Num: number; An: analyses; SEM-EDS: Scanning electron microscopy coupled with energy dispersive X-ray spectroscopy; μ-RS: micro-Raman spectroscopy; XRD: X-ray diffraction. The objects' identification number is the same as presented in Figs 4–11, Tables 2–5, S1 and S2 Figs, S1 Table, S1 Text.
* Samples AT1–AT19, AT22 refer to residues stuck on carbon adhesive tabs, and samples T1, T3, T5–T10, T12, T17, T18 refer to loose residues kept in sample tubes.
