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

The preparation of new homogeneous and heterogeneous solid propellant formulations based on the new interesting high-energy dense oxidizer 2,2,2-trinitroethyl-formate (TNEF) and different kinds of binders (nitrocellulose, hydroxyl-terminated polybutadiene, and glycidyl azide polymer) are reported. The prepared TNEF was characterized by Fourier-transform infrared spectroscopy and nuclear magnetic resonance. The thermal investigation using non-isothermal differential scanning calorimetry and thermogravimetric analysis showed high thermal stability. TNEF has a decomposition temperature of ~ 210°C. The high density of TNEF (1.81 g/cm3 at 298 K) gives the propellant high loading density in the rocket motor. The Kissinger model-free method was used to determine the kinetic parameters of the studied samples. It was concluded that the new propellant formulations are a safe manufacturing process and have green (chlorine-free) gaseous products and higher activation energy than the common traditional formulations.
