Expression of Concern: Synthesis, structural, optical, morphological and magnetic characterization of copper substituted nickel ferrite (CuxNi1−xFe2O4) through co-precipitation method

The Original Article was published on 31 August 2017

The Editor-in-Chief is issuing an editorial expression of concern regarding the article [1]. While the article presents novel information regarding chemical co-precipitation-based synthesis and characterization, the Editor-in-Chief is concerned regarding the amount of overlap with the articles [2, 3]. None of the authors have responded to any correspondence from the editor or publisher about this overlap or the Editorial Expression of Concern.
