From: Cation hydration by confined water and framework-atoms have crucial role on thermodynamics of clay swelling

Figure 2

Number of water molecules adsorbed (\(N_W\)) per unit area of the mica surface (\(A_{xy}\)) in (black circle) Na-, (red square) Li-, and (blue diamond) H-mica pore at various pore widths (d). The solid line is the number based on bulk density of water (i.e., \(\rho _b = 0.0334\) \(\hbox {\AA}^{-3}\)). Inset shows the significant deviations in density of confined water (\(\rho _i\) normalized by \(\rho _b\)) at smaller d.
