The Alan G. MacDiarmid NanoTech Institute was established in 2001 when Bay Baughman, a pioneering nanotechnologist, became the Robert A. Welch Distinguished Chair in Chemistry and director of the university's NanoTech Institute. In 2007, it was renamed in memory of the late Alan G. MacDiarmid, who shared the 2000 Nobel Prize in chemistry with Alan Heeger and Hideki Shirakawa.
