Controlling material structure at nanoscale makes better thermal insulator

Abstract:
Heat may be essential for life, but in some cases - such as protecting the space shuttle or improving the efficiency of a jet engine - materials with low thermal conductivities are needed to prevent passage of too much heat. As reported in the Feb. 13 issue of the journal Science, researchers have created a better thermal insulator by controlling material structure at the nanoscale. "We explored ways to control thermal properties in materials by introducing structure on nanometer length scales," said David Cahill, a professor of materials science and engineering and a Willett Faculty Scholar at the University of Illinois at Urbana-Champaign.
