Newly discovered sheets of nanoscale 'cubes' found to be efficient catalysts
Researchers from Tokyo Metropolitan University have created sheets of transition metal chalcogenide "cubes" connected by chlorine atoms. While sheets of atoms have been widely studied, e.g. graphene, the team's work breaks new ground by using clusters instead. The research is published in the journal Advanced Materials. ⌘ Read more
