ACS Omega is not rated in the top 15% of its subject areas by Scopus in their most recent ratings, and so it is not eligible for payment in the KU OA project.
Publishing in an Open Access journal with ACS does not affect the basics of the publication process. An author must still submit their paper to a journal and it must still be accepted and pass the usual process of editing and peer review. The main difference comes when the article is submitted for publication: The author notifies ACS that the university may pay the Article Publishing Charge (APC) which is required as part of the OA process.
As of July 2023, there are 42 journals published by ACS that meet all the guidelines as set by the university administration. You can see the list of these journals in either Excel format or PDF format here.
At any point, authors can use the ACS Publication Center to learn more about ACS publishing, find information about manuscript preparation and submission, the ACS Style Guide, and Open Access publishing at ACS.
You can also find the list of all ACS journals here (PDF format, Excel Format).
