Webusing the differential form of Fick’s law. Magnetic resonance imaging (MRI) was used to obtain spatially and time-resolved profiles of the diffusion of H 2O from an agarose gel to a neighboring D 2O reservoir. The differential form of Fick’s second law was used to solve for the diffusion coefficient, D =1.3×10−9 m2 s−1. MRI is well ... WebFick's first law for dilute solutions is from which Thus we arrive at Fick's second law in the form Utilizing: The Boltzman transformation We will use a modified form of the Boltzman Transform Changing Variables Let Transformed boundary conditions C A = 0, C A = C Ao, Probability function definition (and value ) The following solution results
