Feeding your face In their Communication on page 2354 ff., Y. Xia and co-workers show that it is possible to shape-selectively grow bimetallic palladium–silver nanocrystals. By limiting the supply of silver atoms (red) nucleation and growth occurs on only one, or a few, of the six equivalent faces of a cubic palladium seed, as represented by the presence of hungry and feeding frogs.
