- What's a question you asked today or to one of Dr. Belfort's team, or our tissue engineers? (Tissue engineering is not on quiz, but questions to them count.)
- Be able to explain (with a few exceptions that you don't have to explain) do colored substances have high electrical resistance?
- Does everything with temperature give off light?
- How does angular momentum play a role in understanding that the old model that "electrons orbit nuclei" cannot be true?
- Why might he Titanic be less likely to sink if it hit the same iceberg at the same speed in the same way, if it was built out of today's steel?
- Know something about the following classes of materials: steel, super alloys, titanium alloys, shape memory alloys, biodegradable metals - which materials are best used where and why?
- What are the advantages of lithium polymer batteries over traditional lithium ion batteries?
- Why are Ti, Al, and Mg used in laptops and air crafts?
- Why is Ti more expensive than Al?
- Useful terms, ideas, concepts:
- ev (electron volt)
- actuate
- phase (as used in context of metals; not 'solid liquid and gas'.)
- resistance
- black body radiation
- band gap
- conduction band compared to valence band
- photo electric effect
- emission spectra
- role of temperature in material ages (e.g. bronze age)
- contributions of Schrodinger
- marble in tube analogy for conduction and valence bands
- insulator, semi-conductor, and conductor
- diffraction (resolution benefits of light, xray, and electron)
- Connections to other guests - Dr. Koratkar (batteries), Dr. Palermo and Ullal (materials), Mr. Colwill (clean room)
