Kroto, Sir Harold Walter, 1939–, British chemist, Ph.D. Univ. of Sheffield, 1964. Kroto was a member of the faculty at Univ. of Sussex from 1967 to 2004 and is still an emeritus professor there. He has been a professor at Florida State Univ. since 2004. Kroto was corecipient of the 1996 Nobel Prize in Chemistry with Robert Curl and Richard Smalley for the discovery of fullerenes, which are carbon atoms bound in the form of a structure that looks like a soccer ball. The work opened up new avenues of research in chemistry, including efforts to exploit the unique properties of these materials in nanotechnology.
