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

摘要

The reactions of electropositive metals, such as aluminum, with water have long been utilized in explosive and propellant formulations, but until recently this has mostly been limited to the water formed as a product gas from the decomposition of another energetic system. Recently, however, with the increased availability of nanoparticulate materials, the direct reaction of nanoaluminum (nAl) with water as an oxidizer has been investigated as a propellant system due to high reaction temperatures and the production of hydrogen as the primary gaseous species. This system could be useful for intraplanetary travel where nonterrestrial water is harvested for the oxidizer. In this paper we study the merits of highly water soluble metal complexes of bis(tetrazolato)amine (MBTA) as burning rate modifiers for the nAl−water propellant system. Rates and pressure sensitivities are determined for stoichiometric nAl−water mixtures containing the complexes of iron, cobalt, and nickel and are compared with previously reported values from the unmodified system. The FeBTA at a loading of 15 wt% gave the highest burning rate enhancement (4.6× at ~6.8 MPa), while retaining a low pressure exponent (0.21 compared to 0.24 for nAl/H2O). At 15 wt% the Ni and Co increased the burning rate, but also increased the pressure exponents.
