This article has been proven to be a duplicate of another publication.
The manuscript was submitted to the journal International Letters of Chemistry, Physics and Astronomy (ILCPA) after it had been published online in the journal Materials for Renewable and Sustainable Energy. Duplicate publication in any form is considered to be a publication malpractice. The previous management as well as former Editors-in-Chief of the journal could not explain the circumstances of publishing the article. Besides, the authors informed us that they were also not aware of the conditions which led to the duplicate publication and agreed to the retraction. Therefore, the article was subjected to retraction for the purpose of eliminating the duplicate publication in line with the Retraction Guidelines of the Committee on Publication Ethics.
The Editorial office of the journal would like to deeply apologize to authors of the article as well as to Prof. Kasim Uthman Isah for publication of the article in the past and any inconvenience caused thereby. The authors of have been informed about the decision to retract the article. Thus, the paper has been declared retracted and marked accordingly.
