Textiles
Electronics
Food
Sporting equipment
….and more!
Enter information as best fits your class

3. Materials Nano-coated fibers Guitar strings Sunscreen
Water & stain resistant
Antibacterial
Guitar strings
Feels like non-coated
Coated to improve strength
Sunscreen
Better UV protection
Water resistant
Transparent!
Nano-coated fibers: Nanoscale coatings can be applied to fabrics to affect some properties but without changing the feel, texture or flexibility of the fabric. Silver ions have antibacterial properties. Silver nanoparticles embedded into fabrics/insoles can release ions, killing bacteria and helping to eliminate odors.

4. Sporting Goods Composites can make materials lighter and stronger
Carbon (nanotubes and graphene)
SiO2 nanoparticles
Carbon nanotubes incorporated into adhesive allows paddle to be stiffer without increasing weight
Silica nanoparticles fill voids in carbon fibrr composites increasing durability/stability – tennis raquet

5. Transportation Composites can make materials lighter and stronger
Carbon fiber nano-composite hull
Lighter materials for electric vehicles
Nanocomposite is stiffer and reduces occurrence of cracks in hull.
Velozzi supercar has 80% body made of carbon composites, makes cars both lighter and safer

6. Electronics - Computers
Computing Hardware
Processors – 14 nm
Moore’s Law
Moore’s law = The number of transistors on an integrated circuit (processor chip) will double every year. 14 nm = distance between features on chip
Fabricated using advanced lithography

7. Electronics - Displays
Organic - LEDs
Organic molecules emit light = brighter
Flexible
Roll to roll processing
Traditional LEDs are light by a white backlight and color is filtered by dye molecules. OLEDS emit light of different colors.
Organic LEDs are like polymers and can be flexible if printed on a flexible conductive substrate
Roll to roll processing = cheaper devices once optimized

8. Solar Cells Emerging Technologies: Thin Film Solar Cells: Organic
CIGS, CdTe, Amorphous Si
Emerging Technologies:
Organic
Dye Sensitized Solar Cell
Quantum Dot
Amorphous Si

9. Dye Sensitized Solar Cells
Increased surface area / volume ratio of TiO2 nanocrystals allows enough dye to attach to generate electrons to power device. DSSC are not as efficient but nicer to look at!

10. Medicine Targeted and traceable drug delivery Enhanced imaging
Sensitive detection
Excess sugar displaces a dye molecule in the lens, making it change color; also UW/Microsoft
and

11. Lab on a Chip Also called microfluidics Point of care diagnostics
High throughput screening
Device shown is for isolating cells to help speed up the process of genetic analysis. Its function can replace something like a FACS (fluorescence activated cell sorter) which is a large, expensive instrument.

12. Food SiO2 of TiO2 coatings Fat Clusters Packaging
Undetectable by taste or small
Increases shelf life
Fat Clusters
Increased surface area to volume
Improved taste (surface area)
Less fat (volume)
Packaging
Smart packaging: spoilage sensors
Plastic bottles with improved barrier properties from nanoclay
3D printing allows microcircuits in milk cap that can sense food spoilage
