Mass transport on nanoscale has specific features because of the presence of high number of grain- and interphase boundaries, as well as because of the fundamental problems related to the very short diffusion distances. In the first part examples on the changes (as the micro-metre scale is reduced to nanometre dimensions) of the overall mass transport due to the boundary effects are exposed. Then examples of processes, in which the diffusion coefficient depends strongly on the concentration (non-linearity) and the diffusion distance is typically few nanometres, will be discussed.
