values of 915 ± 48 and 1004 ± 160 MW m -2 K -1 for non-polarizable gold with citrate and neat water, respectively. With the use of polarizability, these values jump to 1661 ± 403 and 1650 ± 329 MW m -2 K -1 , respectively. These do not appear to be reliable estimates of the true interfacial thermal conductance when the interface has spatial extent due to surface binding of an adsorbed species.
