Information on the retraction of an article published in Nature Materials

Information :

Synchrotron SOLEIL commissioned an independent inquiry, composed of scientific experts, in order to clarify the circumstances leading to the retraction, by the authors, of the article :  "Large local lattice expansion in graphene adlayers grown on copper", by Chaoyu Chen, José Avila, Hakim Arezki, Van Luan Nguyen, Jiahong Shen, Marcin Mucha-Kruczyński, Fei Yao, Mohamed Boutchich, Yue Chen, Young Hee Lee & Maria C. Asensio, published in the journal Nature Materials 17 450-455 (2018) on April, 9th, 2018.

The inquiry concluded that some of the results, presented by authors from SOLEIL in the article, grossly mislead the community, affecting the integrity of the published record and leading to erroneous conclusions. The inquiry also noted unethical scientific practices. SOLEIL direction has taken note of these shortcomings and has drawn all the necessary consequences. 

The Synchrotron SOLEIL, a Large Scale Research Infrastructure devoted to conduct leading-edge research and to make its facilities available to the scientific communities while providing them with the best support, will continue to exercise the utmost diligence in order to guarantee the scientific quality, integrity and honesty of all research undertaken in the laboratory.
