The Royal Society of Chemistry hereby wholly retracts this RSC Advances article due to evidence that the peer review process was manipulated.
An investigation has established that the acceptance of this article was based on a fake reviewer report. The named reviewer does not have access to the email address used and they confirmed that they did not submit the report. Our investigation has found that the report was written and submitted by the last author. We have therefore concluded that the peer review process for this paper was compromised.
The other authors were not aware of, did not participate in, and did not authorise any irregularities in the peer review process. All co-authors were informed of the decision to retract this article. M. M. Alam did not respond to any correspondence and the other authors disagree with the decision to retract.
