ACS Applied Materials & Interfaces serves the interdisciplinary community of chemists, engineers, physicists and biologists focusing on how newly-discovered materials and interfacial processes can be developed and used for specific applications. The editors are proud of the rapid growth of the journal since its inception in 2009, both in terms of the number of published articles and the impact of the research reported in those articles. ACS AMI is also truly international, with the majority of published articles now coming from outside the United States, capturing the rapid growth in applied research around the globe.
