The articles, published online earlier this year, recently received an expression of concern after the journal realized the guest editor David Gao, at the Federation University Australia, had coordinated the peer-review process. This was a major no-no, since Gao was also an author of 11 of the 13 papers. Mathematics and Mechanics of Solids slated the articles to be peer reviewed again, by reviewers not chosen by Gao.
Gao told us what happened next, from his perspective — he changed his mind about publishing the papers in MMS:
Thirteen papers in Mathematics and Mechanics of Solids now have an expression of concern, after it came to light that an author on most of the papers coordinated the peer-review process.
David Y. Gao, a well-known and prolific mathematician at the Federation University Australia, is the author of 11 of the papers, and also the guest editor of the special issue in which they were set to appear. The papers were published online earlier this year.
A spokesperson for SAGE, which publishes the journal, confirmed that the publisher decided to re-review the papers after learning about Gao’s role in the peer-review process:
Authors have retracted a highly cited Nature letter that purported to discover a much sought-after, stable light source from quantum dots, after they realized the light was actually coming from another source: the glass the dots were affixed to.
When the paper “Non-blinking semiconductor nanocrystals” was published in 2009, it received some media coverage, such as in Chemistry World. That’s partly because very small sources of “non-blinking” light could have wide-ranging, big-picture applications, author Todd Krauss, a physical chemist at the University of Rochester, told us:
Off the top of my head, a quantum computer. Quantum cryptography is another one. People want a stable light source that obeys quantum physics, instead of classic physics.
The retraction note, published Wednesday, explains how the researchers found out the effect was coming from the glass, not quantum dots:
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 »
