Time evolution of the DWS autocorrelation functions and of the q dependence of the scattered intensity of a 26% particle suspension undergoing a sol–gel transition. (a) Stable suspension at t = 0 min and time evolution after destabilization for t = 15 and 30 min before the gel point (from bottom to top). Inset: time evolution of the characteristic time [\tau_c]. (b) Correlation functions [[g_{2}(\tau)-1]_{\rm erg}] in the gel state for t = 55, 80, 105 and 210 min (from bottom to top). Inset: unshifted correlation functions for t = 55, 80, 105 and 210 min (from top to bottom). (c) SANS intensity curves [same symbols correspond to same times as in (a) and (b)].
