SIPLI relaxation studies conducted on 20% w/w aqueous dispersions of G₃₇-H₈₀, G₅₄-H₁₄₀, and G₇₁-H₂₀₀ worms at various temperatures (20–40, 2–10, and 2–6 °C, respectively): (a–c) show the decay of the image intensity vs time after cessation of shear (the solid line represents a fit to an exponential decay); (d–f) show the temperature dependence of the characteristic half-life time, τ_1/2, required for worm relaxation (here the solid lines are merely a guide for the eye).
