52_16/2013Cover Picture: De Novo Design of Nanostructured Iron–Cobalt Fischer–Tropsch Catalysts (Angew. Chem. Int. Ed. 16/2013)

A recording industry patent from the 1960s forms the inspiration for designing new core–shell Fischer–Tropsch catalysts. By tweaking the deposition and layer-growth process, G. Rothenberg et al. show in their Communication on page 4397 ff. how uniform spherical particles of iron oxide coated with a 1 nm cobalt shell can be prepared. Pelleted together with nanosized alumina particles, these catalysts are stable up to 673 K, and give good diesel fractions under Fischer–Tropsch conditions.

Epigenetic Modificationsfor001

5-Hydroxymethylcytosine (5hmC) is a recently discovered epigenetic modification that may be important in stem cell differentiation. In their Communication on page 4350 ff., H. Bayley et al. describe a method of detecting 5hmC in single molecules of DNA.


CO2 Capture

The open metal sites in metal–organic frameworks interact strongly with CO2, and this has been studied primarily in terms of adsorption properties. In their Communication on page 4410 ff., L.-C. Lin et al. now describe the dynamics of CO2 absorption.for002

Zintl Anionsfor003

In their Communication on page 4483 ff., R. M. Gschwind, N. Korber et al. present NMR spectroscopic evidence for Sn44− and Si44− in liquid ammonia. The existence of these tetrahedral cages of tin and silicon is thus not limited to solid-state compounds with electropositive metals.
