Fig. 3.

(a) log P_v as a function of $(N-\langle N\rangle )/\sqrt{\langle \delta N^2\rangle }$ for volumes of four different shapes: a sphere of radius 0.6 nm, a cube of side 0.9 nm, a ylinder of radius 0.3 nm and length 3 nm, and a thin cuboid of dimensions 0.3 nm × 1.6 nm × 1.6 nm. (b) The ratio of μ^ex to surface area A, as a function of A/v for the four different shapes. The dashed line represents the surface tension, γ_∞, of a vapor-liquid interface of SPC/E water [18].
