Enhancing the strength of metallic materials usually compromises their ductility since both properties are intrinsically decided by chemical bond strength but with opposite dependencies. Despite great effort via microstructural regulation, tackling the strength-ductility paradox in metals and alloys remains a challenge. [...]

Concentration polarization (CP) is determined by neutron transmission in a reverse osmosis (RO) system consisting of two cells, one with and the other without an RO membrane, to get the net neutron response for the feed solution in front and far from the membrane separately. The aqueous feed was a dilute solution of NaCl and GdCl3. [...]

Fuel-driven transient materials that can temporally adjust their mechanical properties are ubiquitous in living systems, enabling biological functions to be maintained far from equilibrium. While numerous biomimetic transiently stiffened materials have been developed, their low stiffened moduli (typically in the kPa range) severely restrict their practical use in load-bearing applications. [...]

A site-selective 27Alnuclear magnetic resonance (NMR) study is carried out on the Kondo lattice compound CePtAl4⁢Ge2, which crystallizes in a rhombohedral lattice with quasi-two-dimensional Ce layers forming a triangular lattice network. Two inequivalent Al sites, Al(1) and Al(2), are unambiguously assigned by comparing measured nuclear quadrupole parameters with electric field gradients obtained from electronic structure calculations. [...]

This study investigates the performance of a new compact (55 cm × 56 cm × 48 cm) in situ spin-exchange optical pumping 3He neutron spin filter (NSF) system developed at the China Spallation Neutron Source. The enclosed NSF cell, filled with 3He at 2.53 bar, achieved an initial 3He polarization of approximately 60%. [...]

Centrosymmetric compounds which host three-dimensional topological spin structures comprise a distinct subclass of materials in which multiple-𝐪magnetic order is stabilized by anisotropy and bond frustration in contrast to the more common path of antisymmetric exchange interactions. Here we investigate static and dynamic magnetic properties of the cubic perovskite SrFeO3—a rare example of a centrosymmetric material hosting two types of topological spin textures: skyrmionlike and hedgehog-lattice phases. [...]

The Airy wave packet is a solution to the potential-free Schrödinger equation that exhibits remarkable properties such as self-acceleration, nondiffraction, and self-healing. Although Airy beams are now routinely realized with electromagnetic waves and electrons, the implementation with neutrons has remained elusive due to small transverse coherence lengths, low fluence rates, and the absence of neutron lenses. [...]

Artificial irradiation is one of the most important methods used to enhance the colour of gem materials. The irradiation time is much shorter, and the energy dose is often much higher, than would occur in nature, but the treatment has been impossible or very difficult to identify since both laboratory and natural irradiation processes involve the same colouration mechanisms. [...]

This study assesses the suitability of commercial dyed polymethyl methacrylate (PMMA) dosimeters for high-dose radiation applications extending into the hundreds of kilograys. Three PMMA dosimeter types (Gammachrome YR+, Amber 3042, and Red 4034) were investigated using both online and post-irradiation optical transmission measurements in the visible spectral range. [...]

The Photon and Neutron Experimental Techniques (PaNET) ontology was released in 2021 as an ontology for two major European research infrastructure communities. It provides a standardized taxonomy of experimental techniques employed across the photon and neutron scientific domain, and is part of a wider effort to apply the FAIR (findable, accessible, interoperable, reusable) principles within the community.
