You might have tried to balance a ping-pong ball floating above your mouth or you might have seen a demo in a classroom or science museum where a jet of compressed air keeps a ball floating above the ground, seemingly defying gravity. A pair of grad students at the University of Illinois at Urbana-Champaign have ... »

Researchers, from the University of Illinois at Urbana-Champaign, are also working on capsule additives designed to heal failures in lithium-ion battery electrodes, to prevent the short-circuiting that can sometimes cause a fire. Capsules filled with conductive nanotubes that rip open under mechanical stress could be placed on circuit boards in the areas that are important ... »

A team of researchers at the University of Illinois has created the world’s first acoustic “superlens”. It is an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology. According to the results, the acoustic system is analogous to an inductor-capacitor circuit. The ... »
