Self-diffusivity of water in CNAs with Gaussian distribution of pore width. (a) Three Gaussian distributions of CNT diameters are considered, with different mean values μ or standard deviations σ. (b) Self-diffusion coefficient of water nanoconfined within CNTs distributed with Gaussian frequencies f _N and μ= 2.5 nm, σ= 0.5 nm; (c) μ= 5.0 nm, σ= 0.5 nm; (d) μ= 2.5 nm, σ= 1.5 nm.
