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
Various compositions and structural motifs of bimetallic AuM (M = Ni and Ag) nanoalloy particles were investigated systematically in terms of structural, energetic, electronic, and stability properties by using the Density Functional Theory based ab initio approach. This method is used for exploring the properties of nanosized materials at the atomic/nano level. Synergetic effects were found on bimetallic AuNi and AuAg and NO 2 adsorbed AuNi structures. The studied bimetallic nanoparticles/clusters may be superior to their monometallic ones and that it may be possible to tune the bimetallic nanoparticles/clusters to obtain better performance. Results indicate that the AuNi clusters support the dissociation of NO 2 as NO + O, which provides a possible dissociation mechanism for the NO 2 conversion into harmless substances. This may be important for reducing environmental pollution. Furthermore, the STM calculations were made for a comparison of future STM and AFM experiments.
