Inside Cover: Nanoscale Reactor Engineering: Hydrothermal Synthesis of Uniform Zeolite Particles in Massively Parallel Reaction Chambers (Angew. Chem. Int. Ed. 47/2008)
Geodes are hollow, globular rocks with crystals lining their internal surface. The production of such structures in the submicrometer regime is described by A. Stein et al. in the Communication on page 9096 ff. Silicalite-1 crystallizes in a geode-like manner within the confinements of porous carbon reactors with an inverse opal structure. The zeolite morphology can be engineered by adjusting the shape and size of the reactor pores, interfacial interactions, transport phenomena, and precursor conditions.
