Electrospray flow rate influenced the sized of functionalized soot nanoparticles

A common method in the synthesis of functionalized carbon particles such as laser ablation of graphite required time and complicated method. Therefore, electrospraying method was used to synthesize functionalized candle soot particles. Electrospraying method uses electric force to produce monodisper...
