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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

ABSTRACT

The development of a molecular tagging fluorescence velocimetry (MTFV) system is discussed, and measurement results are presented for a meso-scale flow field of a thermally driven capillary pore of 5 mm inner diameter that is tilted 5° from the horizon. The technique uses caged dextran conjugates of caged fluorescence dyes of less than 10 nm in size for tracers. The frequency-tripled ultra violet (UV) band (l = 355 nm) of a pulsed neodymium-yttrium-aluminum-garnef (Nd:YAG) laser uncages the molecules by photo-cleaving—that is, decomposition of a caging and a fluorescence chemical group. Then a continuous wave (CW) blue argon ion laser (l = 488 n) pumps the fluorescence of only those uncaged molecules whose emission band is centered at l = 518 nm, and a sequential recording of the fluorescence images are digitally created and analyzed for Lagrangian velocity field mapping. The use of the technique allows detailed measurements of the thermally driven three-dimensional flow inside a heated capillary pore. The measurements show that the meniscus surface flow is mainly driven by the thermocapillary stress field, resulting from the surface temperature gradient, while the bulk flow inside the pore is driven largely by the natural convection buoyancy.
