Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 3. (A) STEM image and corresponding EELS signals for C and O at various parts, (B–F) Fe K-edge, Co K-edge, Ni K-edge, Cu K-edge, and Pt L3-edge XAS spectra and corresponding derivative curves for HEAN/CNT. (G) The formation energy of 250 structures is considered with a stochastic mixing method. (H) Bader charge analysis and (I) the D-band projected DOS (PDOS) of different elements in HEANs.
