Diffusionsmittel
Diffusionsmittel (diffusion medium) is a term used in German to describe any substance or phase that permits the diffusion of another substance. In diffusion processes, the diffusing species moves through the medium by random molecular motion, and the rate and extent of diffusion are governed primarily by Fick's laws, as well as by temperature, viscosity, and the size of the diffusing molecules.
Common examples of diffusion media include gases such as air, liquids such as water or organic solvents,
Applications range from basic teaching experiments, where dyes diffuse in agar plates to illustrate diffusion, to
Measurement and analysis often involve diffusion cells or other experimental setups, and rely on models based
