Figure 10. (A) Sequential in-situ HRTEM images during the tensile deformation process of an Ag nanowire. Reproduced with permission^[52]. Copyright 2019, ACS publications. (B) Left: Slip-activated surface diffusion occurring with the formation of stacking faults in nanoporous gold. Right: Schematic illustration of the thinning process of gold nanowire, which is through the slip and slip-activated surface diffusion. Reproduced with permission^[48]. Copyright 2019, Elsevier.
