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 ...

For the first time, scientists have succeeded in precisely controlling temperature-dependent thermal conductivity with the help of polymer materials. These advanced functional materials were initially ...

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 ...

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 ...

The discovery of a novel mechanism by a team of researchers that further suppresses thermal conductivity in thermoelectric materials will aid in the development of new standards for the manufacture of ...

Synthetic quartz may help reduce the carbon footprint of industries that produce things like glass, steel, and cement. In recent experiments, Federal University of Technology, Zurich, engineer ...

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 ...

The UL Firefighter Safety Research Institute (FSRI) has released a new online training course, “Introduction to Heat Transfer and Fire Measurement” based on the “Full-Scale Experiments to Study the ...
