49_38/2010Cover Picture: Supersensitive Detection of Explosives by Silicon Nanowire Arrays (Angew. Chem. Int. Ed. 38/2010)

TNT and other explosives can be detected in air by using silicon nanowire arrays modified with electron-rich aminosilane monolayers. As F. Patolsky and co-workers report in their Communication on page 6830 ff., these devices, in which the electron-deficient explosive molecules are bound to the monolayer through charge-transfer interactions, offer rapid label-free detection of explosives down to a detection limit of 0.1 femtomolar (1×10−6 ppt).

Cavitand Gelatorsfor001

In their Minireview on p. 6718 ff, J. W. Steed and J. A. Foster describe how the broad principle of supramolecular chemistry and an understanding of gel structure can be utilized intelligently in the design of responsive cavity-containing gelators.


Carbon Quantum Dotsfor002

Just like the fullerenes, carbon nanotubes, and graphenes, the latest form of nanocarbon, the carbon nanodot, is inspiring intensive research efforts. The current status of this field is summarized by S. N. Baker and G. A. Baker in their Review on page 6726 ff.


Bimetallic Catalystsfor003

A catalyst containing two salen/Ti=O units allows the enantioselective cyanation of aldehydes. In their Communication on page 6746 ff., K. Ding and co-workers demonstrate the utility of this catalyst to afford enantioenriched natural or nonnatural cyanohydrin derivatives.
