Benefits for reviewers with MDPI. The benefits for reviewers are sometimes things that are not clear at first glance. Peer review is basically a public service and so there is no money to be made by doing it. But the peer review process is really important to us here at MDPI. MDPI applies a rigorous editorial process, including multiple subject and language checks. All manuscripts are carefully evaluated through a single-blind peer review process. A guide for authors and other relevant information for submitting manuscripts are available on the Instructions for Authors page. Processes is a monthly international open access, peer-reviewed journal published by MDPI.
