Metamaterials enable control of heat transfer at nanoscale, potentially transforming energy and electronics by Carnegie Mellon University edited by Gaby Clark, reviewed by Robert Egan Editors' notes ...

The radiative heat exchange between two bodies at different temperatures can be successfully described by the well-known Stefan-Boltzmann law when they are separated by a macroscopic vacuum gap, such ...

Yellow waves show propagating atomic vibrations observed at ORNL’s Spallation Neutron Source. In a smart, switchable ceramic, an electric field aligns charges so vibrations along white field lines ...

Scientists used electric fields to extend heat-carrying vibrations in ceramics, revealing a promising path toward solid-state devices that actively manage thermal energy flow. (Nanowerk News) New ...

This paper combines the leaf vein structure with fins which are the essential parts of heat exchangers to enhance the overall heat transfer performance, without significantly increasing thermal ...
