Cover Picture: Microcontainers with Fluorescent Anisotropic Zeolite L Cores and Isotropic Silica Shells (Angew. Chem. Int. Ed. 7/2009)
Nanocontainers composed of zeolite L crystals were filled with fluorescent dyes and used as the core of a silica “box-in-a-box” construction as in Russian matryoshka dolls, as described by A. Guerrero-Martínez, L. de Cola, and co-workers in their Communication on page 1266 ff. The anisotropic cores and isotropic shells of the multicolor emitting systems are separated by a polyelectrolyte layer and can be addressed independently. This approach opens fascinating routes for the construction of multifunctional nanosystems.

Multiwall WS2 nanotube templates were used as hosts to prepare core–shell PbI2@WS2 inorganic nanotubes by a capillary-wetting method, as described by R. Tenne and co-workers in their Communication on page 1230 ff.
Natural Product Synthesis
In their Communication on page 1283 ff., B. B. Snider et al. report the stereospecific condensation of a fully functionalized ketal aldehyde and a 2,6-dihydroxybenzoic acid as the key step in the synthesis of (−)-berkelic acid.
