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

ABSTRACT

This study investigated droplet-size spectra and aerosol production from consumer products dispensed by disposable trigger sprayers for deposition on household surfaces. A strategy was devised to reduce the generation of small, mobile droplets through nozzle selection and manipulation of fluid properties. Parametric experiments with a generic laundry stain remover ("prespotter"), five spray dispenser designs, and four concentrations of a long-chain polymer were conducted. Surface tension of the test formulations ranged from 0.0350 to 0.0365 N/m. Shear viscosities ranged from 258 to 165 cps (shear rate of 7.5 s−1) and 66 to 48 cps (shear rate of 75 s−1). Polymer concentrations ranged from 0.00% to 0.10% w/w. Elongational viscosity characteristics were measured using a modified flow technique modeled after R. W. Dexter [14]. Droplet size spectra of the spray discharged from dispensers were measured with a laser-diffraction system. Design of the trigger spray nozzle significantly affected the droplet size spectra. For all trigger sprayers studied, addition of polymer to the spray formulation significantly reduced the generation of aerosol droplets. Mass transfer studies confirmed that addition of polymer reduced airborne spray aerosols by 86% to 94%. Similarly, addition of the polymer reduced the generation of mobile aerosols from spray impaction on target surfaces by 47−98%, depending on nozzle design and target surface characteristics.
