The Journal of Membrane Science provides a focal point for academic and industrial chemists, chemical engineers, materials scientists, and membranologists working on membrane systems.The journal publishes original research and reviews on membrane transport, membrane formation / structure, fouling, module / process design, and processes / applications.Primary emphasis is on structure, function, and performance of non-biological membranes; papers bridging the gap with biological membranes are also appropriate.The Journal of Membrane Science publishes Full Text Papers, State-of-the-Art Reviews, Letters to the Editor, and Perspectives.Reviews: should not only summarize the key research contributions in a field, they should also provide critical evaluation of the scientific literature. Review papers are intended to provide archival guidance and direction for the broad membrane community and are thus held to the highest standard for publication.Perspective articles: should provide a focused discussion of an important area of membrane science and technology, emphasizing recent developments, future challenges, and/or new opportunities. Perspective articles will be by invitation only, and they will be reviewed by at least one Editor of the Journal and one member of our Advisory or Editorial Board.
