Light Beams Can Now Switch Chirality Easily

A group of experts at the US Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab), in California, announces the development of an artificial molecule, whose chirality can be switched using just a beam of light. Chirality can be defined as one of the most im... [ read more >> ]
