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.

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.

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.

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.

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.

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.

Improved data, models and analyses from Oak Ridge National Laboratory scientists and many other researchers in the latest global climate assessment report provide new levels of certainty about what the future holds for the planet and highlight the urgency of decarbonization to avoid the most severe impacts.

Nestled at the intersection of eastern Tennessee’s Anderson and Roane Counties, the Oak Ridge National Environmental Research Park is a living laboratory and a major resource for conducting ecological studies.

ORNL produces Th-228 for the Department of Energy’s Isotope Program in large quantities as a byproduct of the process to produce actinium-227. Researchers hope studies looking at different medical applications for the isotope will grow customer demand for it.

As the United States transitions to clean energy, the country has an ambitious goal: cut carbon dioxide emissions in half by the year 2030, if not before. One of the solutions to help meet this challenge is found at Oak Ridge National Laboratory as part of the Better Plants Program.
