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
A metal–organic framework (MOF)-derived porous metal oxide/graphene nanocomposite (FeMn-MOF/G) was first applied in anaerobic digestion (AD) to investigate the mitigation effect of ammonia nitrogen inhibition. Five total solids (TS) concentrations of 8%, 10%, 12%, 15% and 20% were set up for AD experiment. The results showed that the ammonia nitrogen adsorption capacity of FeMn-MOF/G in AD was 102.68 mg/g, and the concentration of ammonia nitrogen in AD was reduced to 2,086.00 mg/L. The methane production of the experimental group added FeMn-MOF/G increased significantly, reaching 321.35 mL/ gVS, which was 66.81% higher than that of the control group. The lowest VFAs concentration was 1,510.34 mg/L, indicating the successful operation of AD. The results of vibrating sample magnetometer show that FeMn-MOF/G has good superparamagnetism. Magnetic recovery is a potential method of FeMn-MOF/G material recovery. FeMn-MOF/G has broad application prospects in AD.
