Presentation Transcript

  1. Bio-Medical Energy: Fuel Cell Drug Delivery (nano-particles) Pharmaceutical MACRO ~10o m Industries Bio Energy Electronics MICRO [mm] ~10-6 m Nano Science & Technology Fundamental Sciences NANO [nm] Chemistry Biology ~10-9 m Physics Electronics-Information: Storage NanoScience & NanoTechnology Motivation • Industries Selected Areas: • Energy  Fuel Cells, Solar Cells, Lubrication • Electronics  Storage, Transistor (Gates) • Pharmaceutical  Drug Delivery • Bio-Medical  Implants

  2. NanoScience & NanoTechnology Motivation: Nanocellular Growth Tendon Cell Growth Growth Inhibited on Nanopatterned Surfaces Structured surface -> directed growth Nanoarray in fused silica Nano- patterned -> growth inhibited Unstructured surface -> growth randomly C.D.W. Wilkonson et al., Mat. Sci. and Eng. C, 19 (2002) 263

  3. NanoScience & NanoTechnology Motivation: Carbon Nano-Foam The creation of a molecular structure involves “atom-to-atom” “assembly” under appropriate physical conditions and rate. • Laser ablation is one possible avenue to create man-made materials. E.g., from graphite: • Fullerenes and Carbon Nanotubes • Amorphous Carbon (Films) • Carbon Nano-Foams Granular low density nanofoam: TEM image shows the free-standing fractal structure of the carbon foam. The foam consist of a network of interconnected carbon clusters of ~ 6nm in size A.V. Rode et al., Appl. Phys. A 70, (2000) 135
