Summary: Controllable photoisomerization of linear olefins without substituents under 625 nm light irradiation was achieved using WO3-x (W-1). By regulating the carbon chain length of the olefins and utilizing oxygen vacancies in W-1, valuable pure olefin products were obtained through this process. The high activity of olefin isomerization under light irradiation was attributed to the altered electronic structure of W-1 and the generation of unsaturated W5+ sites on the W-1 surface.

Summary: In this study, Cu-MOF and oxygen vacancy were used to improve the 1,4-dioxane (1,4-D) photocatalytic degradation efficiency of Bi2O3. The incorporation of Cu-MOF increased the specific surface area, pore structure, and reduced particle size of Bi2O3, leading to enhanced visible light utilization and improved photoelectron transfer rate. However, oxygen vacancies negatively affected the photocatalytic activity of Bi2O3. Therefore, the construction of heterojunctions using Cu-MOF can significantly enhance the efficiency of 1,4-D degradation, making Bi2O3/Cu-MOF a promising photocatalyst.

Summary: NewWave groups were simulated using a numerical wave tank based on the CFD method. Theoretical results were compared with numerical results of multiple sets of NewWave groups with varying input wave amplitudes. It was found that the theoretical focusing time and location drifted backward as the input wave amplitudes increased. Nonlinearity should not be ignored when simulating NewWave groups for large extreme wave heights. The horizontal and vertical forces on the pile-cap foundation of a sea-crossing bridge caused by the NewWave group were investigated. The research lays a solid foundation for studying the impact of NewWave on offshore structures.

Summary: The thermal transportation of pulverized semi-coke is critical for coal pyrolysis and downstream application technology. This study investigated the properties and influencing factors of semi-coke during the thermal transportation process. Compared to feed coal, semi-coke had lower total moisture (1.5%), higher calorific value (29.80MJ/kg), and comparable combustion performance parameters, making it a high-quality fuel. The characterization results revealed that semi-coke had a surface covered by a large amount of volatile matter, similar particle size with more concentrated distribution, and a higher degree of aromatization. Thermo gravimetric analysis and tube furnace tests showed that the oxidative combustion intensity of semi-coke increased with specific contact area, temperature, and oxygen concentration. Pulverized semi-coke started oxidative combustion above 350 degrees C in air atmosphere, and significant oxidative combustion occurred when the oxygen concentration exceeded 10% at a constant temperature of 350 degrees C.
