The U.S. National Science Foundation is an independent federal agency that supports science and engineering in all 50 states and U.S. territories. NSF was established in 1950 by Congress to promote the progress of science, advance the national health, prosperity and welfare, and secure the national defense.
The Particulate and Multiphase Processes program aims to support fundamental research on the physico-chemical phenomena that govern particulate and multiphase systems. This includes focusing on the flow of suspensions, drops and bubbles, granular and granular-fluid flows, behavior of micro- and nanostructured fluids, and the processes of self assembly and directed-assembly that involve particulates. The program seeks transformative research that enhances our basic understanding of these processes, with emphasis on how particle-scale phenomena influence the behavior and dynamics of larger-scale systems. It encourages research with clear visions of how results may impact advanced manufacturing, energy harvesting, biological transport systems, biotechnology, or environmental sustainability. Collaborative and interdisciplinary proposals, especially those combining experiment with theory or modeling, are encouraged. Research areas of interest include multiphase flow phenomena, particle science and technology, multiphase transport in biological systems, and interfacial transport. Proposals should highlight the novelty and transformative nature of the work, its importance in engineering science, and its potential societal or industrial impact. The program also supports various proposal types, including Faculty Early Career Development (CAREER), Conferences, Workshops, Supplements, Rapid Response Research (RAPID), EArly-concept Grants for Exploratory Research (EAGER), and Grant Opportunities for Academic Liaison with Industry (GOALI).
