Fig. 6: Types of disclination loops observed in two-core emulsions.
From: Topology controls flow patterns in active double emulsions

a + − + − charged loops observed for low activity. b Typical −1/2 disclination loop constrained to inner cores. c +1/2 -twist charged loop. d–f Writhed charged loops observed in the chaotic regime. g Comet-twist neutral loop.
