Summary: The ESS in Lund, Sweden, is set to be the leading neutron source with a focus on SANS experiments. A collaboration between German universities and ESS has resulted in the development of a unified SE system to minimize downtime and ensure efficient experiment setup. The SE for foam SANS experiments has been successfully tested under ESS conditions, allowing control of foam formation, temperature, and measurement position.

Summary: This study utilized neutron reflectivity to investigate the structural changes of stimuli-responsive microgels and nanogels at hydrophobic and hydrophilic interfaces. The results showed that temperature was the primary influencing factor, while concentration played a secondary role. Hydrophobic interactions drove the conformation of the first layer at the interface, which had a key impact on the overall nanogel structure.

Summary: Possible strong first-order hadron-quark phase transitions in neutron star interiors can be detected through their imprint on gravitational waves, which can be observed with planned third-generation interferometers. Determining the existence of such phase transitions relies on the accuracy of determining the tidal deformability parameter and the model used for the equation of state of hybrid stars, which can be described using a phenomenological meta-modeling approach. Results demonstrate that a single loud binary neutron star event detected by a network of third-generation detectors could infer the presence of a phase transition at low baryon densities with an average Bayes factor of approximately 100, up to a luminosity distance of about 300 Mpc.

Summary: Soft matter systems are characterized by diverse structures and properties, and the understanding of their internal structures and dynamic behaviors is crucial for elucidating the microscopic behaviors of matter. This review highlights the applications of spin-echo small-angle neutron scattering (SESANS) and high-resolution neutron spin echo (NSE) spectroscopy in the study of soft matter systems, particularly complex fluids and biomolecular systems. NSE spectroscopy provides insights into the rheological behaviors, stability, aggregation dynamics, and interactions of various soft matter systems, and contributes to the advancements in materials science, biomedicine, and chemistry.

Summary: The coexistence of rigid and mobile sublattices in superionic Argyrodites leads to low thermal conductivity and high electrical and ionic conductivities, making it attractive for various applications. However, the understanding of the underlying lattice and diffusive dynamics in terms of the interaction between phonons and mobile ions is still incomplete. In this study, inelastic neutron scattering and molecular dynamics simulations are used to reveal that phonon softening triggers fast diffusion of Ag ions in superionic Argyrodite Ag8GeSe6. This study demonstrates the microscopic connection between soft phonons and mobile ions and provides insights into the intertwined lattice and diffusive dynamics in superionic materials.

Summary: This paper presents a methodology to optimize the hydraulic part of the design of the DND detection block. By identifying the physical parameters involved in the detection scenario, a computational model that combines fluid mechanics and neutron transport is derived. Different types of pot designs are evaluated for their impact on sodium flow velocity, DNP concentration, and detector activities, with a new coil-shaped pot design proposed for better performances in detector response to delayed neutrons.

Summary: Soft bioelectronic interfaces are a significant paradigm shift in biomedical devices, allowing for high-resolution monitoring and stimulation of physiological processes in vivo without causing tissue damage or discomfort, and can be used for prolonged periods of time. However, there are still challenges in the development and commercialization of such interfaces, such as the risk of device fracture or delamination due to continuous motion of biological tissue. This review provides an overview of experimental techniques for testing the mechanical properties and failure mechanisms of soft bioelectronic devices at the nanoscale, and discusses how this information can be used to guide the design and optimization of these interfaces and devices for healthcare, robotics, and human-machine interfaces.

Summary: This paper outlines a strategy for determining the size polydispersity of systems using small angle coherent scattering. By employing the method of moment expansion, the various central moments representing the average particle size, variance of particle size, and skewness of size distribution function (SDF) can be extracted from spectral analysis without bias. The effectiveness of this approach is demonstrated through numerical benchmarking and experimental validation using small-angle neutron scattering data obtained from L64 Pluronic micelles.

Summary: A combination of advanced in-situ experimental techniques, including neutron diffraction, acoustic emission, and electron backscattered diffraction, was used to investigate the deformation behavior of magnesium alloys. The potential and limitations of these techniques were demonstrated in a study on the influence of crystallographic texture on deformation mechanisms in a hot-rolled sheet of the AZ31 alloy. The results showed the twinning activity and its evolution, as well as the deformed microstructure, providing valuable insights into the deformation mechanisms of the alloy.
