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).
This location is described as having "tremendous potential" for rare-earth elements and yttrium (REY), according to a study published in Scientific Reports. [54] "This REY-rich mud has great potential as a rare-earth metal resource because of the enormous amount available and its advantageous mineralogical features," the study reads.
The most famous ReBCO is yttrium barium copper oxide, YBa 2 Cu 3 O 7−x (or Y123), the first superconductor found with a critical temperature above the boiling point of liquid nitrogen. [10] Its molar ratio is 1 to 2 to 3 for yttrium, barium, and copper and it has a unit cell consisting of subunits, which is the typical structure of perovskites .
A rare species is a group of organisms that are very uncommon, scarce, or infrequently encountered. This designation may be applied to either a plant or animal taxon, and is distinct from the term endangered or threatened. Designation of a rare species may be made by an official body, such as a national government, state, or province.
The Physical Impossibility of Death in the Mind of Someone Living is an artwork created in 1991 by Damien Hirst, an English artist and a leading member of the "Young British Artists" (or YBA). It consists of a preserved tiger shark submerged in formalin in a glass-panel display case .
"Golden Library" thought to contain rare Greek, Latin, and Egyptian works from the libraries of Constantinople and Alexandria, as well as 2nd-century CE Chinese texts and manuscripts from Ivan IV's own era. La Noche Triste treasure: Partially Confirmed 1520 —
Yba'sokug is a great beast that is said to be come to devour the world, sending depravity before him in the form of his heralds. He is depicted as a froglike creature with a great multitude of eyes. He is depicted as a froglike creature with a great multitude of eyes.
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.
