标题： Grain Boundary Premelting of Monolayer Ices in 2D Nano-channels

摘要： 我们采用分子动力学（MD）模拟来研究受限于二维疏水纳米通道中的冰的晶界（GB）预熔现象。 在单层冰中的对称倾斜晶界中观察到预熔转变，其涉及液相水的预熔带的形成，该带的宽度随着接近熔化温度而对数增长，这与现有的晶界预熔理论一致。 基于当前的MD观测，可以预期晶界预熔存在于受限冰的广泛低维相中，并对低维冰的晶体生长产生重要影响。 显示英文摘要

摘要： We employ molecular-dynamics (MD) simulations to study grain boundary (GB) premelting in ices confined in two-dimensional hydrophobic nano-channels. Premelting transition is observed in a symmetric tilt GB in monolayer ices an involves the formation of a premelting band of liquid phase water with a width that grows logarithmically as the melting temperature is approached from below, consistent with the existing theory of GB premelting. Based on current MD observations, one may expect GB premelting exists over a wide range of low dimensional phases of confined ice and shows important consequences for crystal growth of low dimensional ices.
