Overview


Nanotechnology in Electronics


Nanotechnology in Automobiles


Nanotechnology in Clothing

Nanotechnology in Electronics


Very close to being
in actual consumer
products


Can increase the
power and speed
of devices by
several times


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


The new process of
building computers
will be with a bottom
up process

Faster Processors

so far

-
15% better
drive current gives
better performance
and less leakage


Transistors from
carbon nanotubes
that have doubled
the electrical
current


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


Nano chips inside of
cells


Huge medical
potential


Spiral structure found
most durable


By 2020, 2500
transistors could fit on
a cell




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


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


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


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


New development with carbon
nanotubes


Microbolometer detectors


New technology has lowered micron
pitch down to 17 from previous
numbers of 50
-
100.


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

Summary of Nanotechnology
Applications to Modern Automobiles

Nanotechnology in Clothing


Resistant to spills and stains


Water resistant


Odor resistant


Ability to conduct electricity

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


Material made from coating polyester
fibers with small silicone filaments


Layer of silicone nanofilaments is
highly hydrophobic


Causes water to bead



Water Resistance


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

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


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


Achieved by treating the fabric with
nanoparticles

Conducting Electricity


Pairs of textile fibers covered with
zinc oxide
nanowires

can generate
electrical current using the
piezoelectric effect.

Conducting Electricity

Conducting Electricity


Nanogenerators create electricity
through movement


Allows a person to power their own
electrical devices while moving

Conducting Electricity


Current
nanogenerators

do not
produce enough power


After further research, estimates say
one sq meter of material could
produce 80
mW

of power

Conclusion


Research is proving that the
possibilities are limitless

Presentation)

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


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


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.

Food


Everyone loves ICE CREAM!!!!!!!!!!!!!!


Presentation:

Nanotechnology in the Daily Life

By Group 4


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.


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

S2 review of

S4
Nanotechnology in Daily Life

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


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


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


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 Review


The speakers all did well. They spoke clearly
and loudly.


Adding humor to the slides was a good way to
keep the attention of the audience.


The topics that they chose to discuss were
relevant to the audience. This also helped to
make their presentation interesting.


The graphics that were shown complimented
the material.

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.

Review


We enjoyed the macro
-
scale approach of the
presentation; the impact of nanotechnology in our daily
lives was interesting


High quality slides


looked like a lot of work was put into making them


Clear and easy to read


Great text to picture ratio


It was a good to split the topic into electronics,
automobiles, and clothing.


They all have a large impact on our lives


There were many pictures that helped convey the
concepts throughout the presentation that made
everything easier to understand

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
