Summary: Fluorescence in biological systems is often influenced by aromatic groups. In this study, it was found that specific hydrogen bond networks can greatly impact fluorescence, with short hydrogen bonds enhancing optical properties. This research has implications for the design of new photoactive materials with biophotonic applications.

Summary: The UV-enhanced sensing performance of a 2DPI/In2O3 based sensor for NH3 at room temperature was investigated. The composite material was synthesized using a hydrothermal method and showed sensitivity to NH3 with or without UV illumination. Characterization techniques confirmed the superior performance of the 2DPI/In2O3 sensor compared to pure 2DPI or In2O3 sensors. The presence of the 2DPI-In2O3 heterojunction and the photocatalytic promotion of 2DPI contribute to the enhanced sensing performance.

Summary: A series of Waterborne Polyurethanes (WPUs) were synthesized by utilizing molecular structure design and specific components. The effects of changes in molecular weight and content of certain components on the properties of WPUs were investigated, and it was found that higher hydrogen bond density resulted in improved strength and adhesion. When the content of a specific component reached a certain level, the film exhibited the highest values of strength and adhesion. Therefore, WPUs are suitable for applications requiring high adhesive strength, such as water-based ink binders.

Summary: A polyurethane elastomer with both mechanical strength and self-healing properties was successfully synthesized by introducing disulfide bonds and graded intermolecular hydrogen bonds. The material exhibited improved mechanical properties with an increase in the number of disulfide bonds and demonstrated outstanding self-healing capabilities. It also served as a substrate for crafting self-healing conductive devices, maintaining excellent electrical conductivity even after damage repair.

Summary: This study investigated the bond behavior between laminated veneer lumber (LVL) and flax-glass hybrid fiber reinforced polymer (HFRP) under different environmental conditions. The results showed that the exposure to hygrothermal and weathering conditions led to a decrease in the shear strength of the joints.

Summary: This study investigated the feasibility of using different solvents for preparing hot-melt pressure-sensitive adhesive (HMPSA) solutions, and found that the differences in bond strength after solvent treatment were due to physical reasons rather than chemical reactions. Solvents with similar polarity to toluene were recommended for maintaining the polymer chain relaxation of original HMPSA.

Summary: The demand for sunscreen products has been increasing in recent years due to rising cases of skin damage caused by ultraviolet radiation. Studies have shown that some materials in commercial sunscreen products are harmful to the marine ecosystem. Therefore, the development of a photoprotective and environmentally friendly screening agent has become a priority for the cosmetic industry. Calophyllum inophyllum, a seaside plant found in the Pacific Rim, is considered a potential source of biodiesel feedstock due to the high oil content of its seeds and its UV-absorbing secondary metabolites which make it a natural source for screening agents. In this study, seed extracts of C. inophyllum were found to have different chemical compositions and cytotoxicity levels depending on the solvents used for extraction, with the n-hexane seed extract showing the highest UVA and UVB absorption efficiencies. The seed oil of C. inophyllum demonstrated low cytotoxicity in in vitro cytotoxicity tests on human skin fibroblast cells, indicating its potential as a natural high-efficiency screening agent.
