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.

People who design spacecraft must prioritize two factors: reducing weight and managing extreme temperatures. A new experiment designed by Purdue University engineers addresses both problems. The Flow ...

The quantum of thermal conductance, G Q = πk B 2 T/6ℏ, provides the fundamental upper limit for heat conduction through a single channel 8,9. Here, T is the temperature, k B denotes the Boltzmann ...

Combining state-of-the-art realistic atomistic modelling and experiments, the paper describes how thermal conductivity of ultrathin silicon membranes is controlled to large extent by the structure and ...

Technical ceramics are used in many applications where traditional materials such as steel or plastic are ineffective or unsuitable. For many of these applications, extreme hardness, wear resistance, ...
