题目: Canadian Light Source: an Introduction and its Application to Energy Materials
The Canadian Light Source (CLS) is Canada's national centre for synchrotron research. It is built as a state-of-art facility that is advancing Canadian science and industry. Launched in 1999 and officially opened in 2004, it is successfully operating 14 beamlines, covering the range from the far-IR to hard X-rays. In this presentation, an overview of the operational beamlines will be given. The future of the CLS, such as Phase III and IV projects will also be discussed.
In the second part of the talk, examples will be shown to compare different techniques such as photoelectron, photoabsorption and scanning transmission X-ray microscopy, on the applications of energy and nanomaterials.
Thomas Ellis received B.Sc. in Engineering Physics from Dalhousie University in 1978, and Ph.D in Physical Chemistry from University of Waterloo in 1984. After postdoctoral appointments at AT&T Bell Labs, Murray Hill, NJ, he went to Universite de Montreal, as a Professor of Chemistry in 1986. Afterwards, he went to Acadia University as the Dean of Research and Graduate Studies in 2002. Since 2005, he has been the director of Research at the Canadian Light Source. Dr. Ellis's research background involves of Molecular beam scattering from surfaces, rare gas monolayers on graphite, tine-resolved electron energy loss spectroscopy (HREELS), adsorption and reactions of small molecules on metal surfaces, the interaction of water with surfaces, FTIR and Raman spectroscopy of surfaces, self-assembled monolayers and self-assembled materials, biological surfaces, adhesion of dental materials to dentin surfaces. Currently, his research focuses on synchrotron IR spectroscopy of single cells. In CLS, he is the Chair of Beamline Advisory Committee, Secretary of Scientific Advisory Committee, Chair of Allocation Committee, Observer of CLS Board of Directors, and is responsible for the Peer Review Committee.
Yongfeng Hu received B.Sc. in Chemistry from Shandong University in 1988, and Ph.D in Chemistry from University of Western Ontario in 1996. After postdoctoral appointments at the University of Western Ontario and Princeton University, he went to University of Wisconsin-Madison, as a beamline manager at the Canadian Synchrotron Radiation Facility in 1999. Since 2003, he has been at the Canadian Light Source as a staff scientist. Dr. Hu's area of expertise is synchrotron radiation instrumentation and applications. He has built and commissioned three beamlines (soft and hard X-rays) at synchrotron facilities in US and Canada; designed and built many endstations (photoelectron and photoabsorption) for applications of synchrotron based technique. Currently, he is pushing for 搑eal? in-situ measurements of environmental and catalytic samples at the CLS. He is the author or co-author of around 100 peer-reviewed papers published in areas of atomic and molecular chemistry and physics, material and environmental science, and synchrotron instrumentation.
