Figure 3: Size comparison of nickel nanoparticles produced in the absence (a) and presence (b) of ammonium nitrate. Image (a) is a SEM image of nickel nanoparticles (246 nm) produced without ammonium nitrate, while image (b) is a TEM image of particle size distribution of nickel nanoparticles (9 nm) produced with ammonium nitrate. Both experiments were run at 1 0 4  M (precursor concentration), 700°C (operating temperature), and 5 W (atomizer power).
