Fig. 5

A Corresponding HRTEM and SAED images, collected from zone i-iv in Fig. S8, showing differences in mineral assemblies and their crystallinities of mineral particles at the FE and TE samples. B EELS spectra, acquired at the phosphorus L2,3 edge, carbon K edge, calcium L2,3 edge, nitrogen K edge and oxygen K edge, showing differences in the nanoscale chemical environment of mineral particles (i-iv) in (C). C HHADF-STEM images and corresponding composition maps, collected at the calcium L2,3 edge, nitrogen K edge and oxygen K edge, illustrating the spatial distribution of these elements within the mineral particles from different zones (i-iv) in Fig. S8. (red: nitrogen K edge, green: oxygen K edge, blue: calcium L2,3; The original images and processing details are provided in Fig. S14). Scale bar in (A, HRTEM images): 10 nm; (A, SAED): 5 1 /nm; (C): 10 nm. Abbreviations, FE, ACL-femoral enthesis; TE, ACL-tibial enthesis. Source data are provided as a Source Data file.
