has been granted a patent for a coating composition comprised of (a) a film-forming resin; (b) a porous solid comprised of an ion-exchange ceramic comprised of pores having antimicrobial metal ions disposed therein; and (c) a halogen ion-containing onium compound having a minimum molecular diameter
according to the equation: D.
A new strategy involves the use of nanopores - orifices of molecular diameter
that connect two fluid reservoirs.
Thus He, with the smallest molecular diameter
, has the highest permeation rate.
Subsequently, it was shown that diffusivities for gases and vapors in glassy PS and PMMA, in addition to PVC, are strong exponential functions of molecular diameter (5).
Several measures of molecular diameter were used in establishing these correlations: Gas viscosity measurements yield the Lennard-Jones force constant diameters, [d.
How do molecules of such a liquid shift and roll when they are wedged between moving surfaces only a few molecular diameters
