RETRACTED: Numerical Case Study of Chemical Reaction Impact on MHD Micropolar Fluid Flow Past over a Vertical Riga Plate (Materials, (2022), 15, 12, (4060), 10.3390/ma15124060)

The Materials Editorial Office retracts the article “Numerical Case Study of Chemical Reaction Impact on MHD Micropolar Fluid Flow Past over a Vertical Riga Plate” [1], cited above. Following publication, concerns were brought to the attention of the publisher regarding the validity of the parameters and equations presented in this article [1]. Adhering to our complaint procedure, an investigation was conducted by the Editorial Office and Editorial Board. While the authors fully cooperated with the Editorial Office during the investigation, they were unable to satisfactorily explain the presence of a number of significant anomalies within the parameters and the overall validity of the presented equations. Given the overall impact of these anomalies and validity concerns, the Editorial Board and Editor-in-Chief were unable to confirm the reliability of the findings and subsequently decided to retract this paper as per MDPI’s retraction policy (https://www.mdpi.com/ethics#_bookmark30, accessed on 29 May 2024) and in line with the Committee on Publication Ethics retraction guidelines (https://publicationethics.org/retraction-guidelines, accessed on 29 May 2024). This retraction was approved by the Editor-in-Chief of the journal Materials. The authors disagree with this retraction.
