Abstract Three-dimensional (3D) imaging of thin, extended specimens at nanometer resolution is critical for applications in biology, materials science, advanced synthesis, and manufacturing. One route to 3D imaging is tomography, which requires a til

Abstract Bimetallic nanoparticle (NP) catalysts are widely used in many heterogeneous gas‐based reactions because they often outperform their monometallic counterparts. During these reactions, NPs often undergo structural changes, which impact thei

Phase transitions in crystals are challenging to study with atomic resolution. Here, the authors reveal that the transition from fcc to bcc occurs across a few-atoms-wide coherent interface, which serves as a precursor phase for the nucleation of the

Atomic-scale insights into how a nanoparticle surface reconstructs under reaction conditions and the impact of the reconstruction on catalytic activity are still lacking. Here the authors reveal that Pd nanocatalysts display oscillatory changes in bo

Abstract Although transition metal phosphide electrocatalysts display unique electronic structure that serves as functional centers for hydrogen evolution reaction, the synthesis of this class of materials for oxygen evolution remains a challenge due

Abstract In bimetallic heterostructured nanoparticles (NPs), the synergistic effect between their different metallic components leads to higher catalytic activity compared to the activity of the individual components. However, how the dynamic changes

How nanoparticle (NP) catalysts re-structure under reaction conditions and how these changes associate with catalytic activity remains poorly understood. Here, the authors present operando TEM studies of Pd NPs during CO oxidation, which show reversi

At elevated temperatures, bimetallic nanomaterials often change their composition and morphology due to the interdiffusion of atomic species, which can affect their properties. Here, the authors use in situ transmission electron microscopy to provide

Hollow nanoparticles can be synthesized by galvanic replacement or the Kirkendall effect, which are generally regarded as two separate processes. Here, the authors use liquid TEM to follow the entire galvanic replacement of Ag nanocubes, finding expe
