Let us note this point that the velocity of particle aggregation moving in a Newtonian liquid under the influence of gravity is faster than isolated particle,as evidenced in the optical absorbance measurements,while the sedimentation slows down for the CI/DA suspension with a phase volume of 20%.This illustrates that the flocculation of dimer covered iron particles must be loose,open, containing significant amounts of immobilized suspending medium in the microstructures [32], and in the stationary state the relative height is higher since the packing capacity is smaller
