Scotland,The following cases of diffusion-evaporation for a solid sphere with radial transfer and constant diffusivity, are of interest. The initial concentration within the sphere is considered uniform:

The Law of the Excluded Middle: A DigressionTesting of rubber materials involves exposure to various types of environmental factors: temperature, which plays a part in all environment tests, moisture, steam, liquids and gases.

The Law of the Excluded Middle: A DigressionThe process of drying of plasticised PVC appears to be strange at first, but it can be explained by the formation of steep gradients of concentration which play a important role when the diffusivity is concentration dependent.

Thin Plane Sheet,Various cases of one-dimensional diffusion in a solid bounded by two parallel planes, with evaporation on the surfaces, are considered. The plane sheet is so thin that all the liquid evaporates through the plane surfaces and a negligible amount through the edges, and the diffusivity . is constant.
