nanotechnology in electronics
Nanotechnology in Electronics
  • Very close to being in actual consumer products
  • Can increase the power and speed of devices by several times
current process
Current Process
  • Lithography – top down method of writing structures on a surface with a probe
  • Lithography can only go so far
  • Memory and processor speeds are nearing their current theoretical maximums
  • As we near the theoretical limits, traditional silicon chips become less reliable due to size issues
  • Square arrays over hexagonal
computers
Computers
  • The new process of building computers will be with a bottom up process
  • Block co-polymer lithography
  • 3-4 times smaller chips
  • 2-3 times the power
  • No start-up time
faster processors
Faster Processors
  • etching can only go so far
  • 10-15% better drive current gives better performance and less leakage
  • Transistors from carbon nanotubes that have doubled the electrical current
new memory types
New Memory Types
  • Nanodots
  • Nano sized dots of nickle
  • Terabyte storage capacity
  • Can be packed much closer as they act as independent units
bio nanotechnology
Bio-Nanotechnology
  • Nano chips inside of cells
  • Huge medical potential
  • Spiral structure found most durable
  • By 2020, 2500 transistors could fit on a cell
cell phones
Cell Phones
  • Many the same aspects of computers
  • Smaller transistors give higher frequencies = better reception
  • Longer battery life
  • Phone companies would need less towers
cameras
Cameras
  • Possibilities of no flash
  • SMPD image sensors can sense more light and IR wave lengths
  • 12 mega pixel cell phone cameras due to quantum dots
  • Quantum dots are color specific and absorb and transfer light better than silicon receptors
maybe not everyday to you
Maybe not Everyday to You
  • The U.S. military uses electronics on an everyday basis.
  • Night vision and thermal imagers are used by soldiers, pilots, and UAVs
  • Gives the US a major advantage
night vision
Night Vision
  • The core of night vision is the microchannel plate(MCP)
  • Electrons pass through thousands of microchannels which multiply the electrons
  • New microfilm that is 10,000 times thinner than a human hair
thermal detectors
Thermal Detectors
  • New development with carbon nanotubes
  • Microbolometer detectors
  • New technology has lowered micron pitch down to 17 from previous numbers of 50-100.
wrap up
Wrap-up
  • Still a lot of development occurring in this field
  • However the first of the next generation of chips, processors, computers, etc should be coming into the market within the next couple of years
  • Greatly increases the current capabilities in all aspects

Ability to conduct electricity

spill and stain resistance
Spill and Stain Resistance

Treats the material with chemicals that change the clothing on the molecular level

Allows for spills to bead, rather than soak into fabrics

water resistance
Water Resistance

Material made from coating polyester fibers with small silicone filaments

Layer of silicone nanofilaments is highly hydrophobic

water resistance32
Water Resistance

Combination of hydrophobic surface chemistry and the nanoparticle structure leads to this “super-hydrophobic” effect

water resistance33
Water Resistance

Lotus leaves use a similar combination of water repelling materials and tiny nanostructures

The silicone nanostructures also trap a layer of air in-between them creating a permanent air layer known as a plastron

odor resistance
Odor Resistance

Material that can trap odors and release them in the washing machine

Achieved by treating the fabric with nanoparticles

conducting electricity
Conducting Electricity

Pairs of textile fibers covered with zinc oxide nanowires can generate electrical current using the piezoelectric effect.

general comments
General Comments
  • Overall, there was very little negative feedback on the presentation.
  • Thanks to all for the constructive criticism.
  • We feel we have greatly improved our presentation skills from the first presentation to this one.
speaker performance
Speaker Performance
  • Several notes were made about inadequate use of the microphone and laser pointer. We will do our best to ensure that we make full use of the items available to present topics clearly.
  • We felt that the presentation was a solid performance and that only small improvements could have been made.
presentation
Presentation
  • Several comments were made about the good use of relevant pictures and humor. We tried our best to implement more of these aspects into our presentation.
  • We were missing some citing information and will do our best to not make this mistake in the future.

positive notes
Positive Notes
  • Fantastic topics chosen
    • Lots of details and specifics about nanotechnology in computers and cars
    • Really captured the audience with relevant, and important, data critical to devices used everyday
  • Slides had good format
    • Easy to read
    • Lots of helpful graphics
  • A lot was presented
    • The need for further inquiry of certain topics was almost unnecessary due to thorough presentation
  • Showed a variety of uses from small microprocessors, to travel and clothing, to an overall global economic scale.
  • The topics were broken up into clear, succinct, subjects that were easy to follow, and all important to everyday use.
opportunities for improvement
Opportunities for Improvement
  • Group 1 thinks that the only area for improvement would be to practice working together as group presenters more
    • However, the overall presentation, transitions, data, and topics presented were highly professional
  • Danielle is a bit quiet when speaking. Perhaps better use of the microphone would have helped
the bad
The bad
  • Sources of images not cited
  • Some font size was too small
  • Almost 3 presentations in one file; disjointed feeling
  • Did they really only use 4 sources for the whole thing?
  • Not based on any specific paper(s)
the good
The good
  • Professional layout
  • Color Scheme was effective and not distracting
  • Relevant figures
  • Excellent ability to see how electronics and automobile applications are relevant to daily life; not easy to see for clothing

positives
Positives
  • The variety of topics discussed made the presentation interesting and showed the wide applicability of nanotechnology in common uses.
  • Speaking was very good throughout the presentation.
  • Presentation contained plenty of pictures, which helped keep the audience entertained with the presentation.
areas for improvement
Areas for Improvement
  • Almost none of the images had cited sources.
    • Cite your sources!
  • Although a lot of information was presented on what nanotechnology can do in our daily lives, not much was said about how it achieves these goals.
    • Add more information regarding mechanisms of each application.
    • This would have made each application seem more real (i.e. currently being done) and less like the dreams of some futurist.

presentation review58
Presentation Review
  • The graphical effects on the car picture with the scratched surface were good and helped to show the scratches to the audience.
  • Overall, the team did a great job, and the ice cream was very good. 

review61
Review
  • All the presenters spoke clearly and confidently
    • No filler words
    • Great transitions
    • Excellent tone/poise/dress code
  • Improvements
    • The laser pointer should have been used more
    • All the pictures and text should have been properly cited (we recognize that each section was sited, but more is required)
    • The sources at the end of the presentation should not simply be website pages
  • Overall, great presentation – it was a great change from all the traditional nano-scale experiments
  • The ice cream made the entire presentation much more enjoyable- thanks!
