Mo₃Ni₂N Nanoparticle Generation by Spark Discharge. [PDF]

Materials (Basel), 2023
Spark ablation is an advantageous method for the generation of metallic nanoparticles with defined particle sizes and compositions. The reaction of the metal particles with the carrier gas during the synthesis and, therefore, the incorporation of those light elements into structural voids or even compound formation was confirmed for hydrides and oxides
