Figure 4: Particle size distribution (PSD) of nanoparticles created in this study. Images (a), (b) and (c) present the PSDs of silver, ruthenium and nickel nanoparticles, respectively, in the absence of ammonium nitrate; while (d), (e) and (f) are PSDs of silver, ruthenium and nickel nanoparticles in the presence of ammonium nitrate, respectively.
