Here’s the link to the study in Science: https://www.science.org/doi/10.1126/science.adj6728 https://www.science.org/doi/10.1126/science.adj6728 I found their editor’s summary informative: > Basic chemistry tells us that dissimilar compounds such as oil and water won’t mix without the aid of a surfactant. Typically, the addition of a third component is needed to allow droplets of one to be stabilized within the other. Nannette et al. have revealed an exception to this behavior: the mixing of water with a polymeric oil. When a thin layer of oil absorbs onto the surface of water droplets, it stabilizes the droplets and causes a weak attraction between them, leading to long-term stability. —Marc S. Lavine Their supplementary materials, which include their methods, are openly available: https://www.science.org/action/downloadSupplement?doi=10.1126%2Fscience.adj6728&file=science.adj6728_sm.pdf https://www.science.org/action/downloadSupplement?doi=10.112... I wish I could access the study itself, but alas. From the methods and discussions it sounds to my layman’s ears like they use oils modified for cross-linking potential then went water-into-oil pretty slowly, in an environment that shears the whole situation into thin sheets at the interface. And that the novelty is that the cross-linked oils, polymerized around these little water spheres, were stable enough to resist coalescing even without the help of a surfactant to repel the little droplets from one another?
