Cover Picture: A New Highly Durable Pt Nanocatalyst for PEM Fuel Cells: the Multiarmed Star-like Nanowire Single Crystal. (Angew. Chem. Int. Ed. 2/2011) (Page 422)

The multiarmed star-like 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  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.

Cover Picture: Controllable Synthesis of Graphene-based Titanium Dioxide Nanocomposites by Atomic Layer Deposition. (Nanotechnology 22/2011) (Page 165602)

TiO₂/graphene nanocomposites were synthesized by Atomic layer deposition (ALD). The as-deposited TiO₂ was tunable in morphologies and structural phases by this technique.  The resultant TiO₂–GNS nanocomposites have great potentials for many applications, such as photocatalysis, lithium-ion batteries, fuel cells, and sensors.
