Plumbene, graphene's latest cousin, realized on the 'nano water cube'

Researchers have created 'plumbene,' a 2D-honeycomb sheet of lead atoms. As a surprising by-product, the research group also observed a nanoscale palladium-lead Weaire-Phelan-like bubble structure in the palladium substrate -- like the 'Water Cube' of the 2008 Olympics in Beijing.
