Figure 2
(a) Optical microscopy images of the inner surface of a 110 µm thick eggshell section showing the membrane on the left and mammillary spherulitic layer on the right; (b) X-ray transmission image of the region indicated by the box in (a) obtained using a 1 µm diameter beam with a scan step of 2 µm horizontally and 5 µm vertically; (c) integrated SAXS intensity (arbitrary units) of the same region; (d) details for the central disc (box in c); (e, f) individual SAXS patterns taken, respectively, at the border and the centre of the disc; (g) image of the T parameter (in nm) using the same scan parameters as in (b) and (c); (h) azimuthally averaged intensity profiles from the scattering patterns (e) and (f). The red dotted line shows a −4 slope in the double-logarithmic representation in accordance with Porod's law. |
