Research Abstract

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.
