Significant questions regarding turbulence in quantum fluids, such as superfluid helium, remain unanswered owing to the inability to directly probe the local velocity in a manner quite common in the study of classical fluid turbulence. Using a novel visualization technique to measure the local...

The nuclear fuel cycle is the series of industrial processes that support the production of electricity in nuclear power reactors.  While the United States currently practices the ‘open’ fuel cycle in which used uranium fuel is not reprocessed or recycled, ‘closed’ fuel cycles...
