Retraction note to: J Mater Sci: Mater Electron (2014) 25:303–310 https://doi.org/10.1007/s10854-013-1586-3


The Editor-in-Chief has retracted this article due to irregularities in figures in this article. Specifically:

  • In Fig. 5A, particles created using different methods show an N2 adsorption–desorption isotherms with the same shape after vertical scaling and shift.

  • In Fig. 5B, in the co-precipitation method at 600°C and 800°C, the pore size distributions appear to be identical.

The Editor-in-Chief has therefore lost confidence in the veracity of the results presented in this article.

A. E. Shalan does not agree to this retraction. I. Osama, M. M. Rashad and I. A. Ibrahim have not responded to any correspondence from the editor/publisher about this retraction.
