Authors dispute ethical lapse in case of double physics publication that wasn’t

Plasma Processes and Polymers has retracted a paper it published in March 2012 for what it describes as a “possible breach of ethics.”

That certainly sounds bad — if inconclusive — but the authors maintain the whole thing was a simple misunderstanding.

The article, “Plasma Acid: Water Treated by Dielectric Barrier Discharge,” came from the lab of Gary Friedman, a physicist at Drexel University in Philadelphia. The first, and corresponding, author was Natalie Shainsky, an award-winning graduate student at the school.

As the notice states: Continue reading Authors dispute ethical lapse in case of double physics publication that wasn’t

“Major errors” lead to retraction of Nature Photonics paper on quantum dots

Maybe it’s an occupational hazard of dealing with quantum physics — uncertainty and all that — but a group of Swiss researchers has retracted their paper on quantum dots after discovering “major errors” that undermined their conclusions.

The article, published in 2010 as a research letter in Nature Photonics, was titled “Polarization-entangled photons produced with high-symmetry site-controlled quantum dots,” by Eli Kapon and colleagues.

According to the retraction notice: Continue reading “Major errors” lead to retraction of Nature Photonics paper on quantum dots

Physics paper retracted because authors wrongfully claimed they got there first — in the same journal

Here’s a tip: If you’re going to claim you were first to discover something, even though you know you weren’t, don’t publish your claim in the same journal where the first finding appeared. Oh, and don’t ask the researchers who made the first discovery for help along the way.

Those, perhaps, are the cynical lessons from a retraction notice that appeared last week in the Journal of Chemical Physics: Continue reading Physics paper retracted because authors wrongfully claimed they got there first — in the same journal

Journal retracts nanoparticle paper, citing widespread misuse of sources

The  International Journal of Nanomedicine is retracting a paper it published in June that appears to contain an impressive amount of misappropriated text and figures.

The article, “Particokinetics: computational analysis of the superparamagnetic iron oxide nanoparticles deposition process,” came from a group at the Hospital Israelita Albert Einstein, in São Paulo, Brazil, led by Walter Cárdenas. According to the notice: Continue reading Journal retracts nanoparticle paper, citing widespread misuse of sources

Former Tokyo Tech materials researcher sanctioned after bringing forward evidence of data fabrication

A materials researcher faced three months without salary, retired from his research position and may have to return a portion of a grant worth $1 million US as punishment after a postdoc in his lab was caught fabricating data.

Seizo Miyata, formerly a materials researcher at the Tokyo Institute of Technology, headed a group that worked on carbon alloy catalysts. Last year, Miyata told Retraction Watch, he found evidence that postdoc Wu Libin had fabricated data.

Reached by Retraction Watch by phone, Miyata didn’t say who uncovered the evidence, nor how, but when he confronted Libin, the postdoc confessed. Miyata said he alerted Texas Tokyo Tech administrators last year, and requested the retraction of “Preparation of carbon-based catalysts for PEFC cathodes from aromatic polyamide with Fe compound,” which appeared in Applied Catalysis A: General in July 2011. That retraction notice reads: Continue reading Former Tokyo Tech materials researcher sanctioned after bringing forward evidence of data fabrication

Plagiarism costs Canadian lab-on-a-chip researcher a paper — in his own journal

We have long (well, for the past two years) wondered about the pitfalls of publishing in one’s own journal, and here’s a case that illustrates precisely how fraught that practice can be.

The journal Microfluidics and Nanofluidics has retracted a 2010 article, titled “Induced-charge electrokinetic phenomena,” by Dongqing Li and Yasaman Daghighi, of the University of Waterloo in Canada, for what appears to be extensive misappropriation of text and data.

As the notice explains: Continue reading Plagiarism costs Canadian lab-on-a-chip researcher a paper — in his own journal

Three more retractions for Vietnamese physicists who plagiarized a plagiarized paper

Last week, we brought you the story of Thong Duc Le and his colleagues, physicists who were forced to retract four papers, including one that cited, as we noted “their own study that had already been retracted for plagiarism.”

The team has now retracted three more papers: Continue reading Three more retractions for Vietnamese physicists who plagiarized a plagiarized paper

Mighty molten powder researchers publish paper in journal twice, months apart

A group of French researchers liked their paper on the properties of molten tin so much they published it twice. In the same journal. Four months apart.

The article, “Nitrogen spray atomization of molten tin metal: Powder morphology characteristics,” first appeared online in the January 2007 issue of the Journal of Materials Processing Technology. That one has been cited four times, according to Thomson Scientific’s Web of Knowledge.

In May 2007, the same group, sans two authors, published a paper online in the JMPT (and in January 2008 in print) with the identical title. That article — which managed to get cited three times — has now been retracted: Continue reading Mighty molten powder researchers publish paper in journal twice, months apart

Astrophysics retraction trail includes paper that plagiarized another already retracted for…plagiarism

Sometimes, the full story of scientific misdeeds isn’t clear until several retraction notices appear. Take the case of a group of Vietnamese astrophysicists led by Thong Duc Le.

If you were to read a Physics Letters B retraction notice about one of the group’s papers, “Search for cosmological time variation of the fine-structure constant using low-redshifts of quasar,” you wouldn’t have any idea why the paper was retracted, nor that the move was related to any other retractions: Continue reading Astrophysics retraction trail includes paper that plagiarized another already retracted for…plagiarism

Vacuum force researcher retracts paper that failed to name collaborators

Science doesn’t occur in a vacuum. Even vacuum science.

The International Journal of Modern Physics A has retracted a 2011 paper by a physicist who failed to acknowledge the contributions — instrumental, it seems — of his collaborators.

The paper, “Measurement of the Casimir Interaction Between a au Sphere and au Gratings” [au in this case being the atomic symbol for gold, not the French article], was published last summer by Ricardo Decca as part of a conference proceedings. According to the notice: Continue reading Vacuum force researcher retracts paper that failed to name collaborators
