Diffusion in confined geometries - in contrast to transport - refers to the case where no driving force (chemical potential gradient, e.g. density/pressure/electric field) is applied, or where the transport due to the driving force can be neglected due to the vanishing gradients (which is typically the case in smallest pores).
