Variation of the isoelectric point as a function of the flow penetration degree, for various values of the nominal charge density ratio Inline graphic for layers 1 and 2 (panel A) and different values of Inline graphic (panel B). Model parameters, panel A: Inline graphic and Inline graphic Model parameters, panel B: the same as in A with Inline graphic and variable Inline graphic (C) Variation of the isoelectric point as a function of the electrolyte concentration and the ratio Inline graphic Model parameters, panel C: as in A with Inline graphic nm, Inline graphic In all these calculations, Eqs. 3546 are used (particle composed of two concentric soft layers, Eq. 46).
