Smart Lighting: New LED Drops the 'Droop'

(PhysOrg.com) -- Researchers at Rensselaer Polytechnic Institute have developed and demonstrated a new type of light emitting diode (LED) with significantly improved lighting performance and energy efficiency.

Unzipping Carbon Nanotubes Can Make Graphene Ribbons

(PhysOrg.com) -- By "unzipping" carbon nanotubes, researchers have shown how to make flat graphene ribbons. Graphene, which is a one-atom-thick sheet of carbon that looks like chicken wire, has unique electrical properties ...

Researchers create very small sensor using 'white graphene'

Researchers from TU Delft in The Netherlands, in collaboration with a team at the University of Cambridge (U.K.), have found a way to create and clean tiny mechanical sensors in a scalable manner. They created these sensors ...

Ultrashort light pulses for fast 'lightwave' computers

Extremely short, configurable "femtosecond" pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today's electronics.
