Figure 3
Comparison of the two component spectra obtained by modified non-negative matrix factorization (interfacial in blue and bulk in green) with reference spectra from Conradson et al. (2013

) (U₃O₇ in orange and UO₂ in red). Spectra are offset for clarity. The isosbestic points at 531.5, 535.3 and 536.9 eV as determined by k-means cluster analysis are shown as dotted lines.
