History and specificsEdit
This compound typically stored energy and could be used as an explosive. Trapped in a space anomaly, a freighter captain, one Bela Tyken, used anicium and yurium from his cargo bays to create a massive explosion. (TNG episode: "Night Terrors")
The display in "The Royale" did not make it clear if "Yu2" could be the abbreviation of a diatomic molecule of an element named yurium, or if it was "YU2", which would be yttrium with two molecules of uranium. The properties of yurium and keimium in the atmosphere of Theta VIII might have to do with the Kei/Yuri factor, mentioned in the same scan.
