Recently, alternative methodologies have been developed to enable the calculation of W SL , without requiring the simulation of nano-scale droplets. Instead these approaches rely on thermodynamic integration. The phantom wall method involves the use of a virtual piston to separate separate the solid and liquid phases, whilst the dry-surface method involves perturbing the interactions between the solid and liquid phases by introducing a coupling parameter, λ, to transition from a state where interactions are fully coupled, to a fully decoupled state. In this work we will employ the dry-surface method with damped Coulomb interactions, as proposed by Surblys et al. To calculate W SL , simulations were performed using the same system as used in previous R K calculations. It was suggested by Surblys et al. that systems with long-range Coulombic interactions require the solution of additional Poisson equations when performing dry-surface calculations. As a solution, the long-range Coulombic potential for solid-liquid interactions was replaced with a new potential which made use of damped Coulombic interactions:
