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 ...

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 ...

New research from the Department of Energy's Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about ...

Modern portable and wearable electronic devices increasingly integrate high-performance components and wireless communication technologies. While this integration enhances functionality, it also ...

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.

Scientists have discovered that applying an electric field to certain ceramics can dramatically redirect how heat moves through them.

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 ...

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, ...
