Interplate distances surface potentials

FIGURE 6.3 Distributions of small ions (n+ solid line n dashed line) for the interplate distance dx = 20 nm, the electrolyte concentration c = 0.001 mol T1 and the surface potential < >s = -4.0 in the Dirichlet model (the surface charge density Z0 = -0.084 nm-2 in the Neumann model). The origin of the coordinate x is taken at the midpoint between the container surfaces. 

FIGURE 6.10 Trajectories of the stable interplate distance d n plotted against the concentration c of the external soaking solution for three values of the surface potential s in the Dirichlet model. The width of the container is set to be 200 nm and D1 = Dr The swelling is enhanced for small values of <6S. ...
