Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen [77 K (−196.2 °C; −321.1 °F)] at about 93 K (−180.2 °C; −292.3 °F).
Example of systems with short-range ordering of oxygen-vacancies include oxygen-deficient stoichiometries of the superconductors YBa 2 Cu 2 O 7−δ, Nd 2−x Ce x CuO 4−y; as well as perovskites and novel bismuth sillenites.
Yttrium is a key ingredient in the yttrium barium copper oxide (YBa 2 Cu 3 O 7, aka 'YBCO' or '1-2-3') superconductor developed at the University of Alabama in Huntsville and the University of Houston in 1987. [49] This superconductor is notable because the operating superconductivity temperature is above liquid nitrogen's boiling point (77.1 K ...
YBA or yba can refer to a number of things: Young British Artists, a movement of British artists in the 1980s and 1990s; Yala language, a language spoken in Ogoja, Nigeria, by ISO 639 code; Young Buddhist Association, an association of Buddhists in the U.S. Banff Airport, an airstrip near Banff, Alberta, Canada, by IATA code
The YBA-1 "Bass Master" circuit is very similar to the Fender Bassman, which in turn inspired the classic Marshall 1959 "Plexi" amplifier. [7] The column loudspeakers were designated "YSC-1" and two additional models were created: the "YSC-2" with fewer, larger drivers to obtain more low-frequency bass extension and the "YSC-3" which was a cut ...
Probably the first report of a polar metal was in single crystals of the cuprate superconductors YBa 2 Cu 3 O 7−δ. [4] [5] A polarization was observed along one (001) axis by pyroelectric effect measurements, and the sign of the polarization was shown to be reversible, while its magnitude could be increased by poling with an electric field. [6]
The uptake and loss of oxygen are reversible in YBa 2 Cu 3 O 7−x. A fully oxygenated orthorhombic YBa 2 Cu 3 O 7−x sample can be transformed into tetragonal YBa 2 Cu 3 O 6 by heating in a vacuum at temperature above 973 K (700 °C). [68] The preparation of Bi-, Tl- and Hg-based high-T c superconductors is more difficult than the YBCO ...
JoJo's Bizarre Adventure: All Star Battle [a] is a fighting game developed by CyberConnect2 and published by Bandai Namco Entertainment for PlayStation 3.Based on Hirohiko Araki's long-running manga series JoJo' s Bizarre Adventure, the game allows players to compete against each other using 40 characters taken from the first eight story arcs, as well as one guest character from another manga ...
