From: Inflating hollow nanocrystals through a repeated Kirkendall cavitation process
Transformation of solid Pd nanocubes into Pd hollow nanocrystals with hollow interiors. a–c TEM images of Pd nanocubes, Pd-P intermediates, and hollow Pd nanospheres, respectively. Scale bars in a–c are 5 nm. d Snapshots of a Pd nanocrystal at different simulation time. e Instantaneous diffusion coefficients D of Pd and P atoms during the simulation. f TEM images of hollow Pd nanospheres at a low magnification. Scale bar in f is 20 nm
