Nanotech Nanotech Presentation Transcript

  • Nanotechnology Yesterday, Today and Tomorrow March 21, 2008
  • What Nanotechnology Is…
    • “ Nanotechnology is the engineering of functional systems at the molecular scale .”–
    • (What is Nanotechnology?)
    • “ To begin, "nano" is actually a prefix that comes from the Greek word for dwarf.”– (Cook)
    • 1/1,000,000,000 of a meter
    • is the size of a nanometer
    Think about the size of a nanometer for a second…
  •  
  • Nanotechnology Information…
    • Funding for Nanotechnology research has increased, as well as papers published
    • “ Interest in clean water research is flowing. And much of it is focused on nanotechnology, which many believe will be a major contributor to new industrial and public water purification systems.” – (NNI)
  • The History…
    • On December 29, 1959, Richard Feynman was the first scientist to suggest machines at an atomic level.
    Richard Feynman
  • The History…
    • Eric Drexler, in 1981, published the article, “Molecular engineering: An approach to the development of general capabilities for molecular manipulation” – (Kelty)
    • He also published his first book, Engines of Creation, in 1986
    • “ In 1988 he taught the first formal course on nanotechnology while a visiting scholar at Stanford University” – (IEEE)
    • Created term “Nanotechnology
    Eric Drexler
  • Current Uses…
    • “ Apollo makes real diamonds using nanotechnology.” – (Maney)
    • Sunscreens
    • Drugs
    • “ A study by Lux Research found that 3,800 nanotech patents have been issued so far, and 1,777 more are pending.” – (Maney)
  • Current Uses…
    • A plastic nanocomposite is being used for “step assists” in the GM Safari and Astro Vans
    • Nanocrystals have been shown to be from 100 % to 300% harder than the same materials in bulk form
    • Used in antibacterial socks
    • Toothpaste also contains nanotechnology
  • Future Uses…
      • “ Researchers also are working toward engineered nanomaterials for use as artificial tissues that will replace diseased kidneys and livers, and even repair nerve damage.” – (McCarter)
      • More questions than ideas at this point in the game
      • Nanotechnology is still a new discovery
  •  
  • What Now…
    • The possibilities are probably endless
    • Great caution needs to be taken when dealing with altering the human contents
    • Could have great results if handled properly
    • Need to keep an open mind
