a−c Illustration and results for different evolution scenarios. a Oil dewetting from a spherical particle (shown in purple) to form of dome-shaped Janus particles. The particles always adopt a dumbbell shape and a fixed C∞ symmetry. b Oil dewetting from an octahedral particle (shown in blue) to form Janus particles with various Cn symmetries; the process is stepwise and asymmetric. c Oil dewetting an octahedron with a symmetric constraint (shown in red). The dewetting direction (or the direction of oil movement) is indicated by red arrows. d Plot showing the relative contact area (with respect to the overall surface of the particle) decreases continuously (for dewetting spherical particle) or stepwise (for dewetting octahedral particle), with increasing contact angle. e Comparison of the surface energies of Janus UiO-66 particles by asymmetric and symmetric dewetting. f The ratio χ between the relative contact area and the number of facets in contact stays roughly the same.
