Staying power: A new class of cathode catalysts based on supportless Pt (see picture, left) and PtPd nanotubes (NTs) is introduced. These materials have remarkable durability (right; CV=cyclic voltammetry, ECSA=electrochemical surface area) and high catalytic activity. They have the potential to circumvent most of the degradation pathways of current Pt/C and Pt-black catalysts.

Abstract A study of O 2 reduction in 1 M NaOH solution at gas diffusion electrodes made from carbon supported Pt and Pt/Ru catalysts is reported. Two Tafel regions were observed...
A perfect combination: The association of a chromium(III) trimeric building unit and 1,3,5-benzenetricarboxylate led to the powdered solid MIL-100. Simulations provided a crysta...
Decorated tiles: Self-assembling DNA nanostructures can be used to form addressable, size-controlled nanoarrays with a variety of programmed patterns. Arrays of DNA cross-shaped...
We demonstrated that platinum (Pt) oxygen-reduction fuel-cell electrocatalysts can be stabilized against dissolution under potential cycling regimes (a continuing problem in veh...
Iron muscles into mussels: Marine mussels adhere to rocks with a protein-based glue. An iron complex is the key curing agent in this adhesive, and the iron center is coordinated...
