abstract = {<p style="text-align: justify;">The coarsening kinetics of a two-phase mixture with a large diffusional mobility
disparity between the two phases is studied using a variable-mobility Cahn Hilliard
equation. The semi-implicit spectral numerical technique was employed, and
a number of interpolation functions are considered for describing the change in diffusion
mobility across the interface boundary from one phase to another. The coarsening
rate of domain size was measured using both structure and pair correlation functions
as well as the direct computation of particle sizes in real space for the case that the
coarsening phase consists of dispersed particles. We discovered that the average size
