Blog Post 16: Dr. Matt Ray Presentation

Yesterday we had a very informative talk on nanoparticles termed colloids. Dr. Ray showed some great images and videos of nanoparticles in solutions.

1. Describe your observation of the common liquid in which he started his talk.

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.

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.

Blog Post 14: Final Exam/Project

The final invention project is Due Dec 19, Monday and to be presented to the class during the final exam period which is at 10:00 am in room 150.

An electronic file needs to be submitted of the presentation and the poster to Dr. Schultz. Please submit these in the dropbox on the D2L site.

Blog Post 13: Nano and Proteins

1. Post a brief description (and link) to a general overview of MALDI.

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.

4. Research and post a cool nano-application that involves proteins.

A great resource for protein is at the Protein Data Bank at: http://www.pdb.org/pdb/home/home.do

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.

Blog Post 11: Invention Team/Timeline

Post the names of the individuals working on your invention team. Describe the activities that each person is engaged with and list the timeline for your activities to complete your invention project. The invention complete project is due Dec 19. Each team needs to create a 24" x 26" poster that describes the invention. Topics/questions to address on the poster are:

what is the issue/opportunity you are trying to address? Describe the background and current efforts to address this issue/opportunity

describe your invention that utilizes nanotechnology, describe what makes the invention based on nanotechnology

describe the materials and processing that would be needed to make the invention

address any safety/environmental concerns

address costs for developing and producing

address any regulations that may need to be addressed

address the consumer acceptance of this nano-invention.
