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 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 ...

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, ...

The thermoelectric effect can turn waste heat into electrical energy. To make use of it, special materials with unusual properties are required. A remarkable effect has now been demonstrated, which ...

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 ...

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 ...

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.
