Terminplanung kommende Semester und Vortragsarchiv BayCEER Kolloquium
As one of the most extensively applied synchrotron techniques, X-ray absorption fine structure (XAFS) spectroscopy plays a unique role in many scientific areas. Its element specific local structure probing capabilities make molecular level understanding for both crystalline and amorphous systems possible.
This presentation will first present X-Ray Absorption Spectroscopy (XAS) facilities and capabilities specific to the Hard X-ray MicroAnalysis (HXMA) beamline at the Canadian Light Source. HXMA is a wiggler-sourced hard X-ray beamline with an energy coverage of 5–40 keV, which is currently the only hard X-ray extended X-ray absorption fine structure (EXAFS) beamline available for Canadian Light Source users.
The presentation will further focus on the principles of XAS as well as its applications. Two X-ray absorption near edge structure (XANES) theoretical molding guided case studies which will be specifically discussed are (1) the speciation of chromite in a biochar system, and the corresponding size estimation for the sub-nano scale chromite particle of the system, and (2) speciation of vanadyl porphyrins in the oil sands fluid petroleum coke from Alberta, Canada, respectively.
