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

RESUMO

The reaction mechanism of catalytic decomposition of hydroxylammonium nitrate (HAN) aqueous solutions was investigated to understand the catalytic decomposition and to develop the thruster using a HAN-based monopropellant. It is important to understand the catalytic decomposition because the chemical reaction of the monopropellant is activated by a catalyst in the existing monopropellant thruster. Previously, several researchers investigated the thermal decomposition and the combustion characteristics of HAN-based solutions. However, catalytic decomposition of HAN-based monopropellant has not been well understood. In this study, in order to clarify the reaction mechanisms of catalytic and thermal decompositions, differential thermal analysis and thermogravimetric analysis of HAN aqueous solution and product gas analysis were conducted in the cases of catalytic and thermal decompositions. These analyses show that the Ir-based catalyst was effective to reduce the onset temperature of HAN decomposition and that the difference in product gas species was not obvious between catalytic and thermal decompositions. Based upon these results, a reaction mechanism of catalytic decomposition was discussed. It was found that the reaction mechanism of catalytic decomposition is almost the same as that of thermal decomposition. Furthermore, nitric acid (HNO3) was generated at lower temperature in the case of catalytic decomposition than that of thermal decomposition. Therefore, Ir-based catalyst cannot change the reaction mechanism but can activate the reaction path of HNO3 generation.
