When it became clear that many structural steels show the increased tendency to local corrosion, research of reliable local corrosion protection methods and means demanded to concentrate the main attention on identification the role of geometrical factors and systems electrochemical parameters, in particular, electrochemical potential
of the corroding steel [3-5].
The electrochemical potential
and current noise were measured simultaneously by connecting two coated panels and Ag/AgCl reference electrode to the ECN port of the Autolab PGSTAT12.
The cathode and anode materials are selected to have a large electrochemical potential
between each other.

Lithium is the lightest metal element and has a high electrochemical potential
, giving lithium-ion (Li-ion) batteries a high specific energy and enabling them to function at higher voltages.
The lightest of all metals on the periodic table, this element's low density offers an outstanding ratio of electrochemical potential
* Lithium is the technology of choice for use in batteries because it has the highest electrochemical potential
. Lithium's weight and high energy power densities make it ideal for the commercial vehicle industry.
The large difference in electrochemical potential
between the nickel and gold causes corrosion of the nickel layer, while the gold acts as a powerful cathode.

The electrochemical flow-through surface plasmon resonance (SPR) instrument analyzes molecular binding processes and conformational changes of biomolecules under the influence of applied electrochemical potential
and controlled flow.

with the product of the valence of the ion times the Faraday (zF).
One goal, says Lindsay, is to develop a method for rapidly sequencing DNA bases using direct STM imaging of the DNA strands in solution under electrochemical potential
