Summary: In this study, a strategy of preparing MoxC@NC was proposed to enhance the performance of Li-S batteries. The hollow structure of MoxC@NC can confine the active materials and facilitate the ion/electrolyte penetration, while the MoxC nanoparticles in the shell can suppress the shuttling effect of LiPSs. Moreover, the defective MoxC can catalytically accelerate the conversion of polysulfides, improving the redox kinetics of sulfur species.

Summary: Lithium sulfur (Li-S) batteries hold great promise for next generation electronics and electrical vehicles due to their high theoretical capacity and energy density. However, the development of Li-S batteries is hindered by the shuttle effect and sluggish conversion kinetics of lithium polysulfides (LiPSs). This review provides a systematic analysis of the adsorption and catalytic mechanism in Li-S chemistry, discussing the role of metal oxides (MOs) as efficient catalysts and proposing oxygen vacancies and heterostructure engineering as effective strategies to improve the sluggish adsorption-diffusion-conversion process. The challenges and prospects of MOs electrocatalysts in Li-S batteries are also discussed.

Summary: A novel sheet-on-sheet architecture with abundant sulfur vacancies (Vs-ZIS@RGO) is designed by in situ growth of flake-like ZnIn2S4 on the reduced graphene oxide surface, serving as a functional layer on the separators for high-performance lithium-sulfur batteries. The sheet-on-sheet structure enables rapid ionic/electronic transfer and shortened diffusion pathways for lithium-ions, while the introduction of sulfur vacancies enhances chemical affinity and accelerates reaction kinetics. The modified separators exhibit excellent initial discharge capacity and long cycle stability, providing new insights for designing durable and efficient LSBs.

Summary: The electrochemical corrosion behaviors of Ti3SiC2/Cu composite and polycrystalline Ti3SiC2 in a 3.5% NaCl medium were investigated. It was found that the self-corrosion current density of Ti3SiC2/Cu was slightly higher than that of Ti3SiC2, but the corrosion resistance of Ti3SiC2/Cu was better than that of Ti3SiC2 under open circuit potential. The better corrosion resistance of Ti3SiC2 was due to the more stable Si layer, while Cu in Ti3SiC2/Cu reacted with Si layers to form compounds, destroying the weak interaction between Si layers and Ti-C layers.

Summary: In this paper, a large-scale stratum model and a small-scale roadway model were established using the finite element method. The optimal loading mode of the roadway model and its applicability under different roof-sidewall stiffness ratios were studied. The simulation accuracy of the roadway model was evaluated by comparing the stress and strain field distribution with those of the stratum models. The results showed that the small-scale roadway model exhibited better similarity with the stratum model under displacement load rather than stress load. Additionally, a simulation method for the small-scale roadway model suitable for the occurrence and control of surrounding rock disasters was proposed.
