“…Wetting and dewetting of microporous media, i.e., materials with pores diameter smaller than 2 nm, is of great importance for broad range of technological and natural systems. , Among others, energy-absorbing and energy-storing systems have attracted considerable attention in recent years as they are expected to play a crucial role in a future carbon free society . Many of these systems transfer mechanical energy through pressurized intrusion–extrusion cycles of a liquid into/out of a porous material. , The wetting and dewetting of a microporous material is a truly multiscale process, in which the emerging characteristics of the intrusion/extrusion cycle exhibit a nontrivial dependence on physio-chemical details at the molecular level: the type of material, its structure and morphology and its chemical composition. , Thus, a microscopic understanding of the intrusion and extrusion processes is key to design novel, high-performance materials.…”

Zeolitic Imidazolate Frameworks (ZIF) find application in storage and dissipation of mechanical energy. Their distinctive properties linked to their (sub)nanometer size and hydrophobicity allow for water intrusion only under high hydrostatic pressure. Here we focus on the popular ZIF-8 material investigating the intrusion mechanism in its nanoscale cages, which is the key to its rational exploitation in target applications. In this work, we used a joint experimental/theoretical approach combining in operando synchrotron experiments during highpressure intrusion experiments, molecular dynamics simulations, and stochastic models to reveal that water intrusion into ZIF-8 occurs by a cascade filling of connected cages rather than a condensation process as previously assumed. The reported results allowed us to establish structure/function relations in this prototypical microporous material, representing an important step to devise design rules to synthesize porous media.

“…We consider an axially symmetric capillary around the z axis whose inlet is at z = 0. We borrow the concept of transient state of the classical nucleation theory 4,6 , and assume an imbibition pathway along the capillary with a constant Young's contact angle 6,21,39 . Then, the solid-liquid surface free energy when the liquid-vapor interface reaches z is given by 39…”

“…Imbibition (intrusion and extrusion) of liquid in microscale and nanoscale capillaries is one of the most fundamental problems of thermodynamics of liquid in confined space not only in various field of natural science [1][2][3][4][5][6] but also in various engineering problems in micro-and nano-scale [7][8][9][10][11][12][13] . Recently, there have been growing interests in addressing the problem of imbibition in asymmetric capillaries with geometrical gradient 5 because it is relevant to the engineering [14][15][16] of various micro-and nano-fluidics functional devices.…”

“…Although a large amount of literature on double conical capillaries has already been accumulated 5,[7][8][9][11][12][13] , most of the theoretical works studied transport properties numerically using macroscopic fluid dynamic equations [17][18][19][20]27,32,33 or atomic molecular dynamic simulations 23,24,28,29 which are limited to sub nano-scale. Relatively few studies based on thermodynamics have been conducted to understand the quasi-static imbibition processes 4,21,[35][36][37][38][39] . In particular, pressure-controlled intrusion and extrusion, or infiltration and defiltration, and, furthermore, infiltration pressure 10,[40][41][42][43] must be important not only to understand macroscopic natural and geographic problems 5 but also to design micro-and nano-fluidic devices.…”

Thermodynamics and hydrodynamics of spontaneous and forced imbibition of liquid into conical capillaries are studied to assess the feasibility of a conical liquid diode. The analytical formulas for the Laplace pressure and the critical Young's contact angle of the capillary for the onset of spontaneous imbibition are derived using the classical capillary model of thermodynamics. The critical contact angle below which the spontaneous imbibition can occur belongs to the hydrophilic region for the capillary with a diverging radius while it belongs to the hydrophobic region for the capillary with a converging radius. Thus, by choosing Young's contact angle between these two critical contact angles, only the spontaneous imbibition towards the converging radius occurs. Therefore, the capillary with a converging radius acts as the forward direction and that with a diverging radius as the reverse direction of diode. Even under the external applied pressure, the free-energy landscape implies that the forced imbibition occurs only to the forward direction by tuning the applied pressure. Furthermore, the scaling rule of the time scale of imbibition is derived by assuming Hagen-Poiseuille steady flow. Again, the time scale of forward direction is advantageous compared to the reverse direction when the imbibition to both direction is possible. Therefore, our theoretical analysis shows that a conical capillary acts as a liquid diode.

Forced wetting (intrusion) and spontaneous dewetting (extrusion) of hydrophobic/lyophobic nanoporous materials by water/nonwetting liquid are of great importance for a broad span of technological and natural systems such as shock-absorbers, molecular springs, separation, chromatography, ion channels, nanofluidics, and many more. In most of these cases, the process of intrusion-extrusion is not complete due to the stochastic nature of external stimuli under realistic operational conditions. However, understanding of these partial processes is limited, as most of the works are focused on an idealized complete intrusion-extrusion cycle. In this work, we show an experimental system operating under partial intrusion/extrusion conditions and present a simple model that captures its main features. We rationalize these operational conditions in terms of the pore entrance and cavity size distributions of the material, which control the range of intrusion/extrusion pressures.
