Dear Author, We received one revision and trying to find second reviewer. To this day we send request for 9 experts in this field (Including authors suggestions). They declined or ignored our invitations. We must search until someone agreed to take on this assignment. If you want to suggest someone else, you have to do it according to the following guidelines: Authors can suggest reviewers but they cannot be from the same institution as the authors, and at least one cannot be from the same country. With best regards,
Finding reviewers is often difficult. This is because most reviewers are not paid. Some journals solve this problem using adopting a single-blind review process instead of a double-blind review process.
Perhaps you can get some information from the following link:
