Researchers at the Department of Energy's Oak Ridge National Laboratory are breathing new life into the scientific understanding of neptunium, a unique, radioactive, metallic element—and a key ...

This week's element is neptunium, which has the atomic symbol Np and atomic number 93. Neptunium was named for the planet Neptune, the next planet away from the sun after Uranus (which was uranium's ...

Three trial uranium-plutonium MOX fuel assemblies containing americium-241 and neptunium-237 have completed three fuel ...

Physicists have gained new insight into the origins of superconductivity -- a property of metals where electrical resistance vanishes -- by studying exotic chemical compounds that contain neptunium ...

Scientists first created the artificial element neptunium in 1940, around the time they made the first atoms of plutonium. But because plutonium turned out to be so much better for nuclear weapons, ...

Edwin McMillan and Philip H. Abelson first produced neptunium at the University of California in 1940. The scientists bombarded uranium-238 atoms with neutrons to chemically produce neptunium-239, ...

Not much is known about the properties of neptunium, a highly radioactive man-made material that is a byproduct of nuclear reactors, except that it emits alpha, beta and gamma radioactivity. The ...

Jim Ibers talks about neptunium, an element that has remained largely unnoticed despite the flurry of activity devoted to its neighbours in the periodic table, uranium and plutonium. The actinides, ...

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 ...
