Alleged Data Manipulation in Nano Letters and ACS Nano from the Pease group
A recent paper from Rajasekhar Anumolu and Leonard F. Pease in Nano Letters entitled, “Chopstick Nanorods: Tuning the Angle between Pairs with High Yield“, had a collection of very interesting TEM images. Below are a set of images from both Figure 4E and 4F.
The images below show the boundary of one nanorod apparently overlapping the adjacent nanorod. This is not the only type of artifacts that are visible.

Prior to publishing this story Jeffrey R. Botkin, Associate Vice President for Research at University of Utah, contacted me confirming that “the University of Utah was informed of this matter by the editor of the journal and the University is conducting a thorough investigation for research misconduct.”
Update (8/15): Nano Lett paper is withdrawn.
