Lanthanum was discovered in 1839 by Swedish chemist Carl Gustav Mosander, when he partially decomposed a sample of cerium nitrate by heating and treating the resulting salt with dilute nitric acid. From the resulting solution, he isolated a new rare earth he called lantana. Lanthanum was isolated in relatively pure form in 1923. The word lanthanum comes from the Greek lanthanein, to lie hidden. ...

Cerium is a chemical element in the periodic table that has the symbol Ce and atomic number 58. Cerium - Notable characteristics. Cerium is a silvery metallic element, belonging to the lanthanide group. It is used in some rare-earth alloys. It resembles iron in color and luster, but is soft, and both malleable and ductile. It tarnishes readily in the air. Only europium is more reactive than cerium among rare earth elements. Alkali solutions and dilute and concentrated acids attack the metal rapidly. ...

Unconventional superconductors are materials that display superconductivity but that do not conform to BCS theory and Nikolay Bogolyubov theory or its extensions. The first unconventional triplet superconductor, organic material (TMTSF)2PF6, was discovered by Denis Jerome and Claus Bechgaard in 1979. Recent experimental works by Paul Chaikin's and Michael Naughton's groups as well as theoretical analysis of their data by Andrei Lebed have firmly confirmed unconventional triplet nature of superc ...

For fission of Uranium-235 the most common radioactive fission products include isotopes of Iodine, Caesium, Strontium, Xenon and Barium. Many of the fission products decay through very shortlived isotopes to form stable isotopes, but also a considerable number of the radioisotopes have half lives longer than a day. Some fission products are useful as beta and gamma sources in medicine and industry, see common beta emitters and commonly used gamma emitting isotopes for more details. Few fission products are alpha particle emitters, but ...

If a graph of the mass or mole yield of fission products against the atomic mass of the fragments is drawn then it has two peaks, one in the area strontium through to palladium and one at iodine through to neodymium. This is due to the fact that the fission event causes the nucleus to split in an asymmetric manner.[1] Yield vs. Z - This is a typical distribution for the fission of uranium. Please note in the calculations used to make this graph the activation of fission products was ignored and the fission was assumed to occur in a single moment rather than a length of time. In this bar chart results are ...

In a nuclear reactor, the buildup of fission products as reaction poisons in the fuel eventually leads to loss of efficiency, and in some cases to instability. They contribute most of the short and medium term radioactivity of high-level nuclear waste produced from spent reactor fuel. Depending on the quality of the fuel cladding can appear in the primary coolant. In a well designed power reactor running under normal conditions the radioactivity of the coolant is very low, in the BWR reactors the bulk of the activity in the coolant is due to ...

The mixture of radioactive fission products found in the fall out from a nuclear bomb are very different in nature to those found in spent power reactor fuel. This is because the reactor fuel will have had more time for the short lived isotopes to decay. Fission product - Iodine. At least three isotopes of iodine are important. 129I, 131I and 132I A counter measure against the shortlived iodine isotopes (such as 131I), is to take potassium iodide by mouth. ...
