The author of a 2016 paper has agreed to retract it after an investigation revealed that most of the article came from another research group at the same university.
According to the notice, the author based the majority of his paper on results generated by other scientists without their permission.
Here’s the retraction notice for “Controlled synthesis of magnetic block copolymers for anti-microbial purpose,” published in the Journal of Applied Polymer Science in November and retracted in February: Read the rest of this entry »
A group of researchers has lost two papers due to “high degrees of similarity with previously published works,” according to the notices.
The authors are objecting to the retractions, however, arguing the journal never gave them an opportunity to show their work is different from the previous papers.
Both papers were published in the International Journal of Plastics Technology, and share the same three authors, all based at Charan Singh University in India. They were retracted by the Editor in Chief, according to the notices.
“Effect of dynamic cross-linking on melt rheological properties of isotactic polypropylene (iPP)/ethylene–propylene diene rubber (EPDM)/nitrile rubber (NBR) elastomeric blends” was published in 2011. Here’s the retraction notice:
After a research group submitted two similar papers only days apart to different journals, one journal has retracted the paper — and told the other it should do the same.
The papers, by a group of authors based in Romania, describe a new polymer to stop the formation of biofilms. After a reader flagged the papers — which were submitted within eight days of each other in September, 2015 — as being similar, a journal has retracted one, and recommended the other journal retract the second. Although the second journal told us it planned to flag the paper with a notice alerting readers to the duplication, the notice has not yet appeared online.
The journal that issued the retraction — the International Journal of Polymer Analysis and Characterization (IJPAC) — called it a “a clear case of self-plagiarism,” according to the notice:
A paper describing the construction of a material that could be used in nuclear fuel containers has been retracted after the authors left out key details.
According to the editor, the omission made the authors’ method seem more novel than it was.
The material is described in “Structure and Mechanical Properties of Thick Copper Coating Made by Cold Spray.” It was published in the January 2016 issue of the Journal of Thermal Spray Technology.
According to the retraction notice, the authors did not specify in the paper how the first layer of copper was sprayed onto the steel:
The move prompted the journal to also retract an associated News & Views article.
A material science journal has retracted a paper after learning the authors took most of the content from a master’s thesis – and added the author as a co-author without his knowledge.
The authors must have really liked this thesis – they lost another paper in 2015 for copying from the same document.
Both retracted articles were co-authored by three researchers in the Department of Civil Engineering at Shahid Rajaee Teacher Training University in Tehran, Iran. The first author, Saeed Ghaffarpour Jahromi, serves as the University’s Dean of Faculty in the School of Civil Engineering.
Simon Hesp, a professor in the Department of Chemistry at Queens University in Kingston, Ontario, told Retraction Watch that he had notified both journals about the plagiarism when he recognized the thesis of Benjamin James Smith, who was a master’s student in his lab from 1998 to 2000. Hesp told us: Read the rest of this entry »
A physics journal has retracted a 2016 study after learning that the author published it without the knowledge or permission of the funder, which had a confidentiality agreement in place for the work.
According to the retraction notice in Applied Physics Letters, the paper also lifted content from other researchers without due credit. Given the “legal issue” associated with the breach of confidentiality, the journal has decided to remove the paper entirely.
According to the retraction notices — which all appear in Elsevier journals and contain the same text — the papers were accepted due to “positive advice of at least one faked reviewer report,” which were submitted from fictitious email accounts for reviewers suggested by the author.
All five studies were solely authored by Mariusz Książek, who is based at the Wrocław University of Science and Technology in Poland, and has denied any wrongdoing.
A spokesperson from the Wrocław University of Science and Technology confirmed that the university “has taken legal actions.”
Książek told Retraction Watch why he doesn’t agree with the decision to retract his papers: Read the rest of this entry »
According to the retraction notice in Advanced Materials, Mehdi Ghaffari — formerly based at Penn State — was solely responsible for the misconduct. Ghaffari’s LinkedIn page says he finished his PhD at Penn State in 2014, and now works as an independent consultant in New York, after a stint as a postdoc at Procter and Gamble.
A Penn State spokesperson sent us this statement: Read the rest of this entry »
According to the EOC, published in RSC Advances, the paper is now under investigation.
