WebThe effective hydrodynamic radii of small uncharged molecules in dilute aqueous solution were determined using Einstein's classical theory of viscosity. The radii thus obtained are …
WebDec 6, 2012 · The Stokes radius, often called the hydrodynamic radius, has been applied to gas bubbles (e.g., []) and colloidal particles (e.g., []) that are many-fold larger than the molecules of the liquid in which they move, so that the latter can be considered to be a viscous continuum.However, in many applications to molecules and to ions in solution the … Webradius ̟is independent of radius, which, in turn, implies that ∇×v ≃ 0. So this is a vortex without much vorticity! (except, as we shall see, a delta-function spike of vorticity right at …
WebThe effective radius of an ion in a solution measured by assuming that it is a body moving through the solution and resisted by the solution’s viscosity. If the solvent is water, the hydrodynamic radius includes all the water molecules attracted to the ion. WebSep 26, 2003 · Furthermore, we have combined the viscosity and diffusion calculations in order to compute an effective hydrodynamic radius of the particles in the mixtures, using the Stokes–Einstein relation. This analysis indicates that there is no collective diffusion of molecular clusters in these mixtures.
