Motion of nanodroplets near edges and wedges
arXiv:cond-mat/0609424 · doi:10.1103/PhysRevLett.97.236101
Abstract
Nanodroplets residing near wedges or edges of solid substrates exhibit a disjoining pressure induced dynamics. Our nanoscale hydrodynamic calculations reveal that non-volatile droplets are attracted or repelled from edges or wedges depending on details of the corresponding laterally varying disjoining pressure generated, e.g., by a possible surface coating.
