Surface patterning
Perspective by Braunschweig et al.The direct transfer of molecules onto surfaces to form specific patterns has had a significant impact in a number of areas of science and technology, ranging from biomedical diagnostics to nanoelectronics. This Perspective compares and contrasts different lithographic approaches to molecular printing and considers future directions for this field.
Cover story
Metal–organic frameworks
Article by Xiao et al.Materials formed by linking metal ions with organic ligands have potential for gas adsorption and storage, and can be flexible in response to stimuli. Now, suitable organic linkers result in a material that undergoes a large structural change, but does not lose crystallinity.
Current issue
A systematic variation of ligand properties allows an in-depth experimental and theoretical study of a highly non-canonical bonding situation in certain organic compounds, and provides insight into the criteria that must be fulfilled for such compounds to be truly considered as carbon(0)-containing entities.

Polymer synthesis
Review by Matyjaszewski & TsarevskyThe simplicity and broad applicabilty of atom transfer radical polymerization make it a rapidly developing area of synthetic polymer chemistry. Here, the fundamentals of the technique are discussed, along with how it can be used to synthesize macromolecules with controlled molecular architecture, and how their self-assembly can create nanostructured functional materials.

The latest from the literature
A sensor for detecting melamine has been developed; the stereochemistry of a guest is shown to affect the NMR signal of a host–guest complex allowing the measurement of stereochemical purity; and white phosphorus has been fragmented using carbenes.
Current issue
Bioanalytical chemistry
Article by Bernstein et al.Ion-mobility mass spectrometry has been used to identify and characterize the oligomeric assemblies of amyloid-β proteins under physiologically relevant conditions. Hexamers and dodecamers are formed only from Aβ42 proteins and the dodecamer is identified as a candidate for the primary toxic agent in the development of Alzheimer's disease.
