'Butterfly-shaped' palladium subnano cluster built in 3-D

Miniaturization is the watchword of progress. Nanoscience, studying structures on the scale of a few atoms, has been at the forefront of chemistry for some time now. Recently, researchers at the University of Tokyo developed the new strategy to construct sub-nanosized metal aggregates, building up small metal clusters into grander 3-D architectures. Their creations could have real industrial value.
