“…The film capacitance ( C f ) and the double-layer capacitance ( C dl ) were calculated by eqs and C f = Y f R f 1 − n normalf n f C d l = Y d l false( bold-italicR bolds bold-italicR normalct bold-italicR bolds + bold-italicR normalct false) 1 − n dl n dl where Y is the modulus of CPE, the exponent n (−1 ≤ n ≤ 1) is associated with the distribution of time constant, and f and dl subscripts represent the surface film and electrochemical double layer, respectively.…”

“…The value of χ represents the chi-squared between the experimental data and fitting data, lower than 1%, suggesting a satisfactory fitting level. The η EIS values were obtained from the polarization resistance ( R p ) related to eq : , η EIS = true( 1 − R normalp normalo R normalp normall true) × 100 where R normalp normalo and R normalp normall are the tested solution polarization resistances without and with Cys-GO, respectively.…”

“…The value of χ represents the chisquared between the experimental data and fitting data, lower than 1%, suggesting a satisfactory fitting level. The η EIS values were obtained from the polarization resistance (R p ) related to eq 6: 50,51 where R p o and R p l are the tested solution polarization resistances without and with Cys-GO, respectively. Some important parameters evolved from EIS data are summarized in Table 3.…”
