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 study, ultrafine ε-hexanitrohexaazaisowurtzitane (CL-20) particles were prepared by the high-pressure jet assisted precipitation method. The CL-20 samples were characterized by scanning electron microscopy (SEM), particle size analyzer, X-ray diffraction (XRD), and Fourier transformation infrared spectroscopy (FT-IR). Furthermore, the safety properties of samples under impact and thermal stimulus were tested and investigated. The results of SEM and particle size analysis indicate that ultrafine CL-20 particles, with a narrow particle size distribution, are about 300 nm in size and elliptical in shape. The XRD patterns and FT-IR spectra indicate that the polymorphic phase of ultrafine CL-20 particles are mainly ε-type. The differential scanning calorimetry results indicate that compared with those of raw CL-20, the exothermic decomposition peak temperature of ultrafine CL-20 decreases by about 5°C at different heating rates. The apparent activation energy of ultrafine CL-20 is about 10 kJ/mol higher than that of raw CL-20. However, the ultrafine samples have the lower thermal explosion critical temperature and higher decompose rate constant at 230° C. Compared with that of raw CL-20, the impact sensitivity of ultrafine CL-20 has been decreased significantly, for the drop height (H50) is increased from 12.8 to 32.1 cm.
