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: 1.2 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: 1.8 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

要約

An experimental study has been conducted to analyze the characteristics of ultrasonic atomization when working with some alkanes and alcohols. Ultrasonic atomization is very convenient because it can generate droplets with diameters of a few microns, with very narrow size distribution, and at low velocity. To date, most of the published results have been limited to experiments with water. However, it has been demonstrated that atomization rates quickly decrease as liquid viscosity increases. To produce droplets of high viscosity liquids, first they can be diluted in volatile solvents with low viscosity, and then the mixture can be atomized afterward. To facilitate this possibility and advance the understanding of the dependence on different physical properties, this work analyzes the characteristics of ultrasonic atomization of some organic compounds commonly used as solvents. In particular, hexane, heptane, decane, methanol, ethanol, and 2-propanol were considered. A commercial piezoceramic disk with a resonance frequency of 1.65 MHz was used in the experiments, and the atomization rates were measured. The sprays were characterized by analyzing instantaneous images and high-speed video sequences and measuring droplet size distribution functions. The results confirm that the viscosity strongly conditions the atomization efficiency. The role of other fluid properties is more difficult to ascertain, but some experiments were performed to elucidate it.
