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

A kinetic mechanism of thermal decomposition of hydrogen azide (HN3) has been developed. The mechanism adequately describes experimental data on the self-ignition of HN3 and propagation velocity of HN3 flames available in the literature. The mechanism includes 60 reactions with 15 participating species (He, H2, H, N, NH, NH2, NNH, NH3, HN3, N3, N2, Ar, N2H2, N2H3, and N2H4). For the total pressure of 50 Torr of mixtures of HN3 with different diluents (N2, Ar, and He), self-ignition limits of HN3 and flame speeds were calculated using the developed mechanism. The results of modeling of the flame structure of the HN3/N2 and the HN3/Ar mixtures demonstrated that, with the HN3 concentration in the 50−100% range, the maximum temperatures in the flame front exceed thermodynamic equilibrium values by 140−610 K; i.e., super-adiabatic flame temperatures are reached. The developed mechanism can be used for modeling combustion and thermal decomposition in chemical systems containing hydrogen azide.
