• 5. Figure 14: (A) Distribution of carbonyl (red) compared to the distribution of other compounds (cyan) in a 65 × 50 µm area of the sample. This area was measured in 0.1 µm steps. A layer of skin, identified by the yellow rectangle and predominantly composed of carbonyl, can be seen diagonally at the top-left corner of the image. The white arrow points towards the top of the skin. The red box represents the area detailed in (B). (B) Carbonyl (288.5 eV) map of the area within the red rectangle depicted in (A). The map covers an area of 20 × 20 µm of the sample in steps of 0.1 µm. The scale bar is 2 µm. Dark areas correspond to the presence of carbonyl (the data were collected with the detector in X-ray absorption mode). The yellow rectangle highlights a carbonyl layer which seems to be organized in smaller substructures, with three of them delineated by the white circles. (C) Elemental mapping of carbon (red), calcium (blue) and iron (green) of one of the substructures indicated by the white arrow in (B). [O] . -1
