A membrane paper has been retracted only two months after publication in the Journal of Physical Chemistry B because of an authorship dispute.
The paper, “Magnetic Interaction of Transition Ion Salts with Spin Labeled Lipid Membranes: Interplay of Anion-Specific Adsorption, Electrostatics, and Membrane Fluidity,” has not been cited, according to Thomson Scientific’s Web of Knowledge. (It appears to be taken down entirely, but it looks like you can read its abstract here.)
Here’s the entire — very short — note:
Errors in the interpretation of some of the data — the result of “procedural flaws” — are to blame for the retraction of a paper on a way to help skin grow back after injury.
The paper explores a method involving nanofibers. According to the abstract:
In this study, tilapia skin collagen sponge and electrospun nanofibers were developed for wound dressing…the collagen nanofibers stimulated the skin regeneration rapidly and effectively in vivo.
The paper was published January 19, 2015 by ACS Applied Materials and Interfaces, then retracted eight months later, in August. It has not been cited, according to Thomson Scientific’s Web of Knowledge.
Here’s the retraction note:
The authors of a letter describing the synthesis of ketonitrones have retracted it, after new data showed that they incorrectly reported the product structures and the reaction mechanism.
We’re not sure what exactly went wrong with the original data in the letter, “Transition-Metal-Catalyzed Ring Expansion of Diazocarbonylated Cyclic N-Hydroxylamines: A New Approach to Cyclic Ketonitrones,” published in Organic Letters.
Here’s the reaction that the paper reported, from the abstract:
A nearly ten-year-long series of investigations into a pair of plant physiologists who received millions in funding from the U.S. National Science Foundation has resulted in debarments of less than two years for each of the researchers.
The NSF Office of Inspector General recently posted its close-out report on its decision and a review of the University’s investigation, which had recommended a total of eight retractions or corrections. Although the investigator’s names have been redacted, the text of retractions and corrections quoted in the report corresponds to papers by Read the rest of this entry »
Environmental Science & Technology has issued a correction for a March 2015 paper on methane contamination from gas wells after learning that the authors failed to disclose funding from Chesapeake Energy Corp., a major U.S. energy producer.
The paper, “Methane Concentrations in Water Wells Unrelated to Proximity to Existing Oil and Gas Wells in Northeastern Pennsylvania,” came from a group led by Donald Siegel, of Syracuse University. In the correction, Siegel acknowledges having received “funding privately” from Chesapeake for the study, which found: Read the rest of this entry »
Three chemists at the Indian Institute of Technology Guwahati in India have retracted a paper from the Journal of Organic Chemistry because the “incorrect files were inadvertently used.”
The article, “Room-Temperature Cu(II)-Catalyzed Chemo- and Regioselective Ortho-Nitration of Arenes via C–H Functionalization,” described a protocol to perform nitration — the addition of nitro groups onto an organic compound — using an inexpensive copper catalyst.
All three authors signed the one-sentence notice:
A team of chemists at Hunan University and Zhejiang Shuyang Chemical Company in China have retracted a paper from the Journal of Chemical & Engineering Data after “inconsistencies with the literature” led them to discover “errors” in the way the data were reported.
Wang then went through the original notes with the first author, and realized that the data reported in the paper didn’t match the experimental results. The lab then conducted further experiments, and discovered that multiple corrections would be necessary. They were, as Wang told us: Read the rest of this entry »
The Journal of the American Chemical Society (JACS) has retracted three articles that had earned expressions of concern by chemistry researchers who were under investigation at the University of Texas, Austin.
The newly retracted articles have each been cited more than 50 times, according to Thomson Scientific’s Web of Knowledge.
The three papers are: Read the rest of this entry »
Drug researchers in India have lost their 2013 paper in ACS Medicinal Chemistry Letters because the first author fabricated findings.
The article, by a group from the Maharaja Sayajirao University of Baroda, Vadodara, in Gujarat, was attempting to synthesize and screen novel clot-busting drugs; one compound exhibited the same activity as aspirin or warfarin, but without increasing bleeding time.
Sadly, it appears as if this potential medical advance was not to be. Here’s the retraction notice for “Novel 2-Aminobenzamides as Potential Orally Active Antithrombotic Agents”: Read the rest of this entry »
According to last author Rory Waterman at the University of Vermont, an undetected reaction caused his lab to mistakenly mischaracterize the products of an iridium catalyst. The diligence of a graduate student brought it all to light, he noted: “In short, it was the ability of one of my group members to be a very good scientist.”
The letter, titled “High Activity and Selectivity for Silane Dehydrocoupling by an Iridium Catalyst,” was published in February. It has only accumulated 5 citations, according to Thomson Scientific’s Web of Knowledge.
