Other Supplementary Material for this manuscript includes the following:S

  • movie S1 (.mp4 format). Bending test of mesocrystals obtained from pH increase to pH 12.8 under the scanning electron microscope.
  • movie S2 (.mp4 format). Bending test of the same mesocrystals such as in movie S1 except that the applied stress is parallel to the crystal layer planes.
