What people who study nanotechnology are interested in? 4. <...> What is the distinguishing concept in nanotechnology? 5. <...> History of Nanotechnology Richard Feynman was the first scientist to suggest that devices and materials could someday be fabricated to atomic specifications. <...> The first distinguishing concept in nanotechnology was “Bottom”, a talk 4 given by the physicist Richard Feynman in December, 1959. <...> In the 1980s the basic idea of this definition was explored by Dr. K. Eric Drexler, who promoted the technological significance of nano-scale phenomena and devices. <...> Nanotechnology is a group of emerging technologies in which the structure of matter is controlled at the nanometer scale, the scale of small numbers of atoms, to produce novel materials and devices that have useful and unique properties. <...> Some of these technologies impose only limited control of structure at the nanometer scale, but they are already in use, producing useful products. <...> A nanometer is one billionth of a meter. <...> The definition, most frequently used by government and industry, involves structures, devices, and systems having novel properties and functions due to the arrangement of their atoms on the 1 to 100 nanometer scale. <...> Richard Feynman was the first scientist to suggest that devices and materials could someday be fabricated to atomic specifications. 2. <...> The first … concept in nanotechnology was “Bottom”, a talk given by the physicist Richard Feynman in December, 1959. 3. <...> Concerns have been raised regarding potential health and environmental effects of the passive nanostructures termed “nanoparticles”. <...> To build a personal nanofactory (PN), you need to start with a working fabricator, a nanoscale device that can combine individual molecules into useful shapes. <...> A fabricator could build a very small nanofactory, which then could build another one twice as big, and so on. <...> Products made by a PN will be assembled from nanoblocks, which will be fabricated within the nanofactory. <...> What do you know about carbon nanotubes? 2. <...> Sea anemones inspire nanotechnology fabrication of tough nano-containers The addition of carbon nanotubes (CNTs), both single-walled, to various polymer matrices has produced significant improvements in strength and stiffness. <...> As is the case so often, and covered quite extensively at Nanowerk <...>
