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.

Crystal Viewer Demonstration: Various Crystal Systems
12 Jun 2009 | | Contributor(s):: Gerhard Klimeck, Benjamin P Haley
This video shows the use of the Crystal Viewer Tool to visualize several crystal systems, including Si, GaAs, C60 Buckyball, and a carbon nanotube. Crystal systems are rotated in 3D, zoomed in and out, and the lattice style changes from sticks and balls to lines to spheres.
Nanotribology, Nanomechanics and Materials Characterization Studies
08 Jun 2009 | | Contributor(s):: Bharat Bhushan
Fundamental nanotribological studies provide insight to molecular origins of interfacial phenomena including adhesion, friction, wear and lubrication. Friction and wear of lightly loaded micro/nano components are highly dependent on the surface interactions (few atomic layers). Nanotribological...
