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 ...

Earth's core acts like a storage heater, with heat released during crystallization of the inner core that buffers the slow cooling of the planet as it radiates its heat to space. The most obvious ...

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.

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 ...

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 ...

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 ...

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 ...

You may have heard that some people are brave enough to walk across hot coals, but would you ever attempt to carry coals, or a whole fire, in your hands, for miles and miles? Cultures from around the ...
