RETRACTION: H. Mahdavi, F. Khademi, A. A. Heidari and M. Karami, “ Fabrication of Mixed Matrix Polyphenylsulfone-Polysulfone Blend Membranes Incorporated With Nickel/Hydrazine@silica Core-Shell Nanoparticles Using VIPS-NIPS Method for Efficient Dye Rejection,” Journal of Applied Polymer Science 140, no. 42 (2023): e54564, https://doi.org/10.1002/app.54564.

The above article, published online on 16 August 2023 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Stefan Spiegel; and Wiley Periodicals, LLC. The retraction has been agreed upon due to unexpected similarities observed within the spectra presented in Figures 2 and 3. Furthermore, there are several instances of duplication of elements identified in Figure 4a-d. Finally, scientific discrepancies were identified in Figure S5. The authors collaborated with the investigation and stated that the images for Figure S5 were obtained from an external laboratory. However, due to the nature and extent of the concerns raised, the editor has lost confidence in the results and conclusions presented in this study. The authors were informed of the retraction.
