Hot Topics in Materials Chemistry and the Immediacy Index LongTerm versus Short-Term Impact
T
hanks to the immense quantity of data available through Web of Science and Google Scholar, one can spend hours combing through journal statistics. As one example of the flavor of data available, Google Scholar ranks English language journals from all disciplines, and we were pleased to note that Chemistry of Materials was included in their list of the top 100 publications (99th, just behind the Journal of Finance).1 The rankings were based upon the h5-index, which is the h-index calculated using citations of journal articles published within the last 5 years. Chemistry of Materials published 107 papers that were cited 107 times or more, during the period from June 2009 to June 2014. The h5-index looks at a substantially longer period of time than the regular impact factor (IF), which is based upon the citations of the journal generated from papers within the 2 years prior, in the year examined, i.e., 2014. With respect to short-term impact, the Web of Science and its accompanying Journal Citation Reports provide an immediacy index, which indicates how quickly articles in a journal are cited:
3. Large-Scale Production of Size-Controlled MoS2 Nanosheets by Shear Exfoliation,5 ASAP 4. The Art of Writing the Title of Your Paper,6 published June 10, 2014 5. Challenges for Rechargeable Li Batteries,7 published August 28, 2009 6. Vertically Aligned Carbon Nanotubes on Carbon Nanofibers: A Hierarchical Three-Dimensional Carbon Nanostructure for High-Energy Flexible Supercapacitors,8 ASAP 7. Anchoring Cobalt Nanocrystals through the Plane of Graphene: Highly Integrated Electrocatalyst for Oxygen Reduction Reaction,9 published December 23, 2014 8. Interface Engineering of Perovskite Hybrid Solar Cells with Solution-Processed Perylene−Diimide Heterojunctions toward High Performance,10 published December 8, 2014 9. Controlled Synthesis of Nitrogen-Doped Graphene from a Heteroatom Polymer and Its Mechanism of Formation,11 ASAP 10. Titles and Table of Contents Images: The Candy Store Analogy,12 published February 11, 2014 As can be seen, topics related to energy generation and storage are obviously of great interest, with 5 out of 10 clearly connected to this area of research, and possibly 7 out of 10 if the papers on MoS2 sheets (#3) and nitrogen-doped graphene (#9), due to their potential applications in the area of photocatalysis/solar fuels, are included. Interestingly, John Goodenough and Youngsik Kim’s 2009 review (#5) on rechargeable lithium batteries shows incredible staying power, due to its clarity in defining the challenges of the field in a manner delineating constructive pathways for discoveries. To contrast, from a fundamental perspective, an exploratory paper on the topic of new materials discovery (materials cartography) is our second most highly downloaded paper. Chemistry of Materials is, by definition, a journal of breadth and diversity, and as hot areas shift and evolve, essential insights into the chemistry of materials are long lasting and, hence, timeless. We believe that creative, high quality work will stand the test of time and can be applied broadly, regardless of the area in which it is initially published.
Immediacy index for 2014 # of citations of articles published in 2014 = # of articles published in 2014
Using Web of Science data, we noted that the immediacy index for Chemistry of Materials has gone up substantially, to a highly competitive 1.93 for 2014 (1698 citations/878 publications), from 1.27 for 2013 (783 citations/617 publications) and 1.12 for 2012 (663 citations/589 publications). We believe that we may be locating the sweet spot of timely (hot) papers, as demonstrated by the rapid increase in our immediacy index, while building long-term scientific value to the materials community through the publication of top quality manuscripts, as suggested by our high h5-index.
Using Web of Science data, we noted that the immediacy index for Chemistry of Materials has gone up substantially, to a highly competitive 1.93 for 2014.
