(a) A schematic representation of the shear geometry employed for rheo-XPCS with the inner cylinder rotating at an angular velocity, ω. Below this are shown representative g2(q, t) functions for a dilute suspension of silica particles (mean radius ≃ 300 nm) for different shear rates at q = 4.2 × 10−3 nm−1 along the (b) horizontal and (c) vertical directions in radial configuration. The continuous lines are fits to (b) equation (4[link]) and (c) equation (1[link]) with equation (3[link]), with β ≃ 0.35. The undulations in g2(q, t) signify the dominance of the sinc term in equation (4)[link]. The insets present the deduced δv as a function of [\dot{\gamma}_{\rm a}].
