Advanced EELS and camera technology for researches in physics, chemistry and life science
Presenter: Dr. Zibin Chen, Application Scientist of Scitek Australia Pty Ltd
Abstract: Transmission electron microscopy (TEM) is arguably the most powerful technique for the characterisation of materials structures at the micro-, nano-, and sub-nanometer scales. Electron Energy Loss Spectroscopy (EELS) is a TEM technique for composition and chemical environment or chemical bonding analysis. Image recording is critical for TEM study of materials. This presentation will focus on the newest development in the data acquisition and
analysis of EELS and in camera technology. The new EELS technique enables the chemical bonding and electronic structural analysis for both light and heavy elements with very high energy resolution. The new TEM camera with ultra-high speed and detective quantum efficiency allows imaging beam-sensitive biomaterials and chemical materials with extremely low electron beam dose, which provides an effective solution to minimise structural degradation of the biomaterials and chemical materials during the TEM study process. Combination of the state-of-art camera and EELS techniques offers an extremely powerful tool for the investigations of biomaterials and catalytic processes in nanoscale as well as the accurate quantitative elemental information.
Brief Bio: Dr. Zibin Chen conducted his postgraduate research in the University of Sydney under the supervision of Prof. Xiaozhou Liao and received his PhD degree in 2017. After his PhD, he worked in the University of Sydney as a postdoctoral research associate until December 2017 when he joined Scitek Australia Pty Ltd, which is a world leader in vacuum technology and surface science technology, as an application scientist.
Dr. Chen’s research focuses on the applications of advanced electron microscopy techniques on the investigations of the structures and structure–property relationships of advanced materials including semiconductors and ferroelectric materials. He has published high-quality papers in top journals including Nature Materials, Physical Review Letters, Physical Review Applied, and Acta Materialia. He was awarded a Chinese Government Award for Outstanding
Self-financed Students Abroad in 2017 for his PhD research.
