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
Water pollution is one of the most urgent challenges of the 21st century, with water security having widespread consequences on society and the global economy. Methylene blue (MB) is a toxic by-product of textile and dye industries which has polluted wastewaters. Biofouling of man-made surfaces is a longstanding issue with serious consequences in the maritime and water treatment industries. Ag and its compounds are historically well-known as antibacterial agents, whilst polyethyleneimine (PEI) has good stabilizing and adsorption properties. In this work, colloidal Ag nanomaterials (diameter ∼2.6 ± 1.1 nm) produced using PEI as the capping agent demonstrated potential as antifouling photocatalysts for water treatment applications. The photocatalytic effect of Ag-PEI was studied using UV-visible spectrophotometry on the decomposition of methylene blue, with a 90.2% peak reduction of its UV-visible spectral peaks and decoloration recorded after 90 minutes of UV-irradiation. Separately, Ag-PEI demonstrated a 63% reduction of biofilm formation by Halomonas pacifica, a model marine-biofilm bacterium, through a static biofilm assay.
