Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

The application of neutron imaging to examine ethene hydrogenation over a carbon-supported palladium catalyst

Scientific Reports
The combination of a heterogeneous catalyst operating within a defined reactor comes within the domain of reaction engineering, which takes cognisance of combined roles for both the catalyst and the reactor to define the overall operational system.

Outstanding TC Enhancement in 5d–3d Y2NiIrO6 by Compression

Advanced Science, EarlyView.
Double perovskite Y2NiIrO6 with half filed 3d eg–5d t2g configuration, exhibits first experimental example of pressure‐enhanced magnetic interaction in iridate and iridate‐related systems. Its Curie temperature increase from 192 to 243 K at 17 GPa. Herein, the orthogonal eg–t2g pathway remains robust even under compression‐induced lattice distortion ...

Wide Temperature Zero Thermal Expansion in Al Matrix Composites with High Thermal Conductivity

Advanced Science, EarlyView.
Strain engineering strategy is implemented on the negative thermal expansion (NTE) phase Zn1.6Mg0.4P2O7 within composites, where Al matrix‐induced compressive strain drives uniform polyhedral and unit cell evolution, thereby enabling broad and consistent thermal compensation efficacy and obtaining good thermal performance.

Quantifying Magnetic Anisotropy of Ferroelectric Fe(II) Square‐Pyramidal Systems Using Torque Magnetometry

Advanced Science, EarlyView.
Five‐coordinate, square‐pyramidal Fe(II) complexes adopting polar, non‐centrosymmetric crystal structures exhibit exceptionally large easy‐axis magnetic anisotropy. Ligand‐driven distortions critically control the anisotropy, and the dielectric, Polarization vs Elecric field and piezo response studies confirm intrinsic polarization, positioning these ...

Atomically Modulating Competing Exchange Interactions in Centrosymmetric Skyrmion Hosts GdRu2X2 (X = Si and Ge)

Advanced Electronic Materials, EarlyView.
Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.
