“…To explore the factors affecting microparticle size, we performed the following experiments. The diameter of the microparticles was investigated by adjusting the voltage (4, 5, 6, 7, and 8 kV), the concentration of ALG (1, 1.5, 2, 2.5, and 3%), the outlet diameters of the capillary (50,100,150,200, and 250 μm), and the flow rate (0.5, 1, 2, 4, and 8 mL/h). All of the diameter measurements and observations were performed under a stereo microscope.…”
