Abstract:	We report that high density monodisperse liquid particles (2um diameter oil-droplets) self-organize to 3D close-packed face-centered cubic arrangements, when flowing together with water (continuous) phase in a microchannel (10um×100m or 10m×50um). The resulting remarkably rigid and stable close-packed structure exhibits itself in square and hexagonal patterns, depending on the specific flow conditions. Generally, we observe two (coexisting) ‘crystallographic’ orientations of the close-packed structure, and distinguish dislocation lines and defects.
