Figure 4

Operando surface X-ray diffraction of the five samples performed during cyclic voltammetry in 0.1 M NaOH, showing from top to bottom the change in in-plane grain size, the change in out-of-plane grain size, the change in in-plane strain, and the change in out-of-plane strain. Potentials were IR-corrected. As a reference point for the strain and grain size changes, E = 1.00 V was chosen.
