Chem paper retracted because “a significant amount of data” was wrong

Jced_coverThe editors of ACS’s Journal of Chemical and Engineering Data have sunk a paper on halogenated alkanes after realizing that “a significant amount” of the data was “inaccurate,” thereby “invalidating” the paper.

Here’s the notice for “Influence of Solvent Nature on the Solubility of Halogenated Alkanes” (which has only been cited twice, according to Google Scholar): Continue reading Chem paper retracted because “a significant amount of data” was wrong

Chemists Bielawski and Wiggins up to eight expressions of concern, one retraction

Two researchers who already had three expressions of concern under their belts have five more, plus a retraction.

Kelly Wiggins and Christopher Bielawski share authorship on all the papers in question. After the first set of EoCs, Bielawski, at the time a PI at UT Austin, told Chemistry and Engineering News that a “former lab member” had admitted to faking the data. The recent retraction indicates that University of Texas at Austin’s Office of Research Integrity formally investigated the lab, and determined that Bielawski was telling the truth about a former lab member being to blame.

Bielawski has since taken a post at Ulsan National Institute of Science and Technology in South Korea. He told us that move was unrelated to anything that happened at UT Austin, but declined to answer other questions. Wiggins got a postdoc at the University of Illinois, which an Illinois spokesperson confirmed lasted from July 1 2013 to January 22 2014; we’re waiting to hear back on our question about whether her departure had anything to do with misconduct.

Here’s the retraction notice for “A Mechanochemical Approach to Deracemization,” in Wiley journal Angewandte Chemie: Continue reading Chemists Bielawski and Wiggins up to eight expressions of concern, one retraction

Nanoparticle paper earns retraction for lack of reproducibility

issue 1 - RSC Advances_2012.inddA nanoparticle article published earlier this year has been retracted by RSC Advances for lack of reproducibility, although we haven’t been able to get more details about what happened.

Here’s the notice for “Sonochemical synthesis of poly(methyl methacrylate) core–surfactin shell nanoparticles for recyclable removal of heavy metal ions and its cytotoxicity” (freely available but requires sign-in): Continue reading Nanoparticle paper earns retraction for lack of reproducibility

It’s happened again: Journal “cannot rule out” possibility author did his own peer review

ijkcThomson Reuters’ online peer review system ScholarOne is having quite a year.

This summer, a scientist exploited basic security flaws in how the system accepts author suggestions for peer reviewers to review a whole pile of his own manuscripts, ultimately resulting in the retraction of 60 papers and the resignation of the Taiwan minister of education.

Now, another journal that uses the system, Wiley’s International Journal of Chemical Kinetics, has retracted a paper because the authors provided their own peer reviewers and “the identity of the peer reviewers could subsequently not be verified.”

We asked editor Craig A. Taatjes if he was concerned the authors had conducted their own peer review. His response is reflective of many of the breaches we’ve seen so far for these online systems: Continue reading It’s happened again: Journal “cannot rule out” possibility author did his own peer review

A tale of two notices as Tunisian chemists lose two papers for duplicated data

molecules-logoMolecules has pulled a 2010 article by a trio of chemists from Tunisia who tried — and succeeded, for a while, at least — to publish the same data twice. The article was titled “An Expeditious Synthesis of [1,2]Isoxazolidin-5-ones and [1,2]Oxazin-6-ones from Functional Allyl Bromide Derivatives.” And indeed it was expeditious. Here’s the notice: Continue reading A tale of two notices as Tunisian chemists lose two papers for duplicated data

Authors retract two spectroscopy papers when follow-up results don’t match

analytical methodsThe authors of two spectroscopy papers in Royal Society of Chemistry journals have retracted them.

Here’s the notice for “Determination of silk fibroin secondary structure by terahertz time domain spectroscopy” (free, but requires sign-in) in Analytical Methods, which is almost identical to this notice in Analyst: Continue reading Authors retract two spectroscopy papers when follow-up results don’t match

Is it better to retract a paper, or publish a letter calling the conclusions “unphysical?”

langd5_v030i025.inddSometimes publishers and authors decide it’s easier to retract a paper than leave it up for discussion by other scientists.

That seems to be the case here: The authors of a paper in Langmuir retracted it in September for a math mistake, but not before the journal refused to publish a comment criticizing the publication.

Here’s the notice for “Drainage of a thin liquid film between hydrophobic spheres: Boundary curvature effects:” Continue reading Is it better to retract a paper, or publish a letter calling the conclusions “unphysical?”

Structure fumble sinks second of author’s JACS papers

jacsat_v136i001.inddProof that organic chemistry is hard for everyone, not just pre-meds: A paper in the Journal of the American Chemical Society was retracted after the structures of compounds being studied were “misassigned.”

Another study by author Doo Ok Jang, also in JACS, was retracted in 2013 for the same reason; you can read our coverage here. Jang and Sang Yoon Kim published that one in 2008; the paper we’re talking about today was published in 2010 by Jang and Sung Jun Kim.

Chemistry paper in Science earns expression of concern for unreliable data

science 62714A 2011 paper in Science has been subjected to an expression of concern and has led to an investigation by the Texas university where the work was done.
