a–d Photographs of different steps in MUS. Scale bars, 5 cm. e The floating yield according to dropping height of liquid metal slurry(error bars: standard deviation). f Floating yield of the traditional method (dropwize adding) and MUS method according to the diameter of liquid metal particles(error bars: standard deviation.). g Floating yield of liquid metal particles based on different water soluble solvent (ethanol, acetone, n-methylpyrrolidone, n-dimethylformamide, isopropyl alcohol) and water insoluble solvent (hexane)(error bars: standard deviation.). h, i Time-lapse microscopic photographs of the liquid metal particles in the “material releasing” process taken at 0 °C and 25 °C, respectively. Scale bars, 500 μm. j Floating yield of liquid metal particles according to the temperature(error bars: standard deviation).
