WebNow let us consider the case where drug is incorporated uniformly, but above its solubility. We assume that the Thiele modulus is high. This condition is actually more likely to be true for hemispheres than for slabs or other “outward releasing” geometries, since diffusion is slowed by the constricted release geometry. Web30 Jul 2015 · When the system is strongly mass transfer limited (Thiele Modulus≫1) it can be represented by slab geometry in order to determine the shell thickness. Otherwise, the analysis is done on a ...
