WebMar 1, 2024 · Also, Fickian diffusion dominates the drug transport mechanism of all air-dried samples during the study period. However, the Fickian contribution was gradually reducing with time. Porosity significantly effects the drug transport mechanism as case II relaxation dominates after day 10 of the lyophilized microparticles. WebThe difference is that Fickian diffusion depends on the mean of the component mobilities (and a thermodynamic factor), and thermal diffusion depends on the relative temperature-dependence of the component mobilities, i.e., relative activation energies.
