Can you explain what these 1,500 papers are doing in this journal?

James Heathers


The Internet of Things. Computer science. Botany. COVID-19.

All worthwhile subjects, to be sure. But what do they have to do with materials science?

That’s what James Heathers, who will be familiar to readers of Retraction Watch as a “data thug,” found himself wondering after he spent a weekend looking into articles published by Materials Today: Proceedings. He found at least 1,500 off-topic papers, many with abstracts containing “tortured phrases” that may have been written by translation or paraphrasing software, and a few with titles that had been previously advertised with author positions for sale online. 

He detailed his findings in a blog post today, and says that the journal – an Elsevier title – has published many articles that look like the work of a paper mill.

A researcher with 30 retractions and counting: The whistleblower speaks

Via U.S. SEC Office of the Whistleblower

Retraction Watch readers who have been following our coverage of retractions by Ali Nazari may have noticed that an anonymous whistleblower was the person who flagged the issues for journals and publishers. That whistleblower uses the pseudonym Artemisia Stricta, and we’re pleased to present a guest post written by him or her.

Something is seriously out of place with the roughly 200 publications by Ali Nazari, a scientist at Swinburne University who studies structural materials. Some of these problems have been known by journals and publishers for years — some since 2012 — yet their response has been mixed. Some have retracted papers. Some have decided not to, so far. And others have been mum.

Materials scientist will soon be up to 30 retractions

A researcher at Swinburne University of Technology in Australia will soon add three more retractions to his burgeoning count, making 30.

Ali Nazari has lost 27 papers from several journals, as we’ve reported over the past few months. According to an upcoming notice obtained by Retraction Watch, the International Journal of Material Research (IJMR) will be retracting three more:

UPDATED: Elsevier retracts a paper on solar cells that appears to plagiarize a Nature journal. But the reason is…odd.

The similarities between recent papers in two different journals about energy were striking — so striking that a number of people have taken to Twitter and Facebook to let the world know about them.

[1415 UTC, August 29, 2018: See update at the end of this post.]

One paper, “Systematic investigation of the impact of operation conditions on the degradation behaviour of perovskite solar cells,” was authored by a group of researchers in Lausanne, Switzerland and appeared on January 1, 2018 in Nature Energy. Its abstract reads: Continue reading UPDATED: Elsevier retracts a paper on solar cells that appears to plagiarize a Nature journal. But the reason is…odd.

Author under fire has eight papers retracted, including seven from one journal

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:

“Major advance” in solar power retracted for reproducibility issues

The authors of a highly cited 2016 research letter on a way to improve the efficiency of solar panels have retracted their work following “concerns about the reproducibility.”

Given the potential importance of the data, it would be nice to know what exactly went wrong, and why. However, the retraction notice doesn’t provide many details, and doesn’t even specify if the authors did indeed fail to reproduce the data.

The letter, titled “Graded bandgap perovskite solar cells,” was published in Nature Materials by a group out of the University of California at Berkeley and the affiliated Lawrence Berkeley National Laboratory. The 2016 article has been cited 16 times, according to Clarivate Analytics’ Web of Science, earning it the ranking of “highly cited.”

Berkeley heralded the findings in a press release as a “major advance” in the field of solar energy:

Author loses five recent papers for copying multiple figures, unspecified “overlap”

Two journals have retracted five recent papers by a researcher in Saudi Arabia after discovering extensive overlap, which one journal called plagiarism.

In one retracted paper, all schemes and figures are copies from other publications; in another, more than half of the figures are lifted. The journal that retracted the other three papers did not provide details about the nature of the overlap.

All five retracted papers—originally published within the last 15 months—have the same corresponding author: Soliman Mahmoud Soliman Abdalla, a professor of physics at King Abdulaziz University in Jeddah, Saudi Arabia.

According to a spokesperson for Polymers, readers flagged two papers in July 2017; both were retracted in August.

The spokesperson for Polymers told us that the journal ran the papers through the plagiarism detection software, iThenticate, but found “no significant levels of copied text.” The journal says it missed the overlap because:

Post-publication peer review in action: Science flags paper just days after publication

Science has issued an expression of concern for a widely covered materials science paper published on Friday, citing issues with the supplementary data.

The paper — which caught the attention of multiple news outlets — added properties to cotton fibers in vitro, potentially enabling researchers to manufacture fabric that can fluoresce or carry magnetic properties.

The move to issue an expression of concern was unusually quick. According to the journal, an expert who received the paper from a journalist under a media embargo contacted Science to flag issues in some of the supplementary data. At the time of this post, the paper does not yet have an entry on PubPeer.

Here’s the full expression of concern:

“Scientifically misleading errors” prompt authors to withdraw paper

A group of authors have withdrawn a paper after revealing a litany of issues to the journal that published it. Among those issues were “scientifically misleading errors,” “insufficient” validation, and a disagreement between the researchers on whether it should have been published at all.

“Optimal DNA structure of reverse-hairpin beacons for label-free and positive surface enhanced Raman scattering assays,” originally published in June in Optical Materials Express (OMEx), was retracted Aug. 7. The paper purported to describe a detection method for RNA associated with influenza virus. It has not yet been cited, according to Clarivate Analytics’ Web of Science.

Here’s the full list of issues cited in the retraction notice: Continue reading “Scientifically misleading errors” prompt authors to withdraw paper

Leibniz Prize belatedly awarded to scientist cleared of misconduct

Just before the March ceremony to bestow the coveted Leibniz Prize, the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) received some disturbing allegations. An anonymous tipster accused one of the 10 scientists slotted to receive the award, materials scientist Britta Nestler, of misconduct. So the DFG held the ceremony on March 15, but suspended Nestler’s award.

Four months later, Nestler now has her Leibniz, along with the €2.5 million in prize money. This week, the DFG — which awards the Leibniz — announced that it had given Nestler her prize on July 4, during its annual meeting, after determining the accusations were without merit.

Secretary General of the DFG and Chair of the Committee of Inquiry on Allegations of Scientific Misconduct Dorothee Dzwonnek said in a statement:
