What Caught Our Attention: After an expression of concern (EOC) is published in a journal, the usual procedure is to either publish a subsequent correction or retraction — or, unfortunately, leave it sit ad infinitum. But apparently, there’s another option.
Recently, RSC Advances added an interim update to a 2016 expression of concern (EOC), letting their readers know that the editors remain interested, and still concerned.
The first EOC said the journal had received “credible information” that the findings in Figures 1 and 3, and the supplementary data, may not be reliable; the journal said it would publish an update “when a final outcome is reached.” This second EOC acknowledges that there were problems with the supplementary data, but the experiments have been replicated. However, the corresponding author “cannot verify the origin of Fig. 1b and 3c.” The editors note that the EOC remains linked to the article until proof is provided that “the reported results are sound.”

The following article ‘Filled and peptide-modified single-walled carbon nanotubes: synthesis, characterization, and in vitro test for cancer cell targeting’ has been published in RSC Advances.
RSC Advances published an expression of concern in order to alert our readers to the fact that the Royal Society of Chemistry had been provided with credible information suggesting that the results presented in this paper, in particular Fig. 1 and 3 and the ESI, may not be reliable.
We are now able to provide the following update:
The characterisation data reported in Fig. S1 and S2 (ESI) were reproduced from a previous Chemical Communications paper which was co-authored by the corresponding author of this RSC Advances paper, Zhiyuan Hu.1 The corresponding author has confirmed that the characterisation data were not measured directly from the materials reported in this RSC Advances paper. The authors have repeated their synthesis and characterisation to provide the following replacement figures…
The corresponding author regrets that due to problems with file management he cannot verify the origin of Fig. 1b and 3c, therefore he cannot be certain that these images are representative of the materials reported.
The Expression of Concern will continue to be associated with this article until we receive independent verification from China University of Petroleum that the reported results are sound.
