Re: [Ifeffit] Differences between fluorescence and transmission of the same sample

We already tried with other catalyst like RuSe and CoSe. What was more exiting for me was the similarity between the data for anode pellet, cathode removed, and fluo data(attachment). Actually we want to generate exact conditions in a Direct Methanol fuel cell (methanol crossover and starvation), so we still like to keep both pt system there. Thank you once again, Ditty On Fri, May 14, 2010 at 3:09 PM, wrote:

Dear Mohamed,

There is an example of CeO2 EXAFS analysis, taking into account background problems, in the following paper: *J. Pade?nik Gomil?ek, I. Kozjek-?kofic, N. Bukovec, A. Kodre */X-ray absorption study of CeO2 and Ce/V mixed oxide thin films obtained by sol-gel deposition. /* *Thin solid films, vol. 446, issue 1, (2004) 117-123. regards Iztok Arcon

Dear all I am trying to use artemis to do fitting to CeO2. But really I cant get the right way to do that. During the fitting, I am using amp as set and change in N degeneracy of the path. attached is the best fit i got but it still not good and the chi-square is 41.109065479 so can you suggest me what to do

thanks

Mohamed
