摘      要：Exactly 70 years after Kirkendall’s revolutionary experiments established the vacancy diffusion mechanism and the resultant Kirkendall effect and Kirkendall pores[1],Sun et al.[2]advanced the understanding of the Kirkendall effect to near atomic level with the real-time tracking three-dimensional(3D)evolution of colloidal nanoparticles under real reaction conditions.Smigelskas and Kirkendall[1]in 1947 reported an experiment on the interdiffusion between copper and zinc in a
