Summary: Large specific surface area and oxygen defects of metal oxides have a significant impact on surface adsorption processes, and are important considerations in material synthesis. This study fabricated oxygen-deficient two-dimensional (2D) oligo-layer molybdenum trioxide (MoO3-x) nanosheets with high aspect ratio through a convenient microwave-assisted exfoliation method, and comprehensively investigated the effect of oxygen vacancies on surface adsorption using experiments and DFT calculations. The results showed that the enlarged interlayer spacings and oxygen vacancies made the 2D oligo-layer MoO3-x nanosheets promising for the adsorption of various organic molecules and exhibited superior gas sensing performance as p-type gas sensors at room temperature.

Summary: The presence of alpha-MoO3 significantly influences TiO2 photocatalytic performance and dye adsorption, with the (0 4 0) facet growth enhancing photocatalytic activity while decreasing adsorption affinity for cationic dyes. The solubility of alpha-MoO3 depends on the proportion of the (0 4 0) facet, affecting both adsorption and photocatalytic behaviors of the oxide. Evaluating photocatalytic activity of alpha-MoO3 with cationic dyes requires careful consideration due to the interaction between adsorption and photocatalytic processes.

Summary: The synergistic effect of adsorption and photothermal can be utilized for efficient pollutant treatment technologies. A porous covalent triazine frameworks modified CuO@CoMn2O4 catalyst (PCTF-CCM) was developed for the full spectrum driven photothermal degradation of toluene, achieving 100% toluene conversion and 98% CO2 yield within 40 minutes under simulated solar irradiation (optical power density = 350 mW/cm2). Oxygen vacancies play a crucial role in thermal and photothermal catalysis by improving the adsorption of pollutant gases and oxygen mobility.

Summary: The influence of deposition conditions on the optoelectronic properties of MoO3-x films is investigated in this article. It is found that increasing the substrate temperature leads to the formation of oxygen-deficient MoO3-x films with lower transmission (-30%) and higher conductivity (15-200 Ω-1cm-1). Films prepared at a substrate temperature of 400 degrees C and an RF power of 80 W exhibit crystallinity and the formation of MoO2 as well as MoO3-x, making them suitable for catalytic applications. Additionally, introducing oxygen gas during deposition results in highly transparent (-80%) and resistive (10-6 Ω-1cm-1) thin films suitable for hole transport layer applications. The stoichiometry of molybdenum oxide can be controlled by varying the film preparation conditions, thus allowing for the tuning of optoelectronic properties.

Summary: Crystal plane regulation, defect engineering, and element doping were utilized to enhance the performance of BiOCl for pollutant degradation. Iodine-doped BiOCl nanowafers with (110) crystal planes and oxygen vacancies were prepared and showed excellent photodegradation properties. The iodine-doped photocatalyst achieved high degradation efficiencies for toxic dye and antibiotic, outperforming unmodified BiOCl. The enhanced properties were attributed to the presence of (110) crystal planes, oxygen vacancies, and a modified electronic band structure.

Summary: Understanding the ion transport in concentrated electrolytes is important. This study demonstrates an enhanced ion transport of water-in-salt (WIS) electrolytes in 2D nanochannel membranes. The mechanism involves a stratification process induced by functional groups, where a free anion layer moves between two continuous water-cation layers. Lithium-ion batteries with this confined electrolyte showed improved capacity and coulombic efficiency. This work provides new insights into the ion transport mechanism in nanoconfined concentrated electrolytes and offers strategies for designing high-performance and safe electrolytes for energy and environmental devices.

Summary: In this research, a tunable splitting ratio terahertz (THz) beam splitter is demonstrated using a metasurface integrated onto a prism. The metasurface converts part of the incident wave into a cross-polarized wave and manipulates its phase, allowing it to pass through the interface even at large incident angles. The splitting ratio of the device can be adjusted by tuning the resonant response of the metasurface and varying the distance between the metasurface and the prism.

Summary: Spin-orbit coupling is the foundation for quantum materials with non-trivial topology and potential spintronics applications. The Rashba interaction is a representative model of spin-orbit interactions, and BiTeX (X = Cl, Br, I) semiconductors have been identified as exemplary Rashba materials. However, a detailed investigation of their spin textures and their relationship to local crystal symmetry is currently lacking. In this study, we directly image the spin texture of surface states of BiTeCl and find deviations from ideal behavior, including spin-polarization reversal near the Fermi level. These effects are described by higher-order contributions to the canonical Rashba model.

Summary: Currently, silicon-based anode active materials for lithium-ion batteries have gained increasing attention due to their potential high energy density. However, the replacement of graphite with silicon still faces challenges such as low coulombic efficiency, low electrode loading, and insufficient areal capacity. In this study, a silicon-graphite electrode was developed to overcome these limitations, demonstrating promising results including high coulombic efficiency, ultrahigh areal capacity, and impressive loading level. Special characterization tests further confirmed the stability of the electrode design, which was attributed to enhanced conductivity, reliable volume buffer effect, and improved ion transport and side reaction prevention.

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.
