Scaling of Electrode-Electrolyte Interface Model Parameters In Phosphate Buffered Saline [PDF]

open access: yes, 2014
We report how the impedance presented by a platinum electrode scales with the concentration of phosphate buffered saline (PBS). We find that the constant phase element of the model scales with approximately the log of concentration, whereas the ...
