WebPermeation. In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity.

WebAug 13, 2024 · Vapor semi-impermeable: 1.0 perms or less and greater than 0.1 perm. Vapor semi-permeable: 10 perms or less and greater than 1.0 perm. Vapor permeable: greater than 10 perms. Materials with lower perm ratings are better at stopping the movement of water vapor. If the perm rating is low enough, the material is a vapor retarder. WebThe rationale for the correlation between intestinal permeability rate and the extent of metabolism appears to be based on the fact that high permeability rate compounds are reabsorbed from potential unchanged drug excretion routes in the body and thus can only be eliminated through metabolism.

WebJul 5, 2024 · The main advantages of Ni-Cu-Zn ferrites are their low sintering temperature T s, high resistivity, medium permeability, low loss, and good performance up to MHz frequencies [1,2,3,4].

The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence of a semipermeable membrane. Only molecules or ions with certain properties will be able to diffuse across such a membrane.
