Researchers at the University of Illinois have found a way to apply self-healing technology to lithium-ion batteries to make them more reliable and last longer. The group developed a battery that uses a silicon nanoparticle composite material on the negatively charged side of the battery and a novel way to hold the composite together —…

Engineers are unveiling an upgrade to the transistor laser that could be used to boost computer processor speeds — the formation of two stable energy states and the ability to switch between them quickly. Modern computers are limited by a delay formed as electrons travel through the tiny wires and switches on a computer chip.…
