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…
PhaseT3M: 3D Imaging at 1.6 Ã Resolution via Electron Cryo-Tomography with Nonlinear Phase Retrieval
Juhyeok Lee, Samuel W. Song, Min Gee Cho +5
Electron cryo-tomography (cryo-ET) enables 3D imaging of complex, radiation-sensitive structures with molecular detail. However, image contrast from the interference of scattered e…
Atomic-scale 3D structural dynamics and functional degradation of Pt alloy nanocatalysts during the oxygen reduction reaction
Chaehwa Jeong, Juhyeok Lee, Hyesung Jo +6
Pt-based electrocatalysts are the primary choice for fuel cells due to their superior oxygen reduction reaction (ORR) activity. To enhance ORR performance and durability, extensive…
Advancing atomic electron tomography with neural networks
Juhyeok Lee, Yongsoo Yang
Accurate determination of three-dimensional (3D) atomic structures is crucial for understanding and controlling the properties of nanomaterials. Atomic electron tomography (AET) of…
