Figure 1

Plot showing adsorption (open symbols) and desorption (solid symbols) along with fits with Eq. (7) of Ref. 2 (solid, dotted, and dashed curves). The dotted curve is what appeared in the original publication with $R=12\mathrm{nm}$ using Eq. (7) with the second term approximated to “$\gamma /nR$” valid for $d\ll R$. The solid curve is a fit also with $R=12\mathrm{nm}$, this time without the approximation of the second term of Eq. (7). The dashed curve shows a fit with $R=16\mathrm{nm}$, again without the approximation of the second term.
