Summary: In this study, eco-friendly plywood adhesives were prepared using soybean flour and various sugar solutions as raw materials. The optimal preparation conditions were determined by testing the bond performance, and the wet shear strength reached a maximum value when the soybean flour was mixed with a synthesized sucrose-ammonium dihydrogen phosphate solution. The curing behavior of the adhesive was studied through insoluble mass proportion and thermal analysis, and the curing mechanism was investigated using ATR FT-IR and Py-GC/MS analysis. SEM microstructure analysis showed that the cured adhesive had a more compact crosslinked structure compared to the non-soybean adhesive.

Summary: Laser surface modification involves using a laser beam to change the surface structure and chemical components of a workpiece, altering the material's physical and chemical properties. This study utilized a CO2 laser to modify poplar plywood, evaluating the processability by measuring mass loss and paint film properties. Response surface methodology was employed for experimental design, data analysis, and model creation. Results showed that laser processing parameters had a significant impact on mass loss and paint film properties, with power and feed speed playing prominent roles. The created quadratic models accurately predicted the properties variations of poplar plywood during CO2 laser modification.

Summary: A green low-temperature deposition and crystallization method was developed to uniformly coat RuO2/TiO2 nanocomposite onto cotton fabrics for efficient solar photocatalysis. The RuO2/TiO2/Cotton exhibited better visible light absorption and higher charge mobility, leading to a remarkable improvement in photocatalytic activity compared to TiO2/Cotton. The successful formation of a robust heterogeneous interface between TiO2 and RuO2 suppressed charge carrier recombination effectively, contributing to long-term stability in photocatalytic activity and high mechanical durability.
