The National Science Foundation (NSF) is offering a federal grant opportunity titled "Interfacial Engineering," aimed at supporting fundamental research on atomic- and molecular-scale interfacial phenomena and the engineering of interfacial properties, processes, and materials. The program encourages innovative proposals that address long-standing challenges or emerging research areas in chemical and biochemical processes, with a focus on improving efficiency and resource utilization in industrial applications. With an estimated total program funding of $3,200,000 and an expected 113 awards, proposals are accepted on a rolling basis, and interested applicants can reach out to NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
