A team of physicists has lost their 2013 paper in the Journal of Optics after the publisher learned that the article had already appeared in print twice before.
The article, “Inscription of narrow bandwidth Bragg gratings in polymer optical fibers,” came from researchers at the Instituto de Telecomunicacoes, in Portugal, and the Aston Institute of Photonic Technologies, in Birmingham, England. Per the abstract: Read the rest of this entry »
The physics journal Pramana — a publication of the Indian Academy of Sciences — has retracted two studies by a group of researchers in Malaysia who appear to have cobbled together their papers from other sources.
The 2007 articles came from A.R.M. Yusoff, M.N. Syahrul and K. Henkel, of the University Science Malaysia, in Penang. One was titled “High resolution transmission electron microscope studies of a-Si:H solar cells,” and the other, “Hydrogenated nanocrystalline silicon germanium thin films.” The retraction notices are identical, and read: Read the rest of this entry »
More than two years ago, we wrote about a retraction for duplication in Biophysical Journal prompted by an email from pseudonymous whistleblower Clare Francis. That post generated a robust discussion, including one comment from someone calling himself or herself “Double Dutch.”
This past weekend, the last author of that paper, Rienk van Grondelle, left a lengthy response to that comment in which he explained how the duplication happened. We’ve confirmed that it was van Grondelle who left the comment, which we reproduce here in full (we’ve added paragraph breaks for readability): Read the rest of this entry »
The journal Applied Surface Science (okay, so maybe it’s not called ASS at the home office) is retracting a pair of articles in its December issue.
The first, “Structure and mechanical properties of Ni–P electrodeposited coatings,” appeared in 2009 and was written by a group of researchers in Beijing. It has been cited nine times, according to Thomson Scientific’s Web of Knowledge. Its problem: Plagiarism. According to the retraction notice: Read the rest of this entry »
The article, “Granular and intergranular conduction in La1.32Sr1.68Mn2O7 layered manganite system,” came mostly from a team of physicists at University Ibn Zohr, and appeared in June.
Last December, we brought you the story of a math paper that was retracted because it made “no sense mathematically.”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: Read the rest of this entry »
In February, we brought you the story of Konstantin Meyl, a
professor who claims to have developed “a self-consistent field theory which is used to derive at all known interactions of the potential vortex”
At the time, one of Meyl’s papers — which a reviewer had called “way out there” — had just been retracted, for duplication. Now a second paper — among the works from which the first retracted paper had drawn — has been retracted.
The article, “Temporally resolved imaging on quenching and re-ignition of nanosecond underwater discharge,” appeared last year in AIP Advances, a title of the American Institute of Physics. The authors were Yong Yang, Young I. Cho and Alexander Fridman. Yang is from Huazhong University of Science and Technology, in Wuhan, and Cho and Fridman are at Drexel University, in Philadelphia.
The Journal of Theoretical and Applied Physics has retracted a 2012 paper by a pair of Iranian cosmologists who failed to adequately cite one of the critical references on which they based their work.
We think that falls under the broader category of plagiarism — after all, as Heisenberg famously postulated, the same text cannot simultaneously appear in two published articles under different authorship. Or something like that.
Here’s the notice, for “Homotopy perturbation method to obtain exact special solutions with solitary patterns for Boussinesq-like B(m,n) equations with fully nonlinear dispersion:” Read the rest of this entry »
