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.
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.
Harnessing Asymmetry in Hybrid Metal Nanocrystal Assemblies. 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 ....Harnessing Asymmetry in Hybrid Metal Nanocrystal Assemblies. 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

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

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
A new explanation for the hydrophobic effect. The hydrophobic effect is a fundamental natural phenomenon: why do oil and water spontaneously separate and not mix? The project team proposes a new and novel explanation for this effect, based on known properties of water. The project team's theory explains hydrophobic effects in physics, chemistry and biology.
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.

The proposed research will greatly expand research into fluids with complex and valuable microstructures: this includes foods, adhesives, pharmaceuticals, and even blood. Key Australian X-ray and Nuclear facilities provide amazing insights into valuable and exotic material structures every day, but most of these measurements are on static samples. Because flow and mixing is critical to industry and advanced research processes that develop new materials, a facility is needed that allows the same careful study of material structure with the addition of controlled flow. We will build such facilities, enabling study of high-speed, stretching, and other complex flows, matching applied processes and giving Australia the lead in their study.Read moreRead less

The role of fat crystal wettability in altering dairy emulsion properties. This project aims to control fat crystal wettability, to create tailored dairy products with desirable stability, shelf-life and texture. Fat crystals are an essential component of dairy emulsions (fat droplets dispersed in dairy/milk serum) and control product processing, shelf life and texture. Their structuring role involves partial coalescence: the formation of complicated network structures of fat droplets. Unless fat crystals are partially wetted by water, they will not be present at the fat droplet interface, and partial coalescence will not occur. Expected outcomes are new dairy products with optimum stability and texture.Read moreRead less
