(a) Long-exposure image of a binary monolayer (ϕ = 0.14) sheared at 3 Hz in the co-moving reference of the rotating disk, highlighting the flow-induced structuring around the disk. (b) Normalized radial position probability distributions P(r/R) of large particles at 0, 5 and 10 seconds after the disk starts to rotate at 1.5 Hz. (c) Steady state P(r/R) for a monolayer sheared at 0.3 Hz (red data) and 1 Hz (blue data). Empty and filled symbols denote 1 μm and 4 μm particles, respectively. (d) Normalized angular velocity profiles corresponding to (c), obtained by tracking large and small particles (filled and open circles) and by image correlation (empty triangles), as discussed in the ESI.
