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

RESUMO

In this study, the effect of piezoelectricity on the sensitivity to ignition by laser radiation of 10% wt nanoaluminum/poly(vinylidene fluoride-trifluoroethylene) [nAl/P(VDF-TrFE)] composite films was investigated. Nanoaluminum particles were dispersed in P(VDF-TrFE) copolymer solution and cast into ~ 45 μm thick films. Ignition samples across which an electric field of 25 kV/mm could be applied were created by sputter coating gold electrodes on opposing sides of the film. Electrodes were coated on one side with a layer of carbon paint to absorb laser radiation. Samples were tested under four conditions: unmodified, unpoled with an applied electric field, poled without an electric field, and poled with an electric field. Results from this study indicate that both the application of an electric field and the activation of the piezoelectric properties of PVDF sensitize the composite as measured by a decrease in a mean time to ignition, with piezoelectricity activation sensitizing the composite to a greater degree than only an applied electric field.
