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: Read the rest of this entry »
Research misconduct finding — which university won’t discuss — leads to second retraction for prominent physicist
A rising star in nanotechnology, Dmitri Lapotko, has received his second retraction within a month over “a finding of research misconduct” that the university will apparently only disclose on a need-to-know basis.
According to the notice, the journal’s editor and publisher issued the retraction after Lapotko’s former institution—Rice University in Houston—notified them of research misconduct and cited figure duplication issues, which meant the results “should not be relied upon and may be scientifically unsound.”
We recently covered the Belarusian physicist’s first retraction in the journal Theranostics, in which an official at Rice would not confirm a misconduct inquiry, telling us that, “Rice University’s investigations of research misconduct are confidential.”
This time, however, the retraction notice explicitly states that a Rice University research integrity officer reported research misconduct to the journal Applied Physics Letters (APL). We contacted the official, B.J. Almond, who still stuck to the original script: Read the rest of this entry »
What’s more, the authors omitted key findings that would enable others to reproduce their experiments.
According to the notice, the authors used a value to calculate a feature of electrons—called mobility—that “was approximately 100 times too small,” which led to results that were “100 times too large.” The notice also details several gaps in the presentation of experimental results, which preclude others from duplicating the experiments.
Here’s the retraction notice for “Bulk- and layer-heterojunction phototransistors based on poly[2-methoxy-5-(2′-ethylhexyloxy-p-phenylenevinylene)] and PbS quantum dot hybrids:” 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.
Graphene has been hot for several years. Here’s what the Royal Swedish Academy of Sciences had to say about it in 2010 when awarding two researchers the Nobel Prize in Physics for their work:
Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.
But one researcher may have allowed his enthusiasm for graphene to get ahead of him. He and his unwitting co-authors have now lost two papers thanks to that enthusiasm. Read the rest of this entry »
Obfuscation watch: Self-plagiarism (we think) leads to retraction of nanorod paper in Applied Physics Letters
C. P. Snow famously bemoaned the gulf between science and the humanities. The following retraction might be the sort of thing that would have given the physicist-cum-author fits for its estrangement from the English language.
Writing in the latest issue of Applied Physics Letters, a team from
China Singapore and MIT appear to be confessing a case of self-plagiarism in their 2005 paper, “Growth of single crystal ZnO nanorods on GaN using an aqueous solution method: (we added a link to the earlier paper)” Read the rest of this entry »
