We review the current state of knowledge of phase separation and phase equilibria in porous materials. Our emphasis is on fundamental studies of simple fluids (composed of small, neutral molecules) and well-characterized materials. While theoretical and molecular simulation studies are stressed, we also survey experimental investigations that are fundamental in nature. Following a brief survey of the most useful theoretical and simulation methods, we describe the nature of gas‐liquid (capillary… 
How liquid-liquid phase separation induces active spreading.
The interplay between phase separation and wetting of multicomponent mixtures is ubiquitous in nature and technology and recently gained significant attention across scientific disciplines, due to
Effect of Confinement on Capillary Phase Transition in Granular Aggregates.
Using a 3D mean-field lattice-gas model, we analyze the effect of confinement on the nature of capillary phase transition in granular aggregates with varying disorder and their inverse porous
Metastability at Defective Metal Oxide Interfaces and Nanoconfined Structures
Most of the paradigms in materials science and technology firmly rely on equilibrium materials, i.e., phases with the lowest Gibbs energy under thermodynamic conditions. In nature, however,
Ordering, clustering, and wetting of hard rods in extreme confinement
The effect of out-of-plane orientational and positional fluctuations is examined in the phase behavior of hard spherocylinders confined between two parallel walls. The stability of isotropic,
Probing predictions due to the nonlocal interface Hamiltonian: Monte Carlo simulations of interfacial fluctuations in Ising films.
An L×L×D slab geometry with oppositely directed surface fields is studied so that a single interface is formed and can undergo a localization-delocalization transition and its behavior is found to confirm theoretical predictions for D>6 lattice spacings.
Nanopore Confinement and Pore Connectivity Considerations in Modeling Unconventional Resources
Gas and liquid production from nanopore shale resources substantially increased during the past decade due to the advances in horizontal drilling and multistage hydraulic fracturing. Transport
Does capillary evaporation limit the accessibility of nonaqueous electrolytes to the ultrasmall pores of carbon electrodes?
This work studies the phase behavior of ionic fluids in slit pores using the classical density functional theory to demonstrate that the accessibility of micropores depends not only on the ionic diameters but also on their wetting behavior intrinsically related to the vapor-liquid or liquid-liquid phase separation of the bulk ionic systems.
