Known for Co-discoverer of the heaviest elements in the periodic table; element oganesson named after him

Yuri Tsolakovich Oganessian (Russian: Ю́рий Цола́кович Оганеся́н, Armenian: Յուրի Ցոլակի Հովհաննիսյան; born 14 April 1933) is a Russian nuclear physicist of Armenian descent.[1] Oganessian is considered the world's leading researcher in superheavy elements.[2] He and his team discovered the heaviest elements in the periodic table.[3][4]

Career[edit]

At age 28, he joined the group of Georgy Flyorov (Flerov) at the Joint Institute for Nuclear Research in Dubna.[2]

Oganessian is the scientific leader of the Flerov Laboratory of Nuclear Reactions (FLNR).[5] He invented cold fusion in one-atom-at-a-time nucleosynthesis (not related to the similarly-named pseudoscientific claims) around 1970 and pioneered hot fusion in the late 1990s.[2] In 2009, scientists in the United States confirmed Oganessian's team's discovery of flerovium over a decade before.[6] He is a researcher in islands of stability. He continues to search olivine in pallasites hoping to find superheavy elements (or their fission tracks) in nature.[2]

In November 2016, IUPAC announced that element 118 would be named oganesson to honor Oganessian.[7][8][9] Prior to this announcement, a dozen elements had been named after people,[10] but of those, only seaborgium was likewise named while the person (Glenn Seaborg) was alive.
