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

ABSTRACT

In this collaborative study on the hypergolic reaction of N2H4 with N2O4, we have kinetically modeled the temperature and pressure behaviors of the system upon mixing at high temperatures under the conditions employed by Sawyer and Glassman in 1967 and at low temperature in the gas phase as well as in N2H4 solution. The kinetics reported by Sawyer and Glassman using their adiabatic flow reactor study at 800−1000 K under atmospheric pressure measured with a thermocouple for temperature change, attributed to NO2 + N2H4 and NO + N2H4 reactions, could only be qualitatively accounted for by modeling with our full mechanism containing 41 species and 196 reactions. At 300 K, our modeling of the mixtures containing 16 Torr and 1 atm each of the reagents indicates that the hypergolic ignition resulted entirely from the NO2 + N2H4 → HONO + N2H3 reaction, whereas in the N2H4 solution, the bimolecular reaction of N2H4 with ONONO2 as proposed by Lai et al. in 2012 is responsible for the initiation reaction and the formation of the energetic hydrazinium nitrate (N2H5+NO3) salt which was detected previously in different condensed-phase reaction studies.
