The authors wish to remove Reference 15 from the published manuscript. This reference was inadvertently retained in the final version of the article. At the time of initial drafting, the cited book appeared as a forthcoming title on the RSC Web site; however, the authors were ultimately unable to obtain a copy, and the publisher has since confirmed that the book was never published. The reference was originally included as a potential supplemental resource for readers, but it does not substantively support any claims made in the article. Its removal does not affect the integrity or conclusions of the work.
The sentence at the end of the sixth paragraph, “In-depth discussions of DoE methodology and the statistical principles behind the approach are available in other resources in greater detail and are outside the scope of this discussion.1,2,15–17”, should be updated as follows:
“In-depth discussions of DoE methodology and the statistical principles behind the approach are available in other resources in greater detail and are outside the scope of this discussion.1,2,16,17”
Reference 15 should be removed from the References list.
