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
Globally, fossil fuel combustion from various industrial processes has caused a significant increase in CO 2 emissions, exacerbating the greenhouse effect and climate change. Therefore, effective CO 2 capture technologies must be urgently developed. Vacuum temperature swing adsorption (VTSA) is an efficient technique for CO 2 capture. The presence of water vapor, H 2 S, etc., is an important factor that affects the performance of CO 2 adsorption, and they are usually removed prior to the adsorption separation process. However, volatile organic compounds (VOCs), a common component of industrial flue gas, can also affect the adsorption and capture of CO 2, which is often ignored. Thus, in this study, the effect of isopropanol (IPA), one of the most common VOCs used in industry, on the CO 2 removal performance is examined using an in-house VTSA device with activated carbon (AC) as the adsorbent. The effect of IPA on the CO 2 adsorption performance of AC under varying IPA concentration, IPA content in AC, feed flow rate, and adsorption/desorption temperature is comprehensively investigated. The results verify that the impact of VOCs in the industrial exhaust gases on CO 2 capture by adsorption cannot be disregarded.
