Nano-confinement effects on liquid pressure

In this study, molecular dynamics simulations are performed to estimate the equilibrium pressure of liquid confined in nanopores. The show that is highly sensitive pore size and can significantly change from absolute positive negative values for a very small (0.1 nm) size. contribution solid–liquid interaction always dominates first layer adjacent surface sensitiveness on dependent atom distribution layers. A influence number S introduced quantitatively characterize degree confinement. At constant system temperature, decreases with increasing based power-law function. nanopores large number, found be independent bulk pressure, whereas increases pressure.
