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 7: Diffraction Experiment with Simulation
Utilizing the difrfaction slides and laser pointers address the following questions.
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.
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.
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.

You may not be able to match the simulation perfectly to your measurements, but you certainly can make a judgement on a size range of the lines.
Blog Post 6: Good Nano Websites
Develop a list of at least 10 good Nano websites. Get two types, one of a general nature, and one that is focused on your interests.

Blog Post 5: Wave Interference Simulation Activities
Blog Post 5
1. Measure the wavelength of two drops of different amplitude, leave frequency constant.
2. Measure the wavelength of two drops with different frequency, leave amplitude constant.
3. Explain your results for Question 1 and 2.
4. Introduce a second faucet for the next set of questions.
- measure the wavelength of the two drips, in cm
- then measure distances from each drip(red dots) to the 6 constructive interference points (yellow dots) and report these values, cm
- explain the observation you have on the distance comparisons to the constructive interference points to the wavelength of the water wave.
