The cover picture shows the formation process of brookite‐type TiO 2 hollow spheres through layer‐by‐layer assembly and hydrothermal treatment. The core–shell particles were formed by alternate deposition of the titanium–glycolate complex and positively charged polyelectrolyte on spherical polystyrene spheres utilizing electrostatic interactions. Hollow spheres formed with the polyionic titanium–glycolate complex and the cationic polyelectrolyte were obtained by removal of the polystyrene templates. The hollow shell was successfully crystallized as brookite‐type TiO 2 by a hydrothermal treatment at pH = 4. Details are discussed in the article by K. Katagiri et al. on p. 3267 ff.
