Chang, G. F,rey et al. in their Communication on page 4144 ff. After dehydration of MIL101, grafting with amine molecules followed by noble-metal encapsulation leads to metal–organic frameworks having high catalytic activity in the Knoevenagel condensation and the Heck coupling reaction. Amyloid Structures In the Minireview on page 4062 ff., E. Gazit and I. Cherny describe the substance classes of amyloids, which are often involved in serious diseases. However, these protein structures have beneficial properties for nanotechnological applications. Organic Field-Effect Transistors Solution-processable organic semiconductor materials enable the economical construction of flexible electronic components. U. Scherf and co-workers present strategies for the solubilization and preparation of organic semiconductors in their Review on page 4070 ff. Nanoporous Materials The breathing (expansion and contraction) of metal–organic frameworks in the presence of various liquids has been studied by F. Millange, R. I. Walton, and coworkers, as reported in their Communication on page 4100 ff. Time-resolved diffraction studies reveal the rapid exchange of guest molecules.
