Article Title: Multiplexed electrospraying of water in cone-jet mode using a UV-embossed pyramidal micronozzle film

doi: 10.1038/s41378-022-00391-1

Figure Lengend Snippet: The main high voltage was applied to the water. The in-plane extractor was connected to switch 1 to identify the effect of electric concentration at the nozzle tip. A guide ring was connected to switches 2 and 3. Switches 2 and 3 were not connected simultaneously. Switch 2 was connected when switch 1 was disconnected. Switch 3 was connected when switch 1 was connected (the grounded in-plane extractor). The flow rate was controlled using a syringe pump. A DSLR camera or a high-speed camera was used for the visualization of the electrospray

Figure Lengend Snippet: a DSLR camera images in cone-jet mode (voltage at water: 1.6 kV, flow rate: 0.50 ml/h). b Onset and end voltages of the cone-jet mode. The data plotted in black lines with diamond symbols are the results when switch 2 depicted in Fig. was connected. The data plotted in green lines with triangle symbols are the results when switches 1 and 3 depicted in Fig. were connected. c Morphology of the Taylor cone and jet at voltages of 1.3 kV ( c-i ), 1.5 kV ( c-ii) , and 1.7 kV ( c-iii ) at a flow rate of 0.15 ml/h. The meniscus of the Taylor cone was compressed toward the nozzle as the applied voltage increased. d Operation domain of the steady cone-jet mode of water. The domains of the other research studies were replotted from the data provided in the references. The domain obtained using UV-embossed pyramidal micronozzles showed good agreement with the other domains obtained by the other types of micronozzles
