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.

Article Description
In this work, hexadecyltrimethylammonium-bromide (HTAB)-modified polythiophene (PTh)/TiO nanocomposite (HTAB/PTh/TiO) was applied to remove uranyl ions (UO). FT-IR, XRD, ζ potential, TGA, SEM, and XPS were utilized to obtain the chemical and physical properties of HTAB/PTh/TiO. The effects of HTAB content, preparation temperature, and adsorption conditions on UO removal were investigated comprehensively. And the UO adsorption process on HTAB/PTh/TiO was fitted to the Sips model with a saturated adsorption capacity of 234.74 mg/g, which was 6 times over TiO. The results suggested that the surfactant of HTAB can significantly improve the adsorption ability of TiO for UO ions. This work provides a strategy of surfactant modification for enhancing the separation and recovery ability of adsorbent toward UO in the radioactive wastewater.
