(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 ...

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 ...

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 ...

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.

Using four-photon scattering, Purdue University researchers found that graphene's thermal qualities might not be as groundbreaking as first believed. Image Credit: Kateryna Kon/Shutterstock.com ...

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 ...

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 ...
