Here’s the notice for “Chopstick Nanorods: Tuning the Angle between Pairs with High Yield,” originally published in June in Nano Letters by Rajasekhar Anumolu and Leonard F. Pease of the University of Utah:
This article is being retracted due to concerns over the integrity of the data. The originally published PDF of this article is available as Supporting Information.
The problems with the paper became public on Tuesday in a post by UCLA postdoc Mitch André Garcia on Chemistry Blog.
Among other problems, Garcia wrote that three of the paper’s images
show the boundary of one nanorod apparently overlapping the adjacent nanorod.
there was an investigation underway at the University of Utah into this matter and strongly encouraged me not to publish this story until the University completed its investigation.
A dean at Utah — which recently released the report of another unrelated misconduct investigation — confirmed for Garcia that there was an ongoing investigation, and said the university had been alerted to the potential issues by the journal.
