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: 0.4 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: 0.00005 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: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

RESUMO

Due to their exceptional properties, large amounts of single-walled carbon nanotubes (SWCNTs) have been increasingly used in a wide range of applications, and consequently, the economical production of high quality SWCNT is becoming a matter of major concerns. For this reason, carbon black is getting increasingly popular as a carbon source in SWCNT productions, principally because of its relatively low-cost and good market availability [ 1,2]. In this work, SWCNTs have been synthesized using eight different grades of carbon blacks in order to investigate the effects of the carbon black structure and its impurity content, on the SWCNT formation, when utilized in the newly developed RF induction thermal plasma process [2]. In the synthesis experiment, the SWCNTs are produced by the direct evaporation of a mixture of carbon black and catalysts (i.e., a ternary mixture consisting of Ni, Co, and Y2O3) inside the plasma plume [2]. The properties of the raw materials and products have been studied by the means of many characterization techniques such as, X-ray diffraction and Raman spectroscopy. Thermodynamic equilibrium compositions of the mixture of the carbon black and the catalysts used as a feedstock were also calculated theoretically to obtain a better understanding of the effects of carbon black grades on SWCNT production. Both the experimental and theoretical results show that the physico-chemical properties of the carbon blacks such as particle size, sulphur content, and grain size, all have significant effects on the quality of the SWCNT produced. However, they seem to have a negligible effect on the diameter distribution of the SWCNT.
