Evidence of Hollow Golden Cages
On the Cover: Geometric structures of molecular cages consisting of 16-18 gold atoms, representing some of the first free-standing hollow metal cages isolated in the laboratory. The length scale of such “bucky-gold” cages typically ranges from 5 to 7 Å, which can accommodate a guest atom inside. Image courtesy of the Office of Research (University of Nebraska, Lincoln).
