Researchers at Koç University, Turkey, have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt. Luminous efficiency is a measure of how well a light source uses power to generate light. With further development, the new LEDs could reach efficiencies over 200 lumens per watt, making them a […]

A Louisiana Tech University and University of Texas at Arlington team of professors and Louisiana Tech graduate students have created a hybrid nanomaterial that can be used to convert light and thermal energy into electrical current as a thermoelectric generator. The team has synthesized a combination of copper sulfide nanoparticles and single-walled carbon nanotubes.  They […]
