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.

2023 JAN 17 (NewsRx) -- By a News Reporter-Staff News Editor at Tech Daily News -- Investigators publish new report on Technology - Carbon Research.
Article Description
We report for the first time that zinc oxide (ZnO) can not only effectively catalyze the conversion of acetylene into graphene, but also greatly lower the growth temperature to only 400 °C. With this method, super thin and defect rich graphene shell (TD-GS) is successfully prepared for the first time using ZnO nanoparticles as both the catalyst and template. The growth of TD-GS is tracked and monitored and its growth mechanism is illustrated. The as-prepared TD-GS exhibits remarkable performance as electrode material for applications in supercapacitors or novel catalyst support for oxygen reduction reaction. We also demonstrate that by simply adjusting the growth conditions or process, new carbon structures, like opened TD-GS, TD-GS aerogel and even graphene tube can be facilely realized.
