The use of novel electrolytes based on ionic liquids will be investigated with a view to developing efficient means of titanium (Ti) recovery and purification. The nature of the electrolyte used as well as the electrode substrate and the electrochemical parameters will be optimised with a view to achieving Ti deposits of high purity or Fe-Ti alloys of controlled composition. The effect of these parameters on the morphology of the deposits obtained will be determined. The products obtained here are expected to find application in construction industries and for energy storage.Read moreRead less

Summary
Solar energy conversion: illuminating the origin of long-lived charge-separated states in organic donor/acceptor blends. The origin of exceptionally long-lived charges in organic donor/acceptor solid-state blends will be established. This will substantially enhance the efficiency and commercial viability of applications that rely on these long-lived charge-separated states, such as organic solar cells.
Hot exciton dissociation in donor / acceptor organic solar cells: breaking the efficiency limit of organic photovoltaics. Australia will benefit from this project in several key areas with immediate impact. The development of an innovative solar cell architecture through the use of hot exiton dissociation will deliver a potential increase in the maximum achievable power conversion efficiency. The experimental results will significantly advance fundamental knowledge of organic solar cells.

Australia will benefit from this project in several key areas with immediate impact. The development of an innovative solar cell architecture through the use of hot exiton dissociation will deliver a potential increase in the maximum achievable power conversion efficiency. The experimental results will significantly advance fundamental knowledge of organic solar cells. This has significant economic benefits by making these solar cells more affordable and also opening up the opportunity to use new materials unconstrained by existing proprietary interests. The training of personnel will contribute towards solving the biggest challenge facing the solar industry in Australia: lack of skilled personnel in a highly specialised industry.Read moreRead less
Design of adsorbents for kinetic separation of gases. The purpose of this project is to design, synthesise and test a new family of adsorbents for separation of gas mixtures of environmental and energy significance. The outcome will be a thorough understanding of diffusion in adsorbents and preparation of several candidate adsorbents with superior separation characteristics.

X-ray wavefunction refinement provides a novel approach to the determination of reliable chemical properties through an amalgamation of x-ray diffraction data and ab initio calculations. Detailed knowledge of these properties will greatly improve our understanding of reactivity and selectivity control in chemical processes, two of the most important and challenging questions in chemistry. This project involves the synthesis of hypercoordinated molecules that serve as sterically frozen intermediates along the pathways of nucleophilic substitution reactions. Comparison of their properties with those of textbook compounds will provide a direct link to the classical Lewis notion of bonding and show that the concept of hypervalency is obsolete.Read moreRead less
Future electrochemical energy storage technologies. New rechargeable batteries will be developed through the use of breakthrough electrolytes based on liquid salts. These batteries are vital for the widespread use of renewables in Australia's electricity grid. They will also enable new generations of environmental sensor technology.
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.

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

Observations of wavelike energy transport in photosynthetic systems have exposed the role of quantum mechanics in natural light harvesting. This project is a study of how light harvesting functions for an incoherent source like sunlight. In sunlight, energy transport occurs at steady state, a dramatically simpler regime than when a coherent source like lasers are used. This project will exploit this simplification to develop new methods for treating light harvesting in sunlight and apply them to a variety of natural and artificial systems. It will clarify how bacteria and plants harvest sunlight and lead to design principles that will enable artificial light harvesting to take advantage of quantum effects.Read moreRead less
