"MATERIALS: Self-isolating nanoparticles eyed for storage"

Supercomputer simulations running in the trillions of operations per second provide a virtual test tube for the nanoparticles to be used in a new generation of magnetic media for tomorrow's hard-disk drives. To prove that point, researchers at the Pittsburgh Supercomputing Center and Oak Ridge National Laboratory recently modeled a promising nanoparticle material exhibiting a hitherto hidden capability that the researchers say could enable densities of 1 terabit/square inch.
