Summary: The chemical bonding and molecular deformation in thermoplastic adhesive bonding play important roles in adhesive properties. Investigating the correlation between molecular deformation and strength change is essential. The behavior at high temperatures is crucial due to different coefficients of thermal expansion in the materials. The study found that adhesive type affects the high-temperature performance, with different trends in strength change at different temperatures. The molecular deformation of the interphase follows the same trend as the strength.

Summary: This paper studied the laser surface treatment of Al alloy using sandblasting and laser ablation methods. The experimental results showed that by controlling the laser spot spacing, the bonding performance of Al alloy can be improved. Multiple laser pulses induced micro-nano composite structures, increasing the contact area and thus improving shear strength.

Summary: Surface physicochemical modifications induced by laser ablation treatment significantly improved joint strength and fracture mode, with the treatment strategy of assigning laser-treated regions on two bonding edges perpendicular to the loading direction being most effective. A theoretical model based on the Goland-Reissner equation successfully predicted joint strength with an overall error less than 10%.

Summary: This study aimed to evaluate the shear bond strength of brackets bonded to teeth etched with a conventional acid etching method in a laboratory environment using different types of adhesive agents and comparing the number of shear strokes. The results showed that the type of adhesive used had an effect on the bond strength of the bracket, with Grengloo adhesive showing higher shear bond strength.

Summary: In this study, a mechanics model based on the compliance method was developed to evaluate the shear adhesion strength of fibrillar adhesives across a wide range of aspect ratios. The model was validated through finite element analysis and revealed the different deformation regimes of the adhesive fibrils. Important parameters governing the shear adhesion were identified.

Summary: In this study, it was found that laser texturing significantly improves surface wettability of titanium alloy sheet blocks, thereby enhancing bonding performance. Using a two component epoxy adhesive binder, lap joint bonding was conducted after surface preparation. The results showed increased adhesive strength and shear lap joint bond strength compared to samples without laser texturing.

Summary: This study proposes a new biomimetic strategy to develop high bonding strength, formaldehyde-free, and petroleum resource-independent adhesive from biomass. By grafting soybean protein isolate onto oxidized demethylated lignin, a strong cohesive crosslinking network is formed, significantly improving the shear strength and toughness of the keratin-based adhesives.

Summary: The bond shear properties of UHPC-NSC were systematically investigated in this study, and factors including surface roughness, steel fibre type, and substrate strength that affect the bond strength were discussed. The results show that there is a linear relationship between the area of substrate adhered to the UHPC overlay and the bond shear strength, and substrate roughness has a significant influence on bond strength.

Summary: Traditional synthetic resin adhesives can be replaced with soy protein-based adhesives that are more sustainable, ecofriendly, and healthier. However, the low water retention of soy protein adhesives limits their widespread application. In this study, a bond-stitch topology was designed and constructed to enhance the water retention of soy protein adhesive systems, while maintaining bonding strength and coating performance. This innovative structure achieved improved water retention, bonding strength, and coating performance, making it a promising strategy for developing bio-based adhesives and hydrogels.

Summary: In this study, two ceramizable phenolic adhesives were prepared, and by adding second phase particles B4C, the bonding strength and ceramicization properties were significantly improved. B4C and ZrSi2 exhibited different oxidation reaction sequences, and the formed B2O3 liquid phase effectively enhanced the thermal resistance of the adhesive and chemically bonded with Al2O3 substrate at the interface.

Summary: The study aimed to address the long-term bonding performance of universal adhesives and provide a clinical solution with desirable bond strength to dentin. Three bonding agents were evaluated, and it was found that thermal cycling and adhesive system choice significantly affected the shear bond strength. G2-Bond Universal showed the most desirable bond strength to dentin, even after one year in the oral environment.
