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
In the present work, bare nickel molybdate (NiMoO) and polyaniline enfolded nickel molybdate (NiMoO/PANI) nanocomposite hybrid electrode materials were prepared by sonochemical and in situ oxidative polymerization techniques, respectively. The phase formation, microstructure and surface morphology of all the freshly prepared bare and hybrid nanocomposite samples were analyzed by X-ray diffraction (XRD), Fourier transform infrared (FTIR), confocal Raman spectroscopy, High-resolution transmission electron microscopy (HR-TEM) and Atomic force microscopy (AFM) studies, respectively. XRD characterization confirmed that the polyaniline polymer does not hinder the crystallization of the NiMoO nanocrystals. Fourier transform infrared spectra and confocal Raman spectra were indicating that the NiMoO/PANI nanocomposite was successfully prepared. The electrochemical performances of bare NiMoO nanocrystals and NiMoO/polyaniline nanocomposite electrodes were investigated through cyclic voltammetry (CV), chronopotentiometry (CP) and cyclic stability studies. The observed results demonstrated that the newly prepared NiMoO/polyaniline nanocomposite electrode exhibits higher specific capacitance of 285 Fg and good cyclic stability of 92% retention even after 500 cycles than that of bare NiMoO nanocrystals. Thus, the NiMoO/PANI nanocomposite could be a promising electrode for supercapacitor applications.
