Nanoscale Dynamics and Structure of SAILs at Electrodes. This project will produce new, high performance, surface active ionic liquids. Surface active ionic liquids are pure salts in which one of the ions is based on a surfactant molecule. 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.

This project will produce new, high performance, surface active ionic liquids. Surface active ionic liquids are pure salts in which one of the ions is based on a surfactant molecule. 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.

On-water electrochemistry: redox catalysis at the water surface. 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 ....On-water electrochemistry: redox catalysis at the water surface. 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

Wastewater treatment in regional Australia faces challenges of odour control, poor pollutant and pathogen removal, and greenhouse gas emissions. This project aims to innovatively use iron salts to realise highly efficient wastewater treatment in regional areas. With Partner, Western Australia Water Corporation, this project expects to leverage a recent breakthrough discovery on iron chemistry to co-develop and field test a solar system that doses wastewater with iron, to overcome four challenges and a supply chain issue simultaneously. Expected outcomes include industry capacity to adopt and commercialise a novel technology with important global relevance. Outcomes should reduce the inequity of wastewater services in regional Australia.Read moreRead less

Nano-scale modification of gold surfaces for sensing mercury from gaseous effluents of alumina refineries. The Australian alumina industry contributes more than $5.4 billion export income annually. It is also a major driver of the rural economy with all but one of Australia's seven alumina refineries located in rural areas.

The Australian alumina industry contributes more than $5.4 billion export income annually. It is also a major driver of the rural economy with all but one of Australia's seven alumina refineries located in rural areas. In response to the industry's attempts to reduce the environmental impact of its processes, this project will conduct basic strategic research into the interaction between mercury vapour and gold surfaces at the nano-level. Our principal aim is to develop mercury sensor technology suited to alumina refineries. This innovative technology will be a significant breakthrough in the control of mercury emissions and have many other applications.

Globally, and particularly in Australia, water supply and water pollution is one of the most critical constraints to our health and growth. This project seeks to validate a new portable remediation system suitable for deployment at regional locations through the integration and development of advanced sensors. We aim to develop the world’s first completely integrated platform for monitoring both water chemistry and microbiology to provide near-real-time information regarding the quality of the remediated water. We expect this to improve the availability of regional water resources by providing a low-cost remediation solution with integrated monitoring to provide assurances of meeting the Australian Guidelines for Water Recycling (2006).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
