A Caltech researcher who shared the 2018 Nobel Prize in Chemistry has retracted a 2019 paper after being unable to replicate the results.
Frances Arnold, who won half of the 2018 prize for her work on the evolution of enzymes, tweeted the news earlier today:
Saudi researchers have lost a pair of papers in a spectrometry journal for errors the editors found fatal but the authors apparently dismiss as trivial.
The articles appeared in the Journal of Analytical Atomic Spectrometry, published by the Royal Society of Chemistry in the United Kingdom. The principal author on both papers is Mohammad Gondal, of the King Fahd University of Petroleum and Minerals in Dharhan. According to his website, Gondal is a highly decorated physicist, with

In May of this year, François-Xavier Coudert, a chemist at PSL University in Paris, had a question about a paper in Chemistry: A European Journal.
Several days later, he had an answer — sort of — along with an apology for readers from Haymo Ross, the journal’s editor in chief.

God giveth miracles … and it seems she taketh them away as well.
A group of chemists in China has lost a 2018 paper which described a “miraculous” discovery that wasn’t.
The paper was titled “A miraculous chiral Ir–Rh bimetallic nanocatalyst for asymmetric hydrogenation of activated ketones,” and it appeared in Organic Chemistry Frontiers, a publication of the Royal Society of Chemistry.
The authors, from the State Key Laboratory of Fine Chemicals at Dalian University of Technology, purported to show that:

A chemistry researcher in India is up to seven retractions and one correction for problematic images and other issues.
The researcher, Mahendra Yadav, was the first author on an article titled “Corrosion inhibition of tubing steel during acidization of oil and gas wells,” which appeared in 2013 in the Journal of Petroleum Engineering (JPE). Yadav, who also has a correction for similar concerns, and who has a fairly extensive entry in PubPeer, is listed as being affiliated with the Department of Applied Chemistry at the Indian School of Mines, in Dhanbad.
According to the notice:

The University of Texas (UT) at Austin does not have the authority to revoke degrees, a Texas judge ruled yesterday in a case involving a chemist whom the university alleges committed misconduct.
UT revoked Suvi Orr’s PhD in 2014, two years after the retraction of a paper that made up part of her thesis because, according to the retraction notice, some of the study was not reproducible. The university told Orr — who earned her PhD in 2008 and is now a researcher at Pfizer — that “scientific misconduct occurred in the production of your dissertation,” according to a letter to Orr from Judith Langlois, senior vice provost and dean of graduate studies.
Orr sued UT, which reversed its decision but then tried to again revoke her degree, at which point she sued again, this time also requesting the university cover her legal expenses. Orr alleges in the suit that she was being used as a “sacrificial lamb” to protect her former advisor, who she said made the errors in the paper.

The UK’s Royal Society of Chemistry has retracted a 2017 paper in one of its journals after learning that the authors stole the article from other researchers during peer review.
The offending article, “Typical and interstratified arrangements in Zn/Al layered double hydroxides: an experimental and theoretical approach,” appeared in CrystalEngComm, and was written by Priyadarshi Roy Chowdhury and Krishna G. Bhattacharyya, of Gauhati University in Jalukbari.
Well, that’s not really true, is it? The retraction notice lays out the transgression in detail: Continue reading Chem journal yanks paper because authors had stolen it as peer reviewers
Last year, chemist Marcus Tius at the University of Hawaii saw a paper describing the synthesis of some organic compounds, and was “struck by the implausibility” of the reported structures. So he joined up with some colleagues to try to replicate the data.
While Tius and his team were trying to repeat the experiment, however, in December 2017 the journal — Organic Letters — retracted the paper. The journal, published by the American Chemical Society, noted that the authors had not been able to produce crystal structures that confirm they had synthesized those compounds in particular. So Tius and his colleagues knew they couldn’t replicate the findings — but carried on their experiment anyway:
Decades ago, unbeknownst to each other, two chemists were independently working on a screening approach to identify new potential drugs. Both published papers about the technique around the same time. So now, when scientists write papers that cite the technique, who should get credit for discovering it?
Decades later, that question still hasn’t been answered — and the researchers continue to argue, this time over one’s decision not to cite the other’s work.
More than 30 years ago, Árpád Furka—now retired from Eötvös Loránd University in Budapest—developed an approach he says has had “outstanding importance” in drug development. The technique, called split-mix synthesis, made it possible to synthesize and screen millions of peptides at once, instead of one by one. Furka patented the method in 1982, presented an abstract in 1988, and published a paper in 1991. Continue reading Chemists duke it out over who was first to discover a 30-year-old technique
A researcher whose work on the use of nanomaterials has been heavily scrutinized on PubPeer — with one critic alleging a paper contained “obviously fabricated” images — has lost eight papers. [Editor’s note: See update below.]
The eight articles — seven from Biosensors and Bioelectronics and one from Analytica Chimica Acta, both published by Elsevier — all cite issues related to duplications, and conclude with some version of the following:
