Nanoparticles by https://padlet.com/mglockcroc/2mydbgywu8zv hi en-us 2017-08-27 23:59:04 UTC 2017-08-30 07:39:22 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Doubleheart.png The history of nanopooticles mglockcroc https://padlet.com/mglockcroc/2mydbgywu8zv/wish/183007948 In 1889, two British inventors were granted exclusive rights by the government to produce 'hair-like carbon filaments' from methane. In the 60's and the 70's groups all over the world, and even some in NZ, produced and identified the tubes. Nanotubes were then rediscovered in 1991 by Sumio Iijima. It has been discovered that nanotubes can be produced in large amounts. They are really expensive so if you wanna buy a gram then sorry mate but that'll be a hundred buckarooes ]]> 2017-08-28 00:01:38 UTC https://padlet.com/mglockcroc/2mydbgywu8zv/wish/183007948 why did the can crusher quit his job? jasper_lin https://padlet.com/mglockcroc/2mydbgywu8zv/wish/183008684 because it was soda pressing]]> 2017-08-28 00:09:11 UTC https://padlet.com/mglockcroc/2mydbgywu8zv/wish/183008684 what do you call a fake noodle? jasper_lin https://padlet.com/mglockcroc/2mydbgywu8zv/wish/183008884 2017-08-28 00:11:40 UTC https://padlet.com/mglockcroc/2mydbgywu8zv/wish/183008884 The properties of nanoparticles mglockcroc https://padlet.com/mglockcroc/2mydbgywu8zv/wish/183063752 Nanoparticles are unique because of their large surface area.
Examples of the physical properties of nanoparticles are:

  • Color – Nanoparticles of yellow gold and gray silicon are red in color
  • Gold nanoparticles melt at much lower temperatures (~300 °C for 2.5 nm size) than the gold slabs (1064 °C)
  • Absorption of solar radiation in photovoltaic cells is much higher in nanoparticles than it is in thin films of continuous sheets of bulk material - since the particles are smaller, they absorb greater amount of solar radiation
  • They exhibit unusual strength, and unique electrical properties. They are also extremely efficient conductors of heat.

-  They can be used to get rid of heat from tiny computer chips. 
- Their strength and flexibility in its small size, allows the nanotubes to be used in controlling structures at a nanoscale. 

  • sports equipment: nanoparticles are added to materials to make them stronger whilst often being lighter. They have been used in tennis rackets, golf clubs and shoes
  • clothing: silver nanoparticles have been added to socks. This stops them from absorbing the smell of sweaty feet as the nanoparticles have antibacterial properties
  • healthcare: nanoparticles are used in sunscreens. They offer protection and can be rubbed in so there are no white marks.

  • Despite all the research, scientists still don't understand exactly how they work
  • Extremely small, so are difficult to work with
  • Currently, the process is relatively expensive to produce the nanotubes
  • Would be expensive to implement this new technology in and replace the older technology in all the places that we could
  • At the rate our technology has been becoming obsolete, it may be a gamble to bet on this technology
