Retraction Note: Multifaceted incorporation of epoxy/functionalized maize cob nanoparticle with biosynthesis silver nanoparticles for composite coating of mild steel (The International Journal of Advanced Manufacturing Technology, (2024), 130, 3-4, (1465-1476), 10.1007/s00170-023-12793-0)

The Editor-in-Chief has retracted this article. A number of image integrity issues were raised by a third party, in different articles sharing some of the same authors, either published earlier or under consideration at the same time. Specifically: A panel in Figure 1 appears to be similar to a number of panels in different articles, sometimes depicted with different spectra. This includes Figure 2 of [1], Figure 1 of [2], Figure 1 of [3], Figure 6 of [4], Figure 2 of [5], Figure 2 of [6]. Figure 4 appears to overlap with Figure 2 in [7], Figure 3a in [8] and Figure 2 in [9]. Figure 7 appears to overlap with Figure 7 in [10] and Figure 13 in [11]. Figure 11c appears to overlap with Figure 5b of [12] with editing, showing different samples.
