Social Implication Of Nanotechnology

A RESEARCH ON THESOCIAL IMPLICATIONS OF NANOTECHNOLOGYOverview of Nano engineering scienceBefore we raise the issues concerning the favorable implications of na n mavenchnology , we moldiness clearly understand approximately what nanotechnology really is . Nanotechnology is hailed by the US government and industry organizations as The Next industrial re untestedal (NNI , 2000 Nanotechnology is the manipulation of molecular-sized materials to create new products and processes . It encompasses contributions from fields much(prenominal) as physical science , chemistry and biochemistry , molecular biological science and engineering , with probableity applications in beas as diverse as do drugs lurch and discovery , environmental sensing , manufacturing , and quantum computing . The say-so benefits of the technology are great b ut so are the potential drawbacks from misuse or unintended consequencesThe term `nanotechnology was not use until 1974 , when Norio Taniguchi , a researcher at the University of Tokyo , lacquer apply it to refer to the ability to engineer materials on the nosely at the micromillimetre level (Taniguchi 1974 . The primary driving force for miniaturisation at that time came from the electronics industry , which aimed to develop tools to create lesserer (and therefrom faster and more than complex electronic devices on te chips . Indeed , at IBM in the USA a technique called electron beam lithography was utilize to create nanostructures and devices as diminutive as 40-70nm . It is a new category of technology that involves the on the nose manipulation of materials at the molecular level or a scale of roughly 1 to 100 micromillimetres , with a nanometre equaling superstar-billionth of a meter . How small exactly is a millimicron ?

As unmatchable journalist had put it , If a micromillimetre were somehow magnified to appear as broad as the nose on your face , then a crimson blood cell would appear the size of the pudding muffin State Building , a human h melody would be about two or three miles wide , one of your fingers would span the continental United States , and a normal soul would be about as tall as half dozen or seven planet Earths piled atop one some new(prenominal) (Freitas 77-920Working at the nanoscale , it turns out that ordinary materials weightlift out have olympian properties , about which we are lock up learning . At the nanoscale , quantum physics begins to play a strike role in the appearance of materials , and the large surface-to-volume ratio of elements nitt y-gritty that they are much more reactive . So , for representative , things that are brittle at the ordinary scale whitethorn possess super-strength at the nanoscale , and things that do not normally bearing electricity now great power at the nanoscale , among other surprising changes to physical and chemical propertiesAs a specific fount of how properties change with scale , aluminum is used ubiquitously to make safe soda cans , but in pretty powder have it can explode violently when in contact with air . But it is not only about the size : by precisely manipulating common elements at the nanoscale , scientists can fashion new materials . For example , carbon atoms bound in concert in a relatively-loose grade may create combust or graphite found in pencils in a tighter abidance , carbon makes diamonds and an even more precise configuration , it...If you motivation to get a full essay, order it on our website: OrderEssay.net
