A new study finds the sedimentation of asymmetric objects in liquid is very different from that of symmetrical objects like spheres. The research may have practical applications in improving water ...

FOR the observations of concentration distribution in an ultracentrifuge cell during the process of sedimentation, methods depending on light absorption or refractive index have been used 1, 2.

Two systems of spheres sedimenting in a viscous medium have received considerable attention: (1) initially uniform dispersions containing a large number of particles; (2) single spheres (the Stokes ...

Suspensions may be acceptably stable to sedimentation for two reasons. Either the bulk material has a yield stress high enough to hold the particles in suspension, or the material has a ‘zero shear ...
