This study was retracted due to duplicate figures, specifically panels PAM and SAG, which were previously published in other journals. This constitutes a misuse of the scientific publishing system.
Area of Science:
- Polymer Science
- Materials Science
- Scientific Publishing Ethics
Background:
- Figures within the article, specifically panels PAM, SAG, and CMS-g-PAM (M) of Figure 1, were found to be non-original.
- Panel PAM from Figure 1 showed similarities to figures in previously published works in the International Journal of Biological Macromolecules and Carbohydrate Polymers.
- Panels SAG and SAG-g-PAM (M) from Figure 1 were similar to figures in a publication in the Journal of Applied Polymer Science.
Purpose of the Study:
- To address concerns regarding the originality of figures presented in the publication.
- To uphold the integrity of scientific publishing and ensure proper citation of previously published data.
Main Methods:
- Comparative analysis of figures from the current article with those from previously published research.
- Investigation of potential duplicate or reused imagery in scientific figures.
Main Results:
- The article has been officially retracted by the Editor-in-Chief.
- Significant overlap and similarity were identified between figures in this article and figures from multiple prior publications by the same authors.
- The identified issues indicate a violation of the policy requiring original and uncited material.
Conclusions:
- The article represents a misuse of the scientific publishing system due to the reuse of figures without appropriate citation.
- The journal apologizes to its readers for the failure to detect these issues during the submission process.
- Retraction serves to maintain scientific integrity and prevent the dissemination of misleading or unoriginal research.
