Cooperative molecular dynamics in surface reactions
K. R. Harikumar, Lydie Leung, Iain R. McNab, John C. Polanyi, Haiping Lin & Werner A. Hofer
Published online: 15 November 2009 | doi:10.1038/nchem.440
A cooperative reaction is reported whereby the halogenation of one silicon atom on a surface is shown to induce, invariably, halogenation of a neighbouring silicon. This is a first step towards using surface-propagated cooperative reactions to create molecular-scale patterns on surfaces.

Dynamic hook-and-eye nanoparticle sponges
Rafal Klajn, Mark A. Olson, Paul J. Wesson, Lei Fang, Ali Coskun, Ali Trabolsi, Siowling Soh, J. Fraser Stoddart & Bartosz A. Grzybowski
Published online: 15 November 2009 | doi:10.1038/nchem.432
An organic polymer scaffold has now been developed that can capture and release functionalized inorganic nanoparticles by the threading and de-threading of pseudorotaxane linkages. The capture–release cycles are reversible and programmable both chemically and electrochemically. In mixtures of different nanoparticles, the scaffold can capture one type selectively — thus acting as a selective nanoparticle 'sponge'.

Identification of active Zr–WOx clusters on a ZrO2 support for solid acid catalysts
Wu Zhou, Elizabeth I. Ross-Medgaarden, William V. Knowles, Michael S. Wong, Israel E. Wachs & Christopher J. Kiely
Published online: 08 November 2009 | doi:10.1038/nchem.433
Small alkanes are typically isomerized on tungstated-alumina solid-acid catalysts, but the origin of the activity has been unclear. Now, high-resolution imaging has revealed subnanometre Zr-WOx clusters to be the active sites.

Type-zero copper proteins
Kyle M. Lancaster, Serena DeBeer George, Keiko Yokoyama, John H. Richards & Harry B. Gray
Published online: 01 November 2009 | doi:10.1038/nchem.412
Copper-containing proteins can be classified into types 1 and 2, depending on their functional or spectroscopic properties. Now, a protein that fits neither type has been built using a scaffold made from the protein Pseudomonas aeruginosa azurin.

Complete chiral symmetry breaking of an amino acid derivative directed by circularly polarized light
Wim L. Noorduin, Arno A. C. Bode, Maarten van der Meijden, Hugo Meekes, Albert F. van Etteger, Willem J. P. van Enckevort, Peter C. M. Christianen, Bernard Kaptein, Richard M. Kellogg, Theo Rasing & Elias Vlieg
Published online: 01 November 2009 | doi:10.1038/nchem.416
Complete chiral symmetry breaking of an amino acid derivative is achieved by circularly polarized light irradiation of a solution of the racemate in contact with racemic crystals, followed by abrasive grinding. The chirality of the amino acid derivative in the resultant crystals is fully determined by the rotation sense of the irradiation.

Anhydrous proton conduction at 150 °C in a crystalline metal–organic framework
Jeff A. Hurd, Ramanathan Vaidhyanathan, Venkataraman Thangadurai, Christopher I. Ratcliffe, Igor L. Moudrakovski & George K. H. Shimizu
Published online: 18 October 2009 | doi:10.1038/nchem.402
Materials built from metal centres and organic ligands have traditionally attracted attention for their channels' host–guest properties. Now, controlling the occupancy of the channels by guest molecules has resulted in a framework that conducts protons under anhydrous conditions and acts as a gas-tight membrane, offering a promising approach to fuel-cell electrolytes.

Until print versions of AOP papers are published, they should be cited in the style "Author(s) Nature Chemistry advance online publication, day month year (doi:10.1038/nchemXXXXX)". Once the print version (identical to the AOP) is published, it should be cited as follows: "Author(s) Nature Chemistry volume, page (year); advance online publication, (doi:10.1038/nchemXXXXX)".
