The NISE Net runs a series of online brown-bag conversations focused on helping partners share their work and learn from others in the Network. The aim of the online brown-bag conversations is to increase the number of professional development opportunities available to our partners, create more channels for Network partners to learn from each other directly, and create ways for partners to follow-up on ideas or efforts that emerge at in-person meetings.
The Science Behind NanoDays 2014 - Part 2
March 18th, 2014
10 - 11 am PST / 1 - 2 pm EST
Presenters: Lizzie Hager-Barnard of the Lawrence Hall of Science (UC Berkeley)
Are you interested in learning more about the science behind the NanoDays activities? Do you want to know more about how the NanoDays activities are related to cutting-edge research? Then please join us for an exciting presentation and discussion.
This brown-bag will focus on the applications and scientific background behind the following NanoDays 2014 kit activities:
Please note that this brown-bag is not a tutorial on the Nanodays kit (for information about the 2014 NanoDays kit, check out the What's Coming in Your NanoDays Kit brown-bag).
This is second of two brown-bags focused on the science behind NanoDays kit activities. The two brown-bags will focus on different topics, you are welcome to participate in one or both. Click here for The Science Behind NanoDays 2014 - Part 1.
You can download a PDF copy of the PowerPoint here.
Links and Other Resources:
Lizzie compiled a number of other resources based on questions from the brown-bag.
What kinds of materials are piezoelectric? Here are examples of piezoelectric materials:
- PZT (lead zirconium titanate)
- Rochelle salt
- More examples
- Does the degree of wetting depend on the circumference of a tube? (In other words, does the degree to which the liquid moves up in the walls, shown in Step 1 of Slide #6, depend on the radius?) I looked into this and I think the answer is no, it does not depend on the radius.
The details of wetting are pretty complicated, but if you’re interested in learning more this Wikipedia article seems pretty good: https://en.wikipedia.org/wiki/Wetting
The presentation includes many links, for both the images and relevant articles. Here’s a list of the most useful links:
- Gyroscopes for cameras
- Concussion sensors
- Harvesting energy from roads (cool animation!)
Other energy harvesting examples:
In the presentation, we suggested some complementary NanoDays activities. Here they are with their links:
- Gravity (related to Capillary Action)
- Smart Materials (related to Piezoelectric Effect)
