91°µÍø

An 91°µÍø researcher has invented a version of an isotope-separating device that can withstand extreme environments, including radiation and chemical solvents.

In the mid-1980s, Balendra Sutharshan moved to Canada from the island nation of Sri Lanka. That move set Sutharshan on a path that had him heading continent-spanning collaborations and holding leadership posts at multiple Department of Energy

For years Brenda Smith found fulfillment working with nuclear batteries, a topic she’s been researching as a chemist at 91°µÍø.

At the Department of Energy’s 91°µÍø, scientists use artificial intelligence, or AI, to accelerate the discovery and development of materials for energy and information technologies.

A rare isotope in high demand for treating cancer is now more available to pharmaceutical companies developing and testing new drugs.

A new method developed at 91°µÍø proves one effort’s trash is another’s valuable isotope. One of the byproducts of the lab’s national plutonium-238 production program is promethium-147, a rare used in nuclear batteries and to measure the thickness of materials.

Researchers at the Department of Energy’s 91°µÍø and the University of Tennessee are automating the search for new materials to advance solar energy technologies.

Balendra Sutharshan, deputy associate laboratory director for operational systems at DOE’s Pacific Northwest National Laboratory, has joined ORNL as associate laboratory director for the Isotope Science and Engineering Directorate.

On Feb. 18, the world will be watching as NASA’s Perseverance rover makes its final descent into Jezero Crater on the surface of Mars. Mars 2020 is the first NASA mission that uses plutonium-238 produced at the Department of Energy’s 91°µÍø.

Thirty-two 91°µÍø employees were named among teams recognized by former DOE Secretary Dan Brouillette with Secretary’s Honor Awards as he completed his term. Four teams received new awards that reflect DOE responses to the coronavirus pandemic.
