Figure 3: Diffusion–viscosity decoupling.
From: Dynamic heterogeneity controls diffusion and viscosity near biological interfaces
Decoupling is shown by γ>1. Ratios are plotted as a function of surface charge on a flat silica surface, a Lennard–Jones fluid near a surface, and water on a lipid bilayer. Ratios are computed for the fluid layer close to the surface. Error bars show estimates for the s.e. of the ratio means. The inset shows the same data, plotted according to ‹tp› ∝ ‹tx2›/‹tx› (see Methods section).
