Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1763-1787, August 2026.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

Effect of Inter-Pass Temperature and Time on Martensite Formation in the Heat-Affected Zone During Multi-Pass Welding of P91 Steel

Metals
Dilatometry was used to simulate and analyze martensite formation in the grain-coarsened heat-affected zone (GCHAZ) of P91 steel for high inter-pass temperatures during multi-pass welding.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Hidden Complexity in Stress‐Induced Phase Transformations of CeO2–ZrO2 Ceramics

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
Using atomistic simulations, this study reveals that the tetragonal‐to‐monoclinic transformation in zirconia is more complex than previously thought. While pure bulk zirconia often becomes trapped in metastable phases, ceria doping and free surfaces facilitate the transformation into the stable phase, aligning with experimental data.

A Proof of Principle for the Phase‐Dependent Electrocatalytic Activity of NiTi Shape Memory Alloys for the Oxygen Evolution Reaction

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
We compare martensitic (Ni50Ti50) and austenitic (Ni51.2Ti48.8) NiTi shape memory alloys at room temperature as oxygen evolution reaction (OER) anodes, demonstrating that phase‐dependent microstructure governs electronic conductivity, surface roughness, and wettability.

Electronic Structure Effects During Cooperative Phase Transitions in Organic Semiconductor Single Crystals

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
A cooperative phase transition in the organic semiconductor ditBu‐BTBT crystal around 70°C reorganizes molecular structure and dynamics, altering its electronic properties. Soft x‐ray reflectivity and optical spectroscopy reveal shifts in electronic resonances and a widening of the optical bandgap. The transition reduces intermolecular interactions and
