Anisotropic Band-Split Magnetism in Magnetostrictive CoFe2O4

Single crystal spinel CoFe₂O₄ exhibits the largest room-temperature saturation magnetostriction among non-rare-earth compounds and a high Curie temperature (T₍c₎ ∼ 780 K), properties that are critical to a wide range of industrial and medical applications. Neutron spectroscopy  ...

Single-chain polymer nanoparticles for oil solubilization

We report on the oil solubilization of amphiphilic single chain nanoparticles (SCNPs) based on random copolymers composed of oligo(ethyleneglycol) methacrylate (OEGMA) and anthracene methacrylate (AnMA). Small-angle X-ray scattering (SAXS) combined with molecular dynamics simulations reveal  ...

Hydrogen bonding exacerbates viscoelasticity of amino acid– and betaine surfactant self-assemblies

Many day-to-day materials rely on formulations of surfactants to control flow, texture and application. Inspired by the pairing of bases between DNA strands, we demonstrate enhanced control  ...

In-situ neutron tomography study of a dehydrating and hydrating packed bed for thermochemical heat storage

SINQ

To study the heat and water vapor transport and reaction kinetics in a packed bed of thermo-chemical material on both reactor and tablet level, an in-situ neutron imaging study of a dehydrating and subsequently hydrating packed bed consisting of cylindrical K2 CO3 tablets was performed at the Paul Scherrer Institute ...

Field-Induced Magnon Decay, Magnon Shadows, and Rotonlike Excitations in the Honeycomb Antiferromagnet YbBr3

SINQ

The search for new quantum many-body phenomena in magnetic materials has a strong focus on highly frustrated systems and the resulting quantum spin-liquid state. However, even unfrustrated magnetic materials show a multitude of unconventional features in their spin excitation spectra. By using the synergy of ...

Generating structured foam via flowing through a wire array

SINQ

Efficient manufacturing methods could unlock foams with tailored, anisotropic properties. Conventional foam production methods rely on the self-arrangement of bubbles, typically leading to isotropic materials, or involve intricate additive layering processes. This study presents a simple, passive technique to modify the foam structure. A set of thin parallel wires ...
