Interfacial Transport Phenomena: in Memory of Prof. Paul Steen (1952-2020)

This npj Microgravity Collection is dedicated to the memory of the late Professor Paul Steen who served as an Associate Editor for the journal, and was renowned for his work in interfacial fluid mechanics. This Collection aims to provide insight into the wider field of interfacial transport phenomena, with relevance to gravitational effects.

Additional articles for this Collection are under consideration at the journal and will be published when ready.

All articles have undergone npj Microgravity's standard peer review process and have been subject to all of the journal’s standard policies. This includes the journal’s policy on competing interests. The Editors declare no competing interests with the submissions which they have handled through the peer review process. The peer review of any submissions for which the Editors have competing interests is handled by another Editorial Board Member who has no competing interests.
