Inside Cover: Switching the Chirality of Single Adsorbate Complexes (Angew. Chem. Int. Ed. 22/2009)

Wrong handedness? No problem! K.‐H. Ernst et al. describe in their Communication on page 4065 ff. how the chirality of single adsorbates can be switched into the opposite enantiomeric state. By using inelastically tunneling electrons from the tip of a scanning tunneling microscope in an ultra‐high vacuum, certain molecular vibrations are excited that, in turn, cause different actions such as hopping, rotation, and chirality conversion at the surface.

     

Cover Picture: Nanoscale Chemical Imaging of the Reduction Behavior of a Single Catalyst Particle (Angew. Chem. Int. Ed. 20/2009)

Iron‐based catalysts for the Fischer–Tropsch synthesis bring about the conversion of synthesis gas (CO/H₂) derived from coal or biomass into liquid transportation fuels. In their Communication on page 3632 ff., B. M. Weckhuysen, F. M. F. de Groot, and co‐workers provide insights into the difference in behavior of the catalyst precursors during pretreatment in H₂ on both the nanoscopic and the bulk scale. These findings enable further understanding of how the activated catalyst works.
