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
Prospective solid adsorbents for CO capture require low total regeneration energy that can be achieved by combining high working capacity, a low desorption temperature, and a narrow temperature difference (ΔT) between capture and regeneration. These materials should be critically water-stable because flue gas from coal-fired power plants contains water vapor. Herein, we present the development of a diamine-appended metal-organic framework (MOF) adsorbent that showed unprecedented performance with a record narrow ΔT (30 °C), a quite low regeneration temperature (≤100 °C), and a significant working capacity (14 wt%) over 600 cycles. Remarkably, coating of the MOF with polydimethylsiloxane (PDMS) imparted enhanced moisture stability and superior CO adsorption capacity. Such a simple coating approach can be used to design humidity-stable MOF adsorbents, with exceptional performance, applicable in real-world CO capture processes.
