  2. Synthetic element - Wikipedia

    en.wikipedia.org/wiki/Synthetic_element

    Plutonium (Pu, atomic number 94), first synthesized in 1940, is another such element. It is the element with the largest number of protons (atomic number) to occur in nature, but it does so in such tiny quantities that it is far more practical to synthesize it. Plutonium is known mainly for its use in atomic bombs and nuclear reactors. [4]

  3. Synthesis of precious metals - Wikipedia

    en.wikipedia.org/wiki/Synthesis_of_precious_metals

    The radioactivity in MBq per gram of each of the platinum group metals which are formed by the fission of uranium. Of the metals shown, ruthenium is the most radioactive. Palladium has an almost constant activity, due to the very long half-life of the synthesized 107 Pd, while rhodium is the least radioactive.

  4. Plutonium - Wikipedia

    en.wikipedia.org/wiki/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]

    Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.

  7. Weapons-grade nuclear material - Wikipedia

    en.wikipedia.org/wiki/Weapons-grade_nuclear_material

    Plutonium recovered from LWR spent fuel, while not weapons grade, can be used to produce nuclear weapons at all levels of sophistication, [25] though in simple designs it may produce only a fizzle yield. [26] Weapons made with reactor-grade plutonium would require special cooling to keep them in storage and ready for use. [27]

    The real Doc Magnus and the Metal Men battled one of the robots each and mutually destroyed each other. Platinum takes the Doc Robot and Plutonium robots to the Moon, where Plutonium is detonated. Aluminum Barium Calcium Plutonium Sodium Zirconium Platinum II Metal Men #3 (August–September 1963) An unsuccessful recreation of Platinum (Tina ...

  9. Ionized jewelry - Wikipedia

    en.wikipedia.org/wiki/Ionized_jewelry

    An Ionized bracelet, or ionic bracelet, is a type of metal bracelet jewelry purported to affect the chi of the wearer. No claims of effectiveness made by manufacturers have ever been substantiated by independent sources, and the US Federal Trade Commission (FTC) has found the bracelets are "part of a scheme devised to defraud".
