Social Implication Of Nanotechnology

A RESEARCH ON THESOCIAL IMPLICATIONS OF NANOTECHNOLOGYOverview of Nano leading scienceBefore we raise the issues concerning the fond implications of nanotechnology , we moldiness clearly understand intimately what nanotechnology really is . Nanotechnology is hailed by the US government and industry organizations as The Next industrial revolution (NNI , 2000 Nanotechnology is the manipulation of molecular(a)- size of itd materials to earn bleak products and processes . It encompasses contri simplyions from fields such as natural philosophy , chemistry and biochemistry , molecular biota and engineering , with authorisation applications in areas as diverse as drug obstetrical delivery and discovery , environmental spotting , manufacturing , and quantum computing . The potential benefits of the technology are great but so are the potential drawbacks from misuse or unmotivated consequencesThe term `nanotechnology was not employ until 1974 , when Norio Taniguchi , a researcher at the University of Tokyo , Japan use it to refer to the ability to engineer materials meticulously at the nanometer level (Taniguchi 1974 . The primary drive force for miniaturisation at that time came from the electronics industry , which aimed to let on tools to create clearer (and because faster and more than complex electronic devices on atomic number 14 chips . Indeed , at IBM in the USA a technique called electron beam lithography was lend matchlessself to create nanostructures and devices as little(a) as 40-70nm . It is a new category of technology that involves the precise manipulation of materials at the molecular level or a scale of roughly 1 to 100 nanometers , with a nanometer equaling wizard-billionth of a meter . How small exactly is a nanometer ?

As one journalist had put it , If a nanometer were somehow magnified to push through as prospicient as the nose on your face , then(prenominal) a red blood cell would appear the size of the empire State Building , a human hair would be about two or three miles all-inclusive , one of your fingers would span the continental United States , and a ruler someone would be about as tall as sextette or seven planet Earths piled atop one other (Freitas 77-920Working at the nanoscale , it turns out that ordinary materials kitty fill phenomenal properties , about which we are still learning . At the nanoscale , quantum physics begins to play a key role in the air of materials , and the large surface-to-volume ratio of elements means that they are much(prenominal) more reactive . So , for instance , things that are brickly at the ordinary scale may possess super-strength at the nanoscale , and things that do not normally conduct electricity straight off energy at the nanoscale , among other surprising changes to physical and chemical substance propertiesAs a specific example of how properties change with scale , atomic number 13 is used ubiquitously to make harmless soda cans , but in delightful powder form it can explode violently when in contact with air . But it is not single about the size : by precisely manipulating common elements at the nanoscale , scientists can fashion new materials . For example , carbon atoms ring together in a relatively-loose strain may create blacken or graphite found in pencils in a tighter configuration , carbon makes diamonds and an even more precise configuration , it...If you want to get a full essay, hostelry it on our website: BestEssayCheap.com
