Discovery of Bucky Or at least how I remember it!!

How it all started Rick Smalley develops supersonic jet techniques (70s & 80s) Bob Curl (Rice) and Harry Kroto (Sussex) talk at a Conference in Austin, TX in 1984 Sean O’Brien and Jim Heath begin grad school at Rice: Fall 1984 Old Chemistry Building at Rice

Laser Vaporization Cluster Source Sean O’Brien designed this…

Cluster Source

First Published work at Exxon on Carbon Clusters

Why is C 60 ion so large? + From “Designing the Molecular World” by Phillip Ball, Princeton, 1994

Buckminsterfullerene!! Sept. 1985

Nobel Prize in Chemistry “for their discovery of fullerenes” January 6, 1997 C&EN

Jim Heath then… Now Joe built this!!!
