These videos are part of a workshop I put on at the University of Delaware in August 2016. They discuss background information on EXAFS and a starting protocol to do shell fitting of EXAFS data.

If you would like to download copies of the PowerPoint presentations of these videos, click below on the links:

1.) PowerPoint file for first presentation
2.) Powerpoint file for second presentation

If you would like to follow along with the fitting and practice for yourself, click below on the links:
The citations for where the actual data were published are also linked to the papers.

1.) nickel foil (Citation: Siebecker et al., 2014)
2.) beta-nickel hydroxide (citation: Scheinost and Sparks, 2000)
3.) nickel reacted with pyrophyllite for six years (Citation: Livi et al., 2009; Supplementary Materials)

If you have any questions about the data or videos, please feel free to contact me.
