Host–Guest CatalysisA water-soluble [Fe4L6] capsule catalyzes the hy-drolysis of the neurotoxic organophosphate di-chlorvos. J. R. Nitschke and co-workers show intheir Communication on page 7958 ff. that dichlor-vos is hydrolyzed in the capsule and the water solubleproducts released from it.
Surface Plasmon ResonancesIn their Communication on page 8079 ff., M. AFiller and L.-W. Chou report the synthesis ofsilicon nanowires containing multiple, axiallyregistered, doped regions, which are investigatedby infrared spectroscopy.
ElectrocatalysisIn their Communication on page 8050 ff. Y.Yamauchi et al. report self-supported platinumnanorods that are prepared by electrochemicalassembly of platinum-containing micelles in thepores of a polycarbonate membrane.

… with controllable structures and flexible internal surfaces have been fabricatedfrom controllably evolved water/oil/water emulsions, as described by L.-Y. Chuet al. in their Communication on page 8084 ff. These microparticles could be used asmicrocontainers for controlled capture/release and as microreactors for confinedreactions.

Multimodal plasmonic resonances : Sili-con nanowires that contain multiple,dimensionally controlled, axially regis-tered doped regions were synthesized andinvestigated by angle-dependent mid-infrared spectroscopy (see picture; P =
partial pressure). The wires support mid-infrared multimodal localized surfaceplasmon resonances.
Hole in one! Hole–shell microparticles(blue, see picture) with controllablestructures and flexible internal surfaceshave been fabricated from W/O/W emul-sions. These microparticles could be usedas microcontainers for the controlledcapture/release of molecules, micro-sphere classification/separation, confinedcell culture, or as microreactors for catal-ysis.
A lead-free ferroelectric : The occurrence offerroelectricity is demonstrated in a sili-cate-based compound (Bi2SiO5, see pic-ture), by direct observation of polarizationswitching. The mechanism of ferroelec-tricity in Bi2SiO5 has been studied byRaman scattering, transmission electronmicroscopy, X-ray powder diffraction, andfirst-principles calculations. The observedferroelectricity stems from twisting of theone-dimensional SiO4 tetrahedral chain.
Electronic tuning: Nitroxyl radical 1 isshown to be an efficient catalyst for theoxidation of secondary alcohols, andpromotes oxidation through an oxo-ammonium species which is highly reac-tive because of the adjacent electron-
withdrawing ester groups. Chemoselec-tive oxidation of benzylic alcohols in thepresence of aliphatic alcohols is observedand is proposed to proceed by a rate-determining hydride transfer.
