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 ...

After a decade of work, Issam Mudawar will soon see the results of the largest phase change experiment ever conducted in space. WEST LAFAYETTE, Ind. — People who design spacecraft must prioritize two ...

In most conventional semiconductors, thermal conductivity decreases as temperature rises because heat-carrying lattice vibrations—called phonons—scatter more frequently.

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 ...

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, ...

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.

Thermal Conduction is a “hot” topic! Dr. Rob and the Crew explore how thermal energy is transferred and conserved in different environments. STEM Challenge: Making Thermal Oobleck Curious About ...
