This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor. Unauthorised authorship changes were made when the revised version of this paper was submitted, following suggestions for relatively minor revisions from the reviewers and Guest Editor, with authors Balasubramaniam Saravanakumar, Mehboobali Pannipara and Abdullah G. Al-Sehemi being added to the paper. No satisfactory explanation was given for this change, nor was it approved by the editor. This authorship change breaches the policies of the journal and as a result, the editors no longer have confidence in this paper and are retracting it. The journal apologises for not having identified the problematic authorship change during the review process and for any resulting inconvenience. Following separate concerns raised on PubPeer (https://pubpeer.com/publications/3312F3F1460199AE9E813A07BED8DD) regarding the authenticity of the FT-IR data in the paper, the editor carefully inspected the raw data (both SPA and excel files) and found no clear sign of image/data manipulation and therefore has no reason to doubt the validity and veracity of the presented FT-IR data in Figure 2.
