Strongly confined liquids:

Transport of liquids in nano-sized pores or narrow  channels is crucial for most natural and industrial processes. It can exhibit a series of fascinating behaviors when the confinement length scale is comparable to the molecular size. We explore this regime of confinement by simulating hard-spheres confined in a slit or wedge geometry. Our study suggests that the confinement length scale appears as another control parameter to the non-equilibrium phase diagram. In particular, we find that a wedge-like confinement with very very small tilt angle can promote a liquid-glass coexistence. Since there is a growing interest for smaller system in modern applications, these new findings can be utilized for future technological advancements.
