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.

The properties of capillary columns with sorbents based on poly-(1-trimethylsilyl-1-propyne) modified with nitrous oxide.
Authors: Yuri V Patrushev, Elena Y Yakovleva, Inna K Shundrina, Dmitry P Ivanov, Tatyana S Glazneva PMID: 26105779 DOI: 10.1016/j.chroma.2015.06.013 Publication Type: Research Support, Non-U.S.
Article Description
In this work, we report the study of properties of capillary columns with a porous layer of the functionalized polymer prepared via oxidation of poly-(1-trimethylsilyl-1-propyne) (PTMSP) by nitrous oxide. It was shown that the double C C bonds of polymer reacted with nitrous oxide with formation of ketone, carbonyl and hydroxyl groups. The increase in number of those groups in polymer changed a polarity of PTMSP. The change in polarity of polymer led to the selectivity of separations, including oxygen-containing substances. The polarity values were calculated for the prepared columns. It was shown that the total polarity according to McReynolds (Δ I ) was lower than that for known porous polymers. The examples of separations of aliphatic and aromatic hydrocarbons, oxygen- and halogen-containing substances were presented.
