(PhysOrg.com) -- Research engineers at Yale University have succeeded in building a mechanical memory switch that is controlled and then read by lasers. In their paper published in Nature Nanotechnology, the team, led by ...
(PhysOrg.com) -- The ability to control light forms the basis of many technologies, from microscopy to optical computing. Now, a team of scientists from ETH in Zurich, Switzerland, has demonstrated that a single organic molecule ...
In a recent article in Nano Letters, CNST researchers describe a new high-contrast, low operating-voltage, electrochemical optical switch that uses a volume of active dye orders-of-magnitude smaller than that of conventional ...
