An investigation reveals that data presented on Figure 5-7, 5-8, 5-9 and 5-10 of WEI Gaofei's (魏高飞) Master Thesis was reused from the article where he was listed as the first author. However, the same dataset was claimed to have been obtained under different experimental conditions in the two documents
Some duplicated parts (marked with same colour boxes) are observer in Figure 6A of the article [1].
LIN Qun (林群), an anesthesiologist at the First Affiliated Hospital of Fujian Medical University, has published three materials science articles focusing on the photocatalytic properties of nanomaterials, topics that are entirely unrelated to his professional background.
Duplicated parts (marked with same colour boxes) are observed on the black line in Figure 13c of this article [1], suggesting the spectrum was manipulated.
Recently, the 5GH Team received an anonymous e-mail accusing the ethical statement in article [1] of being false. A further investigation by the 5GH Team identified two additional articles [2–3] that also reported the same so-called ethical approval number, SQ2018-039-01.
The ethics statements on two article [1, 2] are found to be questionable. Due to authors' violation against the ethics management regulations in China, it remains unclear whether such conclusion in article [2] is solid. The 5GH Team is seeking a volunteer team to replicate the study. If any group is interested, they are welcome to contact the Team at 5GH@5gh.org.cn.
