Second retraction for chemist from Portugal who forged names, data

chemengjrnChemical Engineering Journal has retracted a 2011 article from a group of researchers in Portugal after determining that the scientists made up their data.

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: Continue reading Second retraction for chemist from Portugal who forged names, data

Chemist loses two papers, one each for plagiarism and duplication

chem phys lettersA researcher at Shanxi Normal University in China has notched two retractions, once for plagiarism and one for duplication.

Saudi journal retracts paper on new chemicals for being, well, not new

JSaudChemIrony alert: If you’re going to publish a paper on purportedly new molecules, please try to make sure those substances are indeed novel. Here’s case were that wasn’t quite so.

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.) Continue reading Saudi journal retracts paper on new chemicals for being, well, not new

Publishing in triplicate leads to polymer paper retraction

Journal retracts two chemistry papers for plagiarism

commnonlinscinumsimCommunications 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?):

Author retracts materials paper for irreproducibility

tetrahedronA 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.

Here’s the notice: Continue reading Author retracts materials paper for irreproducibility

That’ll do it: Physics paper retracted for a “pattern that is unphysical”

j phys dLast December, we brought you the story of a math paper that was retracted because it made “no sense mathematically.” Today, we have that retraction’s cousin: A physics paper retracted because some of the data are “unphysical.”

Here’s the notice for “Room temperature ferromagnetism in pure and Co- and Fe-doped CeO2 dilute magnetic oxide: effect of oxygen vacancies and cation valence,” which was published in April 2011 in the Journal of Physics D: Applied Physics: Continue reading That’ll do it: Physics paper retracted for a “pattern that is unphysical”

When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

colloids and surfaces bThe journal Colloids and Surfaces B: Biointerfaces has retracted a 2011 paper by a group of researchers in India who misappropriated — and then manhandled — a pair of images from a previously published article by other scientists.

The paper, “Synthesis and characterization of chitosan and grape polyphenols stabilized palladium nanoparticles and their antibacterial activity,” was written by authors from various institutions in Tamil Nadu, and appeared online in December 2011 and in print the following April. It has been cited three times, according to Thomson Scientific’s Web of Knowledge.

Here’s the abstract: Continue reading When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

Chemistry papers retracted for “lack of objectivity:” The authors did their own peer review

synthreactSynthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry is retracting three articles for duplication — redundancy the authors, chemical engineers at Islamic Azad University, in Shahreza, Iran, appear to have gotten around by reviewing their own manuscripts. But, if they did say so themselves, those papers were really something!

Here’s the retraction notice for two of the papers, both of which appeared in 2012 and which were cited seven times and once, respectively, according to Thomson Scientific’s Web of Knowledge:
