The superconducting properties of YBa 2 Cu 3 O 7−x are sensitive to the value of x, its oxygen content. Only those materials with 0 ≤ x ≤ 0.65 are superconducting below T c , and when x ~ 0.07 , the material superconducts at the highest temperature of 95 K , [ 6 ] or in highest magnetic fields: 120 T for B perpendicular and 250 T for B ...
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 ...
The term "yBa" was already used in 1994 [8] and later used by Simon Ford in a feature "Myth Making" in March 1996 in Art Monthly magazine. [17] Art dealer Jay Jopling began to represent YBAs Jake & Dinos Chapman, Tracey Emin, Marcus Harvey, Damien Hirst, Gary Hume, Marc Quinn, Gavin Turk and Sam Taylor-Wood, whom he married in 1998.
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 ...
267th Chemical Company operations building on Okinawa. Mascot Thumper is depicted on the sign. On April 20, 1945, the 267th Chemical Service Platoon (SVC) was activated at Fort Richardson, Alaska, but the platoon was inactivated on Nov. 1 of the same year, primarily because of the end of World War II.

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 Yusuf Bin Ahmed Kanoo Group (also known as: YBA Kanoo Group) is a privately held business conglomerate established in 1890. [1] It is one of the largest family-owned multinationals [2] in the Middle East, with complementary businesses and strategic partnerships. It has a physical presence across the Middle East, North Africa, Europe and ...
Sensation installed at Brooklyn Museum (October 1999 – January 2000). Sensation was an exhibition of the collection of contemporary art owned by Charles Saatchi, including many works by Young British Artists (YBAs), which first took place 18 September – 28 December 1997 at the Royal Academy of Arts in London.
