Fickiaanse
Fickiaanse is a term used in Dutch-language science to describe diffusion that follows the laws of Fick. The term derives from Adolf Fick, a 19th-century German physician who formulated what are now known as Fick's laws of diffusion. In this sense, 'Fickiaanse' refers to processes in which the diffusive flux is proportional to the negative gradient of concentration, so that J = -D ∇C, with D as the diffusion coefficient.
Under the common assumption of constant D in a homogeneous medium, Fick's first law applies to steady-state
Fickiaanse diffusion presumes no memory effects and no coupling to reactions or mechanical deformation. In many
