The Waterloo Institute for Nanotechnology (WIN) presents a seminar by Dr Tsun-Kong (T.K.) Sham, Canada Research Chair in Materials and Synchrotron Radiation and Chemistry Professor at Western University, Canada.
Synchrotron Solutions for the Length Scale Science of Matter and Time
The advent of maturing synchrotron capabilities and nanotechnology has provided an exciting playground and unprecedented opportunities for materials research. Nanoscience deals with materials whose properties can be tailored with their size and morphology. In parallel to this development, the very bright, energy (wavelength)-tunable, highly collimated and pulsed synchrotron light sources of the third generation are making synchrotron light more powerful and readily available. In this talk, several recent applications of synchrotron techniques and their connection to length scale science will be presented. These include: X-ray Absorption Fine Structures (XAFS), X-ray Emission Spectroscopy (XES), X-ray Excited Optical Luminescence (XEOL) in both energy and time domain and Scanning Transmission X-ray Microscopy (STXM). Studies of nano-structures and nanocomposites interface, and nano-sphere ceramics for drug delivery, among others will be described to illustrate the unique solutions synchrotron technology can provide. The prospects of emerging techniques such as in situ/in operando tracking of energy devices, High Energy X-ray Photoelectron Spectroscopy, soft and tender X-ray microprobes, and confocal X-ray microscopy will also be noted.
Dr T.K. Sham
A world-class materials chemist, Tsun-Kong Sham is the authority when it comes to the application of synchrotron radiation to materials science. His area of research is also of strategic importance to Western University, anchoring its strength in materials for sustainable energy.
As a Tier I Canada Research Chair, a Fellow of the Royal Society of Canada and recipient of the prestigious John C. Polanyi Prize of the Canadian Society for Chemistry, Sham’s research productivity remains high, with more than 440 peer-reviewed papers and more than 8,000 citations – more than 600 citations last year alone – to his credit.
In addition to his distinguished record as a synchrotron researcher, Sham has been vital as part of the administration of the Canadian Light Source, as well as scientific director of the Canadian Synchrotron Radiation Facility at the Synchrotron Radiation Center (University of Wisconsin-Madison) since 1998.
