uEXAFS and uXANES

300x300μm XRF map of the sample annealed at 600°C. The regions depicted as L and H, contain low and high iron concentration, respectively

Fourier transforms of the μ-EXAFS spectra. The spectra depicted as L and H, correspond to vitreous and microcrystalline regions, respectively (with F. Pinakidou et al, University Thessalonica).
