Pressure on the wall against the radius of the pore obtained for values of the activity z, and bulk density ρ b listed in Table I (z and ρ b increase from bottom to top). The dashed line indicates the radius R = 0.612 for which a maximum of three particles can be fitted in the cavity.
Relative adsorption in the pore as a function of the bulk density plotted for different radii of the pore R = 0.2, 0.4, 0.5, 0.525, 0.55, 0.575, 0.6, 0.61237, 0.65, 0.7, 0.8, 1, 1.2, and 1.5. The arrow marks the direction of increasing values of R. The asterisk indicates the curve for R = 0.61237.
Mean number of particles vs. bulk density for different radii of the pore. The arrow, the asterisk and the values of R were described in Fig. 2.
Standard deviation in N as a function of N for different radii of the pore. The arrow, the asterisk and the values of R were described in Fig. 2.
Fluid-substrate surface tension vs. pressure. The filled circles and squares correspond to simulation and thermodynamic integration data from Ref. 21,22, respectively. The dashed line shows SPT values.20 The parametric plot of the power series βP(ρ b ) and βγ∞(ρ b ) is shown by the continuous line.
Tolman length vs. density. The continuous curve with the open circle corresponds to the linear dependence in ρ b from this work. The six SPT versions from Refs. 20 and 23 are shown by non-continuous curves: SPT3 (dotted line), SPT6 (short dashed line), CS-SPT (dashed line), SPT6M (short dashed-dot line), CS-SPT M (dashed-dot line), and ESPT (dashed-dot-dot line that lies above all other lines). The graphic includes at the top left corner a close up of the curves around ρ b = 0.
Activity values z, used for the curves plotted in Fig. 1 and the corresponding bulk density values, ρ b .
