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

RÉSUMÉ

The thermal decomposition and reduction of Fe-oxalate to form pyrophoric iron particles were investigated. Decomposition and reduction experiments were performed in a tubular quartz reactor at 450−520°C under reducing environment of 5−50 vol% H2 and 95−50 vol% N2. Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) revealed that the decomposition of Fe-oxalate in an inert atmosphere is a two-step process involving the removal of water and decomposition of oxalate to iron oxides. In the presence of H2, the products of decomposition are reduced into α-Fe particles. The results have shown that Fe-particles generated from oxalate are pyrophoric in air and burn within 15−30 seconds with maximum temperatures generated in the range of 620−820°C. The effect of reduction temperature, H2 concentration, and sample geometry on pyrophoric behavior was also investigated. In other efforts, Fe-oxalate was synthesized from FeCl2.2H2O and its pyrophoric performance was compared with the commercial material.
