The multiarmed starlike platinum nanowires shown are used as a new type of
electrocatalyst to address both activity and durability challenges for proton exchange
membrane (PEM) fuel cells. In their Communication on page 422 ff., X. Sun et al.
present a very simple strategy for the synthesis of such nanowires on carbon. The
activity and durability of the new system is much improved over that of the
commercial catalyst made of Pt nanoparticles on carbon supports.
Organization of Colloids
In their Review on page 360 ff., A. Stein et al. highlight recent experimental and
theoretical progress in the assembly of colloids. Examples include the formation of
colloidal analogues of molecules, clusters, and chains, as well as particles with
anisotropic form.
Single-Cell Genetic Analysis
R A. Mathies and co-workers describe in their Communication on page 390 ff. a
robust agarose-microdroplet method for detecting and sequencing multiple genetic
targets from single cells in a scalable manner.
Control of Selectivity
The application of a supramolecular strategy for the preorganization of alkene
substrates for selective rhodium-catalyzed hydroformylation is described by J. N. H.
Reek et al. in their Communication on page 396 ff.
