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
The influence of the presence of positively charged gel layers deposited on the electrode surface on reduction and oxidation of ionic substances in the absence of deliberately added supporting electrolyte was examined. The gel layers based on crosslinked copolymer of N-isopropylacrylamide (NIPA) and N-(3-aminopropyl)methacrylamide hydrochloride were used. The polymer net was positively charged in a wide pH range. Differently charged ferrocene derivatives, ferrocenyltrimethylammonium cation (FcN+), sodium salt of ferrocenylmethyl-3-mercapto-1-propanesulfonic acid (FcS−) and 1,1’-ferrocenedimethanol (Fc(MeOH) 2 ), were used as the electroactive probes. It appeared that the depression of the oxidation current of cations was much stronger compared to bare electrodes; the depression factor equaled circa 2. The increase in oxidation current of anions was also strongly enhanced compared to bare electrodes; it amounted to 1.7 times. Addition of excess supporting electrolyte to the solution led to cancelling of major current changes. It meant that sufficiently concentrated supporting electrolyte eliminated not only regular migrational contribution but also strongly influenced the electrostatic-interactions between charged probes and charged polymer network.
