100 amps of electricity crackle in a vacuum chamber, creating a
spark that transforms carbon vapor into tiny structures. Depending
on the conditions, these structures can be shaped like little,
60-atom soccer balls, or like rolled-up tubes of atoms, arranged
in a chicken-wire pattern, with rounded ends. These tiny, carbon
nanotubes, discovered by Sumio Iijima at NEC labs in 1991, have
amazing properties. They are 100 times stronger than steel, but
weigh only one-sixth as much. They are incredibly resilient
under physical stress; even when kinked to a 120-degree angle,
they will bounce back to their original form, undamaged. And
they can carry electrical current at levels that would vaporize
ordinary copper wires.

Putting the Electron’s Spin to Work
14 Apr 2011 | | Contributor(s):: Daniel Ralph
I will discuss recent progress in experimental techniques to control the orientations of nanoscale magnetic moments and electron spins, and to use these new means of control for applications. One powerful new capability arises from the fact that thin magnetic layers can act as filters for spins.
Tutorial 2: A Bottom-Up View of Heat Transfer in Nanomaterials
23 Mar 2011 | | Contributor(s):: Timothy S Fisher
This lecture provides a theoretical development of the transport of thermal energy by conduction in nanomaterials. The physical nature of energy transport by two carriers—electrons and phonons--will be explored from basic principles using a common Landauer framework. Issues including the quantum...
