"Nanotechnology, nanotubes and molecules as tinker toys"

Sean Washburn , University of North Carolina at Chapel Hill
[Host: Joseph Poon]
Nanotechnology holds many promises for the future and many (possibly insurmountable) challenges before the promises can be implemented. Carbon nanotubes with their superb mechanical and electrical properties are a canonical example of both of these aspects. The possibility of assembling them into designed forms as new materials or or into nanometer mechanical and electrical devices might lead to improved strengths, speeds, etc. Some elementary experiments indicate that while the promise is still great, the barriers to implementing such nano-devices are still ahead of us. The methods of the experiments already have shown that many academic disciplines and new techniques will be involved in invoking the new improvements. Some examples of such efforts will be reviewed.
