When researchers submitted a paper about a type of microparticle to PNAS, they wanted to give credit where it was due, and cite an unpublished manuscript that helped guide their work. But the journal’s policy forbid citing unpublished work, and the reference was removed before publication. Now, concerns from the authors of that unpublished work have prompted the journal to have a change of heart.
An engineer in South Korea has lost 30 papers, at least seven of which for duplication and plagiarism. He has also been fired from his university position.
Soon-Gi Shin, whose affiliation was listed as Kangwon National University in Gangwon, is the sole author on the majority of the papers, published in four journals between 2000 and 2015.
Taewan Kim, the dean of international affairs at the university, told Retraction Watch that Shin was fired on August 21, 2017, over “violation[s] of research ethics.”
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.”
Several years ago, Chris Dames thought he had made an exciting discovery, a “secret sauce” that would allow him to design a device using a novel mechanism.
In a 2014 Nature Communications paper, Dames—who works at the University of California at Berkeley—and his team described the first experimental results for the device, a photon thermal diode. A thermal diode conducts heat in one direction but not in the other, and in theory, could have broad applications—for example, provide barriers that shield buildings from excess heat or use heat to power computers.
But two years later, in August 2016, a colleague thought he had discovered a fundamental error in the design of the experiments. Bair Budaev, who also works at the University of California at Berkeley, believed that the authors made a “a fundamental symmetry error” which invalidated their results.

An engineering researcher has written about models tackling a range of complex issues — security problems in Iraq, poverty in Europe, and emergency responses to humanitarian crises. But there may be some limits to his expertise: Between 2016 and 2017, five journals have retracted five of his papers, citing plagiarism.
Some of the notices describe the plagiarism as “extensive,” “significant,” and “substantial.” One journal editor, who retracted one of Kubilay Kaptan’s papers last year, told us the paper “was simply a direct copy from an existing one.”
The editor noted that Kaptan — who lists his affiliation as the Civil Engineering Department at Beykent University in Istanbul — claimed to be “the victim of a personal smear campaign, which involved submitting plagiarised manuscripts in his name.” We reached out to Kaptan several times by phone and email to verify this claim, but did not hear back.
Here’s the most recent retraction, for a 2016 paper published in Journal of Refugee Studies: Continue reading Plagiarism costs author five papers in five different journals
The first author of a 2013 chemistry paper is objecting to his co-authors’ decision to retract the paper, which contains duplicated figures.
We recently encountered a similar scenario with papers by first author Khalid Mahmood. In late 2015, Mahmood lost three papers in the journal ACS Applied Materials & Interfaces over duplicated images. One of the notices also indicated that the figures had “been published elsewhere and identified with different samples” — the same language used in the notice of the most recent retraction, in Journal of Materials Chemistry C.
Mahmood performed the work on the papers at Korea Advanced Institute of Science and Technology (KAIST), along with his two co-authors, Seung Bin Park and Hyung Jin Sung (also co-authors on two of the retracted papers in ACS Applied Materials & Interfaces).
Seung Bin Park, who is dean of the College of Engineering at KAIST, told us: Continue reading First author objects to retraction (his fourth) in chemistry journal
A physics journal has retracted a 2011 paper by a group of scientists based in Italy, noting it’s “literally copied” from a paper by the same authors.
This is the 12th retraction for the paper’s first author Alberto Carpinteri, who is known in the engineering community for championing some controversial ideas, such as that the Shroud of Turin is as old as Jesus (contradicting carbon dating). In 2015, a journal he used to edit — Meccanica — retracted 11 of his papers, noting that “the editorial process had been compromised.”
In the latest notice, the Journal of Statistical Mechanics: Theory and Experiment (JSTAT) says its investigation found a substantial portion of the paper—including the main analysis and conclusion—had been lifted from a paper published in another journal several months before.
Last author of the latest paper to be retracted, Amedeo Manuello Bertetto from Polytechnic University of Turin, told us the authors strongly opposed the journal’s decision: Continue reading Controversial researcher loses 12th paper that’s “literally copied;” authors object
A researcher has threatened to sue publisher Taylor & Francis for mentioning a misconduct investigation into his work in a retraction notice.
According to the notice, the publisher retracted a 2008 paper and a book chapter after learning about a misconduct investigation into the work of Mark Jackson, a department head and endowed chair, respectively, at universities in Kansas.
Unfortunately, we don’t know much about the nature of the misconduct investigation; Jackson told us he initiated the retractions after raising concerns his colleagues had violated intellectual property. He has since told the publisher he would take legal action if it didn’t remove the phrase noting that the retractions stem from a misconduct investigation into his work from the notice.
Here’s the notice, issued by Materials Science and Technology:
Jae Hyo Park, who is pursuing his PhD, and Seung Ki Joo, a professor in the department of material science and engineering at Seoul National University in South Korea, appear on all five papers as first and last author, respectively.
According to an official at IOP Publishing, the retractions began when a third party contacted them last March about “potential misconduct” in a paper published earlier that year in one of its journals—Journal of Physics D: Applied Physics. The IOP official Simon Davies explained: Continue reading Five retractions for engineering duo in South Korea over duplication, fraudulent data
A researcher in South Korea has retracted a 2016 paper on which he is listed as senior author because a former student wrote and published the article without his permission.
According to the retraction notice, the former student also fabricated data and plagiarized “a substantial amount of material” from previous papers published by the senior and middle author.
Here’s the retraction notice for “Oleaginous yeast-based production of microbial oil from volatile fatty acids obtained by anaerobic digestion of red algae (Gelidium amansii),” published in the Korean Journal of Chemical Engineering in April 2016 and retracted in January: Continue reading Faked data, plagiarism, no co-author okays…yeah, this paper’s been retracted
