These experiments were made to obtain more information about the surface of the red blood cell. Since "surface" means different things to different people, we shall define our meaning now. Strictly speaking, the surface studied by electrophoresis is the surface of shear between the cell (moving in the electric field) and the surrounding medium, for it is the potential at this surface which is t...

Ionic liquids have shown promise as replacements for water in ionic polymer transducers. Ionic liquids are non-volatile and have a larger electrochemical stability window than water. Therefore, transducers employing ionic liquids can be operated for long periods of time in air and can be actuated with higher voltages. Furthermore, transducers based on ionic liquids do not exhibit the characteri...

The addition of dopants with a small ionic radius led to strong binding H atoms, and the balance H+ reactivity (mobility) coverage was fundamentally important for high conductivity catalysis involving surface protonics.

Extensive Monte Carlo simulations and scaling arguments are used to study the colloidal charge reversal. The critical colloidal surface charge density sigma(c) at which the reversal first appears is found to depend strongly on the ionic size. We find that sigma(c) has an inflection point as a function of the electrolyte concentration. The width of the plateau region in the vicinity of the infle...

The electrolytic conductivities for C.I. Acid Orange 15 and C.I. Acid Red 97 have been studied. The electrolytic conductivities have been analyzed by Deby HUckel-Onsager theory, The degree of ionization, α, Van’t Hoffs factor, i, and thickness of ionic atmosphere, X –1 . were calculated. Each value diminishes with increasing dye concentration. The dye anion transport number, t, mobility’s, μ we...

A fluctuation theory for electrolyte solutions is developed based on the coupling between the equations of nonequilibrium thermodynamics and the Poisson equation. The resulting fluctuation theory is applied to the analysis of electrophoretic light scattering. It is shown that in a binary electrolyte solution (two ionic species), the Doppler shift is not determined by the electrical mobility of ...

Thixotropy implies non-equilibrium initial conditions after remolding. At the macroscale, thixotropy manifests as the regain in mechanical properties. At the microscale, thixotropy involves phenomena such as contact creep and interparticle force redistribution, homogenization of pore pressure (in saturated and partially saturated soils), altered ionic distribution and mobility, and the effects ...

Melittin, a cationic hemolytic peptide, is intrinsically fluorescent due to the presence of a single functionally important tryptophan residue. We have previously shown that the sole tryptophan of melittin is localized in a motionally restricted environment in the membrane interface. We have monitored the effect of ionic strength on the organization and dynamics of membrane-bound melittin utili...

The electrophoretic behaviour of some metal ions and anions has been studied on Whatman No. 1 paper strips impregnated with zirconnium(IV) phenylethylamine; acetate buffers of different pH were used as background electrolytes. The effect of the ion-exchange material on the mobility of the ionic species was examined. It was found that impregnation of the paper with zirconium(IV) phenylethylamine...
