“nanotechnology”的概念、定义、翻译、参考文献-科学参考

nanotechnology

Physics

The development and use of devices that have a size of only a few nanometres. Research has been carried out into very small components, which depend on electronic effects and may involve movement of a countable number of electrons in their action. Such devices would act much faster than larger components. Considerable interest has been shown in the production of structures on a molecular level by suitable sequences of chemical reactions. It is also possible to manipulate individual atoms on surfaces. See also Nanophysics (Feature).

Chemistry

The development and use of devices that have a size of only a few nanometres. Research has been carried out into very small components, which depend on electronic effects and may involve movement of a countable number of electrons in their action. Such devices would act much faster than larger components. Considerable interest has been shown in the production of structures on a molecular level by suitable sequences of chemical reactions. It is also possible to manipulate individual atoms on surfaces using a variant of the atomic force microscope.

Chemical Engineering

The study of materials of the nanometre scale ranging from 1 to 100 nm. Nanotechnology involves the creation and/or manipulation of nanomaterials, either by scaling up from single groups of atoms, or by refining or reducing bulk materials.

Electronics and Electrical Engineering

The construction and handling of nanostructures. Nanotechnology was predicted in 1959 by physicist Richard Feynman, but did not get under way until the invention of scanning-tunnelling microscopy in 1981. Today a range of nanofabrication techniques exist, using very high-resolution microscopes, lithography, chemical synthesis, and various self-assembly techniques. See also nanoelectronics.
