Diffusion in solids is an atomic level transport process driven by chemical potential gradients. The diffusing material may be an atom of the host lattice (self diffusion) or an atom of another type ...

We consider the problem of identifying an unknown diffusion coefficient in a nonlinear diffusion equation from overspecified data measured on the boundary. Conditions ensuring compatibility of the ...

The translational diffusion coefficient and the partition coefficient of a spin-labeled solute, di-t-butyl nitroxide, in an aqueous suspension of dipalmitoyl lecithin vesicles have been studied by ...
