Retraction Note: Bull. Mater. Sci. (2018) 41:29 https://doi.org/10.1007/s12034-017-1520-z

The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding the authenticity of the presented data. Specifically:

  • The samples in Fig. 1a and b appear to contain repeated patterns, which are unlikely to occur naturally in electron microscopy images.

  • The graph in Fig. 5a appears to contain unusual features that would result in two y values for the same x value around x=10 and x=17.

  • The top sample in Fig. 6a and left image in Fig. 9a present unusually similar edges.

The Editor-in-Chief therefore no longer has confidence in the presented data.

Samira Agbolaghi has not responded to any correspondence from the editor or publisher about this retraction. The editor has not been able to obtain current email addresses for Maryam Nazari, Homa Gheybi, Saleheh Abbaspoor and Farhang Abbasi.
