We examine the history of carbon nanotubes, starting with Sumio Iijima in 1990. Or maybe Howard Tennett. Or maybe A.M. Nesterenko, N.F. Kolesnik, Yu.S. Akhmatov, V.I. Suhomlin, and O.V. Prilutskii, or maybe John Abrahamson, Peter Wiles, and Brian Rhoades. Or maybe others. Whoever it was, we then look at what mechanical, electrical, and optical properties are so interesting about nanotubes, then some practical applications for them.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!
