Abstract
To realize thermal energy storage system using solid-liquid phase-change materials, it is important to control their melting points. It is well known that the melting points in nanoporous media are different from bulk, though the mechanism of melting temperature change is not fully understood. Here, to predict melting points of materials confined in nanoporous media, we verify the Gibbs-Thomson equation. In our previous studies, the melting points of water and argon confined in nano-size space between two parallel walls were determined. In this study, we derive melting points through Gibbs-Thomson equation using surface tension and latent heat and compare to the melting points directly determined by molecular dynamics simulations.
