6. NANO10
• High school nanoscience course
• Lecture and hands-on laboratories
• Small mini demonstrations
• Larger one and two day labs
• Rigorous laboratory science (for HS)
• Students are AP level (mostly seniors)
7. NANO10 Lab Activities
• Photolithography – could be done in
NANO Camp – but chemicals need prep
• Solar PV fabrication – tricky but fun!
• Supercapacitors – working the bugs out
• Nanoparticles – nanogold / nanosilver
• Ferrofluid synthesis – tricky and messy
• Modeling tools – needs time and guidance
9. Solar Cell
Fabrication
Dye sensitized photocells are
made from frozen raspberry
juice applied to titanium dioxide
on glass. One side of the cell is
coated with graphite from a
pencil, and potassium iodide is
used as a donor of electrons in
the photoconduction circuit.
Students make measurements of
voltage and current in the cell.
The lab takes about 100 minutes,
so either needs a long lab, or two
one hour periods. This activity
looks harder than it is, and is
actually quite approachable.
10. Surface Area to Volume
Students use play-doh to create
small objects which are used to
make measurements of surface
area to volume ratios. Students
then plot those ratios verses the
size of the object ( millimeters)
and observe the size range. In
the nanoparticle synthesis lab,
we do calculations of surface
atoms to interior atoms, and
again plot that ratio as a function
of particle size. Students then
observe that as nanoparticles
get very small, say 5 to 10 to
20nm , the number of surface
atoms proportionally grows.

13. NANO Camp
• Four day hands-on exercises
• 20+ Self-guided learning activities
• Targeted to high school (science) students
• Possible extension to HS teachers
• The idea is fun learning / experience
• NANO Camp can also be a NANO Club
14. NANO Camp 2014/15
• Modeling
• Crystal structure
• Size and scale
• Forces
• Digital microscopes
• AFM/SEM
• Fuel cell demo
• Nitinol
• Nanoparticles
• Surfaces
• Solar PV
• Lithography
20 plus exercises
Bonus: 3D printing of MEMS and Stanford Nanocenter Walking Tour
16. Graphene
Modeling
The graphene modeling
was among the more
favorite activities in the
camp. Students worked in
teams to prepare
fullerenes, carbon
nanotubes, and other (yet
to be invented) carbon
structures. The hands on
modeling was far more
effective than PowerPoint,
and even the computer
modeling. This activity also
allowed students to work in
teams, with each group
working on a nanostructure.
22. Socialization of Science
• Mentoring of students
• Influence (social) networks
• Four levels of college students
• Faculty researchers
• Small business innovators
24. Mentoring of Students
• Influence (social)
science networks
• Multiple levels of
college students
• Faculty and NASA
UCSC researchers
• Small business
innovators / PBL
Students form groups around projects and work with each other in teams
25. Mentor Training
Foothill College students Anh Nguyen and Yessica Torres (now at
EAG labs) participate in materials research and microscopy
training at NASA-ASL using a Transmission Electron Microscope
(TEM).
26. Gold Nanoparticle TEM
NASA-ASL intern David Skiver
prepared gold nanoparticles
using sodium citrate reduction
of auric chloride. Particles are
produced in a dark solution
and suspended in a TEM grid.
This particle was imaged at 1
million X using a Hitachi HR
9500 TEM. Students can see
individual gold atoms in the
particle, which is ~ 15 nm in
diameter. The group is now
developing an approach to
nanosilver particles using silver
nitrate and sodium citrate.
27. AFM Image of Nano Islands
Mn on GaN 2u x 2u Amorphous region 5u x 5u
AFM images from PNI Nano-R AFM using Close Contact Mode
28. Real Science – Real Learning
Nothing is as fun as doing it yourself – Robert Cormia using XPS Spectrometer
30. Summary
• NANO10 – Nanoscience
• NANO Camp => NANO experience
• Mixture of labs and lectures
• Lab experience can be complex
• Integrated SLOs / NANO big ideas
• NANO can be academic or a club
• Hands-on activities are essential
