Surface diffusion is the major intraparticle transport mechanism.
With this method, it was found possible to measure the surface diffusion steps of adatoms and the corresponding adsorption capacity.
We first extended the 243 clinically measured surface Smax values across the entire ventricular walls by solving a diffusion problem.
The phenomenon is characterized by two-dimensionless groups, one measuring the strength of the surface diffusion process with respect to the nonlinear creep deformation in the interior of the solid, and the other the magnitude of the surface energy of the void in relation to the applied load and the size of the void.
KMC simulations on segregation of ice mixtures, a direct measure of bulk diffusion, showed that experimental results can only be qualitatively reproduced if both surface diffusion and bulk diffusion by swapping of molecules between sites is included.
Finally, in a more mechanistic model of yeast cell polarization, a surface diffusion coefficient between 0.01 and 0.001 µm2/s produced the best polarization performance, and this range is close to the measured value.

A simple diffusion resistance model is shown to be sufficient to capture the effects of both intracrystalline and surface diffusion resistances, thus properly linking simulation to experimental evidence.
