Nanotechnology and the Community - Nils Petersen

  1. 1. 1 000 m 1 Yottameter =1024 m 1 000 000 m 1 000 000 000 m = 109 m1 000 000 000 000 000 000 m = 1018 m = 1 Exameter
  2. 2. 0.001 m 0.000 000 001 m = 10-9 m = 1 nanometer = 1 nm 0.000 001 m
  3. 3. Department of ChemistryFaculty of Science Nanotechnology and the Community A primer on nanotechnology
  4. 4. The intended message:Nanotechnology will be Pervasive – it will affect all sectors of society Persistent – it will be with us forever Powerful – it will be an economic driver globallyFor communities to take advantage of this emergingtechnology framework will require Planning – and that is what the project is all about Pervasive-Persistent-Powerful
  5. 5. Mt Everest = 8 km on earth Equivalent to 8x10-3 cm or 8 micrometers on grapefruit Earth is 100 times smoother than a grapefruit Nanoparticles are seldom spherical and therefore very rough Seldom all the same size1.2 nm gold nanoparticle 12 cm grapefruit 12 000 km Earth 1:100 000 000 1:100 000 000 How do we think about a nanometer?
  6. 6. 100 nm cell membrane 1 cm pad of paper 1 000 m elevation 1:100 000 1:100 000 How do we think about a nanometer?
  7. 7. Surface Effects:Material (Intensive) Properties Change: Source: K.J. Klabunde, 2001 and M.Meyyappan (2006) Nanotechnology – what are we talking about?
  8. 8. Clay – Oil – Water mix too well Surface properties lead to an emulsion that will not separate easily – heat is needed Oil – Green Solid – Red Water – Brown Small particles will not settle – tailing pondshttp://www.nrcan.gc.ca/es/etb/cwrc/English/AST/Teams/Emulsions/emulsions_e.html The problem with Oil Sands is tiny solids (clays) in the oil
  9. 9. Quantum Mechanics tells us: EDiscrete Energy Levels (Quanta)(think floors of a building)Energy Levels Depend on Size(Tall & narrow building or E ELow & wide building) ΔE1 > ΔE2Determines:Color of materials - wavelength R R λ1 < λ2 Energy levels depend on size
  10. 10. Quantum Dots range in size from 1 to 10 nm or more. The change in size  different energy levels for the electrons  different wavelengths for absorption and emission of light  different colours Particles are from Si, Ge or CdSe. Blue is small – Red is largeApplications range from diagnosis (tracers) to solar energy (absorbers) 1 nm www.evidenttech.com 6 nm Quantum Dots are illustrate quantum confinement
  11. 11. A simple application of plasmon resonanceThe association of the antibody with the antigencauses an aggregation of the gold nanoparticlesleading to a shift in the plasmon absorption Sold in very large numbers as(red to blue) >99% reliable pregnancy test A neat optical example
  12. 12. We have now learned to:visualize design and control at the nanoscale So why is nanotechnology important now?
  13. 13. MoviesOriginal_slices.avi .... as acquired 8hrs of dataInner_view_x_rot.avi … reconstructed 3D rendering of voids.Processing developed by Martin Kupsta (NINT). Visualize and control
  14. 14. Visualize Control (cutting) Design Control (assembly) Visualize-Design-Control
  15. 15. Visualize Control (etching) Design Control (assembly) immersion in reagents remove polymer 100 nm Visualize-Design-Control – Nanotechnology will be Persistent
