The retraction note for “Preparation and dielectric properties of BaTiO3:epoxy nanocomposites for embedded capacitor application” is short and sweet. Here it is, in full:
A group of authors is retracting a paper from Structure following a Brandeis University investigation that found the first author had fabricated a key result.
Former graduate student Kelsey Anthony was first author of the paper, “High-Affinity Gold Nanoparticle Pin to Label and Localize Histidine-Tagged Protein in Macromolecular Assemblies, which was published online in February 2014. At the time, the Science at Brandeis blog noted: Read the rest of this entry »
The images in question show sheets after a few rounds of a process called “constrained groove pressing,” which smushes sheets between two grooved plates, and then between two flat plates, to evaluate how the material holds up.
According to the retraction note for the paper, imaging performed by a third party “may not be trustworthy.”
The paper has been cited 42 times, according to Thomson Scientific’s Web of Knowledge.
The paper, “Ionic liquid assisted synthesis of flexible and super-hydrophobic porous gels,” described the synthesis of a form of flexible aerogels “through a facile one-pot preparation,” according to the abstract. According to Thomson Scientific’s Web of Knowledge it has been cited zero times.
According to the notice, the senior author told the journal that the data came from the lab Li used to work in at the University of Rome Tor Vergata, but the P.I. in Italy didn’t know about the paper.
The article, “The post-peak spectra in electron energy loss near edge structure,” came from a group led by one Feng Tian, a materials scientist at Shanghai University for Science and Technology. The other authors were Peter Shattschneider and Micheal Stoger-Pollach, of the Vienna University of Technology. Except that they weren’t.
Asking for a retraction was “an overbearing response, though I agree that the student screwed up big time”
Just two months after a PhD student at King Fahd University of Petroleum and Minerals in Saudi Arabia published a paper in August without the knowledge of his co-author, a professor at the university, the paper was retracted by Cellulose.
Here’s the notice for “Corrosion protection of steel sheets by chitosan from shrimp shells at acid pH,” by graduate student Ubong M. Eduok and professor Mazen M. Khaled (well, not really by Khaled): Read the rest of this entry »
Here’s a prime example of the consequences of that bureaucratic foot-dragging: Ten months after being told that Fazlurrahman Khan had fabricated his data, and two months after announcing two of Khan’s papers would be retracted from two of its journals, Elsevier still has not retracted either paper.
Worse, at least one of the papers, “Degradation of 2,4-dinitroanisole (DNAN) by metabolic cooperative activity of Pseudomonas sp. strain FK357 and Rhodococcus imtechensis strain RKJ300,” in the journal Chemosphere, has been cited since the announcement was made. In fact, the paper was published in Journal of Hazardous Materials, the Elsevier journal that is dragging its feet retracting another of Khan’s papers, “Aerobic degradation of 4-nitroaniline (4-NA) via novel degradation intermediates by Rhodococcus sp. strain FK48.”
According to the retraction notice, the authors’ institutions investigated and found that not only was the data not reproducible, but “not all co-authors on the manuscript were aware of or agreed to the content and scientific conclusions in the article.”
