Barely larger than a fingernail, the miniature Roman box lock from the 3rd or 4th century AD
Barely larger than a fingernail, the miniature Roman box lock from the 3rd or 4th century AD is skilfully crafted out of gold. The iron mechanism inside remained hidden for a long time because conventional imaging techniques were thwarted by the dense gold casing. It was only with the help of neutron tomography at PSI that the box lock could finally be deciphered non-destructively. © LWL/S. Brentführer

Generating structured foam via flowing through a wire array

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 ...

Discovery of Nodal-Line Superconductivity in Chiral Crystals

Chiral crystals, whose key feature is the structural handedness, host exotic quantum phenomena driven by the interplay of band topology, spin-orbit coupling (SOC), and electronic correlations. Due to the limited availability of suitable chiral-crystal materials, their unconventional superconductivity (SC) remains largely unexplored. 

Here, the discovery ...

Ferroaxial density wave from intertwined charge and orbital order in rare-earth tritellurides

The discovery of the axial amplitude mode—commonly referred to as the Higgs mode—in charge density wave systems, such as rare-earth tritellurides, indicates the presence of a hidden order. A theoretical study proposed that this axial Higgs mode arises from a hidden orbital texture of the charge density wave, which produces a ferroaxial charge order.

However, experimental evidence ...

Swiss Spallation Neutron Source SINQ

Neutron scattering techniques are highly versatile and powerful tools for studying the structure and dynamics of condensed matter. A wide scope of problems, ranging from fundamental to solid state physics and chemistry, and from materials science to biology, medicine and environmental science, can be investigated with neutrons. In addition to scattering, non-diffractive methods like imaging techniques allows for non-destructive inspection of materials and components, providing information on their internal structure, composition, and integrity with growing relevance also for industrial applications.
