Experimental study demonstrates material-dependent nanoparticle formation during spark ablation in pure nitrogen, indicating precursor reactivity governs nitride versus oxide output.
Spark ablation in pure N 2 produces material-dependent nanoparticles: Ti and Al form nitride/oxide mixtures, Mg only oxides, and Pd metallic NPs.
