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
Acid-base properties and support effects are known to be instrumental in the formation of methyl methacrylate (MMA) upon the aldol condensation involving formaldehyde (FA) and methyl propionate (MP). In this work, four different alumina-supported Cs-Nb catalysts were fabricated and employed for the aldol condensation of FA and MP. It was noticed that Al 2 O 3 -B prepared by co-precipitation exhibited superior catalytic activity on account of its highest surface area and porosity as well as the highest content of Brønsted acid and five-coordinated Al. The comparison of integration manner revealed that closer proximity affords keener synergetic interaction, thereby multiplying catalytic performance. Furthermore, the association from acid-base characteristics to catalytic activity was established. Strikingly, the cutting-edge 10Cs-10Nb-Al 2 O 3 -B catalyst presented a single-pass lifetime of 150 h. The rational synergism in favor of lessening the energetic barriers for the processes of enolization and C–C bond formation was further verified by DFT calculations.
