The objective of this project is the discovery of novel methods for the treatment and reuse of water for both industrial and household applications. Improved treatment systems with the potential for water reuse offer significant improvements to our overall water management potential. The first part of the project is designed to focus on the study of hot bubble column evaporators for solute decomposition, sterilisation and the de-watering of heavily contaminated industrial wastewater. The second part would be based on the study of a suitable depth filter medium for the treatment of partially treated household sewage water. This is designed to form part of an on-site household sewage water treatment and reuse system which is currently being developed.Read moreRead less
Accurate and fast quantum simulation to predict chemistry. Quantum mechanical simulation is the most accurate tool available for predicting and understanding chemical reactions. Traditional techniques for performing quantum mechanical simulations of molecular collisions and reactions cannot be applied to more than five or six atoms, meaning that it is not possible to study most chemical reactions in full detail. In this project a new technique for performing these accurate simulations, recently ....Accurate and fast quantum simulation to predict chemistry. Quantum mechanical simulation is the most accurate tool available for predicting and understanding chemical reactions. Traditional techniques for performing quantum mechanical simulations of molecular collisions and reactions cannot be applied to more than five or six atoms, meaning that it is not possible to study most chemical reactions in full detail. In this project a new technique for performing these accurate simulations, recently invented at the Australian National University and allowing the study of much larger systems, will be developed and applied to important outstanding problems in chemical dynamics, ranging from roaming in formaldehyde to atom migration in proteins.Read moreRead less

The role of low-energy excited states in solar-energy capture. This project aims to determine the nature and role of the lowest-energy excited states in most natural photosynthetic reaction centres and light-harvesting complexes. The lowest-energy states of bacterial reaction centres are critical to function and are used as a paradigm in artificial organic solar-energy capture, but for most photosystems their nature remains unknown. The project aims to answer the critical question of why they do ....The role of low-energy excited states in solar-energy capture. This project aims to determine the nature and role of the lowest-energy excited states in most natural photosynthetic reaction centres and light-harvesting complexes. The lowest-energy states of bacterial reaction centres are critical to function and are used as a paradigm in artificial organic solar-energy capture, but for most photosystems their nature remains unknown. The project aims to answer the critical question of why they do not actually prevent function. It is expected that both the outcomes obtained and techniques developed will be directly relevant to solar-energy device design. The project will apply five existing, complimentary and purposely built spectrometers as well as quantum electronic and nuclear simulation techniques to identify and characterise three key systems.Read moreRead less
Deciphering ion specificity in complex electrolytes . This project aims to understand how ions influence the behaviour and properties of complex electrolytes (solutions containing either multiple ions, solvent mixtures, high electrolyte concentrations or a variety of interfaces, solutes or polymers).

Unravelling the dominant drivers of ion specificity. This project aims to understand what governs the sensitivity of many technological and biological processes to the precise nature of the salt present in solution. The term ‘ion-specific’ encompasses all the circumstances in which the influence of a salt in solution depends on the precise chemical nature of the salt, not just the electrical charge on the ions that form the salt. As such, ion-specific effects abound and have important consequenc ....Unravelling the dominant drivers of ion specificity. This project aims to understand what governs the sensitivity of many technological and biological processes to the precise nature of the salt present in solution. The term ‘ion-specific’ encompasses all the circumstances in which the influence of a salt in solution depends on the precise chemical nature of the salt, not just the electrical charge on the ions that form the salt. As such, ion-specific effects abound and have important consequences in most situations involving solutions, including cellular functions and battery technology. This project will enable us to understand and control the influence of specific ions, building on our recently described fundamental ion-specific series with colloid science experiments and quantum simulations. This project should overcome current challenges in predicting ion-specific effects leading to progress in a wide variety of applications of colloid and interface science, from sensor interfaces to self-assembly.Read moreRead less

Boron and silicon based pincer ligands for environmentally responsible catalysis. The production of everyday chemicals (pharmaceuticals, agrochemicals, polymers) comes at a price, economic and environmental. Metal catalysts significantly reduce the environmental impact of both the associated energy requirements and waste products. New classes of catalysts will be developed based on the unconventional elements boron and silicon.
Nanorheology: Hydrodynamic Slip in Newtonian Fluids. Understanding fluid flow across a surface is essential to a great number of technologies. For over one hundred years it has been assumed that the layer of fluid adjacent to the solid moves with the solid, this is known as the no-slip boundary condition. Recently direct force balance measurements of aqueous Newtonian solutions have indicated the presence of boundary slip. Using a newly developed nanorheology technique we will systematically inv ....Nanorheology: Hydrodynamic Slip in Newtonian Fluids. Understanding fluid flow across a surface is essential to a great number of technologies. For over one hundred years it has been assumed that the layer of fluid adjacent to the solid moves with the solid, this is known as the no-slip boundary condition. Recently direct force balance measurements of aqueous Newtonian solutions have indicated the presence of boundary slip. Using a newly developed nanorheology technique we will systematically investigate the conditions that control boundary slip. This information will be used to quantify, model and control boundary slip, progressing the fields of microfluidics, particle deposition, and colloid stability.Read moreRead less
