Residential LEDs use at least 75% less energy and last 25 times longer than incandescent bulbs, but R&D challenges still exist for LED lighting. However, new materials research continues to push LED technologies further forward.
Read MoreIBM scientists report that they have developed a simple technique to peel extremely thin layers of gallium nitride from a bulk wafer of the material—a breakthrough in manufacturing techniques for this expensive material.
Read MoreEngineers at the University of California San Diego have developed a neodymium-loaded magnetic ink that can be used to print batteries, circuits, and other devices that, if broken or damaged, can self-heal themselves in a matter of milliseconds.
