Figure 4
USAXS profiles of the silica colloidal suspension (RS ≃ 300 nm and ϕ ≃ 0.014) at different times after shaking. The inset displays the scattering form factor of the particles measured over an extended q range using a dilute sample (ϕ ≃ 0.003). The fit corresponds to the polydisperse sphere form factor (RS ≃ 300 nm and σR ≃ 5.4 nm). |
