Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the pre ....Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the present project we shall develop suitable numerical techniques for solving the fractional order diffusion model, and apply these to the interpretation of experimental kinetic data. The outcome will be an improved model of adsorption dynamics considering the fractal nature of the solid.Read moreRead less
Development of an Adjustable Porphyrin-based Molecular Platform for Nanotechnology Applications. Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level. Our control is realised through a process called self-assembly which means that the once the components of the device are correctly designed, the device will simply be able to put itself tog ....Development of an Adjustable Porphyrin-based Molecular Platform for Nanotechnology Applications. Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level. Our control is realised through a process called self-assembly which means that the once the components of the device are correctly designed, the device will simply be able to put itself together. This research will use nature's light harvesting elements, namely porphyrins, and our ability to precisely control their position with respect to each other to build new, more efficient solar cells.Read moreRead less
Modelling of Adsorption Dynamics in Microporous Solids based on Molecular Dynamics Computations. This project seeks to incorporate non-equilibrium molecular dynamics calculations into particle scale models for adsorption kinetics. Molecular dynamics calculations will be performed for hydrocarbon molecules in small pores to obtain transport coefficients in pores of various sizes, at various bulk gas pressures and temperatures. These transport coefficients will be used in particle scale models t ....Modelling of Adsorption Dynamics in Microporous Solids based on Molecular Dynamics Computations. This project seeks to incorporate non-equilibrium molecular dynamics calculations into particle scale models for adsorption kinetics. Molecular dynamics calculations will be performed for hydrocarbon molecules in small pores to obtain transport coefficients in pores of various sizes, at various bulk gas pressures and temperatures. These transport coefficients will be used in particle scale models to obtain a dynamic model, which will be utilised to interpret experimental data from the literature as well as that being obtained in our laboratory. Such first principles-based modelling has not been performed before at the particle scale, and will mitigate the empiricism in existing approaches.Read moreRead less

Leading edge research will enable state of the art techniques in statistical mechanics to be applied to practical problems. All processes in biological, chemical and physical systems are governed by their free energy landscape, often only accessible computationally. This project will lead to an advanced tool for free energy calculation. Advancement of emerging technologies in nanoscience, porous materials, membrane transport and drug design will benefit from this capability. The project therefore addresses the Priority Goal 'Breakthrough science'. A PhD student and an Early Career Research will be trained in research, gaining a range of valuable skills in theory and simulation. Read moreRead less
Spin-liquids, antiferromagnetism, and superconductivity in organic charge transfer salts: synthesis, neutron scattering and theory. Materials have driven the digital revolution. Understanding and controlling silicon has allowed us to make smaller devices that perform better; an iPhone has more computing power than a PC had ten years ago.

Materials have driven the digital revolution. Understanding and controlling silicon has allowed us to make smaller devices that perform better; an iPhone has more computing power than a PC had ten years ago. For this remarkable trend to continue future devices will need to utilise novel physics and be made from new materials. We will grow crystals of organic molecules, whose properties derive from the correlated motion of the electrons in these materials. State-of-the-art 'neutron scattering' experiments will test theories of the way the electrons behave in these materials. We will answer fundamental questions, which is an important first step towards harnessing such effects for future technology.Read moreRead less

Dendrimers: multidimensional sensors. The threat of terrorism is presented to us on a daily basis. Although there is often talk of dirty bombs, and biological and nuclear terrorism, the most easily sourced weapon of the terrorist is still the conventional explosive. As such the ability to detect trace amounts of compounds such as TNT or Semtex is required. This means that there is a real need for a portable detection system with the ability to reliably sense a specific explosive, selectively at ....Dendrimers: multidimensional sensors. The threat of terrorism is presented to us on a daily basis. Although there is often talk of dirty bombs, and biological and nuclear terrorism, the most easily sourced weapon of the terrorist is still the conventional explosive. As such the ability to detect trace amounts of compounds such as TNT or Semtex is required. This means that there is a real need for a portable detection system with the ability to reliably sense a specific explosive, selectively at low concentrations. This project concerns the development of new sensors that have potential to increase the nation's security.Read moreRead less

This initiative will build an active, dynamic and strongly interdisciplinary network of young Australian scientists (most awarded their Ph.D. after 1985) working on the development of innovative electronic devices - a national research priority area with enormous economic and technological opportunity. The network will enable a nationally coordinated, internationally competitive approach that capitalizes on untapped opportunities, utilises existing/emerging Australian expertise and develops strong supporting links with similar networks overseas. The initiative will produce a public showcase of Australian strengths and opportunities in this field, and enable stronger collaborations and cooperative logistics management through the development of a dedicated network management website.Read moreRead less
Fluctuations in the properties of nonequilibrium fluids and the influence of thermostatting mechanisms. The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also ....Fluctuations in the properties of nonequilibrium fluids and the influence of thermostatting mechanisms. The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also applicable to microscopic systems. The expressions will determine the probability that finite sized systems will violate the Second Law for small periods of time and will therefore contribute to development of a fundamental understanding of microscopic systems and the development of nanotechnology.
