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 possibility of N island formation during the conversion of NO + CO mixtures on Rh(111) and the kinetics observed in thermal desorption experiments from this system were studied by kinetic Monte Carlo simulations. Three models were proposed and tested to account for the behavior observed: (a) one where the free formation of islands through N diffusion on the surface is combined with nearest-neighbor (NN) attractive and repulsive second- and third-order neighbor interactions. (b) A second where compact islands with size similar to that suggested by experiments are produced by an alternative mechanism such as a preferential NO dissociation rate in the presence of an already dissociated N atom. In this model, thermal desorption is still assumed to be affected by adsorbate-adsorbate interactions as in model a. (c) A third where the nitrogen islands are formed as a result of adsorbate-substrate rather than adsorbate-adsorbate interactions, that is, where a "surface stress" mechanism is operative, and the same interactions affect the thermal desorption process. It was found that the experimental data can only be satisfactorily reproduced by model c. © 2007 American Chemical Society.
