k2-weighted EXAFS spectra (left) and their corresponding Fourier transform magnitude (right) collected at different edges covering the full energy range of the beamline. Samples are from different research projects conducted at the XAFS/XRF beamline: Ag K-edge (25.514 keV) in AgCu alloys as electro-catalyst for oxygen reduction reaction; Mo K-edge (20.000 keV) in Fe1.7Mo0.15O3 for nonstoichiometric systems for ionic conductivity behaviour; Y K-edge (17.038 keV) in Fe1.94Y0.06O3 for nonstoichiometric systems for ionic conductivity behaviour; Pb LIII-edge (13.035 keV) in ancient human bone (3000 BC); Cu K-edge (8.979 keV) in ancient human bone (3000 BC); Ti K-edge (4.966 keV) in R-TiO2–x samples for visible-light-driven photocatalysis. |
