Nature Superoxide gives lithium-air batteries a jolt
In a recent experiment, Argonne battery scientists Jun Lu, Larry Curtiss and Khalil Amine, along with American and Korean collaborators, were able to produce stable crystallized lithium superoxide (LiO2) instead of lithium peroxide during battery discharging. Unlike lithium peroxide, lithium superoxide can easily dissociate into lithium and oxygen, leading to high efficiency and good cycle life.

Nature Communications One direction: Researchers grow nanocircuitry with semiconducting graphene nanoribbons
Researchers from the University of Wisconsin at Madison are the first to grow self-directed graphene nanoribbons on the surface of the semiconducting material germanium. This allows the semiconducting industry to tailor specific paths for nanocircuitry in their technologies. Confirmation of the findings was done at Argonne's Center for Nanoscale Materials.

Science Team announces breakthrough observation of Mott transition in a superconductor
An international team of researchers announced today in Science the observation of a dynamic Mott transition in a superconductor. The discovery experimentally connects the worlds of classical and quantum mechanics and illuminates the mysterious nature of the Mott transition. It also could shed light on non-equilibrium physics, which is poorly understood but governs most of what occurs in our world. The finding may also represent a step towards more efficient electronics based on the Mott transition.
