Engineering interfaces to enable a new generation of hybrid materials. Hybrid combinations of hydrogel and solid materials allow a high level of functionality for devices such as tissue-engineering scaffolds and soft machines. However, the weak bonding between hydrogels and solids severely hampers their function.

Advanced materials for space propulsion: satellites and cubesats. Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life. Through modelling and experiment, this project will show how intelligent selection of advanced materials and plasma parameters can minimise surface wear, enable in sit ....Advanced materials for space propulsion: satellites and cubesats. Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life. Through modelling and experiment, this project will show how intelligent selection of advanced materials and plasma parameters can minimise surface wear, enable in situ material repair to extend device lifetime, and modulate plasma properties to increase thruster efficiency for a given task. These benefits enable reliable propulsion platforms for massive communication and observation satellite networks and deep space exploration.Read moreRead less

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.

This project aims to develop processes that can successfully functionalise the inner surfaces of high surface area to volume structures with interconnected porosity. These structures underpin many processes in modern manufacturing. Examples include columns and fluidised beds for purification, materials for energy storage and conversion, biomedical scaffolds and structures for high sensitivity sensing. The efficacy of these materials is strongly affected by the condition of the surfaces, but modifying the surfaces of internal pores deep within such structures presents major challenges. This project will provide environmental friendly, dry plasma processes to tailor surface functionality, improving the efficacy of existing processes and opening up new far reaching applications for such materials.Read moreRead less
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.
