Retraction note: Tunable decorated flake interlayers of functionalized graphene oxide for energy storage devices (Applied Physics A, (2022), 128, 7, (557), 10.1007/s00339-022-05707-6)

The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding some of the data presented in the figures. Specifically, the abundance tables in Fig. 3 don’t appear to correspond to the peaks in the EDX spectra; in addition, the Tauc plot band gap estimation in Fig. 4 appears inaccurate. The authors provided data files to address these concerns. Further checks by the published found that the data presented in Figs. 1, 3 and 4 did not accurately match the original data files. Additionally, Fig. 2c and d appear highly similar (with a different colour scheme). The Editor-in-Chief therefore no longer has confidence in the presented data. The authors have not responded to any correspondence from the publisher about this retraction.
