Inside Cover: Multicompartmental Microcylinders (Angew. Chem. Int. Ed. 25/2009)

Multicompartmental microcylinders can be produced by a combination of electrohydrodynamic co‐spinning and microsectioning, as described by J. Lahann et al. in their Communication on page 4589 ff. The number of individual compartments, relative compartment orientation, chemical composition and functionality, and aspect ratio can be precisely tuned. Each color in the longitudinal and cross‐sectional micrograph images depicts an individual compartment.

     

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.
