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: 1.4 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: 1.3 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: 2.2 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: 0.00034 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: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

ABSTRACT

Molecular dynamics simulations were performed to investigate a eutectic mixture of Li2CO3-K2CO3 (62:38 by molar ratio) doped with SiO2 nanoparticles. Literature studies show one salt of the eutectic can form a needlelike nanostructure due to its interaction with a SiO2 nanoparticle. The formed nanostructure is known to enhance the specific heat of the mixture. Several experimental studies have shown the effect of the nanostructure on the effective specific heat of the mixture. However, no theoretical or computational studies have been reported to corroborate the experimental findings. In this study, a eutectic mixture of Li2CO3-K2CO3 was doped with several SiO2 nanoparticles and needle-like Li2CO3 nanostructures. The density and specific heat of the mixture was computed by molecular dynamics simulations. Results show that SiO2 nanoparticles have a minimal effect on the effective specific heat of the mixture, yet needlelike Li2CO3 nanostructures were shown to increase the effective specific heat of the mixture. In addition, multiple Li2CO3 nanostructures with a different size were used to understand the mechanism behind the enhanced effective specific heat.
