Sts 4

• Nanometre or nanometer


  A unit of length in the metric system, equal to one billionth of a metre
• Technology


  The use of scientific knowledge for practical purposes or applications, whether in industry or in our everyday lives
• Nanoscience


  • The study of structures and molecules on the scales of nanometers ranging between 1 and 100 nm
  • The study of phenomena and manipulation of materials at atomic, molecular, and macromolecular scales where properties differ significantly from those at a larger scale
• Nanotechnology


  The branch of science and engineering devoted to designing, producing, and using structures, devices, and systems by manipulating atoms and molecules at nanoscale
• The term "nano-technology" was first used by Norio Taniguchi


  1974
• Nanoscale "assembler"


  A device that would be able to build a copy of itself and of other items of arbitrary complexity with atomic control
• How nanotechnology works


  The manipulation of matter on a near-atomic scale to produce new structures, materials and devices
• Application in energy


  • Clean, less expensive sources enabled by novel nanomaterials and processes
  • Companies are currently developing batteries using nanomaterials
  • Making the production of fuels from normal raw materials more efficient
• Application in medicine


  • Nanomaterials can be applied to gradually release drugs in biological fluids in order to favor a better absorption in the intestine or other tissues
• Nanodevices


  • Nanoparticles that are created for the purpose of interacting with cells and tissues and carrying out very specific tasks
  • The most famous nanodevices are the imaging tools
• Nanoelectronics


  • Mobile phone castings are good examples
  • The goal is to process, send, and keep information
