Temperature-Driven Phase Transition and Element Segregation in Pd-Ru Nanoparticles

Bimetallic alloys can form three typical structures, including solid solution, heterogeneous structure, and intermetallic compounds, depending on the interactions between identical and different atoms. Although this trend can be predicted through the types of binary phase diagrams, different synthesis methods can trap the system in various dynamical intermediates between these three typical structures. Here, we … Read more
