Summary: Transition-metal spinel oxides have shown great potential as high-performance electrodes for electrochemical energy storage and conversion. The irreversible or reversible spinel-rocksalt phase transformation at the oxide surface plays a crucial role in determining their performance. In this study, using Co3O4 nanoparticles as an example, the in situ atomic-scale imaging technique was employed to investigate the spinel-rocksalt transformation. It was found that the transformation is not only influenced by the oxygen vacancy formation energy but also strongly dependent on the surface polarity, with faster transformation observed at the (001) surface compared to the (111) surface.

Summary: The theoretically predicted gapped surface state of antiferromagnetic topological insulator MnBi2Te4 has been experimentally observed to have a smaller or even gapless surface state, which is caused by the defects in MnBi2Te4. The study identifies antisite Mn-Bi and Bi(Mn) as dominant defects and reveals their evolution during the phase transition from MnTe/Bi2Te3 to MnBi2Te4. It is found that complete elimination of Mn(Bi) and Bi-Mn defects in MnBi2Te4 through simple annealing is almost impossible due to high migration barrier in kinetics. Moreover, increasing concentration of Mn-Bi and Bi-Mn defects in MnBi2Te4 monolayer leads to the elimination of gap in the Dirac point-related bands, explaining the experimentally unobserved large-gap surface state. The results provide insight into the theoretical understanding of the synthesized MnBi2Te4's quality and experimentally measured topological properties.

Summary: A facile synthesis method for mixed-dimensional heterostructures via oxygen plasma treatments of 2D materials was reported. 1D/2D WO3-x/WSe2 heterostructures exhibited high molecular sensitivity with low detection limit and high enhancement factor. The ultrasensitive performance was attributed to efficient charge transfer induced by the unique structures of 1D WO3-x nanowires and effective interlayer coupling of the heterostructures, as observed by ultrafast transient spectroscopy. This work provides insights on the role of ultrafast charge transfer mechanisms in plasmon-free SERS-based molecular sensing and presents an alternative strategy for the synthesis of 1D nanostructures from 2D materials.

Summary: Rational design of pre-catalysts is crucial for efficient catalysis, especially during surface reconstruction. This study presents a surface engineering strategy to form highly active surfaces on Ni-based catalysts (NiMo) under oxygen evolution reaction (OER) conditions. In situ X-ray absorption spectroscopy and theoretical calculations demonstrate that the Fe-O-5 species anchored on Ni oxyhydroxide are easily oxidized under OER conditions, enhancing the reducibility of Ni active sites. This catalyst shows a remarkable increase in intrinsic activity and a decrease in full cell voltage compared to the NiMo and IrO2 catalysts.

Summary: By using density functional theory calculations, we have identified the stable intercalated structure and the evolution of band structures in the intercalation process of Li into bilayer graphene. Our work shows that the Dirac cone of bilayer graphene can be modulated by using the generalized N/ N/ Kekule order, which opens a gap or splits the electron and hole pocket, contributed by the Kekule-O and Kekule-Y distortion respectively. This study provides valuable insights for the investigation of Li-intercalated bilayer graphene in experiments.
