Summary: Advances in the synthesis and characterization of colloidal magnetic nanoparticles have provided insights into their complex magnetic behavior and potential applications. This study focuses on the synthesis and characterization of Ni nanoparticles and reveals the presence of a non-ferromagnetic Ni phosphide shell. It also demonstrates bulk-like ferromagnetism in the Ni core and negligible interparticle magnetic interactions. These findings contribute to the understanding of synthesis-structure-property relationships in metallic magnetic nanoparticles and highlight the power of polarized SANS measurement and analysis in magnetic nanoparticle science and technology.

Summary: The MI-SANS technique is used to measure the self-diffusion constant of water, demonstrating its feasibility for observing diffusion in liquids and supporting previous measurements made with different methods. The polarized neutron technique simultaneously measures the intermediate scattering function for a wide range of time and length scales, showing potential for high-resolution time measurements. The results are compared with measurements from other techniques to assess the general applicability of MI-SANS at a pulsed source.

Summary: This study investigates the underlying mechanism of large magnetostriction in Fe-Ga alloys through in-situ magnetic small-angle neutron scattering (SANS). The results reveal that the reorientation of nanodomains relevant to face-centered-tetragonal L6 0 nanoprecipitates occurs at relatively lower fields than that of the magnetic domains, contributing to the low-field-triggered large magnetostriction. It is also found that the correlation length can be effectively tuned by simple heat-treatment, which enhances the magnetostriction without enlarging the triggering field.

Summary: Small angle neutron scattering (SANS) is a powerful tool for characterizing multi-scale structures in macromolecules, with deep penetration and H/D isotope labeling providing unique scattering capabilities. Understanding the basic principles, instrumentation, experimental skills, and data analysis methods of SANS is crucial for researchers, and the combination of SANS with other scattering techniques can provide detailed information on complex systems. With the opening of the China Spallation Neutron Source (CSNS) to users worldwide and the development of SANS instruments with various sample environments, more opportunities are now available for the SANS communities domestically and abroad.

Summary: This study investigates the incompatibility of nonionic surfactant Polysorbate 80 (PS80) with antimicrobial agent m-cresol in pharmaceutical formulation. The storage temperature, ionic strength, and component concentration were found to affect the kinetics of micelle aggregation. The cause, coalescence mechanism, and aggregate structure were revealed through small-angle neutron scattering (SANS) analysis. The phase diagram of PS80/m-cresol solution stability and the necessary component concentrations for producing stable formulations were established.

Summary: This article introduces the methods, advantages, and disadvantages of using small-angle neutron scattering (SANS) to obtain Bragg diffracted intensities and q values for crystalline structures. A comparison is made between the multichromatic time-of-flight method and the traditional quasi-monochromatic SANS method. Experimental data from high-magnetic-field measurements on magnetic vortex line lattices in superconductors are presented, demonstrating the application of these methods. The article also notes that these methods can be applied to the study of other mesoscopic crystalline structures using SANS instruments at pulsed sources.

Summary: Recent advances in protein expression protocols have allowed for the investigation of structurally complex and disordered biomolecules using small-angle scattering experiments. A modeling scheme has been developed that combines classical form factor based modeling with spherical harmonics-based formulation to accurately calculate scattering profiles from these complex samples. The scheme can account for flexible domains and other structurally elaborate components, and we demonstrate its utility through a case study on a growth hormone receptor membrane protein. We also explore how the scattering profiles vary under different contrasts and discuss the implications for data modeling.

Summary: This study demonstrated the use of contrast-matching small-angle neutron scattering (SANS) to directly probe the hydration states of aluminum adjuvants in solution. The results showed that freeze-thaw stress could lead to the dehydration and aggregation of aluminum adjuvants, while the inclusion of sucrose in samples reduced the dehydration and inhibited the formation of large aggregates. The relationship between freeze-thaw-induced dehydration and aggregation of aluminum adjuvants can explain the loss of adjuvanticity and enable more efficient development of thermostable vaccine products.

Summary: The application of neutron methods to the study of reentrant spin glasses and their transition to a canonical spin glass is discussed in this article. The focus is on two emblematic systems, namely Au1-xFex and amorphous a-Fe1-xMnx, and their unique static and dynamic properties are highlighted through experimental results. The role of small-angle neutron scattering (SANS) in unraveling the mesoscopic structure of these complex systems is emphasized. Recent SANS results performed under an applied magnetic field reveal the presence of vortex-like defects in the reentrant spin glass region up to the critical line, which vanish in the spin glass region. These defects, which only develop in a ferromagnetic medium, could be a key feature in probing the emergence of long-range magnetic order.

Summary: In this study, the magnetism of Cr8Y8 was investigated using high-frequency electron spin resonance (HF-ESR) method. It was confirmed that Cr8Y8 has an S = 12 ground state and a zero-field splitting (ZFS) due to axial magnetic anisotropy. The validity of the macrospin model was also demonstrated. This research contributes to a deeper understanding of the magnetism of Cr8Y8 and highlights the importance of the HF-ESR method in determining ZFS parameters with very small magnitude.
