From: 2D fracture-resistant high-entropy-oxide scaffold enabled multifunctional nanomembrane

High-resolution XPS spectra of (a) C 1 s, (b) O 1 s, (c) Co 2p, (d) Ni 2p, (e) Ti 2p, (f) Zr 3 d, (g) Hf 4f , and (h) the corresponding relative atomic percentage of metallic elements with different etching durations. i Nano-FTIR absorption mapping for C–O stretching bonds at a wavelength of 1107 cm-1, (j) point absorption spectra of the dual phases at the corresponding positions and (k) the variation of absorption intensity along the line scan in panel (i). l Schematic illustration for the dual-phase nanostructure. AM-FM mappings of the (m) contact stiffness and (n) loss tangent, and (o) their variations along the line scans in panels (m) and (n). Tk and Tδ denote the correlation lengths of stiffness and loss tangent, respectively. Source data are provided as a Source Data file.
