Extended Data Fig. 3: High-angle-annular-dark-field (HAADF) image.
From: Multi-heteroatom-doped carbon from waste-yeast biomass for sustained water splitting
High-angle-annular-dark-field (HAADF) image of R-2 and the corresponding energy-dispersive X-ray spectroscopy (EDS) elemental mapping images show that the sample contains C, Ru, S, N and P. Scale bars in 1 µm.
