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
Diatoms are known to grow elaborate nano- and microstructured silica shells by depositing material from precursor-containing vesicles at mild temperature and pH. Oligo(1-methylazetane) and related moieties, in some cases attached to proteins, are believed to facilitate this process. To complement prior studies of more complex amines, we aim to understand why such a unique structure has evolved through a systematic study of a set of simple model compounds. The degree to which a series of diamines in solution enhances condensation of phosphate-buffered silicic acid at neutral pH increases with increasing alkylation, a factor more important than amine pKa. This suggests why diatoms often use methylated oligomers. Bis(quaternary ammonium) salts result in even greater reactivity enhancement, constituting a new class of compounds that promote condensation under mild conditions. Methods are presented for incorporation of these new moieties into artificial peptides or other template-forming molecules, which should allow for more effective production of tailored silica nanostructures. © The Royal Society of Chemistry.
