Metric Options: CountsSelecting 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
Development of the high energy storage with controlled way of releases is always desirable but challenging. Herein, a novel design of energy-storage system based on aluminum has been demonstrated with improved energy content. This group of hybrid materials uses energetic metal–organic frameworks (EMOFs) as the precursors of the metal oxides as the oxidizers in conventional nanothermites. These metastable nanocomposites of energetic MOF-activated Al (n-Al@EMOFs) are able to undergo self-sustainable combustion with multi-level energy releases. The resulted n-Al@EMOFs show unique two-step exothermic processes with a total heat release of as highly as 4142 J g −1, which is much higher than that of conventional Al/CuO system. In addition, the strategy could also help to reduce the high susceptibility of n-Al to surface oxidation and lower the ignition temperature of the composites (301.5 °C).
