Probing three-dimensional structures of complex colloidal quantum dots at the single-atomic level
Qikai Wu, Meng Pei, Jiancheng Zhang +6
Colloidal quantum dots (QDs) are promising optoelectronic materials due to their size-tunable properties, yet their three-dimensional (3D) quantum confinement makes electronic stat…
Mapping Order in Semicrystalline Polymers using Machine Learning of Nanobeam Electron Diffraction
Nicholas Marchese, Arthur R. C. McCray, Yael Tsarfati +4
Organic mixed ionic electronic conductors (OMIECs) are a promising class of polymer materials for applications spanning neuromorphic computation to energy efficient electronics and…
Hydration-controlled twist forms a moiré glass in charge-frustrated layered silicates
Juhyeok Lee, Piotr Zarzycki, Colin Ophus +5
Twisting layered materials produces moiré superlattices, but prescribed twist angles are usually obtained by demanding assembly procedures. Here we show that montmorillonite, an a…
Visualizing Degradation in Anode-Free High-Utilization Aqueous Batteries Across Cell Lifetime
Sofia K. Catalina, Kyle Frohna, Willow Thompson +6
Operando microscopy has unveiled key mechanistic insights in battery materials during early cycling, but long-term characterization to unveil material evolution, degradation, and f…
Plasmonic Photocatalysis Enables Selective Oxidative Coupling of Methane with Nitrous Oxide under Ambient Conditions
Serin Lee, Lin Yuan, Elijah Begin +8
Methane (CH4) and nitrous oxide (N2O) are potent greenhouse gases that represent substantial chemical energy. Conversion of these abundant waste gases to high-value chemicals typic…
Unsupervised segmentation and clustering workflow for efficient processing of 4D-STEM and 5D-STEM data
Serin Lee, Stephanie M. Ribet, Arthur R. C. McCray +3
Four-dimensional scanning transmission electron microscopy (4D-STEM) enables mapping of diffraction information with nanometer-scale spatial resolution, offering detailed insight i…
