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

Nanostructuring of materials is becoming increasingly important in all scientific and industrial fields. Explosives, priming formulations, propellants, whether used in small or in very large amounts, are fully concerned. Explosives, thermite mixtures, propellants, boosters, and their combinations were nanostructured to enhance the performances of existing micron-sized products, often in a disruptive way. Higher performance means higher combustion kinetics with enhanced power density, but also means the possibility of decreasing sensitivity without decreasing priming power. On the other hand, the use of nanomaterials allows designing smart energetic materials by adjusting the structures of these materials at nanoscale. For instance, the high potential of nanoengineering energetic materials has led to the development of hybrid energetic nanomaterials, which are promising candidates to replace primary explosives containing heavy metals. The future energetic materials used in systems such as explosive charges, detonators, or propellants will have a function "by design." They will have all at once higher performance and lower impact on the environment than conventional energetic materials. The advances in the field of nanomaterial continuous engineering now make it possible not only to design miniaturized detonating systems, but also to develop larger energetic charges and nanostructured propellants as the production capacity is increased thanks to up-scaled facilities. An example of the continuous nanostructuring method is the spray flash evaporation (SFE) process developed at NS3E laboratory to produce nanostructured energetic materials. This article describes this process and its use for preparing energetic nanomaterials such as explosives, oxidizers, and propellants in the state of submicron- to nanosized powders. It also deals with cutting-edge techniques, which are necessary to understand how SFE works and to characterize the composite nanoparticles prepared by this process.
