RETRACTED: Gyrotactic Motile Microorganisms Impact on Pseudoplastic Nanofluid Flow over a Moving Riga Surface with Exponential Heat Flux (Crystals, (2022), 12, 9, (1308), 10.3390/cryst12091308)

The Journal retracts the article entitled “Gyrotactic Motile Microorganisms Impact on Pseudoplastic Nanofluid Flow over a Moving Riga Surface with Exponential Heat Flux” [1], cited above. Following publication, the publisher was made aware of several errors identified in the parameters and equations presented in the article. Adhering to our complaint’s procedure, an investigation was conducted by the Editorial Office, which confirmed multiple errors in the mathematical formulation of the complex heat and mass transfer problem presented in the paper. Given the scale of the errors and their impact on the validity of the overall findings, the Editorial Board have decided that a correction would not appropriately address the issues. Consequently, the Editorial Board have decided to retract this article [1] as per MDPI’s retraction policy (https://www.mdpi.com/ethics#_bookmark30). This retraction was approved by the Editor-in-Chief of the journal Crystals. The authors did not agree to this retraction.
