Graphene has been hot for several years. Here’s what the Royal Swedish Academy of Sciences had to say about it in 2010 when awarding two researchers the Nobel Prize in Physics for their work:
Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.
But one researcher may have allowed his enthusiasm for graphene to get ahead of him. He and his unwitting co-authors have now lost two papers thanks to that enthusiasm.
Here’s the retraction notice for “Graphene magnet realized by hydrogenated graphene nanopore arrays,” published in 2011 in Applied Physics Letters, which went online on March 1:
Although the scientific content of the paper mentioned above is fully approved by all authors, we hereby retract this article, because it has been published in almost identical form in Phys. Rev. Lett. 107, 217203 (2011). Due to a fault of the corresponding author, the submission to Phys. Rev. Lett. took place without the knowledge of some of the co-authors. The corresponding author apologizes to the co-authors, the journal editors and publishers, and the scientific community for this serious breach of the accepted protocol for scientific publications.
And here’s the Physical Review Letters notice, from the week of March 16:
This Letter has been retracted by the corresponding author due to an instance of duplicate publication noted by a reader. The overlap with Ref.  is clearly excessive with identical figures and text. The corresponding author regrets allowing this duplicate publishing to occur without permission of the co-authors and apologizes to the readers and editors of Applied Physics Letters and Physical Review Letters.
We’ve contacted corresponding author Junji Haruyama, of Aoyama Gakuin University in Japan, and will update with anything we hear back.
