The Editor-in-Chief would like to alert the readers that concerns have been raised regarding data similarity between this article [1] and the authors' later work [2]. The authors have stated that the two articles share similar synthesis techniques, which may have led to similar results.
Due to the extent of the similarities in the XRD and SEM data between the two articles, readers are advised to interpret these results with caution.
Rania Ramadan agrees to this Editorial Expression of Concern. M. K. Ahmed has not responded to any correspondence from the publisher about this Editorial Expression of Concern.
