LED lighting cuts costs for greenhouse tomato growers

Supplemental light-emitting diode (LED) lighting treatment can help greenhouse tomato growers reduce energy cost without affecting fruit quality attributes, new research suggests.

New QD technology to make screens brighter

Researchers from the University of Illinois at Urbana-Champaign, have developed a new method to extract more polarised light from quantum dots (QDs) over a large-scale area.

Artificial graphene could revolutionize electronics

Researchers have created a new breed of ultra thin super-material, "artificial graphene", which should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher performance photovoltaic cells, lasers or LED lighting.

New research enables brighter LED lights

Researchers, including one of Indian-origin, have made it possible to optimise phosphors - a key component in white LED lighting - allowing for brighter, more efficient lights.
