Scientists from SLAC, Stanford and Berkeley Lab grew sheets of an exotic material in a single atomic layer and measured its electronic structure for the first time. They discovered it's a natural fit for making thin, flexible light-based ...
By directly comparing three closely related catalysts, scientists at the Center for Molecular Electrocatalysis established that hydrogen production speed and efficiency are influenced by the molecules' structure and proton relay ...
