schliz writes to mention that a team of quantum physicists have demonstrated how to significantly reduce the effects of "stiction," or the tendency for two very small, very close objects to stick together as a result of Casimir force. "'The Casimir force might be one of the many reasons that very small, movable components in micromechanical devices sometimes stick together,' said Ho Bun Chan, a assistant professor of physics at the University of Florida who is researching the Casimir force. 'The Casimir effect increases rapidly as the separation between components decreases. It becomes significant when the separation is reduced to below about 400 nm,' he told iTnews."
