RT Journal Article T1 Solid−Liquid Interfacial Free Energy from Computer Simulations: Challenges and Recent Advances A1 Pasquale, Nicodemo Di A1 Algaba Fernández, Jesús A1 Jiménez Blas, Felipe A1 Rovigatti, Lorenzo AB The study of interfacial properties in liquid−liquid and liquid−vapor systemshas a history of nearly 200 years, with significant contributions from scientific luminaries suchas Thomas Young and Willard Gibbs. However, a similar level of understanding of solid−liquidinterfaces has emerged only more recently, largely because of the numerous complicationsassociated with the thermodynamics needed to describe them. The accurate calculation of theinterfacial free energy of solid−liquid systems is central to determining which interfaces will beobserved and their properties. However, designing and analyzing the molecular dynamicssimulations required to do this remains challenging, unlike the liquid−liquid or liquid−vaporcases, because of the unique complications associated with solid−liquid systems. Specifically,the lattice structure of solids introduces spatial directionality, and atomic configurations insolids can be altered by stretching. The primary aim of this review is to provide an overview ofthe numerical approaches developed to address the challenge of calculating the interfacial freeenergy in solid−liquid systems. These approaches are classified as (i) direct methods, whichcompute interfacial free energies explicitly, albeit often through convoluted procedures, and (ii) indirect methods, which derive thesefree energies as secondary results obtained from the analysis of simulations of an idealized experimental configuration. We alsodiscuss two key topics related to the calculation of the interfacial free energy of solid−liquid systems: nucleation theory and curvedinterfaces, which represent important problems where research remains highly active PB American Chemical Society SN 0009-2665 SN 1520-6890 (electrónico) YR 2025 FD 2025-05 LK https://hdl.handle.net/10272/25558 UL https://hdl.handle.net/10272/25558 LA eng NO Di Pasquale, N., Algaba, J., Montero de Hijes, P., Sanchez-Burgos, I., Tejedor, A.
