Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Magnetic Domain Texture in Fe3O4 Thin Films on SiO2 Nanospheres
Fe3O4 thin films grown on ordered SiO2 nanospheres form curved nanocaps with 3D geometry, inducing magnetic domain texture. X‐ray spectromicroscopy (XMCD‐PEEM), cross‐sectional electron microscopy (STEM), and polarized grazing‐incidence small‐angle neutron scattering (GISANS) reveal how topography modulates magnetization.

Advanced Porous Materials for Maritime Carbon Capture
Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.

Handed Magnon Propagation in Easy‐Axis Antiferromagnetic α‐Fe2O3
Coherent excitation and detection of handed magnons are achieved in the easy‐axis antiferromagnet α‐Fe2O3. An external magnetic field lifts the degeneracy between left‐ and right‐handed magnons without affecting their propagation velocity. The Dzyaloshinskii–Moriya interaction and anisotropy modulate their amplitude and damping, enabling intrinsic ...

Scalable bottom‐up fabrication of Fe3O4 nanodots on Nb:SrTiO3 using anodic alumina templates enables long‐range ordered arrays with diameters down to 30 nm. STEM highlights the epitaxial growth of Fe3O4 films on Nb:SrTiO3. Complementary polarized neutron reflectometry (PNR) and X‐ray magnetic circular dichroism (XMCD) measurements on continuous films ...

Pressurized gases reduce interfacial tension (IFT) at the gas‐liquid interfaces, their influence on the liquid–liquid interfaces remains unclear. For model compounds methane, water, and p‐xylene, neutron imaging observation of pressurized three‐phase systems is combined with Molecular Dynamics simulations.

Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to
