Optimizing atomic neighborhoods for speedier chemical reactions
Scientists have discovered that for palladium-nickel catalysts, certain surface characteristics, measured at the atomic level, sped the creation of carbon dioxide from carbon monoxide. This type of atomic detail has not been available by traditional studies and can aid the cycle of catalyst design by optimizing for structural parameters at the nearest neighbor level of an atomic environment.

Multimetal nanoframes improve catalyst performance
Researchers synthesized a highly active and durable class of electrocatalysts by exploiting the structural evolution of solid Pt-Ni bimetallic nanocrystals into porous cage-like structures or nanoframes. This approach to synthesizing the material is a significant advance towards realizing electrocatalysts with superior catalytic properties and lower cost.

'Explosive' atom movement is new window into growing metal nanostructures
Scientists at the US Department of Energy's Ames Laboratory expected to see slow, random movement when they dropped lead atoms on a lead-on-silicon surface. 'But what we saw? BOOM! Fast, explosive and organized!' said Michael Tringides, Ames Laboratory physicist. The unusual atom movement may represent a new way to grow perfect, tiny metal nanostructures for nanostransistors, nanoswitches, and nanomagnets.
