Lanthanum barium copper oxide, or LBCO, was discovered in 1986 and was the first high temperature superconductor. (material-properties.org)
Xenon1
Following the first successful synthesis of xenon compounds in 1962, synthesis of krypton difluoride (KrF 2) was reported in 1963. (wikipedia.org)
Fission4
Krypton is one of the products of uranium fission. (wikipedia.org)
For example, the binding energy per nucleon for uranium is about 7.7 MeV and the products of the fission reaction of uranium, namely barium and krypton, have a binding energy of about 8.5 MeV per nucleon. (eduinput.com)
Thus when a uranium nucleus breaks up, as a result of a fission reaction, into barium and krypton, then energy at the rate of (8.5-7.6) = 0.9 MeV per nucleon is given out. (eduinput.com)
Nuclear fission can be illustrated by a simple nuclear reaction eg: when uranium is bombarded by neutron it splits into lighter nuclei Barium and Krypton. (tyrocity.com)
Neutrons4
It splits to make Barium and Krypton as well as relasing 3 neutrons each moving at a high speed which can split further Uranium atoms. (getrevising.co.uk)
If you break uranium-235 into two pieces, you get krypton-92, barium-141 plus two extra neutrons. (fusion4freedom.com)
In this example, a neutron reacts with uranium-235 to give krypton-92, barium-141, and 3 neutrons. (lynniezulu.com)
When U-235 Is Bombarded By Neutrons (the Small Blue Circles In The Image To The Left), It Splits And Produces Barium, Krypton, And More Neutrons. (unpad.ac.id)
Helium1
Solid krypton is white and has a face-centered cubic crystal structure, which is a common property of all noble gases (except helium, which has a hexagonal close-packed crystal structure). (wikipedia.org)
Further, the splitting of nuclei leads to the formation of Barium and Krypton nuclei and the series of reactions becomes infinite. (askanydifference.com)
Fluorine1
Compounds with krypton bonded to atoms other than fluorine have also been discovered. (wikipedia.org)
Naturally occurring krypton in Earth's atmosphere is composed of five stable isotopes, plus one isotope (78Kr) with such a long half-life (9.2×1021 years) that it can be considered stable. (wikipedia.org)
Lead1
Here we show that sealed single-walled CNTs filled with lead, barium and even krypton can be produced, and externally decorated with peptides to provide affinity for sub-cellular targets. (icmab.es)
Mass3
It is much more probable to break up into unequal fragments, and the most probable fragment masses are around mass 95 (Krypton) and 137 (Barium). (nuclear-power.com)
It may be remembered that the mass of both krypton and barium is less than that of the mass of uranium. (eduinput.com)
High3
Krypton light has many spectral lines, and krypton plasma is useful in bright, high-powered gas lasers (krypton ion and excimer lasers), each of which resonates and amplifies a single spectral line. (wikipedia.org)
From 1960 to 1983, the official definition of meter was based on the wavelength of one spectral line of krypton-86, because of the high power and relative ease of operation of krypton discharge tubes. (wikipedia.org)
Because of its high chemical reactivity, barium is never found in nature as a free element. (material-properties.org)
Source1
The primary commercial source of barium is baryte (also called barytes or heavy spar), a barium sulfate mineral with deposits in many parts of the world. (material-properties.org)
Element4
Krypton (from Ancient Greek: κρυπτός, romanized: kryptos 'the hidden one') is a chemical element with the symbol Kr and atomic number 36. (wikipedia.org)
Barium is the fifth element in group 2 and is a soft, silvery alkaline earth metal. (material-properties.org)
Krypton is characterized by several sharp emission lines (spectral signatures) the strongest being green and yellow. (wikipedia.org)
Highly1
Krypton is highly volatile and does not stay in solution in near-surface water, but 81Kr has been used for dating old (50,000-800,000 years) groundwater. (wikipedia.org)
