The Ploutonion at Hierapolis (Ancient Greek: Πλουτώνειον Ploutōneion, [2] lit "Place of Pluto"; Latin: Plutonium) or Pluto's Gate [3] was a ploutonion (a religious site dedicated to the god Pluto) in the ancient city of Hierapolis near Pamukkale in modern Turkey's Denizli Province. The site was discovered in 1965 by Italian ...
Pluto's Gate ("Old Plutonion" [1] adjacent to the Temple of Apollo) at Hierapolis. A ploutonion [pronunciation?] (Ancient Greek: Πλουτώνιον, lit. "Place of Plouton") is a sanctuary specially dedicated to the ancient Greek god Plouton (i.e., Hades).
In February 1940, Glenn Seaborg and Edwin McMillan produced plutonium-239 by bombarding uranium with deuterons. This produced neptunium, element 93, which underwent beta-decay to form a new element, plutonium, with 94 protons. [4] Kennedy built a series of detectors and counters to verify the presence of plutonium.

Plutonium–gallium–cobalt alloy (PuCoGa 5) is an unconventional superconductor, showing superconductivity below 18.5 K, an order of magnitude higher than the highest between heavy fermion systems, and has large critical current. [46] [50] Plutonium–zirconium alloy can be used as nuclear fuel. [51]
Some months vary in length by a day, as well. The months originally had very descriptive names, such as Ziv (meaning light) and Ethanim (meaning strong, perhaps in the sense of strong rain - i.e. monsoon), with Canaanite origins, but after the Babylonian captivity, the names were changed to the ones used by the Babylonians.
Plutonium in the delta (δ) phase [8] normally exists in the 310 °C to 452 °C range but is stable at room temperature when alloyed with a small percentage of gallium, aluminium, or cerium, enhancing workability and allowing it to be welded in weapons applications. The δ phase has more typical metallic character and is roughly as strong and ...
Plutonium(IV) oxide, or plutonia, is a chemical compound with the formula Pu O 2. This high melting-point solid is a principal compound of plutonium . It can vary in color from yellow to olive green, depending on the particle size, temperature and method of production.
