Experimental and numerical characterization of an electrode-matrix cell for electrochemical measurements

Cation‐mediated electrostatic interaction in collagen–integrin complex

“…For each triangular patch, we approximate the unknowns (Φ m , Φ s ) by interpolating the nodal values with linear shape functions. The BEM discretization procedure is detailed elsewhere …”

Traceability of electrolytic conductivity measurements to the International System of Units in the sub mSm−1 region and review of models of electrolytic conductivity cells

“…A possibility is to insert the bipoles representing double layer effects in series with the solution resistance, as proposed in [40,42]. In comparison to the equivalent electric circuit based on the simple parallel of R S and C G , this model enables also the estimation of the low cut-off frequency f low , which results inversely proportional to the product of the solution resistance and the global double layer capacitance.…”

“…• analytical models obtained for simple cell geometries and accounting for the accumulation of ions at the electrodes by means of the Stern model [57]; • coupled models, based on the numerical or analytical determination of electrolyte resistance and electrode capacitance and on the successive inclusion of the double layer capacitance according to the Gouy-Chapman-Stern model [40,42]; • analytical or numerical models, which incorporate the contributions of polarisation and finite ion size following modified Poisson-Boltzmann theories [19,56,[58][59][60].…”

“…Although there is a lot of theoretical work on the electrode/solution interaction within a conductivity cell (e.g., [11,19,39,40] and references therein), until now no agreed model has been established, which enables the unambiguous deduction of the solution bulk resistance from measured impedance spectra. In the models that underlie conductivity measurements the bulk resistance is derived from an extrapolation of impedance data, after the virtual elimination of the parasitic terms due to interfacial polarisation and adsorption/desorption phenomena, which are prevalent in the low-frequency range.…”

Application of the thin‐shell formulation to the numerical modeling of Stern layer in biomolecular electrostatics

“…An example is represented by the low frequency behavior of the electrical impedance of electrochemical cells and their transient response, which are strongly influenced by the presence of the ion‐exclusion layer. [ 24–26 ]…”
