Mircomechanical insights into unconstrained grain boundary sliding
Divya Sri Bandla, Subin Lee, Christoph Kirchlechner
Grain boundary sliding (GBS) is a key deformation mechanism at high homologous temperatures in polycrystalline materials, however, its intrinsic behavior is often obscured by addit…

Redundant Cross-Correlation for Drift Correction in SEM Nanoparticle Imaging
Iago Bischoff Montenegro, Konrad Prikoszovich, Subin Lee +3
Scanning Electron Microscopy (SEM) is a widely used tool for nanoparticle characterization, but long-term directional drift can compromise image quality. We present a novel algorit…
