After five years, Elsevier has finally issued a notice of retraction for a paper it announced it was pulling for fraud in 2011.
All of the papers were produced by a research group in Brazil; all were retracted after the publisher conducted an investigation, concluding that the NMR results had been manipulated. At the time, the last author on the latest retraction, Claudio Airoldi, defended the work. Since then, however, Airoldi has logged two more retractions, bringing his total to 13.
According to an editor’s note, published in Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, the journal received confirmation from all three authors that the aforementioned researcher should be removed from the author list during proofing stage. However, the researcher whose name was omitted — Nahid Nishat of the Jamia Millia Islamia in Jamia Nagar, New Delhi, India — later contacted the journal claiming that she didn’t okay this move.
Nishat told Retraction Watch that she believes the two listed authors on the paper wrote to the journal on her behalf to remove her name: Read the rest of this entry »
Chem paper “the product of intentional, knowing, or reckless falsification, fabrication, and plagiarism”
According to the retraction notice in RSC Advances, the first author submitted the paper without the knowledge of the other two co-authors, and the paper was falsified, fabricated, and plagiarized. The notice cites a probe at the University of Tennessee (UT) at Knoxville — where all three listed authors are based — that concluded the study’s findings were invalid.
According to the EOC, published in RSC Advances, the paper is now under investigation.
Recently, François-Xavier Coudert, a researcher at the Research Institute of Chemistry of Paris in France, noticed something strange: A nearly perfect image in a chemistry paper, with none of the typically expected “noise.”
Last week, he started a thread on PubPeer, alerting readers to his concerns — namely, that a microscopy image showed hexagons with crisp edges. The author responded that the students had been working to obtain a “perfect hexagonal structure,” and had adjusted the contrast of the image to make it seamless. But, the author noted, the paper was being retracted for other reasons.
Indeed, a spokesperson for Elsevier, which publishes the Journal of Photochemistry and Photobiology B: Biology (JPB), has confirmed to us the paper will be retracted. Here’s the upcoming notice for “Influence of humic acid on the stability and bacterial toxicity of zinc oxide nanoparticles in water,” which cites image duplication as the reason: Read the rest of this entry »
According to the notice in Carbohydrate Polymers, the University of Calcutta in West Bengal, India, where the research was carried out, has “failed to provide evidence of a thorough, fair, and proper investigation of this claim,” despite being presented with evidence from both sides.
The study’s last and corresponding author told us that his former student, who had previously co-authored some abstracts, got in touch with journal, alleging to be an author of the present paper.
A U.S. Congressional subcommittee is investigating two cases of fraud affecting one Colorado lab run by the U.S. Geological Survey (USGS).
The misconduct occurred in two separate cases, taking place between 1998 and 2014. We covered the most recent incident, in which a chemist doctored data in up to 24 projects supported by more than $100 million in federal funding.
A letter from the Committee on Natural Resources’ Subcommittee on Oversight and Investigations to USGS director Suzette Kimball details another incident that took place in the Energy Resources Program (ERP) Geochemistry Laboratory in Lakewood, Colorado, in which another worker manipulated data for more than a decade.
The letter notes that, although the incidents were reviewed by the Department of the Interior (DOI) Scientific Integrity Review Panel and its Office of Inspector General (OIG): Read the rest of this entry »
According to the story, a bunch of painters took six 220-cubic foot gas cylinders off their off their wall supports and put them to the side to allow the painting of an area. A painter, who was trying to scoot one of the cylinder across the floor, realized that it was leaking gas. But before he could do anything, he found himself being jet-propelled across the construction site.
The amusing story has spread through safety circles and the academic literature, appearing in the Journal of Chemical Education, which is published by the American Chemical Society, in June 1976. But does the account contain any element of truth?
It turns out that’s quite unclear. Read the rest of this entry »
A researcher has pulled a paper about uranium oxide fuel pellets after notifying the journal the data had been falsified — and, what’s more, the publisher can’t verify the identities of the co-authors.
Originally, the Journal of the European Ceramic Society paper suggested a way to increase the compatibility of uranium oxide fuel pellets, which are usually used in nuclear reactors, at high temperatures.
The corresponding author of the study that detected toxic leaks from the work of prominent British artist Damien Hirst has now retracted it — but most of his co-authors disagree with the decision.
The April Analytical Methods study was covered extensively by the media when it suggested staff at Damien Hirst’s 2012 exhibition at Tate Gallery in London of dead animals embalmed in formaldehyde were being exposed to higher than recommended levels of the carcinogen.
Tate and Hirst’s company, Science Limited, immediately objected to the results; we’ve obtained what appears to be letter from a lawyer for Science Limited to the corresponding author of the paper — Pier Giorgio Righetti of the Polytechnic University of Milan in Italy — saying it was “deeply concerned and troubled by the claims” in the paper.
Last month, the journal issued an expression of concern (EOC) for the paper, nothing the data may not be reliable, and on July 15, Righetti announced in a joint statement with Hirst’s company that he will be retracting his study.
Now, the paper has been officially retracted, noting more recent measurements show formaldehyde levels to be much lower than originally reported. But most of Righetti’s co-authors disagree with the decision, the notice says: Read the rest of this entry »
