Gadolinium is a chemical element; it has symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with ...
Fields. Chemistry. Jean Charles Galissard de Marignac (24 April 1817 – 15 April 1894) was a Swiss chemist whose work with atomic weights suggested the possibility of isotopes and the packing fraction of nuclei. His study of the rare earth elements led to his discovery of ytterbium in 1878 and co-discovery of gadolinium in 1880. [1][2][3]
Box office. $123.7 million [2] The Time Machine is a 2002 American post-apocalyptic science fiction action adventure film loosely adapted by John Logan from the 1895 novel of the same name by H. G. Wells and the screenplay of the 1960 film of the same name by David Duncan. Arnold Leibovit served as executive producer, and Simon Wells, the great ...
Johan Gadolin (5 June 1760 – 15 August 1852) [1] was a Finnish chemist, physicist and mineralogist. Gadolin discovered a "new earth" containing the first rare-earth compound yttrium, which was later determined to be a chemical element. He is also considered the founder of Finnish chemistry research, as the second holder of the Chair of ...
Edward Leedskalnin (Latvian: Edvards Liedskalniņš) (January 12, 1887 – December 7, 1951) was a Latvian immigrant to the United States and self-taught engineer who single-handedly built the Coral Castle in Florida, added to the National Register of Historic Places in 1984. [2] Leedskalnin was also known for developing theories of magnetism.
Crystal class. Prismatic (2/m) (same H-M symbol) Space group. P21 /n. Gadolinite, sometimes known as ytterbite, is a silicate mineral consisting principally of the silicates of cerium, lanthanum, neodymium, yttrium, beryllium, and iron with the formula (Ce,La,Nd,Y)2FeBe2Si2O10. It is called gadolinite- (Ce) or gadolinite- (Y), depending on the ...
Gadodiamide is one of the main GBCA associated with nephrogenic systemic fibrosis (NSF), a toxic reaction occurring in some people with kidney problems. [6] No cases have been seen in people with normal kidney function. [7] A 2015 study found gadolinium deposited in the brain tissue of people who had received gadodiamide. [8]
Gadolinium (III) containing MRI contrast agents (often termed simply "gado" or "gad") are the most commonly used for enhancement of vessels in MR angiography or for brain tumor enhancement associated with the degradation of the blood–brain barrier (BBB). [3][4] Over 450 million doses have been administered worldwide from 1988 to 2017. [5]
