Based on our theoretical framework, we postulated that the perturbations within the water network predominantly stem from the dangling water entities engaged in surface protrusions, thereby facilitating the transport of water from the droplet to the oil phase. To support this hypothesis, we presented the two-dimensional spatial density ρ(x, y) distribution of the water droplet, in the systems with and without tbp, as shown in Figure . The distributions show that the interaction between tbp and the water droplet creates significant interfacial heterogeneity leading to the formation of water microhannels and protrusions of different shapes and sizes near the droplet surface. These micro-structures were responsible for driving water transport from the droplet surface to the oil phase. Protrusion-driven water transport can be envisioned as a unidirectional transport mechanism, distinct from other mechanisms such as diffusion. This is because it is highly unlikely for water disintegrating via protrusion formation to follow the exact same pathway back to the larger droplet. The increased number of pathways makes protrusion-driven water transport unique, warranting further studies to fully uncover its thermodynamics and kinetics under various conditions. A typical simulation snapshot showing the transport of water through the protruding structure is depicted in Figure C. Some differences in the structure of protrusions can be expected based on factors such as amphiphile concentration, topology (including chain length or polar groups), and other physico-chemical conditions. Importantly, these protruding surface structures create tailored microenvironments that enhance chemical reactivity and catalysis, providing a favorable environment for liquid/liquid surface reactions.
