Article Processing Charges
Why do Science Publishing Group journals have article processing charges?
Traditional journals are solely based on a reader-pays model, in which institutional libraries typically pay for the access to content. However, all journals published by Science Publishing Group (SciencePG) are full open access. The scientific community and general public can access all articles published in the journal for free.
This means that Science Publishing Group does not gain any income through selling subscriptions of the printed or online versions of the published articles. Therefore, by collecting Article Processing Charges from authors’ institutes or research funding bodies, Science Publishing Group is able to cover the various publishing services:
●  Editorial work: peer review, administrative support, commissioning content, journal development.
●  Technical infrastructure and innovation: development, maintenance and operation of online journal system and websites.
●  Production of articles: formatting and mark-up of articles and inclusion in indexing services.
●  Marketing of journal and content: making sure readers and authors know about the work published in the title.
●  Customer service: responding to authors and readers.

For more details, please contact with the editor directly once the manuscript is accepted.

Who is Responsible for Paying the Article Processing Charges?
Upon an article is editorially accepted, the corresponding author will be notified about the payment issue, which is charged to either the author, or the funder, institution or employer.
When and How do Authors Pay?
The submitting author needs to arrange payment of the article-processing charge unless a waiver has been granted. Following peer review, once a manuscript has received editorial acceptance in principle, the article-processing charge becomes payable and formatting checks on the manuscript will commence. Once formatting checks are completed, and payment of the article-processing charge has been received, the article will be published.
