Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

Advanced Materials, EarlyView.
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

Advanced Materials, EarlyView.
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.

What Is the Limit of Quantification for the Minor Phase in Time-of-Flight Neutron Diffraction? A Case Study on Fe and Ni Powder Mixtures at VULCAN

Crystals
A phase present in small quantities within materials may not simply serve as a secondary component; it can play a crucial role in determining the integrity, properties, and performance of the material.

The Virial Equation of State of Low-Density Neutron Matter

, 2005
We present a model-independent description of low-density neutron matter based on the virial expansion. The virial equation of state provides a benchmark for all nuclear equations of state at densities and temperatures where the interparticle separation ...

Handed Magnon Propagation in Easy‐Axis Antiferromagnetic α‐Fe2O3

Advanced Materials, EarlyView.
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 ...
