Non‐destructive orientation tracking of individual β‐Sn grains in die‐attach solder joints
Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 617-631, May 2026.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 ...

Acta Crystallographica Section D, Volume 82, Issue 5, Page 504-515, May 2026.Radiation‐induced changes during X‐ray crystallographic data collection can compromise concurrent spectroscopic studies. Suitable protocols to detect and identify spectral artefacts from crystallization buffers and cryoprotectants are essential for the reliable analysis of chromophoric ligands in macromolecules.Online UV–Vis absorption spectroscopy is ...

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.ABSTRACT Ergot alkaloids (EAs), toxic secondary metabolites produced by Claviceps purpurea, pose food and feed safety concerns for cereal grains, particularly rye and wheat. While EAs are most frequently associated with rye, their occurrence in other cereals has been increasingly reported across diverse regions.

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1656-1679, May 2026.ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...
