Summary: Metal hydrides are a class of compounds that are used to create various functional materials. Neutron diffraction is necessary to study their structural characteristics due to the low scattering power of hydrogen for X-rays. In this study, a new strontium nitridoborate hydride, Sr-13[BN2](6)H-8, was synthesized and its crystal structure was determined using X-ray and neutron diffraction. The presence of anionic hydrogen within the structure was confirmed using MAS NMR and vibrational spectroscopy. Quantum chemical calculations supported the experimental findings. Sr-13[BN2](6)H-8 expands the family of nitridoborate hydrides and opens up possibilities for new and interesting materials.

Summary: Intermetallic metal hydrides are essential for hydrogen storage, but those with higher storage capacities are still needed. Neutron vibrational spectroscopy (NVS) was used to study LaNiInHx and CeNiInH1.4, revealing close vibrational features between paired H atoms when x > 0.67. In contrast, no close H contacts were found in CeNiSnH, CeNiSnH2, and CeNiSnD2, demonstrating differences in hydrogen dynamics between the compounds.

Summary: A recent screening study identified apilimod as effective against SARS-CoV-2 virus and tetrandrine showed synergy with remdesivir. The rotational dynamics of methyl groups in apilimod and tetrandrine are faster than in remdesivir due to reduced energy barriers, which may impact their bioactivity. Screening studies based on computed potential energy profiles can help identify promising drug candidates within a drug class.

Summary: The anharmonic phonon behavior in zirconium hydrides and deuterides has been investigated using inelastic neutron scattering and lattice dynamics calculations within the framework of density functional theory. The study found that anharmonicity in these materials originates from deviations of hydrogen potentials from quadratic behavior in certain directions and is apparent for higher-order excited vibrational states. Convolution of the eigenfrequencies with the instrument resolution qualitatively describes the anharmonic peaks in the experimental data.

Summary: The structure and dynamics of crystalline 4-(dimethylamino) benzaldehyde (4DMAB) were studied using INS spectroscopy combined with periodic DFT calculations. The experimental and calculated spectra showed excellent agreement, allowing for reliable assignment of INS bands. The simulated spectrum accurately described the external phonon modes and low-frequency molecular vibrations. Crystal field splitting was observed for modes assigned to the dimethylamino group. The torsional motion of methyl groups was analyzed, and specific methyl groups were identified based on four individual bands. The torsional frequencies of these methyl groups fell within a range similar to that observed for methyl groups bonded to unsaturated carbon atoms. The hybridization state of the X atom in X-CH3 seemed to be crucial in determining the methyl torsional frequency.

Summary: Lattice dynamics in organic ferroelectric PhMDA have been studied using inelastic neutron scattering (INS) spectroscopy and first principles calculations. The INS spectrum's prominent features are mainly from the normal modes of hydrogen bonded malondialdehyde units instead of phenyl rings. It is predicted that hydrogen bonds in the malondialdehyde units contribute more to the ferroelectric polarization of PhMDA, and any distortion of H-ions in these hydrogen bonds affects the material's ferroelectric properties.

Summary: In this study, a computational spectroscopy approach was used to analyze the inelastic neutron scattering spectra of three alkoxysilane derivatives. The results showed that incorporating non-covalent interactions in the theoretical model improved the description of the experimental band profiles. However, when considering optical vibrational techniques, the monomer model provided a reasonable description and no significant changes were observed with dimer and trimer models.

Summary: The study investigated the local structure in TiVCrNbDx to explore how to destabilize the remaining sites with respect to hydrogen/deuterium occupation. The analysis revealed a body-centred tetragonal structure for partially desorbed deuteride (x = 2.2), with a higher portion of occupied sites with low valence-electron concentration. Further strategies for destabilization of the hydride were motivated based on these observations.

Summary: Quasi-elastic neutron scattering (QENS) and molecular dynamics (MD) simulations were used to investigate the dynamics of methane in H-ZSM-5 zeolite catalysts for methanol-to-hydrocarbons reactions. The study found that methane mobility was extremely high in fresh ZSM-5, and moderate levels of coke buildup had minimal effect on methane diffusion. However, highly coked samples resulted in confinement of methane to single zeolite pores with minimal long-range diffusion.

Summary: We studied the intermediate and sulfided structures of NiMo supported on Al-PILC during catalyst activation and guaiacol adsorption on the sulfided catalyst. XAFS and DFT calculations confirmed the presence of suboxides and subsulfides at first, which later transformed into MoS2 and oxygen-decorated Mo and Ni. The sulfided NiMoS2 catalyst was terminated by Mo-edge surface with 50% sulfur coverage and had a disordered Ni-edge surface. Guaiacol weakly chemisorbed via oxygen atom of OH group and physisorbed on the basal plane of NiMoS2 via van der Waals interaction.

Summary: The cracking reactions of 1-octene over H-ZSM-5 zeolite were investigated, and it was found that it follows a dual-cycle hydrocarbon pool mechanism similar to methanol-to-hydrocarbons chemistry. Higher temperatures are required for full efficiency, while lower temperatures lead to deactivation and coke deposition. Inelastic neutron scattering was used to study coke composition, revealing two distinct deactivation mechanisms depending on reaction temperature. Steam treatment of the zeolite delayed catalyst activation and resulted in increased light olefin production, with slower deactivation compared to fresh zeolite.

Summary: This study characterizes the nuclear quantum dynamics of hydrogen in Pd/cWO(3) using neutron Compton scattering and ab initio modeling. Neutron Compton scattering, with its deeply penetrating nature and high sensitivity, is a powerful tool for investigating hydrogen dynamics in bulk matrices. The analysis reveals three pools of hydrogen with different nuclear quantum dynamical behavior: hydrogen-terminated beta-palladium hydride, hydrogen in acid centers on the surface of the cubic phase of tungsten oxide, and quasi-free atomic hydrogen resulting from the hydrogen spillover process. The theoretical predictions obtained from ab initio modeling provide insights into the momentum distribution of the quasi-free atomic hydrogen. The picture of the local dynamics of the quasi-free hydrogen is consistent with the proton polaron model of hydrogen-induced coloration of bulk hydrogenated WO3.

Summary: The adsorption geometry of nitrobenzene on a 5 wt% Pd/Al2O3 catalyst is investigated using infrared spectroscopy and DFT calculations. It is found that the adsorption complex occurs vertically or tilted with respect to the metal surface, with a single Pd-O bond. However, there is a contradiction between the calculated and observed structures, which can be attributed to the difference between isolated molecule adsorption and multi molecule adsorption. Furthermore, the adsorption geometry of nitrobenzene is closely related to the high aniline selectivity observed for Pd/Al2O3 catalysts.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
