Ga. Krystev et Di. Dakova, Floating of large, heavy particles induced by sedimentation of small particles in liquid polydisperse systems, COLL J, 61(5), 1999, pp. 659-660
The unusual effect of buoyancy of large, heavy particles in liquid polydisp
erse systems induced by sedimentation of small particles is described. A ph
ysical mechanism of this effect was elucidated, and some its applications i
s proposed.
