Abstract Crystal gazing : A simple Pd‐catalyzed site‐specific nanoetching method was developed to visualize the polycrystalline nature of Fe 3 O 4 (see picture), Fe 2 O 3 , MnFe 2 O 4 , CoFe 2 O 4 , and MnO nanoparticle systems. The technique relies on the very fast etching speed of the grain interface within bi‐ or polycrystalline nanocrystals.
