Uni Illinois researchers find cooling effect

Researchers from the University of Illinois may have found a way of creating transistors from graphene that have a unique self-cooling property. Current limitations of computer chips made from silicon revolve around the way they generate heat which often require an external cooling source. This affects the size of the chips and how efficient they can be. The new technique using graphene could deliver smaller, more powerful chips that could require little or no cooling at all.

University of Illinois intros quantum batteries

A physicist at the University of Illinois, Urbana-Champaign campus, says a new digital quantum battery can offer a huge increase in energy output and storage capacity. While the gains are theoretical at this point, the concept involves billions of nanoscale capacitors and relies on quantum effects that happen at the atomic scale to boost energy storage. According to Alfred Hubler, the new technology could result in batteries that can hold between two and 10 times more energy that today's best lithium-ion batteries.
