Centerline Placement and Alignment of Anisotropic Nanotubes in High Aspect Ratio Cylindrical Droplets of Nanometer Diameter

High aspect ratio cylindrical droplets of carbon-nanotube solutions present interesting hydrodynamic flow patterns during evaporation, where particles are aligned and positioned. The flow inside droplets with diameters <1000 nm positions all the nanotubes along the droplet centerline with 95% precision, while droplets with diameters >3µm align the nanotubes along the droplet edges during evaporation.
