Blocking of the interfaces of polymeric ion sensors - implications for novel sensor applications. Control of the transmembrane fluxes of polymeric ion sensors represents a paradigm shift that has revolutionised the use of these analytically important devices. This project will develop and characterise innovative methods for controlling these fluxes by using blocked interfaces, and this has important ramifications for the development of robust and reliable sensors, as well as novel biosensors.
Energetics and dynamics of solvated biologically relevant molecules using liquid microjet and ion imaging technologies. The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule. Many experiments have informed u ....Energetics and dynamics of solvated biologically relevant molecules using liquid microjet and ion imaging technologies. The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule. Many experiments have informed us about the strength of the bonds, others have told us where the bonds occur. This project will provide both pieces of information for the first time, allowing us to better understand, and therefore control, biological function. This work will assist in the development of new biotechnology processes, especially in the emerging area of proteomics.Read moreRead less

Crystal engineering is an exciting modern branch of chemistry that seeks to understand intermolecular interactions in the context of crystal packing, and to use this understanding in the design of new materials with desirable physical and chemical properties. This project will considerably extend our already significant contribution to the detailed analysis of intermolecular interactions in molecular crystal structures. It will achieve this by a substantial enhancement of our novel visualization tools, by improving upon current approaches to the analysis of theoretical and experimental crystalline electron distributions for molecular materials, and by ensuring the widespread availability of resulting software to all researchers.Read moreRead less

This project will make a novel contribution towards the creation and optimisation of new optically-active materials, an objective central to future photon science and information technology. By developing and implementing innovative approaches in the charge density analysis of high-resolution, low-temperature single-crystal X-ray diffraction data, we will obtain in-crystal estimates of the electronic part of molecular (hyper)polarisabilities and related bulk susceptibilities, for crystals of selected important organic nonlinear optical (NLO) materials. The program will exploit advances in CCD technology for X-ray data collection, procedures for electron density and wavefunction fitting, and analysis of molecular dynamics in crystals.Read moreRead less

This proposal seeks funds for the purchase and installation of a state-of-the-art 400 MHz Wide-Bore Solid-State NMR spectrometer. Research projects utilising this euipment will benefit from the ability to probe the structure of solid samples that are difficult to characterise in any other way. These materials represent advances in nanotechnology, new materials and will impact on the analysis of environmental contaminants in potable water supplies, with a particular Australian focus on the identification of compounds formed as by-products during disinfection processes.
The upgraded facility will be the only one of its kind in Western Australia.

However, major productivity gains are required for Australian producers to remain globally competitive. More accurate thermodynamic calculations, covering the full plant operating range, are seen by the industry as an important way to increase productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must extend current theoretical understanding and establish an experimental capability, hitherto unavailable in Australia, for measuring heat capacities and densities of solutions to temperatures as high as 300 C.Read moreRead less
