Surface Segregation of Fe in Pt–Fe Alloy Nanoparticles: Its Precedence and Effect on the Ordered‐Phase Evolution during Thermal Annealing

Abstract The front cover artwork for Issue 22/2015 is provided by the Microscopy of Nanoscale Materials Research Group at McMaster University, Canada. The image depicts the marriage between in situ heating and advanced electron microscopy techniques that enabled this research team to track structural, compositional, and configurational evolution of the same alloy nanoparticle over the course of heat treatment.
