Seminar Title: 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.
