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
The rapid growth of electronics has resulted in significant electromagnetic interference and threatens the human biological system. As a result, producing lightweight, high-performance electromagnetic interference shielding materials is crucial to safeguard human and technological devices from exposure to electromagnetic interference. For the first time, Ba 1·8 Sr 0·2 Zn 2 Fe 11.9 Dy 0.1 O 22, CaTiO 3, Ti 3 C 2 Tx-MXene, and their composites were synthesized with superior shielding effectiveness in the X-band frequency range. This unique combination of magnetic, dielectric, and conducting components contributes to high total shielding effectiveness in their composites. The saturation magnetization, 35.36, emu/g 23.00 emu/g, 22.59 emu/g, and 11.79 emu/g obtained from the composites are essential for improving the shielding effectiveness. Ba 1.8 Sr 0.2 Zn 2 Fe 11.9 Dy 0.1 O 22 /Ti 3 C 2 T x -MXene (ratio 2:1) composite has a higher total shielding effectiveness of around −88.29 dB at 11.8 GHz frequency. Furthermore, this observed increased shielding effectiveness was attributed to an absorption-dominated shielding mechanism. This study reveals that the Ba 1·8 Sr 0·2 Zn 2 Fe 11.9 Dy 0.1 O 22 /CaTiO 3 /Ti 3 C 2 T x -MXene composite is a potential EMI shielding material.
