Capillarity publishes high-quality original research articles and current reviews on the fundamental scientific principles and innovations of capillarity in physics, chemistry, biology, environmental science, and related emerging fields. All advances in theoretical, numerical, and experimental approaches to capillarity, particularly in capillary tube and interface-dominated structures and systems, are welcome. The following topics are within (but not limited to) the scope of capillarity: 1) Capillary-driven phenomena in natural and artificial tubes, porous, and nanoporous materials 2) Fundamental mechanisms of capillarity aided by theory and experiments 3) Spontaneous imbibition, adsorption, wicking, and related applications of capillarity in hydrocarbon production, chemical processes, and biological sciences 4) Static and dynamic interfacial processes, surfactants, wettability, films, and colloids 5) New approaches and technologies in capillarity Capillarity is a quarterly open-access journal, free to read for all. The journal provides a communication platform for researchers interested in all fields of capillary phenomena.
