Blog Post 8: Applications

Find 10 nano-applications of interest to you. Post a brief description and a link for more info. For each application, explain the "nano" part based on the descriptions of what makes nano special from the nano.gov website: http://www.nano.gov/nanotech-101/special



1. Fabric: Nano-dry
Quantem Effect
 http://www.nanotex.com/technologies/aquapel.html
Aquapel™ is the next generation in water repellency performance. Aquapel modifies fabric at the molecular level by permanently attaching hydrophobic ‘whiskers’ to individual fibers that elevate liquids, causing them to bead and roll right off the fabric surface. It features a hydrocarbon polymer which is both more ecologically friendly and economically smart. The result is excellent performance-liquid repellency that’s breathable, durable and fast drying- while remaining both fluorocarbon free and PFOA free.
  • Repels the elements
  • Resists spills
  • Maintains breathability
  • Eco-friendly technologys

2. Washing machine
Quantum Effect
http://en.wikipedia.org/wiki/Silver_Nano
Samsung home appliances, such as refrigerators or air conditioners, have a silver nano coating on their inner surfaces for an overall anti-bacterial and anti-fungal effect. As air circulates, the coated surfaces contact with the silver ions which can resist any airborne bacteria, which in turn suppress the respiration of bacteria, adversely affects bacteria's cellular metabolism and inhibits cell growth.[2][3]
Samsung says the silver nano technology sterilizes over 650 types of bacteria and that "Samsung WM1245A Washing Machine releases over 400 billion silver ions which penetrate deeply into fabrics of any kind and create a coat of sterilizing protection for a maximum of 99.99% disinfection and an added antibacterial effect of up to 30 days after washing".[4]
According to Paul Lipscomb, Product Manager, White Goods, Samsung Australia: "The Silver Wash system means that it's no longer necessary to soak clothes in additives or wash at extremely high temperatures in order to sanitise them. This combined with Samsung front loading washing machine's industry leading water efficiency ratings of up to 5A, creates a major saving on the long term cost of running the washing machine."[5]

3. Nano Pro Technology (NPT) in tires
Quantum / Surface Area
http://autos.aol.com/article/high-tech-tires/
With NPT we've been able to insert polymers that attach the to carbon black molecules and actually cause them to space themselves somewhat homogeneously. They're not touching each other, so you get a much cooler running temperature, which results in a significant reduction in rolling resistance. It also improves the traction."

4. Nanofiltration
Surface Area
nanosense.org/.../finefilters/nanofiltration/FF_NanofiltrationSlides.ppt
Environmental scientists and engineers are creating nanomembranes to filter contaminants from water cheaply and effectively.
Removes toxic or unwanted bivalent ions (ions with 2 or more charges), such asLeadIronNickelMercury (II)
Millions of people have no clean water to drink. Nano-clay and nano-fibres are being used to create cheap, effective water filters for developing countries.   
5. 3-D tape in televisions


5. quantum dot display
Quantum effect
http://en.wikipedia.org/wiki/Quantum_dot_display
 is a type of display technology used in flat panel displays as an electronic visual display. Quantum dots (QD) or semiconductor nanocrystals are a form of light emitting technology and consist of nano-scale crystals that can provide an alternative for applications such as display technology. This display technology differs from cathode ray tubes (CRTs), liquid crystal displays (LCDs), but it is similar to organic light-emitting diode (OLED) displays, in that light is supplied on demand, which enables new, more efficient displays, which is enabling mobile devices with longer battery lives.


6. medicine
Art of Biology
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
Nano-technology has produced better ways of delivering vital drugs to the right place in your body - but not in the shape of a tiny submarine! Nano-cages trap the drug molecules and then carry them to where they are meant to go.


7. Protective Armour
Surface Area
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
 A new type of carbon fibre, developed at the University of Cambridge, could be woven into super-strong body armour for the military and law enforcement.


8. Renewable Energy
Quantum Effect
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html

9. Smart Dust
Art of Biology
http://www.teach-ict.com/technology_explained/nano_technology/nano_technology.html
Engineers have recently made a radio component the size of a virus, so maybe 'smart dust' will become a reality where smart particles are spread over a battle field to report back to base. Or the particles are placed in your body to report back on your health.

10. Computers

Slide Simulation

http://phet.colorado.edu/en/simulation/wave-interference
  • Distance of wavelengths dots are dependent on the distance of the lens from wall.  (our  measurements are from 1,250mm away from wall)
  • Distance of dots are not dependent on distance of laser.
  • Dots are bigger and brighter (more intense) at the center and fade as they travel away from the center.
(Quad II) = A vertical line of dots spaced...
Green=10 mm apart
Red = 14 mm apart
Pattern printed on the slide? 2 slit
Distance between slits on slide: 1392.28nm

(Quad I) = A vertical line of dots spaced...
Green =  7mm apart.
Red = 9mm apart
Pattern printed on the slide? 2 slits
Distance between slits on slide: 7mm/







(Quad IV) =A horizontal line of dots spaced...
Green =  7mm apart.
Red = 9mm apart
Pattern printed on the slide? 2 slits
Distance between slits on slide: 7mm

(Quad III) = A horizontal line of dots spaced...
Green= 10mm apart. 
Red = 14mm apart.
Pattern printed on the slide? 2 slits
Distance between slits on slide: 1392.28nm

slits seperation: closer = dots spread out.
slits seperation: further apart = dots closer together.

1. What is the 4 patterns printed on the slides? Somehow draw and post this pattern on your blog, and explain how you arrived at this pattern.

a & c produce the horizontal of dots.  b & d produce the vertical dots.
We experimented on the wave simulater and found a similiar pattern to ours.

2. Determine the distance between the line patterns on the slides, and how thick the lines may be based on your changing of the simulator to duplicate the pattern you measured.
Distance betwen the line patterns on the slide:  smaller slit width = more dots
Thickness of lines:   smaller slit seperation = less dots

Due to the limitations of the simulation tool, we were unable give you an accurate picture of the simulation.  Our ratio in real life was 125%. (x=1250mm,Y=10mm)  The biggest I could represent on the simulator was 7%.  Math calculations tell us that the slit width is 22nm (x=174035 nm, Y=1392.28 nm)  theta = .458356468 degrees 

3. Setup the light wave simulator to simulate the patterns on the 35 mm slides. Grab a picture of these simulations and post them for each of your patterns.




























4. Which light can measure smaller things, red light or green light? Post an image of the simulator demonstrating this.
The green light can measure smaller things b/c it has shorter wavelengths. (like blue-ray= smaller burns marks for more laser)

Blog Post 5: Wave Interference Simulation Activities

Blog Post 5

1. Measure the wavelength of two drops of different amplitude, leave frequency constant.
Amplitude = 1.34 cm Wavelength = 5.12 cm
Amplitude = .18 cm Wavelength = 5.12 cm

2. Measure the wavelength of two drops with different frequency, leave amplitude constant.
Frequency = 1.36cm apart Wavelength = 1.26 cm
Frequency = 1.98cm apart Wavelength = 1.98 cm

3. Explain your results for Question 1 and 2.
+/- Amplitude = same wavelength
+ Frequency = Shorter Wavelength / - Frequency = Longer Wavelength

4. Introduce a second faucet for the next set of questions.








- measure the wavelength of the two drips, in cm

x= 2.33cm
y= 2.33 cm

- then measure distances from each drip to the 6 constructive interference points and report these values, cm
x to 1= 2.96cm          y to 1= 2.96cm
x to 2= 2.96cm          y to 2 = 5.17cm
x to 3= 5.17cm          y to 3 = 2.96cm
x to 4= 7.28cm          y to 4 = 7.28cm
x to 5= 5.17cm          y to 5 = 5.17cm
x to 6= 7.28cm          y to 6 = 5.17cm



- explain the observation you have on the distance comparisons to the constructive interference points to the wavelength of the water wave.

Creates a PATTERN (of distance): 
 x/y to 1 & 5 = same distance  ,  x/y to 2 & 3 = same-opposite  ,    x/y to  4 & 6 = same-opposite
= Waves meet up at the same pattern.  Constructive (full waves) and Destructive (half waves) patterns. The dots meet at full wavelengths + their multiples.
