A thermodynamic limit of the melting/freezing processes of water under strongly hydrophobic nanoscopic confinement.
We studied liquid water confined within nanopores which present a high level of hydrophobicity thanks to a new method of synthesis. We found that the liquid state persists down to temperatures much lower than in the bulk and in hydrophilic materials of comparable sizes, allowing us to define a thermodynamic limit for the melting/crystallization of water.
