Effect of Collimation on Diffraction Signal-to-Background Ratios at a Neutron Diffractometer

Quantum Beam Science
High diffraction signal-to-background ratios (SBRs), the ratio of diffraction peak integrated intensity over its background intensity, are desirable for a neutron diffractometer to acquire good statistics for diffraction pattern measurements and ...

Absence of dynamic strain aging in an additively manufactured nickel-base superalloy

Nature Communications, 2018
Detrimental serrated plastic flow via dynamic strain aging (DSA) in conventionally processed nickel superalloys usually occurs during high temperature deformation.

Interface‐Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room‐Temperature Hopfions and Skyrmions

Advanced Materials, EarlyView.
The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.

Neutron Resonance Spectroscopy of 117Sn from1 eV to 1.5 keV

, 1999
Parity violation has been studied recently for neutron resonances in 117Sn. The neutron resonance spectroscopy is essential for the analysis of the parity violation data. We have measured neutron resonances in 117Sn for neutron energies from 1 to 1500 eV

From Molecules to Modules: Advanced Characterization of Membrane Systems

Advanced Materials, EarlyView.
Membrane technologies can enhance the efficiency and selectivity of chemical separations in energy‐water systems. Improving our understanding and design of separation membranes will require studying their properties at the molecular scale, mesoscale, and macroscale. This perspective highlights advanced characterization techniques for revealing membrane

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
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.
