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.

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
