SEM photographs of aligned nanofibers fabricated via MES with ((a), (c), (e), and (g)) and without Fe₃O₄ nanoparticles ((b), (d), (f) and (h)) at the voltage of 15 kV and the flow rate of (a), (b) (0.6 mL/h); (c), (d) (0.9 mL/h); (e), (f) (1.2 mL/h); (g), (h) (1.8 mL/h). The inserts in (g) and (h) were the FFT patterns of (g) and (h) respectively.
