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