(a) F _s (q, t, t _w ) decay curves at various t _w for Laponite-PS suspensions (Laponite concentration C _L  = 3.0 wt.%, and PS volume fraction ϕ _PS  = 5.66 × 10⁻⁵). The solid lines are fits to Eq. 9. (b) Plots of \({\chi }_{{t}_{w}}\)(q, t) = t _w ∂F _s (q, t, t _w )/∂t _w as a function of delay time t for curves shown in Fig. 3(a). (c) F _s (q, t, ϕ) decay curves at various ϕ at t _w  = 3 h. The solid lines are fits to Eq. 10. (d) Plots of χ _ϕ (q, t) = ϕ∂F _s (q, t, ϕ)/∂ϕ as a function of delay time t for curves shown in Fig. 3(c).
