Summary
The general Richtmyer-Meshkov instability in magnetohydrodynamics. Fluid dynamic instabilities limit the chance of inertial confinement fusion, a carbon-free process, achieving net energy production. In highly idealised circumstances it has been shown that one of these instabilities can be suppressed by a magnetic field, a phenomenon that this project will investigate in the general case.
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.
A novel air-cooled fuel cell system. This project presents a novel cooling technology for fuel cell systems. This new design will not only save up to 50 per cent of the material cost but also leads to 20 per cent less fuel consumption compared to the existing fuel cells. This can save us billions of dollars per year with profound impact on our nation's carbon-emission-free alternative energy sources.

Specifically, the project plans to provide new insight into the interaction between ionised gas plasma jets and biological soft tissue. It plans to use advanced analytical techniques and modelling simulations to investigate the physics of the plasma jet and processes occurring at the jet–tissue interface. It also plans to use (bio)engineered tissue targets, chemical, biological and cellular assays to probe the transport and effects of plasma reactive species deep within tissue. This new knowledge would enable the development of new plasma sources and protocols for applications in health, medicine, biotechnology and manufacturing.Read moreRead less
Nanophotonic tandem designs for high efficiency solar cells. This project will develop high-efficiency tandem solar cells that combine established silicon cell technology with novel low-cost thin-film solar cells. It will incorporate nanostructured layers between the cells that selectively trap different wavelengths of light, maximising light absorption in the top cell. This will make it possible to use a very thin top cell, reducing the requirements on electronic quality of the material. This p ....Nanophotonic tandem designs for high efficiency solar cells.

It will incorporate nanostructured layers between the cells that selectively trap different wavelengths of light, maximising light absorption in the top cell. This will make it possible to use a very thin top cell, reducing the requirements on electronic quality of the material. This project will also develop self-assembly techniques to enable the new nanostructures to be fabricated quickly and cheaply but with a high degree of control. Such cells will allow open the door to higher efficiencies, and lower costs, than is achievable with conventional solar cells.Read moreRead less

Cadmium telluride/Germanium (CdTe/Ge) tandem-junction solar cells for efficiency enhancement in thin-film photovoltaics. The purpose of this project is to improve the efficiency of large-area, thin-film CdTe solar cells by using them in a tandem arrangement with thin-film Ge cells. An increase of 25 per cent in efficiency appears possible, which would greatly improve the prospects for cost-competitive photovoltaic power generation.
