The design and necessity of corrosion-resisting nanocarbon nanocomposites have been investigated for chopping-edge aerospace programs. In a while, in 1991, Drexler, Peterson and Pergamit revealed An additional guide entitled “Unbounding the Future: the Nanotechnology Revolution” wherein they make use of the terms “nanobots” or “assemblers” for nano processes in drugs https://www.directivepublications.org/journal-of-applied-nanoscience/
