To minimize the propagation of the effects of an abrupt change in temperature, an insulating material is required with a low thermal diffusivity. This property is proportional to the thermal ...

Thermal diffusivity data for garnet schist, leucogranite and welded rhyolitic ash-flow tuff were acquired at temperatures of up to 1,260 K using laser flash analysis, which isolates the phonon ...

A groundbreaking thermal diffusivity microscope captures anisotropic heat flow in materials, enabling next-gen electronics, solar tech, and safer devices.
