The journals of the American Chemical Society (ACS) recorded new levels of prominence in 2019, according to data reported on June 29 in the 2020 Web of Science Journal Citation ReportsTM (JCR) from Clarivate.
ACS’ journals grew in published output, impact and citations across the portfolio, reflecting their deep and enduring relevance across chemistry and related fields. Total citations increased to over 3.6 million, an almost 7% increase from the previous year. These citation gains represent a decade of continuous growth for ACS Publications, with the number of citations doubling in the past 10 years. As a result of the expanded citations, ACS journals remain the most impactful in five of the seven main chemistry categories: Chemistry, Analytical; Chemistry, Inorganic & Nuclear; Chemistry, Medicinal; Chemistry, Multidisciplinary; and Chemistry, Organic.
Notable highlights from this year’s JCR include ACS’ flagship multidisciplinary chemistry journal, the Journal of the American Chemical Society, which continued to strengthen its position as the most-cited journal in chemistry, tallying more than half-a-million citations in 2019, contributing to its Journal Impact FactorTM of 14.612. This strong performance continues to place it firmly above competitor journals, such as Wiley’s Angewandte Chemie International Edition. ACS journals lead in both the most citations and highest Journal Impact FactorTM in the multidisciplinary chemistry category; Chemical Reviews secured its leadership position as the highest impact chemistry journal with a Journal Impact FactorTM of 52.758.
ACS Applied Materials & Interfaces expanded in published articles, citations and impact for the fifth year in a row, with citations increasing by over 44,000. ACS Applied Energy Materials received an inaugural Journal Impact FactorTM of 4.473, encompassing only one year of published articles. ACS recently expanded its portfolio of journals to support additional applied materials research, and its growing strength and importance in the discipline is evident.
ACS’ environmental and sustainable chemistry portfolio led the field in impact and citations. ACS Sustainable Chemistry & Engineering increased its Journal Impact FactorTM to 7.632 while expanding citations by more than 65%. Environmental Science & Technology (ES&T) remained the most-cited journal in the “Engineering, Environmental” and “Environmental Science” categories, with a record Journal Impact FactorTM of 7.864 and a record 187,990 citations. Environmental Science & Technology Letters also earned its highest-ever Journal Impact FactorTM, 7.678, and its highest-ever citation count. ACS is expanding this portfolio through the introduction of ACS ES&T Water and ACS ES&T Engineering later this year.
Citations, Journal Impact FactorTM and published output grew in journals across the portfolio. ACS Catalysis received an Journal Impact FactorTM of 12.350 and 70,712 citations, an increase of 27% from 2018, and ACS Sensors received an Journal Impact FactorTM of 7.333 and 6,209 citations, an increase of more than 80%.
Topically focused journals saw increases in Journal Impact FactorTM, including ACS Energy Letters, a relatively new journal which has rapidly grown in influence since its founding. The journal’s Journal Impact FactorTM increased to 19.003, supported by over 18,000 citations, making it the highest impact journal in the “Electrochemistry” category and surpassing all competitors. ACS Nano received a Journal Impact FactorTM of 14.588, with over 166,000 total citations. The Journal of Chemical Information and Modeling received a Journal Impact FactorTM of 4.549 and 19,075 citations, while Biomacromolecules received a record high Journal Impact FactorTM of 6.092 and 38,863 total citations.
The Journal of Agricultural and Food Chemistry achieved 118,586 citations and is the most-cited journal in the category of “Agriculture, Multidisciplinary.” Many ACS journals dominated their category, including Analytical Chemistry, receiving the highest citations in the “Chemistry, Analytical” category; Inorganic Chemistry as the most-highly cited in “Chemistry, Inorganic & Nuclear;” the Journal of Medicinal Chemistry as the most-highly cited in “Chemistry, Medicinal;” Organic Letters as the most-highly cited in “Chemistry, Organic;” Crystal Growth & Design as the most-highly cited in “Crystallography;” and Macromolecules as the most-highly cited in the “Polymer Science” category.
Demand for open access publishing is growing. ACS Central Science, the premier venue for publishing exceptional interdisciplinary chemical research that is free to both authors and readers, also saw citations rise over 60%. ACS Omega reached a Journal Impact FactorTM of 2.870 and attracted more than 10,600 citations, close to a threefold increase from the prior year. Both journals continue to attract more global authors year on year.
