Selective Detection and Removal of Contaminants That Have an Adverse Impact on Australian Raw Sugar Quality. Sugar is Australia's 2nd largest agricultural crop with 80-85% exported earning $2 billion in export revenue. Whilst Australia is arguably the most reliable supplier of premium raw sugar the implementation of improved processing technologies by rivals has (and without appropriate research strategies will continue to) eroded some of the long-held Australian advantages.

Sugar is Australia's 2nd largest agricultural crop with 80-85% exported earning $2 billion in export revenue. Whilst Australia is arguably the most reliable supplier of premium raw sugar the implementation of improved processing technologies by rivals has (and without appropriate research strategies will continue to) eroded some of the long-held Australian advantages.
Our innovative approaches will improve raw sugar quality, measurement methods, and allow new product development (value adding), enabling Australia to maintain its? world leading position. Importantly, our technologies enable improvements of specific quality issues (and potentially as yet unidentified issues), further differentiating the Australian product in the international marketplace.

Novel Synthetic Receptors For Selective Recognition of Phosphate Oxoanions. Anions are critical to the maintenance of life, playing roles in almost every biochemical process. Artificial anion receptors that bind strongly to specific anions have considerable potential applications in biomedicine, but current receptors do not possess the required selectivity for applications. We will undertake the design and construction of a number of molecular receptors tailored to complement the size, shape and ....Novel Synthetic Receptors For Selective Recognition of Phosphate Oxoanions. Anions are critical to the maintenance of life, playing roles in almost every biochemical process. Artificial anion receptors that bind strongly to specific anions have considerable potential applications in biomedicine, but current receptors do not possess the required selectivity for applications. We will undertake the design and construction of a number of molecular receptors tailored to complement the size, shape and charge of specific biologically important anions and will assess their ability to bind selectively to their target guests. This will lead to the development of small molecule receptors for use in biomedical applications.Read moreRead less
Backbone Modified Cyclic Peptides: Scaffolds for Supramolecular Chemistry. The synthesis of compounds that mimic Nature's catalysts - enzymes - will provide us with a better understanding of how these intriguing molecules function and may lead to the development of new catalysts for industrial processes. Modified cyclic peptides could be used as platforms to arrange catalytic groups in a spatially well-defined manner to mimic enzymes. As cyclic peptides are often difficult to prepare, I aim to d ....Backbone Modified Cyclic Peptides: Scaffolds for Supramolecular Chemistry. The synthesis of compounds that mimic Nature's catalysts - enzymes - will provide us with a better understanding of how these intriguing molecules function and may lead to the development of new catalysts for industrial processes. Modified cyclic peptides could be used as platforms to arrange catalytic groups in a spatially well-defined manner to mimic enzymes. As cyclic peptides are often difficult to prepare, I aim to develop a powerful general method for their synthesis. This methodology will then be applied to the synthesis of cyclic peptide-based enzyme mimics.Read moreRead less
Nanomaterials: Probing supramolecular self-assembly at the solution/solid interface. Australia's competitiveness in nanotechnology must be underpinned by fundamental innovation and research. In a "bottom-up" approach to nanomaterials, it is important to understand, for the smallest possible machines that can be produced, how singular molecular components interact with one another, both during the assembly of any device and afterwards as it performs its function. For working devices the molecule ....Nanomaterials: Probing supramolecular self-assembly at the solution/solid interface. Australia's competitiveness in nanotechnology must be underpinned by fundamental innovation and research. In a "bottom-up" approach to nanomaterials, it is important to understand, for the smallest possible machines that can be produced, how singular molecular components interact with one another, both during the assembly of any device and afterwards as it performs its function. For working devices the molecules need to be assembled on a solid surface so that they can work in unison. In this project, in conjunction with researchers at the University of Cambridge, we use the new technique of gel-phase NMR spectroscopy to understand the factors involved as molecular components assemble on the surface of polystyrene beads.Read moreRead less
