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 ...
A physics informed machine learning model predicts thermal conductivity from infrared images in milliseconds, enabling fast, ...

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 ...
(Nanowerk Spotlight) Being able to fabricate materials that allow a reversible tuning of their electrical and thermal properties near room temperature has many potential applications such as seasonal ...
Physicists in Finland have shown that it is possible to conduct heat over macroscopic distances at close to the maximum efficiency permitted by quantum mechanics. By directing photons along a ...
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, ...
Engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat -- an ability normally associated with metals. In experiments, they found the ...
The particles of liquids are further apart than solids. This means that most liquids are poor conductors of heat because the frequency of collisions is reduced. The particles of gases are even further ...
A lot of power means a lot of heat. NASA’s future missions to explore the Moon and Mars will require enormous amounts of electrical power and hardware to support astronauts and drive new technologies.
