A/Prof Simon Ringer.
Brief summary of expertise and significant research achievements:
A core component in the design of new nanomaterials is the
characterisation of those materials at the nanometre and atomic
scales by means of high-resolution microscopy and microanalysis
techniques. A/Prof. Ringer has made significant contributions
to this area, by combining a variety of advanced techniques in:
1. microscopy, including conventional and high-resolution scanning and transmission electron microscopy, and field ion microscopy;
2. diffraction, including selected area, microbeam and convergent beam electron diffraction, and powder X-ray diffraction (XRD); and
3. microanalysis, including energy dispersive X-ray spectroscopy (EDS), electron energy loss spectroscopy (EELS) and three-dimensional atom probe analysis.
His specialty is the use of these powerful tools to explore processing-structure and structure-property relationships in materials and to reveal the process of microstructure development. Frequently, this has required identification of new or little-known phases in multicomponent systems. A/Prof. Ringer has made significant impact on more challenging problems associated with segregation and atomic clustering and their relation to microstructural phase decomposition, transformation and the evolution of nanostructure.
Current research work includes:
* Advanced characterisation of nanomaterials;
* Atom probe informatics;
* Nanostructural design of light alloys; and
* Synthesis and characterisation of polymer nanocomposites.
