The equations describing chemical diffusion in the general case where the partial molal volumes of the diffusing components may differ and may vary with composition are reviewed and discussed. Exact and easily applied relations for obtaining chemical and intrinsic diffusivities are derived. The results ...

Matrix formulation of Maxwell’s equations The propagation of electromagnetic waves in an anisotropic material is determined by Maxwell’s equation in momentum space: k×(k×E)+ω2c2ϵ(ω)E=0, where k is the wave vector with frequency ω, c the velocity of light in vacuum, E the electr...

Equations 4 –7 can then be used to determine D from measured emission or sorption curves using least-squares regression.32 Therefore all three key parameters—Cm,0, K, and D— can be determined in one experiment. Because only D is determined by nonlinear least-square regression, the ...
The usual modified Nernst–Planck equations used in the pseudo-binary case (water plus counterions in an ion-exchange membrane) when neglecting convection are:J1=−D1c1∇μ1RT+x1[J3+J1],J3=−D3c3∇μ3RT+x3[J3+J1].In this equation, x1 represents the mole fraction of the counter-...
