    Notes: Liquid membranes containing a macrocyclic polyether can move or pump a specific cation against its concentration gradient. The cation flux is not proportional to the difference of the cation concentration but to the difference of the product of cation and anion concentrations across the membrane. The results are inconsistent with existing theories of ion transport, but can be explained in terms of ion pairs.

    Notes: Copper can be selectively separated and concentrated by diffusion across liquid membranes. These membranes are effective either as thin films supported by porous polymer sheets or as liquid microcapsules or liquid surfactant membranes.

    Explaining solubilization kinetics (1976)

    Notes: Solubilization rates of fatty acids in pure detergent solutions are controlled by mixed micelle desorption and diffusion. Solubilization rates in partially saturated detergent solutions also involve exchange of fatty acids between the solid and the solution. These conclusions depend on models like those used in gas-solid catalysis and in tracer diffusion.
