Last week, we reported on a retraction in the Journal of Analytical Atomic Spectrometry that left us a bit puzzled. The notice referred to a problem with “the way the data was presented,” but the authors told us this was just an error picked up in proofreading, somehow after the paper had been published online.
We now have much more of the story. The Royal Society of Chemistry’s May Copsey, who edits the journal, tells Retraction Watch: Read the rest of this entry »
The Journal of the American Chemical Society has retracted a 2009 paper on ethylene polymerization after the authors said they were unable to replicate their findings.
The article, “Bimetallic Effects for Enhanced Polar Comonomer Enchainment Selectivity in Catalytic Ethylene Polymerization,”came from the lab of Tobin Marks, a highly decorated — and grant-and-royalty-generating — chemist at Northwestern University.

The clincher: According to the journal, the researchers did not possess the proper lab equipment to perform the study as reported.
The article, “Detoxification of high-strength liquid pollutants in an ozone bubble column reactor: Gas–liquid flow patterns, interphase mass transfer and chemical depuration,” appeared in August 2011 and was written by Rodrigo J. G. Lopes and Rosa M. Quinta-Ferreira, from the Group on Environmental, Reaction and Separation Engineering in the Department of Chemical Engineering at the University of Coimbra. The paper has been cited twice, according to Thomson Scientific’s Web of Knowledge, both times by the original authors.
Here’s what the abstract has to say about the work: Read the rest of this entry »
The Journal of Saudi Chemical Society has retracted a 2011 paper by a researcher who lifted the entire article from a previously published paper by someone else.
The paper in question, “Synthesis and antimicrobial activity of some new quinazolin-4(3H)-one derivatives,” came from Adnan Kadi at Kind Saud University in Riyadh. But according to the retraction notice, only a few words in that title — “some” and “quinazolin” were accurate. “New,” certainly not. (We suppose “derivatives” hits the mark, but for the wrong reason.) Read the rest of this entry »
Communications in Nonlinear Science and Numerical Simulation has retracted a pair of articles by a group of chemists from Iran and the United States after finding evidence of plagiarism in the papers.
The researcher team included authors from Islamic Azad University, Ferdowski University of Mashhad and, perhaps somewhat incongruously, Ball State University in Muncie, Indiana.
The first paper, “An analytical approach to the stability of solitary solutions of cubic–quintic coupled non-linear Schrödinger equations,” appeared in 2009 and has been cited twice, according to Thomson Scientific’s Web of Knowledge. (Question: is an article that will ultimately be retracted for plagiarism considered to exist in a state of un-retracted retractionness, such that by detecting the plagiarized text the article immediately ceases to be?):
A materials scientist in Turkey has retracted a paper in the journal Tetrahedron after realizing that there was more to the compounds he was studying than he thought.
The article, “Novel donor–acceptor type thiophene pyridine conjugates: synthesis and ion recognition features,” appeared in April and was written by Fatih Algi, of the Laboratory of Organic Materials at Canakkale Onsekiz Mart University.
