... Ions exist in solutions only in combinations with oppositely charged co-ions. Therefore we cannot experimentally measure the activity coefficient of an individual ion. In experiment, we can only able to determinate the mean activity coefficient, averaged by all the ions in the solution. The mean act ...

The Electrical Double Layer and Its Structure
... The concept of the existence of the double layer at the surface of a metal being in contact with an electrolyte appeared in 1879 (Helmholtz). That first theoretical model assumed the presence of a compact layer of ions in contact with the charged metal surface. The next model, of Gouy and Chapman, i ...

... In an electrical system, charges (electrons) move through a circuit because coulomb forces are exerted on the charges. Coulomb forces are caused by the presence of other charges. These other charges create an electric field and a potential difference. Potential difference is the prime mover in elect ...

Nanofluidic circuitry
Nanofluidic circuitry is a nanotechnology aiming for control of fluids in nanometer scale. Due to the effect of an electrical double layer within the fluid channel, the behavior of nanofluid is observed to be significantly different compared with its microfluidic counterparts. Its typical characteristic dimensions fall within the range of 1–100 nm. At least one dimension of the structure is in nanoscopic scale. Phenomena of fluids in nano-scale structure are discovered to be of different properties in electrochemistry and fluid dynamics.
