Metals Shape Up with a Little Help from Friends (2 of 2)

Caption

After etching away the carbon material left from the use of intermediary polymers to organize the metal nanoparticles, the platinum structure features large (0.01 micrometers) hexagonal pores. The illustration depicts the completed porous platinum structure. This nanostructured platinum is the product of a radically innovative method for shaping metals developed by Cornell researchers. These porous metal structures have the capability to transform the development of catalysts for fuels cells and materials for microchip fabrication.
