Summary: The efficiency of electrocatalytic water splitting can be improved by integrating light-absorbing semiconductor materials into the electrocatalytic network using the photogenerated-carrier-driven strategy. A MgCo2O4@WO3 core-shell heterostructure was constructed to effectively eliminate the spatial disparity between photocatalytic and electrocatalytic components, enhancing light absorption and electron transfer. Under solar illumination, the electrocatalytic activity of MCW CSHS is significantly improved, showing potential for efficient H2 production by EWS.

Summary: Photocatalytic pollutant degradation coupled hydrogen generation via water splitting utilizing solar energy is a promising method for addressing environmental pollution and energy shortage. However, the limited utilization efficiency of solar energy and quick recombination of photogenerated carriers have hindered its application. In this study, a 0D Bi3TaO7 nanodots-decorated 3D ZnIn2S4 nanoflowers photocatalyst was synthesized for efficient simultaneous photocatalytic degradation of antibiotics and hydrogen generation. The relationship between S-scheme heterojunction photocatalysts and photocatalytic pollutant degradation coupled hydrogen evolution will be discussed, along with a careful examination of the interfacial transfer mechanism.

Summary: This study focused on the collection performance and sorption mechanisms of decaethoxylated stearylamine (DSA) as a high-selectivity hornblende collector. It was found that DSA efficiently collected hornblende, but had a poor collecting ability for siderite. The selective collection mechanisms of DSA for hornblende were attributed to electrostatic adsorption and hydrogen bonding interaction, leading to efficient desiliconization of the siderite flotation.

Summary: Studies have shown that the introduction of GO and MOF nanofillers into epoxy resin significantly improves its mechanical, thermal, anti-corrosion, and flame-retardant properties. Modifications of GO via MOFs can help avoid negative effects and enhance positive effects of the nanofillers. Introduction of GO-MOF nanohybrids can greatly improve the flame-retardant properties of epoxy resin, as well as enhance its anti-corrosion stability and adhesion strength.

Summary: Nanoscratch tests on GaN single crystals revealed that crack-free plastic deformation could be achieved along different zone axes, with deeper penetration depth and less phase transformation along the [11-20] zone axis. Higher stress along the [1-100] zone axis induced more phase transition from hexagonal system to cubic system. This study enhances understanding of the anisotropy dependence of material removal and damage mechanisms in GaN crystals.
