ACS Omega, published by the American Chemical Society (ACS), is a prominent open-access, peer-reviewed journal dedicated to the rapid dissemination of original research across the entire breadth of the chemical sciences and related interdisciplinary fields. With an ISSN of 2470-1343, the journal covers a comprehensive scope that includes fundamental and applied chemistry, materials science, nanoscience, chemical engineering, biochemistry, and environmental science. It serves as a versatile platform for high-quality work that may not fit neatly into more specialized ACS publications, thereby fostering cross-disciplinary innovation. The journal primarily publishes full-length research articles, along with comprehensive reviews, perspectives, and technical notes, all of which undergo rigorous peer review. Its target audience is broad, encompassing academic researchers, industrial scientists, engineers, and graduate students seeking accessible, high-impact findings from diverse chemical disciplines. A defining feature of ACS Omega is its fully open-access model, ensuring that all published content is freely available to readers worldwide, which enhances visibility and citation potential for authors. As of 2026, the journal holds an Impact Factor of 5.2000 and is classified within the JCR Q2 quartile, reflecting its solid standing in the competitive landscape of chemistry journals. While it does not occupy the highest tier, its robust impact factor and rapid publication timeline, combined with the prestige of the ACS publisher, make it a reputable and increasingly popular venue for disseminating significant, reproducible research to a global audience.
