Type II solar radio bursts are associated with solar flares, coronal mass ejections (CMEs), and space weather events at Earth. They are the archetype of collective radio emission associated with shocks. This project aims to: answer longstanding fundamental scientific questions about type IIs using the new Murchison Widefield Array (MWA) and NASA spacecraft, while developing a new Australian capability in solar radio physics; perform new observations and theoretical calculations of relevant emission mechanisms, and, develop a new integrated data-tested theory and simulation capability for type II bursts that explains the emissions quantitatively, and positions us to predict the arrival of CMEs and related space weather at Earth.

Biomaterials with multifaceted tunability and bio-specificity. Polyurethanes, a family of polymers with independently tunable mechanical and biodegradation properties, will be developed as a versatile platform material for biomedical implants. Novel energetic ion treatments that allow the coupling of bioactive agents to surfaces will eliminate adverse reactions and enable integration with surrounding tissue.
New generation pulsed magnetron sputtering for the synthesis of advanced materials. Magnetron sputtering underpins the manufacture of many products ranging from semiconductor microelectronics to energy efficient windows. This project will create a new generation sputtering process fully compatible with current technology but capable of synthesising new phases and new film microstructures with greatly enhanced performance.
Integrated data-tested theory and modelling of type three solar radio emissions. Type three solar radio emissions, the Sun's most powerful and common, are the archetypal collective radio phenomenon in space physics and astrophysics. The project will integrate new theoretical work and simulations into a first integrated data-tested theory that can explain type three bursts, resolve long standing issues, and constrain solar physics.
Towards a steady-state fusion reactor: understanding and controlling eruptive instabilities in tokamaks. The lifetime of future fusion reactors may be severely compromised by periodic releases of internal energy which can damage the reactor walls. In an international research effort that is based on unique Australian optical technologies, the project aims to resolve some of the key issues that should allow these instabilities to be suppressed.
Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it c ....Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it can resolve the long-standing ‘number problem’. It also plans to apply the model to pulsars, and show how the long-standing dichotomy between the vacuum-dipole and rotating-magnetosphere models can be resolved by synthesising them. The project intends to combine these ideas into a new model for the most extreme examples of magnetic explosions: superflares and giant bursts on magnetars.Read moreRead less
Magnetic skeletons, solar flares, and space weather. This project aims to investigate how magnetic reconnection occurs during solar flares through accurate reconstruction of coronal magnetic fields from solar data before and after flares, and by reliable determination of field skeletons. Solar flares are dynamic events in the Sun's corona which cause local space weather storms. Magnetic reconnection is the accepted mechanism for flares but conventional models neglect the three-dimensional (3D) n ....Magnetic skeletons, solar flares, and space weather. This project aims to investigate how magnetic reconnection occurs during solar flares through accurate reconstruction of coronal magnetic fields from solar data before and after flares, and by reliable determination of field skeletons. Solar flares are dynamic events in the Sun's corona which cause local space weather storms. Magnetic reconnection is the accepted mechanism for flares but conventional models neglect the three-dimensional (3D) nature of the process. The project will improve 3D reconnection models for flares, and advance the ability to predict large events and hence space weather storms.Read moreRead less

The project aims to develop novel plasma-enabled processes for low-cost, energy-efficient, and scalable growth of high-quality graphene films for applications in touch screen, solar cell and other devices. It aims to discover non-equilibrium plasma-surface interactions enabling nucleation and growth of graphene films with large and low-defect domains on metal catalysts at low temperatures, and then develop energy-efficient, environment-friendly, and scalable fabrication and device transfer processes. These processes are designed to retain high quality of graphene films upon scale-up and will be compatible with the existing and emerging applications in touch screens and other devices. The expected outcomes include fundamental understanding and novel practical approaches to control synthesis and device integration of two-dimensional atomically-thin materials.Read moreRead less
The converging shock driven Richtmyer-Meshkov instability in magnetohydrodynamics. Fluid dynamic instabilities limit the chance of inertial confinement fusion, a carbon-free process, achieving net energy production. The project will investigate the effectiveness and consequences of suppressing one of these instabilities with a magnetic field.
