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.
