Nanocomp Technologies, Inc., a Concord, N.H. — based maker of carbon nanotube materials, said last this week the Air Force selected the company as prime contractor for the second phase of a larger program intended to find a substitute for the nickel - based conductors currently used for electrostatic discharge (ESD) and EMI shielding.

Studying these electrostatic forces required researchers to devise an improved optical approach and to innovate to overcome hurdles, such as the presence of water and mineral - structure effects that impeded precise measurements.

Why It Matters: Generally hidden from our perception without advanced scientific instrumentation, electrostatic forces attract fine bits of particulates that cement onto surfaces, creating costly problems.

Such force would be of similar strength to the electrostatic force at separations around 1 nm, remain strong at distances up to the size of toxin molecules (several nanometers), and persist even beyond.

As Titan experiences one - seventh of the gravity we experience on Earth, the electrostatic force in any structures composed of these particles — like dunes or sand castles — overcomes the force of gravity, and they refuse to slump for very long periods.
