Universal nanodroplet branches from confining the Ouzo effect.
Proc Natl Acad Sci U S A
September 2017
We report the self-organization of universal branching patterns of oil nanodroplets under the Ouzo effect [Vitale S, Katz J (2003) 19:4105-4110]-a phenomenon in which spontaneous droplet formation occurs upon dilution of an organic solution of oil with water. The mixing of the organic and aqueous phases is confined under a quasi-2D geometry. In a manner analogous to the ramification of ground stream networks [Devauchelle O, Petroff AP, Seybold HF, Rothman DH (2012) 109: 20832-20836 and Cohen Y, et al.

- The research explores how dense suspension droplets splash upon hitting solid surfaces, highlighting the role of liquid viscosity.
- The splashing phenomenon is influenced by the kinetic energy of particles overcoming surface tension (Weber number) and is suppressed by higher solvent viscosity (Stokes number).
- A unique phase diagram was created, revealing that at low Stokes numbers, droplets can bounce back rather than splash, a behavior explained through simulations of particle interactions.
