Summary: In this study, the adsorption behavior of Li2Sx species on an O-doped antimonene monolayer was investigated using density functional theory (DFT) computations. It was found that the O-doped antimonene monolayer showed stronger adsorption for Li2Sx species, leading to enhanced adsorption energies. This improved adsorption effectively reduced the dissolution of lithium polysulfides and maintained the structural integrity of Li2Sx species. These findings suggest that the O-doped antimonene monolayer holds promise as an effective anchoring material for enhancing the performance of lithium-sulfur batteries.

Summary: In this paper, a monolayer of TiX2 (X = S, Se) is utilized to suppress the shuttle effect of polysulfides, thus accelerating the kinetic process of lower-order polysulfides. The adsorption energies of TiX2 for Na2Sn are better than those of common electrolytes, and the adsorption has negligible effect on the structure of Na2Sn. The anchoring behavior of TiX2 to Na2Sn does not affect the metallic properties of pristine TiX2, but it can effectively reduce the diffusion barrier energy of Na2S and improve the utilization rate of sulfur.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
