Current consumer electronic devices rely on lithium-ion batteries to provide a high energy density power source. There are growing safety concerns about the electrolytes in these devices after recent incidents involving fires in mobile phones. Recent advances in ionic liquids (ILs) have seen the development of new electrolytes for such devices, with enhanced physical properties that offer major safety advantages. However, the viscosity of these materials currently limit their capabilities. New IL materials to be developed in this project will pave the way for the development of safer devices and new sustainable energy industries in Australia.Read moreRead less
Cooperativity in Spin Crossover Systems: Memory, Magnetism and Microporosity. Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism. Here we aim to synthesise and study a wide variety of new spin-crossover systems where cooperativitiy between centres, induced by careful supramolecular design, will lead to molecul ....Cooperativity in Spin Crossover Systems: Memory, Magnetism and Microporosity. Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism. Here we aim to synthesise and study a wide variety of new spin-crossover systems where cooperativitiy between centres, induced by careful supramolecular design, will lead to molecules and materials having memory retention, magnetic ordering and/or microporosity. The significance of these aims covers several fundamental questions in the science of electronic systems. We also identify a number of potential nanochemical switching applications for the unique systems proposed.Read moreRead less

Using novel analytical techniques, this project aims to characterise contaminants found in recycled PET and identify the source(s) of this contamination. Ultimately this will lead to a reduction in recycled PET contamination levels, and allow a more complete recycling process.

Designer Surfactants for Creation of Emulsion Properties. We propose new approaches to the design of surfactants for stabilising water in oil emulsions. New block copolymer surfactants may be "tailored" for head group structure and a pre-chosen hydrophilic/lipophilic balance at the oil-water interface using the Australian developed RAFT polymer synthesis method and polymeric inorganic species. The proposers have an extensive background in these areas.

X-ray and neutron scattering techniques, developed by us, allow the interfacial structure of the surfactant to be found and the intellectual "loop" closed in the design process. Preliminary screening will be done using the surface balance and bulk emulsion synthesis.Read moreRead less

Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mesoscale structure in emulsion formulation, as well as the rheology and stability of emulsion preparations. To do this we plan to use mixed surfactant systems and to study intersurfactant synergic effects on the structure and fluidity of the interfacial material. We believe that the proposed work is unique and that the outcomes will be scientifically novel and also valuable for Australian industry.Read moreRead less
