Investigating thermal properties of gas-filled planetary regoliths using a thermal probe [PDF]
We introduce a general purpose penetrator, fitted with a heater, for measuring temperature and thermal diffusivity. Due to its simplicity of deployment and operation the penetrator is well suited for remote deployment by spacecraft into a planetary ...

Effect of electron thermal carriers on thermal diffusivity of metals [PDF]
A photoflash method of thermal diffusivity measurement was used to determine the value of thermal diffusivity of a sandwiched aluminum layer in a three-layer sample when the sample is simultaneously subjected to both thermal and electric field gradients.
