Analyses on CN material. Images acquired by (a) optical microscope showing a large and thin flake (zoom on an isolated flake in inset) and hollow spheres (yellow arrows), (b) optical microscopy analysis of a flake using polarized light. The brightness of the flake changes with the relative angle between the polarizer and the sample (zoom in inserts, white arrows as a guide to the eye), evidencing its crystallinity). The flake shows different domains due to folds, see S1-3, (c) SEM, the zoom in inset shows a rolled up flake. (d) EDS analysis on CN sample.
