The dimensionality play a major role in determining the characteristic of nanomaterials including physical, chemical and biological characteristics. . Nanotechnology, also shortened to nanotech, is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes. But something as small as an atom is impossible to see with the naked eye. Nanotechnology is the term given to those areas of science and engineering where phenomena that take place at dimensions in the nanometre scale are utilised in the design, characterisation, production and application of materials, structures, devices and systems. I have noted previously the rather imaginative approach the publication IBT takes to nanotechnology, and I know that I probably should just ignore them. The first use of the distinguishing concepts of nanotechnology was "There's Plenty of Room at the Bottom", a talk given by physicist Richard Feynman in 1959.K. [82] A newspaper article reports that workers in a paint factory developed serious lung disease and nanoparticles were found in their lungs. Berkeley, California is currently the only city in the United States to regulate nanotechnology;[73] Cambridge, Massachusetts in 2008 considered enacting a similar law,[74] but ultimately rejected it. [23], Two main approaches are used in nanotechnology. The field of nanotechnology has been on the defensive for reasonable causes, such as the safety of workers that handle certain nanomaterials. Survey: K-12, higher Ed grammar disconnect. Nanotechnology, or nanotech for short, deals with matter at a level that most of us find hard to imagine, since it involves objects with dimensions of 100 billionths of a meter (1/800th of the thickness of a human hair) or less.
