Figure 3From: Nearly Monodispersion CoSm Alloy Nanoparticles Formed by an In-situ Rapid Cooling and Passivating Microfluidic ProcessThe near monodispersion CoSm alloy nanoparticles synthesized by the microfluidic reactors.a The Co5Sm nanoparticles collected under room temperature show ellipsoidal or spherical shape with broad size distribution of 5.1 ± 0.8 nm.b The as-synthesized Co5Sm nanoparticles, cold quenched, mostly show nonspherical shape and uniform size of 4.8 ± 0.4 nm.c The SAED of CoSm alloy nanoparticles show dispersed rings, suggesting an amorphous phase.d The EDS spectrum of the CoSm alloy nanoparticles indicates alloy composition reaching the intended stoichiometry (Co/Sm = 5:1)Back to article page
