Atomic Resolution Observations of Nanoparticle Surface Dynamics and Instabilities Enabled by Artificial Intelligence
Peter A. Crozier, Matan Leibovich, Piyush Haluai +9
Nanoparticle surface structural dynamics is believed to play a significant role in regulating functionalities such as diffusion, reactivity, and catalysis but the atomic-level proc…
The role of surface spin polarization on ceria-supported Pt nanoparticles
Byungkyun Kang, Joshua L. Vincent, Peter A. Crozier +1
In this work, we employ first-principles simulations to investigate the spin polarization of CeO-(111) surface and its impact on interactions between a ceria support and Pt nan…
An Light Illumination System for an Aberration-Corrected Environmental Transmission Electron Microscope
Qianlang Liu, Barnaby D. A. Levin, Diane M. Haiber +2
In this work, an optic fiber based illumination system integrated into an aberration-corrected environmental transmission electron microscope (ETEM) is designed,…
Fluxional Behavior at the Atomic Level and its Impact on Activity: CO Oxidation over CeO-supported Pt Catalysts
Joshua L. Vincent, Peter A. Crozier
Reducible oxides are widely used catalyst supports that can increase oxidation reaction rates by transferring their lattice oxygen at the metal-support interface. The interfacial o…
Developing and Evaluating Deep Neural Network-based Denoising for Nanoparticle TEM Images with Ultra-low Signal-to-Noise
Joshua L. Vincent, Ramon Manzorro, Sreyas Mohan +6
A deep convolutional neural network has been developed to denoise atomic-resolution TEM image datasets of nanoparticles acquired using direct electron counting detectors, for appli…
Chemical Kinetics for Operando Electron Microscopy of Catalysts: 3D Modeling of Gas and Temperature Distributions During Catalytic Reactions
Joshua L. Vincent, Jarod W. Vance, Jayse T. Langdon +2
environmental transmission electron microscopy (ETEM) is a powerful tool for observing structural modifications taking place in heterogeneous catalysts under rea…
