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
Hydrogen sulfide (HS) is a highly poisonous gas; if present in a workplace, it must be identified immediately at concentrations greater than 10 ppm. Although there are numerous reports on sensing HS gas using various techniques and approaches, there still exists a gap in terms of the limit of detection (LOD) and feasibility. In this work, we demonstrated capacitive HS sensing for the first time using metal-organic frameworks (MOFs) decorated with silver oxide (AgO) nanoparticles as the sensing materials. The nanoparticles were deposited on three MOFs (UiO-66(Zr) BDC, UiO-66(Zr) BDC-NO, and UiO-66(Zr) BDC-N) using the impregnation technique. The sensing materials were characterized for morphology using X-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy techniques. The synthesized MOFs were coated on interdigitated electrode capacitors as the dielectric materials and a comparison of their sensing properties was presented; among them, UiO-66(Zr) BDC-NO loaded with AgO showed the highest sensitivity towards HS. The optimized MOF-AgO composite demonstrated experimental LOD of 1 ppm of HS at room temperature, showing high chemical absorption affinity towards HS. The work presented here is promising for developing sensitive HS sensors and in addition paves the way to explore and develop other possible MOF-based composite materials for gas sensing applications.
