Science World's smallest neutrino detector finds big physics fingerprint
After more than a year of operation at the Department of Energy's Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world's smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter. The research, performed at ORNL's Spallation Neutron Source and published in the journal Science, provides compelling evidence for a neutrino interaction process predicted by theorists 43 years ago, but never seen.

Nature Communications Built from the bottom up, nanoribbons pave the way to 'on-off' states for graphene
A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications. Graphene nanoribbons, mere billionths of a meter wide, exhibit different electronic properties than two-dimensional sheets of the material. 'Confinement changes graphene's behavior,' said An-Ping Li, a physicist at the Department of Energy's Oak Ridge National Laboratory.
