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.

Fouling Mechanisms in Y-shaped Carbon Nanotubes
out of 5 stars
04 Apr 2007 | | Contributor(s):: Jason, SeongJun Heo, Susan Sinnott
In the modern pharmaceutical and chemical industries, solutions of extremely high purity are needed. Current filtration methods are reaching the limits of their abilities, so new filters must be developed. One possible filter is a Y-shaped carbon nanotube (Y-tube). By changing the sizes of the...
From Research to Learning in Chemistry through Visualization and Computation
17 May 2007 | | Contributor(s):: Eric Jakobsson
Modern chemistry research and high school chemistry education are separated by institutional and geographical boundaries. As such, much of secondary chemistry education is still based on the periodic table instead of the computational methods that drive current chemistry research. In this talk,...
