Curvature dependence of the interface thermal conductance has previously been reported from simulations of other systems including simpler solid nanospheres in mono-atomic Lennard-Jones fluids, and nanodroplets of n-decane in water, as well as solid and liquid ZnO nanoparticles in tetradecane. In those cases, as with our simulations of the gold-water interface, δ > 0 and the interface conductance increased with curvature (decreases with particle size) (Table , Supporting Information). In contrast, G from simulations of bare spherical AuNPs in hexane exhibited the opposite trend with δ < 0 (G decreases with curvature). In this case, the curvature dependence was attributed to size dependent changes in the structure, coordination, and vibrational modes of the AuNP surface atoms. In the case of n-decane nanodroplets, the increase in G with curvature (i.e., δ > 0) was attributed to a reduction in the nanodroplet-water interface tension, while in the case of solid nanospheres in momo-atomic fluid Tascini et al. found that δ > 0 corresponded to curvature dependent differences in solvent adsorption density at the nanoparticle surfaces. 2.2 Analysis of water adsorption at the nanoscale-gold surfaces
