Why Pay an Article Processing Charge?
Different from the traditional access mode of journals, which is paid by readers or libraries, all published journals of 4D Publishing Group are open access, and readers can review your research content for free without purchase. In order to ensure the normal operation and maintenance of the publishing group, we need to charge authors for article processing fees to providing corresponding services and to maximize the dissemination of your research.
How Much to Pay?
Authors are required to pay an article processing charge (APC) of $470 US dollars per published paper. There are no surcharges based on the length of an article, figures or supplementary data.
We only accept payment in USD.
