symmetry, leading to unique phenomenon such as Fano-like resonances. This project aims to extend metal nanoparticle assemblies to include fluorophores in well-defined positions, creating an inherent and switchable symmetry breaking. Inclusion of additional functionality into such structures is essential for their use in smart optical films and switchable devices.Read moreRead less

Surface active ionic liquids are much more effective than conventional electrolytes for some applications, but only at elevated temperature; at low temperature, ion dynamics are too slow. We will use cutting edge techniques to probe ion dynamics in surface active ionic liquids in the bulk and at electrode surfaces, and use this to elucidate rules for the rational design of new surface active ionic liquids with fast dynamics at low temperature, towards their use at room temperature in diverse areas; this project will target capacitors and gas sensors.
