University of Utah investigation fingers chem engineering grad student for misconduct

acs nanoA second retraction has been issued in a case of research misconduct at the chemistry department of chemical engineering at the University of Utah.

The first retraction, in August of 2013, got a lot of attention for how poorly faked the figures were. At the time, an expression of concern was issued on the paper that has just been retracted.

Today, we exchanged emails with Jeffery Botkin, the research integrity officer at the University of Utah, who ran the investigation into the misconduct. He summarized the report for us below. Continue reading University of Utah investigation fingers chem engineering grad student for misconduct

Is it better to retract a paper, or publish a letter calling the conclusions “unphysical?”

langd5_v030i025.inddSometimes publishers and authors decide it’s easier to retract a paper than leave it up for discussion by other scientists.

That seems to be the case here: The authors of a paper in Langmuir retracted it in September for a math mistake, but not before the journal refused to publish a comment criticizing the publication.

Here’s the notice for “Drainage of a thin liquid film between hydrophobic spheres: Boundary curvature effects:” Continue reading Is it better to retract a paper, or publish a letter calling the conclusions “unphysical?”

Solvent paper dissolves under heat of institutional investigation

Jced_coverA chemical engineering paper published in February has been retracted for data and authorship problems.

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.”

Here’s the notice in the Journal of Chemical & Engineering Data for “Ionic Liquids as Promising Solvents for Biomass Derived Mannitol and Xylitol”: Continue reading Solvent paper dissolves under heat of institutional investigation

Researcher who broke into lab up to nine retractions

Structure fumble sinks second of author’s JACS papers

jacsat_v136i001.inddProof that organic chemistry is hard for everyone, not just pre-meds: A paper in the Journal of the American Chemical Society was retracted after the structures of compounds being studied were “misassigned.”

Another study by author Doo Ok Jang, also in JACS, was retracted in 2013 for the same reason; you can read our coverage here. Jang and Sang Yoon Kim published that one in 2008; the paper we’re talking about today was published in 2010 by Jang and Sung Jun Kim.

Researcher who tampered with investigation up to 8 retractions

Journal of Medicinal ChemistryKarel Bezouška, the scientist who tried to derail an investigation into his work by breaking into a lab refrigerator has had an eighth paper retracted.

Chemists lose JACS silicone paper over data dispute

Journal of the American Chemical SocietyA pair of chemists at Ball State University in Indiana has lost their paper in the Journal of the American Chemical Society on silicone in a dispute over the provenance of the data.

The article, “Silicone Electrosynthesis from Silica Raw Materials at Room Temperature,” was written by Jeffrey E. Dick, a grad student, and Daesung Chong. It appeared in JACS in March.

As the abstract explained: Continue reading Chemists lose JACS silicone paper over data dispute

Scientist found to have falsified data in thesis sues to keep her PhD

org lettersIn August 2012, the authors of “Novel Approach to the Lundurine Alkaloids: Synthesis of the Tetracyclic Core,” a paper in Organic Letters, retracted it:

The authors retract this Organic Letters communication on the basis that the RCM of 24 to give 25 (Scheme 6) is not reproducible; thus, the reduction of 25 to give 26 (Scheme 7) is also not reproducible.

The case was covered in some detail by The Heterocyclist blog, and also by Derek Lowe at In The Pipeline, who called it “an odd retraction.” Lowe recently picked up the story with an update: The first author, Suvi Orr, is suing the University of Texas-Austin, where she earned her PhD and did the work, to stop them from taking away her degree.

The Austin American-Statesman reported last month: Continue reading Scientist found to have falsified data in thesis sues to keep her PhD

SK Sahoo notches sixth retraction

am&IChemist Sanjeeb Kumar Sahoo, of the Institute of Life Sciences in Bhubaneswar, India, has earned his sixth retraction for image shennanigans, this time in Applied Materials & Interfaces.

Sahoo, as we reported last year, had lost five articles in Acta Biomaterialia  for what the journal called “highly unethical practices.”

The latest retraction involves an article titled “Composite Polymeric Magnetic Nanoparticles for Codelivery of Hydrophobic and Hydrophilic Anticancer Drugs and MRI Imaging for Cancer Therapy,” which first appeared online in 2011 in AM&I, a publication of the American Chemical Society.

The paper has been cited 40 times, according to Thomson Scientific’s Web of Knowledge. According to the abstract: Continue reading SK Sahoo notches sixth retraction
