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

In most conventional semiconductors, thermal conductivity decreases as temperature rises because heat-carrying lattice vibrations—called phonons—scatter more frequently.

Scientists at Oak Ridge National Laboratory have found that applying an electric field to a specialized ceramic can nearly ...

In experiments, MIT engineers demonstrate a fiber, made from a common polymer material, changes its ability to handle heat as it is stretched. Most materials have an inherent capacity to handle heat.

A study shows how high-thermal dielectrics outperform FR-4 for bulk heat spreading, with surface-mount thermal bridges ...

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, ...
