This article has been withdrawn as part of the withdrawal of the Proceedings of the International Con-ference on Emerging Trends in Materials Science, Technology and Engineering (ICMSTE2K21). Sub-sequent to acceptance of these Proceedings papers by the responsible Guest Editors, Dr S. Sakthivel, Dr S. Karthikeyan and Dr IA Palani, several serious concerns arose regarding the integrity and vera-city of the conference organisation and peer-review process. After a thorough investigation, the peer-review process was confirmed to fall beneath the high standards expected by Materials Today: Proceedings. The veracity of the conference also remains subject to serious doubt and therefore the entire Proceed-ings has been withdrawn in order to correct the scholarly record. ⇑Corresponding author.
