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
The structure of grafted chain layers immersed in an explicit solvent consisting of chain molecules is studied using density functional theory. We consider bonded layers built of short grafted chains at a moderate grafting density. We investigate the grafted layers in contact with oligomeric solvents and oligomer-monomer solutions. The chain molecules are freely jointed spherical segments. The substrate is assumed to be inert with respect to the grafted chains. The mobile molecules interact with the surface via Lennard-Jones (9-3) potential. The interactions between mobile chains, monomers, as well as segments of the tethered chains are described by Lennard-Jones (12-6) potential. We discuss how the structure of the grafted chain layer depends on the length of mobile chains and strengths of grafted chain-oligomer, oligomer-substrate, oligomer-oligomer, and oligomer-monomer interactions. We study the impact of mixture composition on the height of the bonded layer for selected model systems. The results are consistent with previous experimental and simulation data. © 2013 American Chemical Society.
