Prof. John Tse [University of Saskatchewan, Canada]


Title: Experimental high pressure research and theoretical studies on the reactions of CO2 with SiO2

Time: 10:00 - 11:00,  December 5

Place: Auditorium Room 410, Building 6, HPSTAR (Shanghai)

Host: Bin Chen


Abstract:

In this presentation,prof.John S. Tsewill report on experimental development of two synchrotron based techniques (i) Fe M-edge inelastic scattering for the characterization of the high spin -> low spin transition and the associate change in the crystal field in FeS and (ii) the use of infrared reflectivity in the determination of transport properties. Then I will present results on recent theoretical studies on the phase diagram of solid and molten CO2 and the reactions of CO2 with SiO2 at high temperature and high pressure, particularly, on the formation of the crystalline cristoablite structure.


Biography of the Speaker:

John S. Tse started his research career in synchrotron radiation in 1975 as a graduate student at the University of Western Ontario.  After receiving his Ph.D. in 1980, he moved to the National Research Council of Canada in Ottawa as an NSERC Fellow. He was appointed scientific officer in 1981. In 1990, he moved to the newly created NRC Steacie Institute for Molecular Science and evidently achieved the highest and prestigious rank of principal research officer in 2000. He was the leader of the Theory and Computation Program from 1995 to 2004. In 2004, he joined the University of Saskatchewan the Department of Physics and Engineering Physics. He was appointed as the first Baoyugan Professor at Laboratory for New Nanostructured Materials, Zhejiang University from 2008-2010. Currently he is a professor at the State Laboratory of Superhard Materials, Jilin University in 2013.

Dr. Tse has a very broad research interest at the converging frontiers of chemistry and physics.  While an undergraduate student, he published his first scientific paper in 1975 on the structure of Dacron. In his early career, he made several notable contributions to natural gas hydrates. For this work, he was awarded the 1995 Chemical Society of Canada Noranda award for a physical chemist under the age of 45. He was involved in high pressure science since 1997. He was inducted as a Fellow into the Royal Society of Canada in 2008.  He received an earned D.Sc from University of Saskatchewan in 2012.

Dr. Tse is an active member of the synchrotron community. He chaired the Review Oversight Committee during the construction of the Canadian Light Source. Later, he led the development of the high pressure diffraction facility. He had serve on many national and international committees on neutron and synchrotron facilities.
