Retraction note: Unveiling the empirical models for estimating insulating properties of epoxy/CaCO3 derived from snail shell biocomposite (The International Journal of Advanced Manufacturing Technology, (2023), 129, 3-4, (1901-1913), 10.1007/s00170-023-12379-w)

The Editor-in-Chief has retracted this article. A number of image integrity issues were raised by a third party, specifically: Figure 1 of this article and Fig. 1 of three earlier articles by the same author [1, 2–3] were found to overlap, despite describing different materials. Figure 9b was found to overlap with Fig. 10 of another article by the same authors [1] and with a panel of Fig. 2 in a previously published paper by different authors [4] illustrating different materials. Figure 10 was found to overlap with Fig. 10 of [2] and Fig. 11 of [3]. Significant overlap was found between this paper and the aforementioned paper by the same authors [1], under consideration at the same time. The authors have not responded to correspondence from the publisher regarding this retraction.
