Wetting and melting in a methane/graphite system

Solid-liquid stratification, related to surface melting in the bulk, may occur in a system that also exhibits triple-point dewetting. Each phenomenon has distinctive asymptotic thermodynamic behavior in the thick-film limit. NMR data show that solid ethane wets graphite to at least 50 layers and tha...

Summary:Solid-liquid stratification, related to surface melting in the bulk, may occur in a system that also exhibits triple-point dewetting. Each phenomenon has distinctive asymptotic thermodynamic behavior in the thick-film limit. NMR data show that solid ethane wets graphite to at least 50 layers and that capillary condensation is not nucleated. An increase in molecular mobility associated with surface layers of the roughened solid phase is also observed.
