A2: Surfaces and Interfaces

Surfaces and interfaces play a central and often governing role in micro- and nanoscale systems, where high surface-area-to-volume ratios amplify interfacial phenomena to dominate device behavior, transport processes, and material interactions. This section welcomes original research and review articles that advance the fundamental understanding of surfaces and interfaces in the context of micromachines, MEMS/NEMS, and micro/nanofluidic platforms. Topics of interest include, but are not limited to, wettability and superwettability, drop–surface interactions, capillary and interfacial forces, contact line dynamics, thin film coatings, surface functionalization and modification, bio-interfaces, active matter at surfaces and interfaces, liquid-infused surfaces, stimulus-responsive and adaptive surfaces, biomimetic interfaces, surface-mediated phase transitions, electrowetting, and micro/nanotribology. Experimental, theoretical, and computational contributions are encouraged.
