Fullerenes and carbon nanotubes, carbon compounds with spheroidal and tubular buildings, have stimulated Significantly exploration into the connected subject of products science. The very first fullerene was learned in 1985 by Sir Harold W. Kroto of the uk and by Richard E. Smalley and Robert File. Curl Jr., of the United States. Using a laser to vaporize graphite rods in an environment of helium fuel, these chemists as well as their assistants attained cagelike molecules made up of sixty carbon atoms (C60) joined by one and double bonds to form a hollow sphere with 12 pentagonal and twenty hexagonal faces—a style that resembles a soccer, or soccer ball.
