Metric Options: CountsSelecting 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 molybdenum oxide and graphene oxide (MoO /GO) nanocomposite has been fabricated via simple hydrothermal assisted synthesis using Mo and MoO as precursors. The MoO nanospheres with porous hollow structure are assembled onto GO nanosheets. Profiting from the plasmonic effects of MoO and synergistic effect of MoO and GO, this hybrid nanomaterial exhibits significantly enhanced surface enhanced Raman scattering (SERS) activity for organic pollutants. The detection limit for rhodamine 6G (R6G) is 1.0 × 10 M, and the maximum enhancement factor (EF) reaches up to 1.05 × 10 , which is the best among the semiconductor-based SERS materials. For practical application, the MoO /GO SERS substrates are also applied to detect Methylene blue (MB) in river water, and the detection limit (1.0 × 10 M) can be acquired. Pyrene is also chosen as probe molecule, and quantitative determination is achieved with detection limit of 1.0 × 10 M. These demonstrate the well feasibility for multi-molecule detection. Furthermore, the nanocomposite displays high stability, reproducible stability, and acid and alkali resistance.
