This project aims to identify meaningful and specific indicators for predicting particle formation and alteration during thunderstorms. How thunderstorms develop is well-understood. However, identifying meaningful and specific indicators for predicting particle alteration during a thunderstorm is still not clear. This project will practically contribute to the evidence of the impact of air particulates, thereby having direct implications for meteorological, and air pollution policy in Australia and worldwide. This project will allow researchers to understand the impact of these factors on the escalation of the causative effects, and to find a way to prevent unnecessary fatal outcomes.Read moreRead less
Breaking emulsions. Droplet coalescence is the key to breaking emulsions, that is, separating oil from water. This process underpins the recovery of crude oil and the remediation of industrial and environmental waste-waters. Through a unique and novel experimental program that simultaneously tracks drop trajectories up to the millimetre scale and drop deformations in the nanometre scale, this project aims to fill a fundamental gap in our understanding of such coalescence events.

This process underpins the recovery of crude oil and the remediation of industrial and environmental waste-waters. Through a unique and novel experimental program that simultaneously tracks drop trajectories up to the millimetre scale and drop deformations in the nanometre scale, this project aims to fill a fundamental gap in our understanding of such coalescence events. A complete theoretical model of coalescence will result, forming a predictive framework for separating emulsions to recover pure oil and water, and laying the foundation for using compound drops to tune the optical properties of surface for speciality applications.Read moreRead less

Shape sorting of nanoparticles at oil-water interfaces in microchannels. This project aims to study the effect of shape on the adsorption of nanoparticles at an oil/water interface and develop a rapid, inexpensive, efficient, versatile method for shape sorting of nanoparticles using a microfluidic approach. This technique can be applied for fractionation of synthetic nanoparticles, biosample analysis and environmental monitoring.

The aim of this project is to develop novel methods for forming robust single-molecule circuitry. The use of single molecules in electronics represents the next level of miniaturisation of electronic components, which would enable us to meet the expanding demands of modern technologies and to continue the downscaling trend in electronic devices. This project aims to address the requirements needed to translate single-molecule electronics from its current status as a fundamental tool to real-world applications. Key approaches will be the use of surface chemistry to develop new methods of wiring single molecules and the integration of robust single-molecule junctions with semiconducting electrodes. The expected project outcomes pave the way for single-molecule electronic and analytical devices.Read moreRead less

From plastics to pharamaceuticals, chemists rely extensively on expensive and environmentally damaging solvents and reactants. In water, greener and cheaper electricity-driven reactions currently suffer from low velocity and poor selectivity. The project aims to develop the science of on-water electrochemistry, to make electricity-driven organic reactions in water viable. Demonstrating that for electrochemical reactions, rates and selectivities increase on water’s surface rather than in its bulk will remove fundamental constraints on the viability of aqueous electro-synthesis – moving beyond current reactor designs to transform our view of electrochemistry and improve the sustainability of the chemical industry.Read moreRead less

The goal of this project is to develop innovative colloidal nanocrystal heterostructures to provide the basis for eco-friendly optoelectronic devices and photocatalysis as well as other advanced applications. One-dimensional semiconductor nanocrystals have desirable electronic and catalytic properties (a linearly polarised emission, large absorption cross section, reduced lasing threshold and improved charge separation and transport). However, present investigations of these materials are mainly limited to highly toxic cadmium chalcogenides. This project aims to explore a family of cadmium-free colloidal nanocrystal heterostructures with the desired properties. The project intends to investigate their growth mechanisms, properties and effects to support product development and advance the fundamental knowledge of electronics at the nanoscale.Read moreRead less
