a MgO nanocube compression modeled using MD. A perfect \(\frac{1}{2}\langle 110\rangle\){110} dislocation nucleates from a top corner (blue line), just below the indenter. The red arrow refers to the Burgers vector direction. b Surface dislocation nucleation in a MgO nanocube observed during in situ TEM nanocompression test at room temperature (courtesy of Pr. Masenelli-Varlot). c \(\frac{1}{2}\langle 110\rangle\){110} slip systems in MgO.
