Peer reviewer steals text for his own chemistry paper, gets sanctioned by journal

A peer reviewer apparently thought portions of a manuscript he was reviewing were so good he wanted them for himself.

Substantial sections of a paper that Junwei Di reviewed appear in his own paper on a method for making tiny particles of silver to precise specifications. Di is a chemist at Soochow University in China. The journal has banned Di from submitting papers or serving as a peer reviewer “for a certain time.”

The retraction note for the 2015 paper, “Controllable Electrochemical Synthesis of Silver Nanoparticles on Indium-Tin-Oxide-Coated Glass” explains how the editors at ChemElectroChem became aware of the plagiarism:

Author dispute, “considerable overlap” retract chemistry study

A chemistry journal has issued a retraction after “a thorough and time-consuming analysis” revealed two out of four authors did not agree to submitting an article published in May, which also contains “considerable overlap and redundancy” with another paper published a few weeks prior in a different journal.

Shortly after the paper appeared in Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, the journal was told “that parts of the manuscript were reused” from an article in the Journal of the Taiwan Institute of Chemical Engineers that was published online March 16. That led to the investigation, and the discovery of the additional authorship issues.

Here’s the full notice: Continue reading Author dispute, “considerable overlap” retract chemistry study

Journal retracts nanoparticles paper for duplicating figures

A paper on nanoparticles that target cancer cells has been retracted for duplicating figures from three other papers.

The articles all share a first author: Manasmita Das, based at the time of the research at the Indian Institute of Technology Kharagpur and the National Institute of Pharmaceutical Education and Research (NIPER). According to her LinkedIn profile, she is currently a postdoc at the University of North Carolina.

The abstract of the 2011 Bioconjugate Chemistry paper explains just what the new nanoparticles would be useful for:

Multifunctional nanoparticles, developed in the course of the study, could selectively target and induce apoptosis to folate-receptor (FR) overexpressing cancer cells with enhanced efficacy as compared to the free drug. In addition, the dual optical and magnetic properties of the synthesized nanoparticles aided in the real-time tracking of their intracellular pathways also as apoptotic events through dual fluorescence and MR-based imaging.

But according to the retraction note, figure duplications “seriously undermine the conclusions presented in the research article.” Here’s more about the source of those duplications from the full note: Continue reading Journal retracts nanoparticles paper for duplicating figures

JACS imaging paper “under editorial review”

The Journal of the American Chemical Society has issued an expression of concern over “the presentation of results” in a 2014 paper about a new probe for use in imaging.

We haven’t heard back from the journal nor the authors of the paper, so there’s not much we can officially say about what the journal is investigating.

Here’s the text from the expression of concern:

After 10 years, a whistleblower is vindicated. Here’s why he kept going.

Stefan Franzen doesn’t give up. Ten years ago, he began to suspect the data behind his colleagues’ research about using RNA to make palladium nanoparticles, a potentially valuable tool that ended up as a Science paper. Recently, the National Science Foundation (NSF) decided to cut off funding for Bruce Eaton and Dan Feldheim — currently at the University of Colorado at Boulder — and last week, Science retracted the paper. We talked to Franzen, based at North Carolina State University (NCSU), about his decade-long efforts, and how it feels to be finally vindicated.

Retraction Watch: How did you first begin to suspect the findings by Eaton and Feldheim?

Stefan Franzen: Starting in early 2005, I was collaborating with Drs. Eaton and Feldheim at NCSU, thanks to two joint grants from the W.M. Keck Foundation and NSF. During a group meeting in December of 2005, a graduate student showed electron microscopy data that were inconsistent with the assignment of the particles as palladium. Over time, we kept producing more data that called their findings into question; in April 2006, a postdoc showed that the hexagonal particles could be obtained without RNA. By then, I could see that there was a significant discrepancy between what was written in the articles and what was done and observed in the laboratory.

RW: How did you report your concerns?

Chemist sues University of Texas (again) to keep PhD

A chemist is suing the University of Texas a second time in an effort to keep the PhD she earned in 2008.

In 2014, school officials revoked Suvi Orr‘s degree after finding it was based, in part, on falsified data. Some of the data were also included in a paper in Organic Letters that was retracted in 2011 after some steps in the chemical synthesis the authors described were not reproducible. Orr, currently working at Pfizer, sued UT, and the school reinstated her degree.

Now, the school is trying to remove it again, according to the lawsuit, filed last week. The lawsuit says the school has scheduled a “hearing” on March 4, during which three undergraduate students and two faculty members will deliberate — “none of whom are qualified to evaluate the scientific evidence being used against S.O.,” the suit says.

Orr has requested a temporary injunction to halt the proceedings, and a hearing has been scheduled for next week, according to the Austin-American Statesman.

The suit argues the school does not have the right to strip Orr’s degree from her: Continue reading Chemist sues University of Texas (again) to keep PhD

After hesitating, Science retracts chemistry paper against authors’ wishes

Today, Science has retracted a 2004 paper that’s been under scrutiny for years, despite the authors’ objections.

This paper has a long backstory: Recently, a report from the National Science Foundation’s Office of Inspector General surfaced that announced the agency had cut off the authors from funding. Last month, editor Marcia McNutt told us that the journal planned to retract the paper as soon as possible. Then, on January 21st, “just as we were going to press with the retraction,” said McNutt, the authors submitted a correction, which Science wanted to take some time to consider.

Now, the paper has a retraction note, against the wishes of authors Bruce Eaton and Dan Feldheim, currently at the University of Colorado.

Here it is the retraction note:

Data irregularities force author to retract three solar cell papers

An engineer has retracted three papers on a method for making nanoscale materials that are useful in solar cells.

The papers, all published in ACS Applied Materials & Interfaces, contain irregularities in data, and one includes images “which have been published elsewhere and identified with different samples,” according to the note.

The first author on all three papers is Khalid Mahmood, who — according to the bio from a talk he gave last year on efficient solar cells — is currently a postdoc at King Abdullah University of Science and Technology in Saudi Arabia. He did the work in the retracted papers while a student at the Korea Advanced Institute of Science and Technology, where, according to the bio, he completed his PhD in two years.

Here’s the retraction note for the first paper (which also contains a typo in the title — “electrospay”)

Authorship dispute fells membrane paper

A membrane paper has been retracted only two months after publication in the Journal of Physical Chemistry B because of an authorship dispute.

The paper, “Magnetic Interaction of Transition Ion Salts with Spin Labeled Lipid Membranes: Interplay of Anion-Specific Adsorption, Electrostatics, and Membrane Fluidity,” has not been cited, according to Thomson Scientific’s Web of Knowledge. (It appears to be taken down entirely, but it looks like you can read its abstract here.)

Here’s the entire — very short — note:

Wound healing paper injured beyond repair

Errors in the interpretation of some of the data — the result of “procedural flaws” — are to blame for the retraction of a paper on a way to help skin grow back after injury.

The paper explores a method involving nanofibers. According to the abstract:

In this study, tilapia skin collagen sponge and electrospun nanofibers were developed for wound dressing…the collagen nanofibers stimulated the skin regeneration rapidly and effectively in vivo.

The paper was published January 19, 2015 by ACS Applied Materials and Interfaces, then retracted eight months later, in August. It has not been cited, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:
