Summary: This study reveals that a peptide derived from mussel adhesive protein can form coacervates in seawater conditions. The hydrogen bonding interactions mediated by dopamine and glycine are important for the coacervation process. The properties of the coacervates can be controlled by adjusting the pH and salt concentration of the solution, and the coacervate undergoes a liquid-to-gel transition induced by pH change, which can be used for underwater adhesive applications.

Summary: In this study, a new environmentally friendly dipping system was developed to strengthen the interfacial adhesion between aramid fiber and rubber. Inspired by mussel adhesion protein and mimicking adhesive molecule, the system achieved a comparable level of adhesion force to traditional resorcinol-formaldehyde-latex dipping system, while avoiding the use of harmful materials. Additionally, atomic force microscope was used for the first time to quantitatively characterize the modulus of the transition layer between the fiber and rubber. These findings provide new insights into the interfacial design and development of aramid fiber/rubber composites.

Summary: This study successfully improved the interfacial adhesion and UV resistance of PBO fibers in epoxy resin composites by growing TiO2 nanoparticles on the fiber surface in situ using mussel-inspired PDA as a reaction platform. The modified fibers showed enhanced interfacial shear strength, increased surface roughness, improved wettability, enhanced thermal stability, and resistance to hygrothermal aging. The compact TiO2 coating on the surface also led to excellent UV resistance.

Summary: In this study, a water-responsive dry robust tissue adhesive PAGU tape was developed through fast UV-initiated copolymerization of acrylic acid, gelatin, and hexadecenyl-1,2-catechol. The adhesive tape showed strong cohesive mechanical properties and strong interfacial adhesion bonds. It could conform to wet tissue, quickly dry the tissue surface and form high interfacial toughness interfacial bonding. Furthermore, it was easily detached by treating with aq. urea solution. This research provides an efficient method for producing conformable, tough, and easy detachable wet bioadhesive tapes.

Summary: Adhesive bonding plays a crucial role in various fields like mobility, dentistry, and electronics. However, the understanding of interfacial phenomena in adhesive bonding is still limited, making it difficult to select surface treatment and adhesive types. In this study, the authors investigated the roles of chemical interactions and mechanical interlocking in adhesive bonding between epoxy/amine adhesive and two types of aluminum adherends. They found that protonation of amino groups on the adhesive side resulted in an interfacial dipole layer, which increased the interfacial fracture energy. Furthermore, mechanical interlocking from surface roughness further enhanced the fracture energy. This study provides insights into the adhesion mechanism at the epoxy adhesive/aluminum interface.

Summary: Interactions of electronic and vibrational degrees of freedom play a crucial role in understanding excited-state relaxation pathways of molecular systems at interfaces and surfaces. The development of interface-specific two-dimensional electronic-vibrational sum frequency generation (2D-EVSFG) spectroscopy reveals strong vibronic couplings and the relaxation process in photoexcited interface-active molecules. Time-dependent experiments show that the relaxation of the locally excited state is strongly coupled with specific high-frequency modes, leading to the transition to a lower excited state.

Summary: This study developed a green method of ultrasound-assisted extraction coupled with gas bubble flotation for extracting fi-amyrin from Dischidia major. The solvent system used was water:ethanol (9:1) and cationic surfactants were employed to improve the adsorption of fi-amyrin onto the air/liquid interface during flotation. High-performance liquid chromatography with spectrophotometric detection was applied to quantify the fi-amyrin content in D. major and its extracts. The foam layer collected from flotation showed high selectivity toward fi-amyrin, and the product content increased significantly after removing surfactants from the solution.

Summary: Surfactants play a critical role in various areas due to their characteristic adsorption property and surface activities. Recent studies have controversially proposed the existence of sub-monolayer adsorption of surfactants at the air/water interface, supported by experimental evidence such as laser scattering experiments. This work provides strong evidence for the presence of sub-monolayer adsorption and suggests it can be further elucidated with other intrinsic surface-sensitive techniques.
