Metric Options: Counts1 Year3 YearSelecting 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 increasing use of pesticides has raised concerns about the risks of exposure to pesticides. Rapid, simple and sensitive detection of pesticides is still a challenge in the current analytical technology. Herein, a perfluorinated copper phthalocyanine (FCuPc) organic field-effect transistor (OFET) modified by β-cyclodextrin (β-CD) was used to detect boscalid molecules in solution. As a molecular carrier, β-CD will capture boscalid to form an inclusion complex. The hydroxyl group in β-CD and the carbonyl group in boscalid form a dipole-dipole interaction with FCuPc, which induces more carriers in the device channel, which finally manifests as a significant increase in the maximum current of the device. When using β-CD as the modification layer, the detection limit of the device can be as low as 2.40 × 10g L, which is 5 orders of magnitude lower than the internationally permitted MRL value.
