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 ...

Yellow waves show propagating atomic vibrations observed at ORNL's Spallation Neutron Source. In a smart, switchable ceramic, an electric field aligns ...

(Nanowerk Spotlight) Being able to fabricate materials that allow a reversible tuning of their electrical and thermal properties near room temperature has many potential applications such as seasonal ...

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 ...

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, ...
