MDPI publishes all its journals in full open access under a Creative Commons (CC BY) license. This allows the scientific community and the general public to gain unlimited, free and immediate access to scholarly articles. To cover the cost of publication, authors pay an article processing charge (APC) for manuscripts accepted after peer-review. There are no charges for rejected articles, no submission charges, and no surcharges based on the length of an article, figures or supplementary data. Editorial items (Editorials, Corrections, Additions, Retractions, Letters, Comments, etc.) are published free of charge.
