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

RÉSUMÉ

In this article we report the developments and improvements in our ultrasound-assisted spray deposition system for polymer thin films and potentially nanoparticle-based coatings, organic device printing. Specifically, we focus on the development of a homogenous microstructure and uniform thickness of elastomeric thermoplastic polyurethane films. All film specimens have been obtained between 4 and 16 μm. We have devised and implemented a low-pressure concentric air-draft attachment with our existing setup to achieve this goal. We have schematically suggested a possible mechanism for the evolution of the spray during the deposition process. This mechanism is one where the spray core is dragged or pulled in the direction of the eight draft tubes. Varying the air pressure changes the width and shape of the spray. These visual observations have been schematically reported. Varying the liquid-to-air ratio between 25 and 150 μL/min varied the droplet numbers (a few to several hundreds) and diameters (130 μm to > 650 μm), indicating that coalescence can be controlled. Optical microscopy of our fully developed thin films (2, 6, and 10 layers) revealed a range of droplet diameters between 80 and 200 μm. This indicated that the deposition system was precise and quantified a reduction in the time and effort involved in fabricating these films (relative to not using a draft for the same process).
