    "abstract": "Faraday surface instability measurements of the critical acceleration, a_c,\nand wavenumber, k_c, for standing surface waves on a tetracosanol (C_24H_50)\nmelt exhibit abrupt changes at T_s=54degC above the bulk freezing temperature.\nThe measured variations of a_c and k_c vs. temperature and driving frequency\nare accounted for quantitatively by a hydrodynamic model, revealing a change\nfrom a free-slip surface flow, generic for a free liquid surface (T\u003eT_s), to a\nsurface-pinned, no-slip flow, characteristic of a flow near a wetted solid wall\n(T \u003c T_s). The change at T_s is traced to the onset of surface freezing, where\nthe steep velocity gradient in the surface-pinned flow significantly increases\nthe viscous dissipation near the surface.",
