A NIMS research team has developed a technique that enables the nanoscale observation of heat propagation paths and behavior within material specimens. This was achieved using a scanning transmission ...

Thermal diffusion, often termed thermophoresis, describes the migration of species in a fluid under a temperature gradient. In multicomponent mixtures this gives rise to the Soret effect, whereby ...

Concrete’s thermal behaviour is governed primarily by its conductivity, diffusivity and heat capacity, all of which determine the rate at which heat is stored and transferred through walls, floors and ...
