Fig. 6. Absorbed mechanical energy (i.e., inelastic) as a function of maximum applied pressure for individual UiO-66 nanocrystals in the flat piston compression experiments. Insets: (a) side view TEM of a single crystal of UIO-66 mounted on the silicon wedge holder before compression; (b) same crystal after compression to 2000 μN, and (c) top view, SEM of a compressed nanocrystal resembling a flattened pancake.
