Molecules as probes of the interstellar medium. It is one of the greatest challenges in Nature is to remotely identify what is in space. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown, implying that there are many more molecules in space than we know about. With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab. Conversely, identification of these features will provide the tools to u ....Molecules as probes of the interstellar medium.

With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab. Conversely, identification of these features will provide the tools to understand interstellar chemistry. In this project we combine skills in spectroscopy and astronomy to make these molecules in the laboratory, measure their spectra and thereby identify unknown molecules in space.Read moreRead less
Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operati ....Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operation and seeking cures for diseases caused by their malfunction. This project aims to develop accurate ion-protein-water interactions for permeation models based on stochastic and molecular dynamics simulations using both classical and quantum mechanical methods.Read moreRead less
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

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). Complex electrolytes are ubiquitous in colloidal and particle technologies and underpin industrial and natural processes.

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). Complex electrolytes are ubiquitous in colloidal and particle technologies and underpin industrial and natural processes. Our team will combine experiment, simulation and theory to deliver a universal framework for understanding and predicting specific ion effects in complex electrolytes.

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
The First Deep Infrared Study of the Nearby Galaxy Population. We will conduct two major near-infrared (IR) surveys: The Southern Galactic Cap near-IR survey, and the Local Sphere of Influence survey. These surveys will capitalise on the innovative and award winning Australian IRIS2 facility. The two surveys push the observational frontier by orders of magnitude. They will be used to explore the close connection between the near-IR global properties of a galaxy and its underlying physics and pro ....The First Deep Infrared Study of the Nearby Galaxy Population.

These surveys will capitalise on the innovative and award winning Australian IRIS2 facility. The two surveys push the observational frontier by orders of magnitude. They will be used to explore the close connection between the near-IR global properties of a galaxy and its underlying physics and provide a generic local reference for the upcoming next generation infrared space-telescope missions.

Observations of hydrogen gas have long been recognised as a key to following galaxy formation and evolution, and they are a key driver for building the Square Kilometre Array telescope, a project which could be sited in Australia. The SKA project is a multi-billion dollar project, which would bring international recognition and prestige. Development of the scientific expertise to motivate this project is an important part of establishing Australia's leadership role.Read moreRead less

RAVE will use a new-technology Australian fiber spectrometer at the Siding Spring UK Schmidt Telescope. A key demonstrator for RAVE is our proposed pilot survey using existing instruments to measure 100,000 stars - already 20 times larger than any previous survey - providing unique chemical and kinematical fingerprints of our Galaxy's formation. This is critical for determining the optimum observing strategy, data management, and software pipeline, before embarking on the full survey in 2006.Read moreRead less

This project will enhance this reputation by using the new AAOmega facility on the 3.9m Anglo-Australian Telescope to make the largest ever survey of galaxies in the distant universe. This will allow us to address the two most important issues in cosmology today - the nature of the "dark energy" that is causing the universe's expansion to accelerate, and the detailed role of dark matter in galaxy formation and evolution.
