Abstract

Expression of concern for ‘Design and development of highly sensitive PEDOT-PSS/AuNP hybrid nanocomposite-based sensor towards room temperature detection of greenhouse methane gas at ppb level’ by Syed Khasim et al., RSC Adv., 2021, 11, 15017–15029. DOI https://doi.org/10.1039/D1RA00994J.

RSC Advances is publishing this expression of concern in order to alert our readers that we are presently unsure of the reliability of the data reported in Fig. 3 of the article. Fig. 3b of this article is identical to Fig. 3a of ref. 1.

An investigation is underway, and an Expression of Concern will continue to be associated with the article until a final outcome is reached.
