Hi Dr. Bunker; Let me at first thank you very much for the corrections and edition that you have made on the dissertation. I just want to remind you those sections that need more corrections. First the Introduction section which is very disperse! As we have "Abstract" part and any chapter has introduction we may eliminate the introduction chapter and add its stuff to other introduction parts or if you think it is better to keep it, I really appreciate if you write it in the way that more emphasize will be on last part . The next part is section 2.6, "X-ray Fluorescence Spectroscopy" which I want to talk about the differences and similarities between that method and XAFS. Regards, Firouzeh.
