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
In order to break through the structural limitation of 2D planar film and develop getter with large specific surface area (SSA), the 3D Ni-nanoarray based Ti–Zr–V film getter was prepared to effectively increase the SSA and finally improve its adsorption performance. The morphology and adsorption performance of Ti–Zr–V films deposited on Ni-based nano-scaffold and silicon substrate were studied by scanning electron microscopy, thermogravimetric analysis and hydrogen adsorption test. The gettering properties are found to be directly dependent on the deposited thickness of Ti–Zr–V film. The results show that the 80-nm-thick Ti–Zr–V film can maintain the porous structure of the original Ni nanoarrays and has the largest adsorption rate (1.274 × 10 −2 mg/(s·g)) and adsorption capacity (0.0587 mg) in the thermogravimetric analysis experiment. Under the same preparation and activation conditions, the H 2 adsorption rate and adsorption capacity of 3D Ni-nanoarray based Ti–Zr–V film are about three times and twice that of Ti–Zr–V film on silicon substrate, respectively. This is because the increase in SSA promotes the gas adsorption on the getter surface. The study indicates that the application of porous nanoarray as scaffold for getter film is an effective way to improve the adsorption performance.
