Nanotechnology Presentation Language And Culture

  1. 1. Nanotechnology Concept- a nanometer is 10-9 (a billionth) of a meter   The prefix nano is Greek for dwarf . 
  2. 2. Definitions <ul><li>Nanotechnology is the art and science of manipulating matter at the nanoscale to create unique materials and products. </li></ul><ul><li>Nanotechnology is the study and use of structures between 1 nanometer and 100 nanometers in size. </li></ul><ul><li>Nanotechnology involves the manipulation of structures at the atomic and molecular scale. This gives substances new properties with huge economic potential. </li></ul>
  3. 3. <ul><li>How many nanometers is… </li></ul><ul><li>Approximately </li></ul><ul><li>The width of a hair 100,000nm </li></ul><ul><li>The width of a red blood cell 10,000nm </li></ul><ul><li>The length of a typical bacterium 1,000nm </li></ul><ul><li>The width of a dust particle 800nm </li></ul><ul><li>The width of a computer chip wire 100nm </li></ul><ul><li>The width across the helix of DNA 2nm </li></ul><ul><li>The width of a carbon atom 1nm </li></ul>
  4. 5. Applications
  5. 6. Nanomedicine <ul><li>The biological and medical research communities have exploited the unique properties of nanomaterials for various applications: contrast agents for cell imaging and therapeutics for treating cancer. </li></ul><ul><li>The integration of nanomaterials with biology has led to the development of diagnostic devices, physical therapy applications, and drug delivery vehicles. </li></ul>
  6. 7. Chemistry and environment <ul><li>Chemical catalysis and filtration techniques are two prominent examples where nanotechnology already plays a role. </li></ul><ul><li>A strong influence of nanochemistry on waste-water treatment, air purification and energy storage devices is to be expected </li></ul>
  7. 8. Energy <ul><li>The most advanced nanotechnology projects related to energy are: storage, conversion, manufacturing improvements by reducing materials and process rates, energy saving and enhanced renewable energy sources. </li></ul>
  8. 9. Information and communication <ul><li>Nanotechnology has already been introduced silently. The critical length scale of integrated circuits is already at the nanoscale (50 nm and below) regarding the gate length of transistors in CPUs or DRAM devices. </li></ul>
  9. 10. Heavy industry <ul><li>Aerospace - Lighter and stronger materials will be of immense use to aircraft manufacturers, leading to increased performance </li></ul><ul><li>Construction </li></ul><ul><li>Nanotechnology has the potential to make construction faster, cheaper, safer, and more varied. Nanotechnology construction can allow for the creation of structures from advanced homes to massive skyscrapers much more quickly and at much lower cost. </li></ul>
  10. 11. Consumer goods <ul><li>Foods - Research is being performed to apply nanotechnology to the detection of chemical and biological substances for sensing biochemical changes in foods </li></ul><ul><li>Optics </li></ul><ul><li>Nano-optics could allow for an increase in precision of pupil repair and other types of laser eye surgery. </li></ul>
  11. 12. Nanopatches join fight against swine flu. Australia <ul><li>At University of Queensland a team is applying nanopatch technology to potentially solve the problems associated with vaccinating millions. </li></ul><ul><li>Professor Kendall said this research used new nanopatch technology which does away with the needle and syringe and stimulated a potent immune response with a reduced dose. </li></ul>
  12. 13. Sources <ul><li>http://en.wikipedia.org/wiki/List_of_nanotechnology_applications </li></ul><ul><li>http:// www.youtube.com / watch?v = 5jqQxuVncmc video </li></ul><ul><li>http://www.nbtc.cornell.edu/ (Nanobiotechnology center-Cornwell University) </li></ul><ul><li>ww.rcentre.utm.my/files/nanotech-edit.jpg </li></ul><ul><li>http://www.uq.edu.au/news/index.html?article=18854 University of Queensland </li></ul>
