(Phys.org) —If you've been lucky enough to catch all the green lights as you drive down a busy street, you may have been benefiting from intentional synchronization called a "green wave." The green wave concept has been ...
A tailored layer of plasmonic nanoparticles can be introduced into the epoxy casing of a light-emitting diode (LED) to improve the device's light output, to benefit energy savings and boost the LED lifetime. In a new report ...
Researchers at the University of Illinois at Urbana-Champaign have constructed a quantum-mechanical state in which the colors of three photons are entangled with each other. The state is a special combination, called a W ...
