From: Inflating hollow nanocrystals through a repeated Kirkendall cavitation process
Size variation of the hollow nanocrystals obtained after repeated Kirkendall cavitation processes. TEM images and statistical analyses of particle size and pore size distribution for a, d H-Pd-1, b, e H-Pd-2, and c, f H-Pd-3. Scale bars in a–c are 50 nm
