报告题目：Case studies in structural and microscopic analysis: some misunderstanding and mistakes in XRD, EDP and image
内容简介：Solid-state material is a strong correlation system, where the structural and chemical arrangement at different length scales are very complicated. It is very often found that the use of these techniques and associated analysis are abused in the literature. In this talk, I will use several samples to demonstrate the such kind of cases and guide you to use these techniques correctly and precisely in your research in the field of materials science and engineering.
Yun Liu graduated from the Xian Jiaotong University, China with her BSc, MSc and PhD. She has since held a position at the National Institute of Advanced Industrial Science and Technology (AIST), Kyushu, Japan (1998-2001) before the commencement of her Postdoctoral Fellow position at the Research School of Chemistry in 2001. She was awarded fellowships of the AIST (1998-1999), the Science and Technology Agency (1999-2001, now renamed as the Fellow of Japan Society for the Promotion of Science) and the Australian Research Council (ARC) Queen Elisabeth II (2006-2010). She was made a fellow of the Australian Institute of Physics (FAIP) and Certified Materials professional (CMP). She was also a member of the Materials of Australia (MMA) and the Society of Crystallographers in Australia and New Zealand (MSCANZ). She was promoted to Associate Professor at the Research School of Chemistry in 2011.
Functional materials can convert one form of energy to another and thereby achieve an intelligent action as sensors or actuators, which are recognised as a vital area for the growth of the nation's economy. Our work is mainly concentrated on the interaction amongst synthesis, microstructure and polarisation-related properties of functional materials. Applied areas of interest are in sensors, transducers, actuators, microwave components used in telecommunication and information technology, and smart devices for renewable energy. On the fundamental side, we develop multidisciplinary expertise in wet chemical synthesis, crystal chemistry, defect chemistry, physical property characterisation, and modelling of functional materials. The group has a very close collaboration with Prof. Ray Withers.
