Retraction Note: Insights in the synthesis and electrochemical performance of tin tailings/grapheme derived from rice husk/polyester composite electrode materials for supercapacitors (The International Journal of Advanced Manufacturing Technology, (2023), 128, 3-4, (1879-1888), 10.1007/s00170-023-11967-0)

The Editor-in-Chief has retracted this article. A number of image integrity issues were raised by a third party, between this article and several articles published before or under consideration at the same time. Specifically: Figure 3 of this article appears to overlap with figure 1 in a previously published paper with some shared authors [1] presenting electrodes made of different materials. Figure 9b appears to overlap with figure 5a in two papers under consideration at the same time [2, 3]. Figure 9c appears to overlap with figure 2a in [4], and to figure 3a in [5] presenting different materials. Figure 9 d appears to overlap with figure 2a in [6], presenting different materials. Figure 3 of this article appears to overlap with figure 1 in a previously published paper with some shared authors [1] presenting electrodes made of different materials. Figure 9b appears to overlap with figure 5a in two papers under consideration at the same time [2, 3]. Figure 9c appears to overlap with figure 2a in [4], and to figure 3a in [5] presenting different materials. Figure 9 d appears to overlap with figure 2a in [6], presenting different materials. The Editor has lost confidence in the data and conclusions of this article. Author Victor Sunday Aigbodion disagrees with this retraction. Authors Okeke Chibuike Livinus, Egoigwe Vincent Sochima and Eneh Nnenna Joy have not responded to correspondence from the publisher regarding this retraction.
