A chemistry journal has retracted a 2020 review article by a nanotube researcher who fabricated and falsified data in dozens of studies. The latest retraction for Naohiro Kameta brings his total to 40, earning him a place on the Retraction Watch Leaderboard.

In a 2020 review article in Chemical Reviews, 24 of the 610 works Kameta and his coauthors cited had themselves been retracted following the publication of the paper, according to the retraction notice. Because these references were "important components" of the review article, "the narrative and claims presented can no longer be upheld," the notice reads. All 24 of the works mentioned in the retraction notice were among 42 papers identified as fraudulent in a 2024 investigation by Japan’s National Institute of Advanced Industrial Science and Technology (AIST).

As AIST wrote in its report about the investigation, Kameta repeatedly altered electron micrographs and misrepresented scale bars in the 42 papers they found linked to misconduct so he could publish as many papers as possible. The misconduct was evident across nearly two decades of Kameta’s work, according to AIST.
