Pulsed oscillating mass analyser. Mass spectrometers are ubiquitous components in chemical analysis, but are often large and expensive. We have developed a new method for mass analysis, which is smaller and cheaper than existing technology. However, the analyser needs further research to determine whether it has the performance specifications to match the other technologies. The objective of this research is to characterise, explore and extend the prototype and to develop the appropriate math ....Pulsed oscillating mass analyser.

Success in this project may lead to a new mass analyser that can be incorporated into analytical instruments, many of which are manufactured in Australia.Read moreRead less

This project aims to transform the understanding of the structure and function of the brain as a complex physical system. It aims to reveal and unify new aspects of information processing, transitions in conscious state, and nonlinear brain interactions by translating and applying concepts and methods from physics and mathematics. It will treat brain structure and dynamics together to address emergent phenomena like waves and patterns on multiple scales, treating waves as equal participants alongside neurons. Innovative predictions of brain phenomena will aim to be verified against data and used to understand brain networks, dynamics, and the physical phenomena underlying information processing and consciousness.Read moreRead less

Photonics, a key research strength in Australia, emerged from the telecommunications industry. But this exciting field has now begun to foster new scientific disciplines. One of the most recent is astrophotonics, a field at the interface of photonics and another Australian research strength, astronomy. Astrophotonics will deliver cutting-edge technologies to ensure Australia's astronomical lead in the next decade. These new facilities will serve as a vital stepping stone to the Giant Magellan Telescope, a $500M project promising enormous economic, engineering and scientific opportunities for Australia. Astrophotonics will also lead to innovative technology transfer to fields such as medical science, optical computing and sensor technology.Read moreRead less
Characterisation of two-pore domain potassium channels: structure-function studies of the M1-P1 loops of TASK channels. TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers.

TWIK-related Acid Sensitive K+ (TASK) channels are members of the novel class of two-pore domain potassium channel family. They are potently inhibited by local anaesthetics and have been implicated as having important roles in many pathophysiological conditions such as heart arrythmias, stroke, epilepsy, breast and other cancers. The in depth structural and functional characterisation of this class of potassium channels is of great importance as they are interesting targets for new therapeutic developments. Advancement of knowledge in the structure and function of these channels will underpin drug targeting that will aid preventative healthcare, allowing Australians to age well and age productively.Read moreRead less

Parametric Brain Imaging via Modeling and Analysis of Electroencephalographic Signals. Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods.

This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data. The results will be used to probe spatiotemporal features of EEGs in normal subjects to explore the underlying fundamental mechanisms and to infer novel parameter variations of practical relevance.Read moreRead less
Electro-active and migratory peptides in lipid bilayers: NMR and biophysical studies. All living things are characterized by the separation of inner space from the surrounding medium by a self-assembling membrane. Selective entry and exit of water, ions and solutes is a defining feature of each type of cell. Some proteins sense the voltage difference across the cell membrane and open or close in response to voltage changes.

All living things are characterized by the separation of inner space from the surrounding medium by a self-assembling membrane. Selective entry and exit of water, ions and solutes is a defining feature of each type of cell. Some proteins sense the voltage difference across the cell membrane and open or close in response to voltage changes. Others, like bacterial toxins assemble in the membrane as pores, while other peptides migrate across the membrane piggy-backing their peptide cargo. The aim is to understand the molecular mechanisms in examples of these membrane-active peptides and proteins with a view to enabling rational intervention into their operation in situ in normal and disease states.Read moreRead less

To do this we will refine and develop methods using amphiphilic mesophases and micelles and state-of-the-art NMR spectroscopy. Electrophysiological analysis of ion channels and interactions with toxins will relate NMR structures to function. The NMR methodologies we develop will have broad applicability to membrane proteins in general.
