A surviving pink spinel records an early aluminous melt on the ureilite parent body
Yaozhu Li, Phil J. A. McCausland, Roberta L. Flemming +2
Ureilites are ultramafic achondrites interpreted as fragments of a differentiated parent body, yet their origin and evolution remain debated because textural equilibrium coexists w…
Subgrain-resolved Analysis of Degradation in Cu Metallization via Scanning 3DXRD and Thermomechanical Modeling
Nikhil Prabhu, Laura Neumann, Michael Reisinger +7
Metallization layers play a key role in the performance and reliability of modern power semiconductor devices. During short-circuit events, rapid heating of power metallization lay…
Diamond compound refractive lenses for high energy Dark Field X-ray Microscopy
Steffen Staeck, Can Yildirim, Frank Seiboth +4
Compound-refractive lenses (CRL) are a type of x-ray optics that find widespread applications as focusing and imaging lenses. The choice of material is one of the most defining pro…
Revealing 3D orientation and strain heterogeneity in calcite generated by bio-cementation
Marilyn Sarkis, James A. D. Ball, Michela La Bella +5
Bio-cementation uses bacterially induced calcite to bind sand grains, offering a low-carbon approach to soil stabilization. However, the 3D morphology, orientation texture, and int…
Remanent crustal strain on Mars in non-poikilitic olivine of NWA 7721
Yaozhu Li, Szilvia Kalácska, Szilvia Kalácska +6
We present a multiscale microstructural analysis of olivine from the non-poikilitic lithology of the poikilitic shergottite NWA 7721, using dark-field X-ray microscopy (DFXM), elec…
Bridging Grain Mapping and Dark Field X-ray Microscopy for Multiscale Diffraction Imaging
Aditya Shukla, Can Yildirim, James A. D. Ball +7
Resolving how defects emerge and interact within the hierarchical structure of polycrystalline materials remains a core challenge in materials science. Grain-mapping methods such a…
