Outline of Final Research Achievements

This study relates to a propulsion mechanism which drives by surface tension gradient on aqueous surface caused by spreading of ionic liquids (ILs). Propulsion force and its time are determined by surface activity of ILs and dissolution speed of ILs in water, respectively. Propulsion force increased with nozzle width and decreased with nozzle length. Propulsion time decreased with nozzle width and increased with nozzle length. Dripping of imidazolium ILs on aqueous surface caused spreading which advanced circularly. Its radius obeyed a power-law with respect to time. Periphery of the spreading area was disturbed with time causing periodic unevenness. The disturbance increased with time and was more periodic in ILs with longer alkyl chain. The number of the unevenness decreased with time and increased with alkyl chain length. Application of magnetic field on aqueous solution of a magnetic IL caused a convection on the surface implying a possibility of magnetic control of the propulsion.
