1. Goals for Today: Nano-In-The-News Finish Introduction
Begin NanoScience Discussion
Assignments

2. What is responsible for the current nano revolution?
The tools
AFM, STM, FESEM
How about x-ray & TEM?

3. Nano in the News! Local Dr. Frank Underdown
Keweenaw Nanoscience Center
Lake Linden, MI
(visiting speaker in March…)

5. What is Nanotechnology?
The application of nanostructures into useful nanoscale devices.
Many biological inspirations!

6. Nanoscale science and engineering
here refer to the fundamental understanding and resulting technological advances arising from the exploitation of new physical, chemical and biological properties of systems that are intermediate in size, between isolated atoms and molecules and bulk materials, where the transitional properties between the two limits can be controlled.
-Mike Roco (NSF) 2001

7. Nanotechnology Heirarchy
Bulk Chemistry/Materials
(Chemistry & Physics accomplish the self-assembly)
Manufacturing (e.g. Intel)
directed assembly
Nanomachines
Self Replicators (life?)
Increasing Complexity
(information, design)

8. Transistor density on a chip doubles every ~18 months.
Moore’s 1st Law
