Planetary nebulae, the extended shrouds of dying stars, are a fascinating, brief period in the life of most stars. Our Sun will eventually go through this phase engulfing the earth. Planetary nebulae are unique celestial laboratories thanks to their rich emission line spectra. They are amongst the most beautiful and mysterious of objects, whose startling images act as a photogenic magnet for public interest. Behind their beauty hides the mystery of how stars return carbon, one of life's essential building blocks - to interstellar space. This project will constitute the next major breakthrough in understanding these processes and addresses several significant astrophysical problems in the field via unique Australian data and instrumentation.Read moreRead less

This project aims to develop new knowledge through a better understanding of physics interactions of particles in compounds with sub-micron size. Research on radiosensitisation by sub-micrometre sized nanoparticles (NPs) is hot worldwide because it could treat cancer, but the physical/physico-chemical/biological mechanism of radiosensitisation is unclear because no physical models describe particle interactions at nanometre scale in solid state nanometre sized objects. This project will develop and evaluate specialised physics models to describe particle interactions in NPs and help optimise nanoparticle technology. It will develop expertise in Australia in physics modelling for nanomedicine and other applications of nanotechnology exposed to radiation (e.g. telecommunications, aviation and space).Read moreRead less

Piezoelectric transducers provide the highest positioning accuracy of any known actuator and the highest dynamic force resolution of any known sensor. However, these capabilities are limited to macro scale applications since piezoelectric materials are not compatible with integrated circuit (IC) or Micro-Electro-Mechanical Systems fabrication processes. This project aims to extend the use of piezoelectric materials to the meso- and micro-scale by fabricating miniature piezoelectric positioning and sensor systems. These devices will include six-axis nano-positioners and ultra-high resolution accelerometers and gyroscopes.

Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties.
