Finding Atomic Dynamics in Metal and Alloy Subnanometer Clusters

Abstract

This highlight review explains advanced structural analysis techniques utilizing electron microscopy to uncover various properties and phenomena in subnanometer clusters that were previously unknown in larger nanoparticles. The discoveries introduced the concept of “subnano alloying,” where different elements mix at the atomic level in arbitrary proportions, leading to enhanced catalytic performance. Additionally, the behavior and dynamics of these clusters were examined to gain insights into their stability and reactivity. These findings have significant implications for the design of advanced materials with tailored properties and improved catalytic applications.
