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
Layered transition metal dichalcogenide (TMD) materials possess novel and unique semiconducting properties when exfoliated into thin sheets or individual layers. The exfoliation leads to effective sensing towards gas molecule due to the increase in surface-active sites and edge zone disorders. In this work, we present exfoliation of bulk WS sheets with liquid-based dispersion technique using facile bath sonication method for NO molecule sensing. The exfoliated WS nanosheets show reversible and selective response towards NO gas molecules operating at room temperature. The sensitive film shows p-type characteristics providing sensor response rate around 27% for 10 ppm NO with rapid response and recovery time around 45 s and 60 s, respectively. The sensitive response was further studied at high temperature of 150 °C showing a drastic increase in response rate as 45% with effective response and recovery time. This improvement in NO gas sensing was attributed to the facile exfoliation of WS nanosheets.
