RETRACTION: I.C. Ezema and V.S. Aigbodion, “Explicit Microstructural Evolution and Electrochemical Performance of Value Added Palm Kernel Shell Ash Nanoparticle/A356 Alloy Composite [Explizite Mikrostrukturelle Entwicklung Und Elektrochemisches Verhalten Eines Verbundwerkstoffes Aus Palmkernschalenasche-Nanopartikeln in Der Aluminiumlegierung AlSi7Mg],” Materials Science and Engineering Technology 51, no. 3 (2020): 324-329, https://doi.org/10.1002/mawe.201900071.

The above article, published online on 17 March 2020 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Jörg Ellermeier; and Wiley-VCH GmbH. The retraction has been agreed upon following an investigation into concerns raised by a third party. The investigation revealed that elements from Figures 2, 3, and 4 were found to be duplicated in articles published elsewhere by one of the same authors. The figures containing the duplicates are described as representing different materials. The authors acknowledged the presence of the duplications and indicated that they occurred inadvertently. However, they were unable to produce any original data. Due to the extent and nature of the duplications, the editors consider the results and conclusions reported in this article unreliable. The authors were informed of the retraction.
