Computational studies of melting and the solvation properties of ionic liquids. Ionic liquids are used in industry as green solvents and electrolytes, although there is not yet sufficient knowledge on the science of ionic liquids to enable optimal solvents to be readily designed. This project uses state of the art techniques in computational chemistry to solve practical problems related to the characteristics of ionic liquids.
Functional Materials from Weakly-Structured Self-Assembly Fluids. This project seeks to understand how mixtures of simple molecules can form complex structured liquids. Such mixtures occur widely both in nature and industrial settings. By using an approach combining new, high-resolution experimental techniques with computer modelling, it is expected that a detailed picture of molecular arrangements in these liquids will be obtained, allowing the relationship between composition, structure and pr ....Functional Materials from Weakly-Structured Self-Assembly Fluids. This project seeks to understand how mixtures of simple molecules can form complex structured liquids. Such mixtures occur widely both in nature and industrial settings. By using an approach combining new, high-resolution experimental techniques with computer modelling, it is expected that a detailed picture of molecular arrangements in these liquids will be obtained, allowing the relationship between composition, structure and properties to be understood for the first time. The new understanding of molecular arrangements within liquids may be used to design new solvents for chemical synthesis and catalysis, new food, personal care and pharmaceutical formulations, and new, smart materials that change their properties under external stimulus.Read moreRead less
Hofmeister at work. Implementation of a paradigm shift in physical chemistry. Standard tools of measurement in environmental, industrial, colloid, nano and biosciences rest on classical theories which have been shown to be badly flawed. The faults have been remedied to give a new, predictive and usable foundation that amounts to a paradigm shift of immediate importance to many applications.
Algorithms for multi-scale problems in science and engineering. This project aims to develop theoretical formulations and algorithms for modelling fundamental problems in molecular electrostatics, dispersion force theory, acoustics and electromagnetic scattering in applications where current approaches may be useless. Many engineering applications, from microelectronics to bioengineering devices, need to operate across dimensions from a few millimetres down to a million times smaller. This large ....Algorithms for multi-scale problems in science and engineering. This project aims to develop theoretical formulations and algorithms for modelling fundamental problems in molecular electrostatics, dispersion force theory, acoustics and electromagnetic scattering in applications where current approaches may be useless. Many engineering applications, from microelectronics to bioengineering devices, need to operate across dimensions from a few millimetres down to a million times smaller. This large range of length scales means traditional modelling tools and computational techniques will rapidly become intractable. This project will meet this need to strengthen the Australian technological skill base and contribute to innovations in areas ranging from bioengineering to nanotechnology.Read moreRead less

Summary
Human albumin solution is widely used for the emergency treatment of severely ill patients requiring fluid replacement, both in Australia and worldwide. However, a recent report suggests that compared to the other standard treatment (salt solution), the use of human albumin solution may be associated with a higher death rate (about six additional deaths among every one hundred patients treated). But, this report was based on data from a relatively small number of patients among whom there was a ....Human albumin solution is widely used for the emergency treatment of severely ill patients requiring fluid replacement, both in Australia and worldwide. However, a recent report suggests that compared to the other standard treatment (salt solution), the use of human albumin solution may be associated with a higher death rate (about six additional deaths among every one hundred patients treated). But, this report was based on data from a relatively small number of patients among whom there was a relatively small number of deaths, and there is widespread uncertainty among doctors about the reliability of the evidence and the implications for patient care. This is reflected in the large difference between intensive care units in the use of human albumin solution (in Australia, its use ranges from 10-90% of all patients needing fluid). Human albumin solution costs, about thirty times more than salt solution, and during 1998 more than 200,000 bottles of human albumin solution were administered to patients in Australia, at a cost of about A$35 million. In an effort to provide definitive evidence about the effects (and cost-effectiveness) of fluid replacement with human albumin solution, the Australia and New Zealand Intensive Care Society, in collaboration with the Australian Red Cross Blood Services and the Institute for International Health, has proposed the conduct of new large-scale study (SAFE - Saline vs Albumin Fluid Evaluation). This study will involve 7,000 patients from 15 intensive care units in Australia and New Zealand. These patients (all of whom require fluid replacement) will be randomly assigned to receive either human albumin solution or salt solution and outcome in terms of deaths and other serious events will be monitored over 28 days. Results will be available within 2 years of starting the study, and these are likely to influence the care of the majority of seriously ill patients admitted to intensive care units worldwide.Read moreRead less
Hypertonic Saline (HTS) In Head Injured Patients - A Multicentre, Prehospital, Prospective Randomised Clinical Trial

Summary
Head injury is common in patients with major trauma, many of whom are young adults. The extent of head injury has a major influence on patient outcome. Low blood pressure after trauma worsens the extent of brain injury by decreasing its blood supply at a critical stage. Much of this secondary brain injury occurs before the patient reaches hospital. Hypertonic saline (HTS) is an intravenous salt solution which has been used in intensive care patients for many years to decrease brain swelling in h ....Head injury is common in patients with major trauma, many of whom are young adults. The extent of head injury has a major influence on patient outcome. Low blood pressure after trauma worsens the extent of brain injury by decreasing its blood supply at a critical stage. Much of this secondary brain injury occurs before the patient reaches hospital. Hypertonic saline (HTS) is an intravenous salt solution which has been used in intensive care patients for many years to decrease brain swelling in head injured patients. We know that HTS can be given to patients before they reach hospital, is safe, and acts by rapidly increasing blood pressure and decreasing brain swelling. Accordingly HTS may minimise secondary brain injury and lead to increased survival. Importantly, HTS is likely to dramatically improve neurological function of survivors without any significant risk of side effects. This study is designed to determine the effectiveness of prehospital HTS in head injured trauma patients with traumatic coma and low blood pressure.Read moreRead less
A study of some physical properties of concentrated salt solutions. The foam we see on the sea shore is caused by the effects of salt in seawater and is one example of the unusual properties of water. These effects can be applied to understand and improve several important processes, such as, boiling, desalination and the precipitation of fine particles from concentrated salt solutions.

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
