Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Polymer-coated electrodes are widely used for the detection and oxidation of hydrogen peroxide (HO). Conducting polyaniline (PANI), poly (2-hydroxyanilne) (PHA), and their copolymer poly(aniline-co-2-hydroxyaniline) (PACHA) were electrochemically synthesized on a gold substrate for HO detection and analysis. Cyclic voltammetry (CV), square wave voltammetry (SWV), and differential pulse voltammetry (DPV) techniques were used for electroanalysis. Both PACHA and PANI greatly reduced the gold overpotential for HO oxidation with enhanced current densities. The PACHA-and PANI-coated electrodes showed oxidative peaks at 0.30 and 0.50 V, respectively, in the presence of 1.4 × 10 M HO, while PHA-coated electrodes exhibited no response. The fabricated electrodes displayed a linear response towards HO in range of 2 × 10 to 1.4 × 10 M, with very low detection limits (LODs) of 1 × 10 M (for PACHA) and 1.15 × 10 M (for PANI) evaluated from CV data. In case of SWV and DPV, the LODs were found to be 1.78 × 10 M (for PACHA) and 1 × 10 M (for PANI), respectively. The materials exhibit high sensitivity of 650 A/Mcm and show good stability. The PACHA-coated electrode shows better capacitance (1.84 × 10 F) than PHA-(2.52 × 10 F) and PANI-coated (1.17 × 10 F) electrodes.
