(PhysOrg.com) -- Many versions of early Earth history offer visions of a hot melting mix of materials which would have resulted, after cooling, in a smooth blend of ingredients, much a like a cake after beating and baking. ...
Scientists at the University of Groningen used a silver sawtooth nanoslit array to produce valley-coherent photoluminescence in two-dimensional tungsten disulfide flakes at room temperature. Until now, this could only be ...
