The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RÉSUMÉ

Radio-frequency plasma synthesis of polynitrogen (PN) stabilized on single- and multiwall carbon nanotubes has been carried out using nitrogen mixed with argon or with hydrogen as precursors. Characterization of the samples produced was conducted by Raman spectroscopy (Raman), attenuated total reflectance−Fourier transform infrared spectroscopy, scanning (SEM) and transmission (TEM) electron microscopy, energy-dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy, and differential scanning calorimetry (DSC). Raman, SEM, and TEM showed that an amorphous PN phase is formed on the sidewalls and inside the carbon nanotubes (CNTs), which decomposes exothermally at approximately 300° C, as indicated by DSC measurements. Molecular modeling assessment of the energy performance was carried out for the related nitrogen chain N8 molecule hosted inside a CNT and combined with the double-base energetic material (nitrocellulose, nitroglycerin). Similar assessment was also carried out for a promising nitrogen-rich molecule, 3,6-di(hydrazino)-1,2,4,5-tetrazine (DHT), in its double-base form. The encapsulation of this system inside a nitrogen-doped CNT was considered for showing the effect of CNTs on energetic performance.
