(PhysOrg.com) -- With its complete lack of atoms, a vacuum is often considered to be the best known insulator. For this reason, vacuums are regularly used to reduce heat transfer, such as in the lining of a thermos to keep ...
Vanderbilt mechanical engineering professors Deyu Li and Josh Caldwell are part of a team of researchers who have discovered a new heat dissipation channel using phonon polaritons that could have extensive implications for ...
