Harnessing diamond surface features for dense and aligned NV ensembles
Eveline Postelnicu, Lillian B. Hughes Wyatt, Tri Nguyen +6
Controlling nitrogen doping in diamond is key to advancing nitrogen-vacancy (NV) center devices. We harness the hillock, a typically undesirable surface feature, to incorporate hig…
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…
In situ Gas-Cell Electron Microscopy Reveals Pressure-Selected Restructuring Pathways in AuRu Ammonia Catalysts
Amy S. McKeown-Green, Parivash Moradifar, Zisheng Zhang +7
Bimetallic catalysts provide new routes toward sustainable ammonia synthesis, but the nanoscale structural dynamics under reaction-relevant conditions remain poorly understood. Her…
Missing Wedge Inpainting and Joint Alignment in Electron Tomography through Implicit Neural Representations
Cedric Lim, Corneel Casert, Arthur R. C. McCray +4
Electron tomography is a powerful tool for understanding the morphology of materials in three dimensions, but conventional reconstruction algorithms typically suffer from missing-w…
