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

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 ...

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 ...

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

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, ...

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 ...

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, ...

Superconductivity, a state where metals lose their electrical resistance, has been for a long time a dream of physicists. It could change the way we use energy and allow us to do things like levitate ...

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 ...

In a recent paper published in The European Physical Journal D, researchers from Johannes Gutenberg University Mainz, Germany, have demonstrated a method for more precise ionization measurements of ...
