Yesterday we had a very informative talk on nanoparticles termed colloids. Dr. Ray showed some great images and videos of nanoparticles in solutions.
I just saw this blog!
1. Describe your observation of the common liquid in which he started his talk.
I was 5 minutes late for class and must have missed this part. Although I thought what He presented to the class was one of the most interesting pieces and applications of nano.
2. Dr. Ray explain two ways in which keep small particles from sticking to themselves and aggregating in to large masses. He explained that the surface area of these particles is important to maintain to feel the benefits of the nanosize. Explain those two methods that he described
he talked about the large football huddle or "fight" huddle.
He talked about the two lines coming togethar and meeting and then being forced apart. I didn't understand the surface area part being important for not sticking together... but I do remember the object having the surface area the size of a football field.

Blog Post 15: Dr. Asthana Presentation
Dr. Rajiv Asthana presented to our class his work on nano and micro materials. There were two topics that were of particular interest. For this post I would like for you to explore the topics/questions below:
1. What are grains and grain boundaries in a material? I suggest you focus on metals. Explain how material properties are affected by the size of these grains.
2. How does one engineer or process materials to reduce the grain size? In particular, I would like for you to explore and then explain how single crystal silicon is produced for the solar industry.
Dr. Schultz,
I was gone on my career development conference this week. Is there anything I can do to make up this blog?
Thanks,
Billie

Blog Post 13: Nano and Proteins Guest Speaker
1.. Post a brief description (and link) to a general overview of MALDI.
A great resource for protein is at the Protein Data Bank at: http://www.pdb.org/pdb/home/home.do
primary can make structures...like a spring
Trtiary Structure- alpha beta structures ... we are able to make models.Dalton = unit of mass. Think molecular mass- molecular mass of a given molecule of mass = 20 kDa (20,000 Dalton)
m/z = mass to charge ratio... MALDI requires ionization.
MALDI-TOF Mass Spectometry... put dry plate in a vaccuum to observe. need matrix (yellow stuff on sample plate) ionizes assisted laser absorbtion.
KE = 1/2 mv62
Time of Flight (TOF)
Bradykinen(1080.210) and Neurotensin (1673.932) = biological structures that do stuff. 5 parts per million can tell exact identification. (Accurate Mass)
MALDI lets you visualize.
MALDi TOF-TOF = get peptide sequence information. very exciting biological studies like multiple sclorosis. Sample lake water... spin down the cells... put on plate... profile cynobacteria isolated from lakewater. Cool part is it takes minutes to get profile! Hospitals can use this with patients and analyzing there bacteria. Snake venim is another popular profiling use.
2. Post an image (3D) of the following proteins: microcystin LR, collagen, and pick another one of your favorite proteins.
3. Post the size of each of these proteins in nanometers.
microcystin LR = 2.496 nm
collagen = 5.364nm
hemoglobin = 4.124 nm
4. Research and post a cool nano-application that involves proteins.
Nanotechnology drives protein engineering, new approach to drug discovery | |
(Nanowerk News) Using a nanoscale spring built from a molecule of DNA, investigators from the University of California, Los Angeles, have taken a significant step toward a new approach to protein engineering. This new tack to modifying protein function, note the researchers, could lead to novel ways of killing cancer cells. |

Blog Post 12: Invention Background/References
Post 10 references to your invention project. Post a brief paragraph of the summary of each of your references. These references must be from the primary literature which can be accessed through the UW-Stout library. I suggest utilizing Web of Science and Science Citation Index.
Electroactive textile fibres and fabrics have been used in smart and interactive clothing for medical, military and sports applications. The improved surface properties of conductive textiles are required for their successful integration in all of the above mentioned applications. This paper presents the production of conductive poly(3,4-ethylenedioxythiophene) (PEDOT) coated viscose yarns in longer length, i.e. 5 m, and the surface modification of the coated yarns by treating with silicone solution. The structural properties of silicone coated conductive yarns were then investigated by Fourier transform infrared spectroscopy and thermogravimetric analysis. The effect of silicone coating on the mechanical, electrical and hydrophobic properties was also evaluated and then compared with the PEDOT coated viscose yarns without surface treatment. Results show that the mechanical and hydrophobic properties of conductive yarns were improved by surface modification with silicone without affecting their structural properties. The surface modified PEDOT coated yarns could be used as pressure and stretch sensors in health care applications.

2. Counterion Exchange to Achieve Reversibly Switchable Hydrophobicity and Oleophobicity on Fabrics | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Author(s): | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Source: Abstract: We describe a simple layer-by-layer (LbL) technology and counterion exchange procedure to tune the liquid wettability of commercially available cotton fabrics. A polyelectrolyte multilayer is deposited on the fabric surface by the LbL technology, and counterion exchange is used to control the surface composition and thereby to modulate the solid surface energy. The tunability of the solid surface energy, along with the inherent re-entrant texture of the cotton fabric, results in simultaneously switchable wettability between a nonwetting state and a fully wetted state for water and hexadecane. This switchable hydrophobicity and oleophobicity can be explained within a robustness factor, which is a quantitative criterion for the transition between the two states. The counterion exchange can be confirmed by X-ray photoelectron spectroscopy analysis.

describe the materials and processing that would be needed to make the invention nano:
•Fheet has three thin layers. The inner layer is a moisture wicking smartwool that is extremely soft and comfortable against your skin. An extremely thin middle layer of aerogel insulation, and a fashionable smartwool outer shell.
•An aerogel is an open-celled, mesoporous, solid foam that is composed of a network of interconnected nanostructures and that exhibits a porosity (non-solid volume) of no less than 50%.
•SmartSilver nanoscale additives can be integrated at the molecular level into natural and synthetic fibers and fabrics, coatings, foams and polymer applications to provide antimicrobial and anti-odor protection that lasts the expected life of the product.

address any safety/environmental concerns
FHeet are completely safe to the user and environment.
Due to the advanced nano technologies used to produce aerogel insulation, in its raw form aerogel insulation will release extremely fine dust called nano particles. That is why we must encapsulate the aerogel to utilize it in our garments. If the encapsulation is punctured, the aerogel nano-particles will "dust" through the hole and fabrics of the garment. This dust feels like the chalk dust you would rub off of a black board in a school room. It is harmless to the wearer, but the puncture must be fixed to prevent further damage to the panel.
With nanotechnology, less is really more. Small silver particles have a greater surface area available to interface with bacteria, thus increasing efficacy while conserving silver raw materials. Only a tiny amount of silver is needed to get a tremendous amount of benefit.
NanoHorizons’ silver additives are embedded in fibers, polymers and coatings. The minute amount of silver ions that these silver particles emit during normal use is the key to silver’s benefits in therapeutics, pathogen control, odor control, and materials preservation. In wastewater, these emitted silver ions are quickly deactivated by common substances—like chloride and sulfide—to form unreactive minerals.
