Phase transitions of inhomogeneous liquids in pores or at interfaces

被限制在窄孔中的液体（例如，碳纳米管中的水，中孔材料中的氧等）和界面处的流体（例如，油和水之间的界面）表现出对于本体流体相永远不会观察到的相变或复杂的相行为。我们的理论研究的一个目标是提取和理解一些基本性质的限制和界面流体。统计力学和计算机模拟是研究这些问题的工具。通过这些方法，我们发现了决定氩在纳米孔中相行为的几个关键因素，并在标准平均场密度泛函模型中揭示了四种润湿转变。

Liquids confined in narrow pores (e.g., water in carbon nanotubes, oxygen in meso-porous materials, etc) and fluids at interfaces (e.g., interfaces between oil and water) exhibit phase transitions or complex phase behavior that would never be observed for bulk fluid phases. A goal of our theoretical study is to extract and understand some fundamental properties in confined and interfacial fluids. Statistical mechanics and computer simulation are the tools to study these problems. With these approaches we found several key factors determining phase behavior of argon in nanopores and revealed four kinds of wetting transitions in a standard mean-filed density functional model.
