Lasers, heat and a notoriously tricky element are at the center of a quiet revolution in how the United States plans to power ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are breathing new life into the scientific ...

The environment and human health are adversely affected by plutonium, even in minute quantities. The isotope plutonium-244 provides clues about nucleosynthesis and neutron star mergers, so plutonium ...

For decades, humanity has sent robotic explorers far beyond Earth’s comfort zone—into places where sunlight is weak, nights ...

Oxidation is the process where atoms lose electrons during a chemical reaction. Among the radioactive elements, neptunium and plutonium are much harder to oxidize than uranium. To study these elements ...

A team of scientists has discovered a new, stable form of plutonium – and done so by accident. The famously unstable element is tricky to transport, store and dispose of, but the find could lead to ...

Elements that do not exist in nature—that have been created in a laboratory—are unstable. After hours or days of one element bombarding another with enough energy for both to fuse, the resulting new ...

“Uranium 235 and plutonium can be denatured; such denatured materials do not readily lend themselves to the making of atomic explosives, but. . . can be used for the peaceful applications of atomic ...
