Self-Organised 3-D Arrays of Stimulus Responsive Block Copolymer Micelles. At the core of developments in nanotechnology is a desire to manufacture functional devices from molecular or colloidal building blocks. A significant component of this effort is directed at the self-assembly of these materials on solid substrates. Ultimately, the development of higher order functional nanomaterials requires a fine control over the 3-dimensional location of each component; this is a significant problem.

At the core of developments in nanotechnology is a desire to manufacture functional devices from molecular or colloidal building blocks. A significant component of this effort is directed at the self-assembly of these materials on solid substrates. Ultimately, the development of higher order functional nanomaterials requires a fine control over the 3-dimensional location of each component; this is a significant problem. In this project our aim is to develop novel self-assembled surface coatings using block copolymer micelles. Spatial control of the micelle adsorption at the solid-aqueous interface will give us a significant degree of control over molecular location in 3-dimensions.Read moreRead less

Nanotechnology - science at the scale of a billionth of a metre - rests on our ability to manipulate molecules and to build structures that will be part of useful devices. We shall develop new methods to put that chemistry on carbon surfaces - leading to very stable and cheap devices that will have 'real world' applications in environmental monitoring. A 'bottom up' method of fabrication exploits the ability of similar molecules to line up on a suitable surface, so-called 'self Assembly'. The project is based on sound fundamental science for an applied research outcome and therefore will enhance Australian's standing as a strong scientific country that applies its knowledge at the forefront of technological advancement.Read moreRead less

In this project two new fluorous tagging strategies will be investigated in an effort to broaden the scope of reagents that can used in synthesis. Efforts will be directed to chiral auxiliaries and to fluorous catalyst ligands. In addition, a novel class of fluorous surfactant will be investigated, for its surface properties (including its ability to self assemble) and for its utility in two specific applications, selective membrane-bound protein extraction (relevant to proteomics) and ophthalmics (biomaterials).Read moreRead less

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.
