Figure 4
Diffusion constant D associated with the dynamics of the colloidal particles (radius a) in shear flow as a function of q measured in a transverse flow (q ⊥ v) geometry for three volume flow rates (squares, crosses and triangles). Values for the diffusion coefficient obtained from longitudinal flow scans (q ∥ v) with static samples are also shown (circles). The dashed line shows the estimated value for the diffusion constant (see text).
