The mechanism of scale formation and inhibition in alkaline industrial process streams. Scaling, which reduces flow and heating efficiency, is a serious problem in single stream alumina Bayer plants. This project will potentially save the Australian alumina industry many tens of millions of dollars a year by the development of more effective on-line scale mitigation strategies based on the fundamental understanding of the processes involved.

Summary
Lignin in ionic liquids: electrochemical approaches towards delignification and depolymerisation. Wood contains a wealth of biomaterials, such as cellulose which can be used to make biofuel and lignin which can be used to make pharmaceuticals. Separating out the cellulose is essential yet difficult, plus lignin must be broken up into smaller fragments; this project will look at using electrochemistry to achieve these processes more efficiently.
Driving Chemical Reactions by Visible and Ultraviolet Light on Supported Noble Metal Nanoparticles. This project will develop advanced materials of noble metal nanoparticles on a support, which can absorb visible and ultraviolet light and catalyse chemical reactions. Such photocatalysts provide the potential to use sunlight, an abundant, green energy source, to drive reactions at ambient temperatures for chemical synthesis and environmental protection.
Upgrading of light gas-to-liquid products to fuels and chemicals. The conversion of natural gas to liquid fuels (gasoline and diesel) is seen as an important alternative to crude oil refining in Australia, and a new industry based around this is likely to emerge in the coming years. This project aims to develop methods by which some of the less valuable by-products can be upgraded to fuels and chemicals.

Summary
Computational Discovery & Design of New Catalytic Halogenophilic Reactions. Computational chemistry will be used to discover and predict new halogenophilic (halogeno = halogen; philic = like) substitution reactions (SN2X) catalysed by positively charged (cationic) catalysts. SN2X is a less known substitution reaction compared to accepted textbook nucleophilic (nucleo = electron-rich) substitution reactions. This proposal capitalises on previous theoretical-experimental understanding of a cation- ....Computational Discovery & Design of New Catalytic Halogenophilic Reactions. Computational chemistry will be used to discover and predict new halogenophilic (halogeno = halogen; philic = like) substitution reactions (SN2X) catalysed by positively charged (cationic) catalysts. SN2X is a less known substitution reaction compared to accepted textbook nucleophilic (nucleo = electron-rich) substitution reactions. This proposal capitalises on previous theoretical-experimental understanding of a cation-catalysed SN2X to develop new chemical reactions using SN2X synthetic strategies to access difficult-to-make molecules of potential medicinal relevance with heavily substituted carbon-carbon and carbon heteroatom bonds.

Signature of vibrational motions encoded into small polyatomic spectra. Using revolutionary state-of-the-art spectrometers, the project plans to search for signatures of large-amplitude vibrational motions that transform one chemical species to another. Bond-breaking chemical reactions necessarily involve highly vibrationally excited reactants and/or products that move the energy of the system away from equilibrium. It is now possible for direct measurements to be made of the changes that a mole ....Signature of vibrational motions encoded into small polyatomic spectra. Using revolutionary state-of-the-art spectrometers, the project plans to search for signatures of large-amplitude vibrational motions that transform one chemical species to another. Bond-breaking chemical reactions necessarily involve highly vibrationally excited reactants and/or products that move the energy of the system away from equilibrium. It is now possible for direct measurements to be made of the changes that a molecule undergoes as it transits across a chemical potential energy barrier. The project plans to examine the long-standing problem of vinylidene-acetylene isomerisation in order to verify the long-suspected existence of large amplitude vibrational motion in small molecules, which are thought to be the signatures of a particular class of chemical dynamics. These would provide a rational basis for future control of unimolecular chemical reactions.Read moreRead less
On-water catalysis for green chemistry. The on-water effect enables acid-catalysed organic reactions to be conducted as emulsions in water, instead of dissolved in expensive and often toxic organic solvents. This research will define the scope and limitations of the effect, allowing predictions about the extent of its applicability in green chemistry using water and renewable feedstocks.
Nano-engineered multi-functional materials for catalysis and sensing by an integrated chemical and electrochemical approach. This project aims to deliver a facile and cheap method to produce a class of nanostructured materials to be used in applications which will have environmental and social benefits such as: green synthesis of fine chemicals, catalyst development for clean energy fuel cells and sensor technology for the detection of potent biotoxins.
