Large scale synthesis of copper nickel alloy nanoparticles with reduced compressibility using arc thermal plasma process

Abstract Among the various methods employed in the synthesis of nanostructures, those involving high operating temperature and sharp thermal gradients often lead to the establishment of new exotic properties. Herein, we report on the formation of Cu-Ni metallic alloy nanoparticles with greatly enhan...
