Summary: Our study uses molecular dynamics simulations to investigate the dynamic structure factor of liquid water at the mesoscale, confirming the validity of the simulation results by comparison with neutron spectroscopy. We focus on both acoustic excitations and relaxational contributions, explaining the relaxation process dependency on momentum transfer and diffusion-driven processes. The simulations also support the assumptions of the model used to fit experimental data and qualitatively agree with the viscoelastic transition framework.

Summary: This study investigates the interplay between phonon anharmonicity and nuclear quantum effects in hexamethylenetetramine (HMT) and its deuterated counterpart (DHMT) using a combination of experimental techniques and theoretical calculations. The results show that the combined effects of isotopic substitution, temperature, anharmonicity, and nuclear quantum effects lead to systematic discrepancies between theoretical predictions and experimental data. Additionally, a significant effect known as the reverse Ubbelohde effect, where deuteration decreases hydrogen bond length in HMT, is observed.

Summary: The sensitivity of NMR spectroscopy is enhanced by DNP, where polarization is transferred from unpaired electrons to proton spins in solids. The efficiency of polarization transfer near the unpaired electron spins is unclear. Experimental results and numerical simulations show that strong hyperfine couplings to nearby protons determine high transfer rates, and fewer hydrogen atoms in TEKPol isotopologues lead to longer H-1 DNP build-up times. Based on this understanding, a new biradical, NaphPol, is designed and yields significantly increased NMR sensitivity, making it the best DNP polarizing agent in organic solvents to date.

Summary: The use of deuterocarbons is an effective method in Raman spectroscopy for studying multicomponent lipid materials and biological samples. This study investigated the Raman spectra of hydrated multilamellar vesicles and mixtures of certain lipids to identify the indicators of conformational and lateral orders. The results showed that the intensity ratio of specific peaks can be used to evaluate the conformational order of the lipid chains, and the lateral order can enhance the effect of conformational ordering.

Summary: The relation between solvation structures and transport properties of LiTFSI aqueous solutions was investigated using small-angle X-ray scattering, small-angle neutron scattering, X-ray pair distribution function measurements, and molecular dynamics simulations. It was found that solvation structures of TFSI- consist of solvent separated ion pairs and contact ion pairs, as well as cation-anion aggregates. The relaxation time associated with the anion network structure exhibited the same concentration dependence as the viscosity. This study provides insight into the correlation between solvation structures and transport properties of imide-based lithium-ion salt aqueous electrolytes.

Summary: Research has shown that introducing crystallographic shear structures in titanium oxide superlattices can decrease thermal conductivity, although the decrease is not monotonic with increasing density of shear planes. Calculation of thermal conductivity and mean free path for phonons revealed a transition from incoherent to coherent thermal conduction, with coherent interfaces formed as thermodynamically stable phases in bulk titanium oxide superlattices with nanoscale periodicity.

Summary: This study reveals that Nd2ScNbO7 exhibits long-range antiferromagnetic order, which is a result of structural disorder, instead of the commonly observed spin glass behavior. Through spectroscopic and scattering measurements, it is found that only a small percentage of neodymium ions show dispersionless gapped excitation, while the rest of the magnetic species orderly form a specific antiferromagnetic structure.

Summary: The former neutron monochromator shielding at BER-II will be relocated to FRM-II for reuse in a cold-neutron triple-axis spectrometer. As the neutron flux at FRM-II is much higher, the shielding needs to be upgraded to meet radiation protection requirements. Monte Carlo simulations were conducted to plan and optimize the upgrade, and the results show that with minor modifications and without increasing the shielding thickness, the desired dose rate level can still be achieved at the FRM-II despite the higher neutron flux.

Summary: By combining thermal transport measurements with density functional theory calculations, this study demonstrates low thermal conductivity (kappa) of approximately 1 W m(-1) K-1 in a typical layered van der Waals ferromagnet Cr2Si2Te6. The low kappa is attributed to the spin-phonon scattering and resonant magnon-phonon scattering, which can be strongly suppressed by magnetic fields. The theoretical approach used in this study may provide a generic understanding of spin-phonon scattering in various systems.

Summary: The magnetic order in Eu(Fe1-xNix)2As2 crystals is studied using polarized neutron diffraction. The Fe and Eu magnetic sublattices are found to be almost decoupled. The Eu sublattice undergoes a dramatic change in its magnetic ground state with Ni doping, transitioning from an A-type antiferromagnetic order to a canted ferromagnetic order. The lack of superconductivity in Eu(Fe1-xNix)2As2 may be attributed to the formation of in-plane ferromagnetism.

Summary: The magnetism and dynamics of the cluster glass phase in PbFe1/2Nb1/2O3 (PFN) are investigated using neutron scattering. The cluster glass phase is characterized by the lack of a preferred direction in the average magnetic spin direction and the gradual increase of the magnetic correlation length with decreasing temperature. Below approximately 50K, the spatial correlations become more short ranged, indicating increasing disorder. Neutron spectroscopy reveals fast fluctuations in the cluster glass phase, with a frequency bandwidth that mimics the correlation length. The destruction of magnetic order and the formation of the cluster glass in PFN are attributed to random molecular fields originating from conflicting interactions between clusters.

Summary: Small-angle neutron scattering measurements were conducted on the ferromagnetic superconductor EuFe2(As0.8P0.2)2 to investigate the delicate interplay between ferromagnetism and superconductivity. Large ferromagnetic domains were observed below the ferromagnetic ordering temperature TC, and additional scattering signals were found within a small temperature range below TC. These nanometer-scaled domain structures were identified as the result of the domain Meissner state, which is formed by the competition between ferromagnetism and superconductivity.

Summary: The ground-state magnetic structures of Eu2+ spins in RbEu(Fe1-xNix)(4)As-4 superconductors have been studied using neutron powder diffraction measurements. It is observed that the magnetic propagation vector of the Eu sublattice diminishes with increasing Ni doping, leading to a reduction in the rotation angle between neighboring Eu layers. The magnetic structure transitions from a helical modulation to a collinear ferromagnetic structure as the superconductivity is suppressed.

Summary: Glutaredoxin 3 (Grx3) is a redox protein that maintains structural integrity and glutathione (GSH) binding capabilities across different temperatures. This study investigates the roles of specific bonds in Grx3's structure and function, and how psychrophilic Grx3 variants adapt to cold environments. The highly conserved Arg51-Asp69 salt bridge and Gln56-His63 hydrogen bond are crucial for stabilizing the structure and catalytic activity of Grx3. Psychrophilic variants of Grx3 have adapted to cold environments by reducing GSH binding and increasing structural flexibility.
