Definition the systematic manipulation of matter on the length scale 1-100 nm to produce useful new engineered structures, materials, or devices. History – R. Feynman, 1959, “There’s plenty of room at the bottom” -Kroto, Smalley, Curl, 1985, synthesis of Fullerene, C60 -SumioIijima, 1991, carbon nanotubesynthesis Nanotechnology today – 1600 companies, 700 industrial products -world-wide investment of 4.8 billion $ / yr The U.S. National Nanotechnology Initiative (NNI) – first passed in 2001 -now ~ 1 billion $ / yr -optimistic status report: May 2005 -four phases envisioned (now in phase 1) The Nanotechnology Movement ©Hyperion catalysis website about 1/1000 width of human hair Nanotechnology is the development of…. Nanoparticles -buckminsterfullerene -metallic nanoparticles (gold, silver, iron) -glass/ceramic nanoparticles (titania, silica) -quantum dots (semiconductor nanoparticles) Nanotubes, nanofibers -carbon nanotubes -nanofibers (carbon, polymer, ceramic) -nanowires (metallic, semiconducting) Nanoplatelets Nanoplateletgraphite, clay, silica, hydroxyapatite Nanostructured surfaces Nanostructured solids and their application as components for next-generation technologies, including: batteries, fuel cells, sunscreens, cosmetics, structural materials, implants, drug delivery vehicles, catalysts, sorbents, and much more.
