Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling ...

Mountain permafrost is warming and thawing worldwide due to climate change, with ground temperature being a key control of ...

In this article, we discuss the laser flash diffusivity method’s working principle, applications, its advantages over other methods, and finally its limitations and research directed towards ...

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 ...

Thermal diffusivity is a measure of the speed at which heat propagates in a medium by conduction when the temperature varies with time. It is a thermophysical property whose value is directly ...

SLF researcher Samuel Weber explains his new method for determining how quickly heat penetrates deep into permafrost. This will help to detect changes in mountain regions at an early stage and make it ...
