Wagon-wheel Rotelle Shape Make Better LEDs

‘Rotelle’ molecules depolarize light for LEDs; more efficient than ‘spaghetti’ One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or LED. University of Utah physicists believe they have solved the problem by creating a new organic molecule that is shaped like rotelle – wagon-wheel pasta – rather than spaghetti. The rotelle-shaped molecule – known as…

Creating Electricity with Caged Atoms

At the Vienna University of Technology, a new class of thermoelectric materials has been discovered; Due to a surprising physical effect they can be used to create electricity more efficiently A lot of energy is wasted when machines turn hot, unnecessarily heating up their environment. Some of this thermal energy could be harvested using thermoelectric materials; they create electric current when they are used to bridge hot and cold objects. At the Vienna University of Technology (TU Vienna), a new…
