Abstract
There is a continuing interest in “2D solids” which appear at various interfaces for their novel structure and dynamics. Many simple molecules are adsorbed on solid surfaces, such as graphite, to form 2D layers that are solid at low temperatures. Interestingly, similar solid monolayers are formed at the interface between bulk liquid adsorbates and graphite. In this work, we report a 2D-like ice structure which appears in the initial stage of crystallisation of aqueous solutions from the undercooled state. We present results obtained by neutron scattering to demonstrate the formation of this novel structure and its temperature evolution.
