Researchers at Penn State, the Department of Energy’s Oak Ridge National Laboratory and Lockheed Martin Space Systems Company have developed methods to control defects in two-dimensional materials, such as graphene, that may lead to improved membranes for water desalination, energy...
The SNS LINAC is the most powerful proton-pulsed accelerator in the world.
The first of its kind superconducting linear particle accelerator (LINAC) built for the Spallation Neutron Source (SNS) at the Department of Energy’s Oak Ridge National Laboratory is now celebrating 10 years of successful operations. The world-leading machine, which took 7 years...
ORNL researcher Xiaobing Liu  works in the laboratory’s Building Technologies Research and Integration Center.

As a boy growing up in China, Xiaobing Liu knew all about Oak Ridge and the World War II Manhattan Project. He had no idea that he would one day work at DOE’s Oak Ridge National Laboratory, the Secret City’s successor. Liu is a lead researcher in geothermal heat pump (GHP) techn...
