This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Editor in Chief. An investigation identified violations of the journal's policies on authorship and conflict of interest related to the submission and review of this paper. Authorship changes were made during the revision of this paper. Three authors were added at the paper's first revision stage (Shams Forruque Ahmed, Dong Nguyen Van, Phuoc Quy Phong Nguyen). Two authors were added at the paper's second revision stage (Tuan Hai Nguyen, Thanh Hai Truong). One author was subsequently removed at the second revision stage despite having been added at the first revision stage. These changes were made without validation or authorisation. This breached the journal's policy on authorship. In addition, the review of this paper was handled by Editor Anh Tuan Hoang, who has a record of collaboration, including co-publication, with 6 of the authors (Thanh Hai Truong, Van Viet Pham, Van Nhanh Nguyen, Shams Forruque Ahmed, Prabhakar Sharma, Zafar Said). A number of these co-authored papers were under consideration at the same time as this paper was undergoing review for FUEL. Additionally, acceptance of the article was partly based upon the positive advice of 3 reviewers who were closely linked with one of the authors (Zafar Said); and also partly based upon the positive advice of 3 reviewers who were closely linked with the handling editor.The Corresponding (and other) Authors responded promptly to requests for clarification on these points, but those explanations did not satisfactorily address the concerns. As such and due to the nature of the irregularities uncovered, the Editor has lost confidence in the validity/integrity and findings of the article and decided to retract the article. The scientific community takes a very strong view on this matter and apologies are offered to readers. The Authors do not agree with the decision to retract the paper and dispute the grounds for it.
