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

Catalytic activity of SnO2 nanocrystals with different percentages of the exposed [221] facets for the thermal decomposition of Cyclotrimethylenetrinitramine (RDX) was investigated. An enhancement in the catalytic activity was observed for the SnO2 nanocrystals with a higher percentage of the exposed [221] facets, in which the activation energy (Ea) of RDX decomposition was lowered from 172.6 to 125.5 kJ/mol, for octahedral SnO2 with over 90% of the exposed [221] facets. Theoretically evidenced by density functional theory calculations, such highly exposed [221] facets can be favorable for the adsorption and diffusion of NO2, and also facilitate the formation of active oxygen which can lead to the oxidation reaction of HCHO more completely in the catalytic decomposition of RDX. The effect of octahedral SnO2 on the combustion of solid rocket propellant was also investigated, which increased the burning rate of propellant strands by 30%. More important, typical fast-burning propellants are unstable due to oversensitivity to pressure variations, but the octahedral SnO2 yielded propellants with high yet stable burning rates over a broad pressure range.
