The viscosities of liquid metals vaty by a factor of about 10 between the empty metals, and the full metals, and typical values are 0.54 x 10 poise for liquid potassium, and 4.1 x 10 poise for liquid copper, at dreir respective melting points. Empty metals are those in which the ionic radius is small compared to the metallic radius, and full metals are those in which the ionic radius is approximately the same as tire metallic radius. The process was described by Andrade as an activated process following an AiThenius expression...

From the rate of diffusion of radioactive Pb in molten lead, Andrade estimated that it takes an atom about 2 X 10 u second to move a distance equal to its own diameter.1 If the period of atomic vibration is 5 X 10 ,s second, this time is equivalent to idK)lit 40 atomic vibrations. From the considerations brought forward by Andrade, it appears that the same estimates would apply to liquid mercury above its melting point—that is, near room temperature. When we ask how often the particles of such a liquid change neighbors, it is clear that the rate of turnover is extremely large. If, for example, in (37) we set r0 equal to 1010 second, the chance that two particles remain in contact for as long as 7 X 10-10 second is less than one in a thousand.

The qualitative thermodynamic explanation of the shielding effect produced by the bound neutral water-soluble polymers was summarized by Andrade et al. [2] who studied the interaction of blood with polyethylene oxide (PEO) attached to the surfaces of solids. According to their concept, one possible component of the passivity may be the low interfacial free energy (ysl) of water-soluble polymers and their gels. As estimated by Matsunaga and Ikada [3], it is 3.7 and 3.1 mJ/m2 for cellulose and polyvinylalcohol whereas 52.6 and 41.9 mJ/m2 for polyethylene and Nylon 11, respectively. Ikada et al. [4] also found that adsorption of serum albumin increases dramatically with the increase of interfacial free energy of the polymer contacting the protein solution.
