Transcript of Nano Technology


Nanomedicine
Nanofibers
Where do you stop - treatment or enhancement?
Loss of humanity
2006 TGN1412 disaster
New field of science
Lack of research
Unknown long-term effects
Issues
Nanocomposites
- new, lighter, stronger materials mean more efficient transport (carbon fiber)
Phase change materials for thermal energy storage (windows, siding/insulation)
Control of heat/light flux into buildings
Block or store light/heat when hot, let in or release energy when cold
Energy Usage

Has potential to revolutionize every way we interact with energy, down to level of electron
Nanofabrication: “tiny machines”
->
new ways to capture, store, transfer
energy
Reduce consumption in usage
Increase efficiency in production
Nanotechnology in Energy
Nanobots & Drug Delivery
"Nanorobots will appear in clinical therapies in the 2020s"

by Kirk, Luke, Julia, and SeYeon

nan·o·tech·nol·o·gy
( )
noun:
the branch of technology that deals with dimensions and tolerances of less than 100 nanometers, esp. the manipulation of individual atoms and molecules.

Medicine:
Energy:
Consumer/Industry:
Carbon nanotubes
1000x
more conductive than copper (low-loss power lines)
Battery/supercapacitor improvements (membranes, electrodes)
Nanostorage of hydrogen (clathrates) for mass storage
Energy Storage/Distribution
Stronger, resilient, lighter materials for wind, steam, water turbines, etc.
Materials to sequester CO2 from power plants
Most gains to be made in solar energy
Thin, dye, polymer, paint, flexible solar cells.
Thermoelectric generation is promising

Energy Sources

Industry
Apparels:
clothing with a coating of nanoparticles that repels stains— Nano-Tex Corporation of Oakland, Calif.
Patent/Licensing:
revenues by licensing innovations to manufacturers of optical and electronic products - NanoGram Corporation in Milpitas, Calif.
Super Condoms, Molecule Printers, Strechable Gold, Plastic that Bleeds and Heals Itself, Electricity-Generating Viruses
REALLY?! THEY EXIST?
TU
in energy nanotechnology
Recieved ARPA-E funding recently (
up to $1.76 million!
)
Solar cell efficiency decreases when hot
Thermal energy can be used to produce electricity
Solar cells only use part of light bandwidth (band gap)
Gold nanoparticle fluid lets useable light through, absorbs other light in form of
heat
Solar cell then runs cooler and more efficiently, hot nanoparticle fluid used toproduce more electricity from steam turbine
Research started around 2000
Delicate but potentially revolutionary
Slowly emerging in countries
-Robert Freitas
Body absorbs protein-based drugs
2004, NYU chemists developed walking nanobot from DNA fragments
Use to trigger leukemia and lymphoma cell suicide
In Situ
, "nanofactories"
“There are 200 commercial products in cosmetics, apparel and sporting goods in which nanotechnology plays a role.”
“…by 2015 nanotechnology will play a crucial role in $1 trillion worth of products, which would require two million workers.”
-Lynn E. Foster


emerging technologies director for Greenberg Traurig law firm
-Mihail Roco
senior adviser for nanotechnology at the National Science Foundation
Nanobots
: nano-sized robots used to transport materials throughout the body
Historically costly and time-consuming
Growing carbon and lead nanofibers
Repairing brain and spinal cord injuries, hernias and fistulas
Thinnger, more flexible, easier in surgery, breaks down over time
Nanofibers:
fibers less than 100 nanometers in diameter, used for surgical textiles, implants, tissue engineering, artificial organ components
Trends
Higher Strength Composites
and advancements in Sustainability
Carbon Nanotube Pre-impregnated materials
High Conductivity
Stronger epoxy
Already proven success with the Juno Probe to Jupiter
Also aids in energy conservation techniques such as
Better fuel economy across the board
Production of more efficient renewable resource harvesting technologies
Production of high capacity supercapacitors
Higher quality energy storage units
Scalability of Production
Most complex aspect we face with the implementation of nanotechnology is making it affordable
Current logistics limit us to the use of either:
Expensive raw materials
Slow and complicated manufacturing processes
Commercialization
Prototype and even current market development have shown results in creating nanoscalable composites
Southwest Nanotechnologies is an example of a nanotube producing firm that is contributing to controlling the purity and structure of nanotechnologies, by controlling these aspects the costs associated with the economy of scale vastly decrease

NanoMedicine
Market ready and commercialized industries have already effected the treatment of cancers in humans and have shown results
Companies such as:
Nanospectra Biosciences
Siemens
Preferred Surgical Products L.L.C
Precision Therapeutics, Inc
Med BioGene Inc.
Promising developments have been made in the biosciences and patents for experimentation and development have already been established or are in the process right now
