A controllable method for engineering the internal shape of silica nanoparticles is designed by Hyon Min Son, Jeffrey I. Zink, and Niveen M. Khashab on page 307. The authors calcinate hydrated iron salts in the pores of both spherical and rod‐shaped mesoporous silica. The internal structure can then be changed from an ordered 2D hexagonal structure into large hollow cores, a smaller number of large pores (of ca. 18 nm) or a large number of 10‐nm voids.
