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

Краткое описание

The chemical flame structure of cyclic nitramines (HMX, RDX) was investigated at a pressure of 0.1 MPa using molecular beam mass spectrometry. HMX and RDX strands were burned in air and argon atmosphere, respectively. It was obtained that at atmospheric pressure combustion of HMX (unlike to RDX) is unstable. Eleven species (H2, H2O, HCN, CO2, CO, N2, N2O, CH2O, NO, NO2 and nitramine vapor (HMX or RDX)) were found in flames of HMX and RDX during its self-sustained combustion at a pressure of 0.1 MPa. It was found that nitramine flame at a pressure of 0.1 MPa has a two-zone structure. In the first flame zone, the consumption of nitramine vapor (HMX or RDX), NO2, CH2O and partial consumption of N2O with formation of H2, H2O, CO, N2, CO2, HCN and NO occurs. In the second flame zone, the main reaction is oxidation of HCN by NO accompanied with formation of final combustion products. Using experimental data, brutto-reactions for the gasification of nitramines at atmospheric pressure were determined. Data obtained in this work can be used for further development of the mechanism of gas-phase chemical reactions occurring in RDX and HMX flames.
