50_17/2011Cover Picture: Synergy of Homogeneous and Heterogeneous Chemistry Probed by In Situ Spatially Resolved Measurements of Temperature and Composition (Angew. Chem. Int. Ed. 17/2011)

The combination ... ... of a novel in situ sampling technique and a detailed model analysis was used to elucidate the interplay between the heterogeneous and homogeneous pyrolytic routes to H2 and CO in the catalytic partial oxidation of C3H8 over rhodium, as described by A. Beretta et al. in their Communication on page 3943 ff. The grasshopper in the picture represents the homogeneous chemistry, which skips the Rh surface and produces hydrocarbons in the gas phase. The gecko stands for the heterogeneous chemistry, which sticks on the Rh surface and leads to synthesis gas. The authors thank F. Tosi for the picture.

The in situ synthesis of double- or triple-decker cerium porphyrinato complexes on an Ag(111) substrate is described by D. Ecija, W. Auwärter et al. in their Communication on page 3872 ff. STM manipulation can be used to induce a reversible rotation of the upper porphyrin in the complexes.
