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 ...

(Nanowerk News) 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 ...

In a recent experiment, to be published in Nature on Nov. 9, Dr. Matthias Meschke and professor Jukka Pekola, together with Dr. Wiebke Guichard, a coworker from French CNRS, investigated heat exchange ...

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, ...

Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms and ...

For the first time, scientists have measured the heat transferred by the quantum effervescence of empty space. Two tiny, vibrating membranes reached the same temperature despite being separated by a ...

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 ...

Heat transfer is the physical act of thermal energy being exchanged between two systems by dissipating heat. Temperature and the flow of heat are the basic principles of heat transfer. The amount of ...
