Taming tiny, unruly waves for nano optics
Nanoscale devices present a unique challenge to any optical technology -- there's just not enough room for light to travel in a straight line. As light waves are pressed through surfaces only a few nanometers apart (smaller than their wavelength), they become unstable and difficult to predict. But Georgia Tech researchers have discovered a method of predicting the behavior of light on the nanoscale during radiation heat transfer, opening the door to the design of a spectrum of new nanodevices and technologies.

Models present new view of nanoscale friction
Friction is a force that affects any application where moving parts come into contact; the more surface contact there is, the stronger the force.

With their high surface-to-volume ratio, nanomaterials are especially susceptible to the forces of friction. (2009-02-25)
