Quick detection of uranium isotopes helps safeguard nuclear materials

DOE/Oak Ridge National Laboratory

Analytical chemists at the Department of Energy’s Oak Ridge National Laboratory have developed a rapid way to measure isotopic ratios of uranium and plutonium collected on environmental swipes, which could help International Atomic Energy Agency analysts detect the presence of undeclared nuclear activities or material.

ORNL fusion scientists are working to make measurements of plasma disruption mitigation methods more accurate

DOE/Oak Ridge National Laboratory

A team of fusion researchers at the Department of Energy’s Oak Ridge National Laboratory used datasets from measurements on the Joint European Torus, or JET, tokamak to model an improved method for quantifying the amount of plasma-radiated power during a disruption of normal operations.

Brown takes new role with Climate Change Science Institute at ORNL

DOE/Oak Ridge National Laboratory

Marilyn Brown of the Georgia Institute of Technology recently began a joint faculty appointment, or JFA, with the Climate Change Science Institute at the Department of Energy’s Oak Ridge National Laboratory. As an internationally recognized leader in climate solutions and energy policy, Brown will collaborate with ORNL to apply insights from global climate science to inform regional strategies that reduce carbon emissions and equitably address impacts on communities.

Energy Secretary Granholm visits ORNL in virtual tour of world-class science facilities

DOE/Oak Ridge National Laboratory

On Sept. 28, U.S. Secretary of Energy Jennifer Granholm joined leadership and top scientists and engineers online at Oak Ridge National Laboratory for a two-hour whirlwind tour. At 14 stops, researchers highlighted the lab’s world-class facilities and projects that enable leading-edge scientific discoveries and innovations that address some of the nation’s most compelling scientific and technical challenges.

Perfecting the pellet

DOE/Oak Ridge National Laboratory

A team of experts at Oak Ridge National Laboratory is taking aim at one of the biggest challenges facing the international ITER fusion facility: turning cold gas into wine-cork-sized, solid pellets to help keep ITER’s plasma in check.

Microbial “theft” enables breakdown of methane, toxic methylmercury

DOE/Oak Ridge National Laboratory

A team led by the Department of Energy’s Oak Ridge National Laboratory and the University of Michigan has discovered that certain bacteria can steal an essential compound from other microbes to break down methane and toxic methylmercury in the environment.

Correlated electrons ‘tango’ in a perovskite oxide at the extreme quantum limit

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A team led by the Department of Energy’s Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially “dancing.” Straining the material creates an electronic band structure that sets the stage for exotic, more tightly correlated behavior – akin to tangoing – among Dirac electrons, which are especially mobile electric charge carriers that may someday enable faster transistors.

Laser treatment shows potential for reducing industrial chemical processing for vehicles

DOE/Oak Ridge National Laboratory

A multidisciplinary team of scientists at the Department of Energy’s Oak Ridge National Laboratory has applied a laser-interference structuring, or LIS, technique that makes significant strides toward eliminating the need for hazardous chemicals in corrosion protection treatments. The novel application of the LIS method answers a call from the U.S. Department of Defense for research projects that explore nonchemical alternatives for corrosion protection in military vehicles and aircraft systems.
