"Nanotechnology" isa broad term that includes aspects of materials science, mesoscopicphysics, organicandinorganicchemistry, na- electronics, atmosphericchemistry, airpollution, and other?elds. The technology is very muchincurrent focus-at the beginning of the Third Millennium-and raises hopes for environmentally benign, resource-lean manufacturing of products of manykinds. One precursor to present-day nanotechnology used porous coatings, comprised of "ultra?ne" particles withdimensions inthe nanometer range, for absorption of thermal radiation on thermocouples, bolometers, and the like....
