Figure 3. Tracking exchange using two colours of particles.
(a–e) Confocal micrographs show that the clusters become more mixed as the sample is rolled. Simultaneously, the individual droplets become more heterogeneous; the scale bars are 100 μm. (f) The value of 〈| fd|〉 decreases with rolling time, with the rate of decrease being greater in samples containing particle bridges. (g,h) Histograms of f for the sample with ΦIM = 50% at two different rolling times. (i) Normalised plots of f at various rolling times for the sample with ΦIM = 50%.
