Fatigue in Lead-free Piezoceramics. This project aims are to achieve a fundamental understanding of the fatigue behaviour of lead-free piezoelectric ceramics which achieve high strain through phase transformations and then ascertain the effects of this behaviour on material degradation rates.

This project aims are to achieve a fundamental understanding of the fatigue behaviour of lead-free piezoelectric ceramics which achieve high strain through phase transformations and then ascertain the effects of this behaviour on material degradation rates. The expected outcomes will facilitate replacement of toxic lead in commodity electronics. The focus will be on new lead-free bismuth-alkali-based piezoelectric ceramic systems which demonstrate exciting potential as alternate materials to lead zirconate titanate (PZT) materials. Successful optimisation of the materials' design and knowledge of their degradation rates are expected to facilitate their commercialisation through a profound reduction in the environmental challenges associated with manufacture and disposal of devices.Read moreRead less
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

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
In-situ biofunctionalisation for additive manufacturing. Additive manufacturing that incorporates printing of live cells can create hierarchical, multi-component structures that mimic biology.

Additive manufacturing that incorporates printing of live cells can create hierarchical, multi-component structures that mimic biology. However, an ability to include spatially segregated biological cues is currently lacking. This project will develop plasma pen modules to selectively functionalise surfaces and interfaces, as they are being printed, with robustly immobilised hydrogels and biological signalling molecules to direct cell behaviour. The expected outcome is a green technology enabling the fabrication of structures that replicate the native environments of cells in the body to provide optimal efficacy in drug discovery and regenerative medicine, and significant benefits for the Australian biomedical sector.Read moreRead less
A new dimension of functionality for high surface-area-to volume materials. This project aims to develop processes that can successfully functionalise the inner surfaces of high surface area to volume structures with interconnected porosity.

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
