Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Impact Plasma Amplification of the Ancient Mercury Magnetic Field
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Non‐destructive orientation tracking of individual β‐Sn grains in die‐attach solder joints
This study introduces inclined scanning three‐dimensional X‐ray diffraction microscopy (i‐S3DXRD) that enables three‐dimensional orientation mapping of planar polycrystalline materials, revealing the thermal fatigue mechanism of Pb‐free solder joints.Understanding the failure mechanisms of Pb‐free solder joints during thermal cycling is a critical ...

A setup for fielding high‐pressure samples contained in diamond anvil cells (DACs) at the LCLS X‐ray free electron laser is described and example powder X‐ray diffraction data are presented. Future prospects for experimental capabilities in DACs enabled by the LCLS, such as short pulse laser interactions and multiple pulse modes, are discussed.A novel ...

ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.
