WebThe simple Fickian diffusion does not correctly describe molecular multicomponent … WebA diffusion process that does NOT obey Fick’s laws is known as Anomalous diffusion or non-Fickian diffusion. Fick’s Law of Diffusion is used to solve the diffusion coefficient D. There are two laws that are interrelated ie; Fick’s first law is used to derive Fick’s second law which is similar to the diffusion equation.

WebFickian diffusion refers to the solute transport process in which the polymer relaxation time (t r) is much greater than the characteristic solvent diffusion time (t d ). When t r t d, the macroscopic drug release becomes anomalous or non-Fickian [3]. What is fickian and non fickian diffusion? 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.
