A new joint innovation by the National Physical Laboratory (NPL) and the University of Cambridge could pave the way for redefining the ampere in terms of fundamental constants of physics. The world’s first graphene single-electron pump (SEP), described in Nature Nanotechnology, provides the speed of electron flow needed to create a new standard for electrical current [...]
Scientists have found that Chicago’s air is infested with chemicals courtesy of airborne compounds that are traveling as far as the Arctic. The chemicals, called cyclic siloxanes, are toxic to aquatic life. Where do they come from? From chemicals in deodorants, lotions and conditioners. “These chemicals are just everywhere,” said Keri Hornbuckle, an engineering professor at the [...]
