Abstract

Initially uniform suspensions of hydrophobic colloidal particles sediment in a manner that is not compatible with the elementary theory of Brownian motion. That is, the particles do not sediment to reach an equilibrium concentration that is linearly increasing with depth into the container but instead the concentration forms nearly constant layers and sharp transitions to higher densities as the depth increases. Recent experimental work by Siano confirms and delineates quantitatively this phenomenon. A theoretical explanation of Siano's experiments is given.
