A chemistry database of crystal structures has marked nearly 1000 entries with expressions of concern after finding they were linked to articles identified as products of a paper mill. 

The Cambridge Crystallographic Data Centre (CCDC) added notes to 992 structures in its database, according to a notice posted to its website in May. And a crystallography researcher tells us the impact on the field could be significant.

The notes state:

A group of researchers in Japan who lost a paper earlier this spring in Science for misconduct have notched two more retractions, bringing their total to three. 

As we reported in April, Science pulled a 2020 article led by Masaya Sawamura, of Hokkaido University, in Sapporo, saying the authors discovered:

A Springer Nature journal has retracted a 2020 paper on exposure among cement workers to a potentially harmful chemical for a litany of errors that one might have expected peer reviewers to catch before publication – and the corresponding author is not happy.

Titled “Citrate stabilized Fe3O4/DMG modified carbon paste electrode for determination of octamethylcyclotetrasiloxane in blood plasma and urine samples of cement factory workers,” the article, which appeared in BMC Chemistry, was written by Rashid Heidarimoghadam and Abbas Farmany, of Hamadan University of Medical Sciences in Iran. 

Farmany, of Hamadan University of Medical Sciences in Iran, also happens to be a member of the journal’s editorial board, although he joined after the paper was accepted. 

According to the retraction notice:

A Nature journal has retracted a 2021 paper which made a bold claim about certain chemical reactions after several researchers raised questions about the analysis – but not before another group pulled their own article which built on the flawed findings. 

The first article, “The amine-catalysed Suzuki–Miyaura-type coupling of aryl halides and arylboronic acids,” appeared in Nature Catalysis in January. Most of the authors were affiliated with Hefei University of Technology, in China. The paper has been cited five times, according to Clarivate Analytics’ Web of Science. 

After publication, at least three groups of researchers published Matters Arising letters in the journal questioning the validity of the results, all of which appeared on December 2:

Journals published by the Royal Society of Chemistry have retracted four articles by a researcher in China for a range of misconduct, including manipulation of images, fabrication of authors and more. 

The papers were written by Rijun Gui, of Qingdao University and formerly of the School of Chemistry and Molecules Engineering at East China University of Science and Technology, in Shanghai, and published in 2013 and 2014. Gui has a sizable entry on PubPeer, where many of his studies have come under scrutiny for years. Together, the four papers have been cited nearly 150 times, according to Clarivate Analytics’ Web of Science.

It’s not quite Rashomon, but each of the retraction notices adds a bit of detail to the story.

A leading chemistry journal has retracted a 2019 paper by a pair of researchers in Switzerland after determining that it contained fabricated data. 

The article, “The manganese(I)‐catalyzed asymmetric transfer hydrogenation of ketones: disclosing the macrocylic privilege,” was written by Alessandro Passera and Antonio Mezzetti, of the ETH Zurich in Switzerland. It appeared in Angewandte Chemie International Edition.  

Readers might remember Angewandte Chemie from this post in June about a controversial article it published — and then removed — in the wake of a mass outcry that prompted much of its editorial board to resign and led to the suspension of two of its editors. Fallout from the scandal — in the form of “the journal’s interim Editor-in-Chief Committee” — is evident in the retraction notice, which reads:

Facing a storm of criticism on social media, a chemistry journal in Germany has suspended two editors who handled a controversial essay that it said “highlights the bias displayed in our field and many others” to women and minority researchers.

And the 16 members of the journal’s international advisory board — which includes Nobel Laureates — resigned while denouncing the essay.

The article, “Organic synthesis-where now?’ Is thirty years old. A reflection on the current state of affairs,” by Tomas Hudlicky, of Brock University in St. Catharines, Ontario, had appeared in Angewandte Chemie, the flagship publication of the German Chemical Society. Hudlicky’s argument included several statements that suggested a hostility to efforts on university campuses to promote diversity.

The journal initially removed the essay without a notice, which isn’t best practice for retractions. It has since issued this statement from Neville Compton, the editor-in-chief:

The New York Times isn’t the only outlet that has walked back a commentary this week amid reader outrage. 

Following a flood of criticism on social media, a chemistry journal in Germany has disappeared an essay by Canadian researcher who argued that efforts to promote diversity in the field were hurting science. [See an update on this post.]

A pair of researchers in India have lost a 2017 paper published by the UK’s Royal Society of Chemistry after an inquiry found that they’d stolen the guts of the work from an unpublished manuscript one of them had reviewed for another journal. 

The article in question, “Tri-s-triazine (s-heptazine), a novel electron-deficient core for soft self-assembled supramolecular structures,” appeared in Chemical Communications was submitted on August 4, 2017 and published on September 25, 2017, and was written by Irla Kumar and Sandeep Kumar, of the Raman Research Institute in Bangalore.

Sandeep Kumar, who is now retired, was a leading figure in the field of  liquid crystals. The Royal Society of Chemistry feted him as one of the “most cited” researchers in Chemical Communications and another of its journals in 2006 and 2007. He also served on the editorial boards of several journals, including Liquid Crystals — a post that is particularly relevant in light of what follows. 

According to the retraction notice:
