WebGiven the limited permeation depth and non-uniform permeation observed at tape strips 6-18 when applied as a topical imiquimod cream, a permeation enhancement strategy … 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. Permeation is modeled by … See more 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 … See more Abbé Jean-Antoine Nollet (physicist, 1700–1770) Nollet tried to seal wine containers with a pig's bladder and … See more The permeation of films and membranes can be measured with any gas or liquid.
