Summary: Proteins easily self-assemble into different aggregates during processing, such as nanoparticles and fibrils, showing strong interfacial activity at the oil-water interface. By controlling heating temperature and pH, beta-lactoglobulin aggregates were prepared in solution and characterized for their surface properties. The study demonstrated that beta-lg thermal aggregates exhibit excellent emulsification ability and significant impact on fat digestion in food emulsions.

Summary: The study investigated the behavior of untreated and chemically hardened gliadin nanoparticles at oil-water interfaces. It found that untreated GNPs formed cohesive and deformable viscoelastic films with stronger interactions, suggesting their ability to effectively interact with oil droplets. These results highlight the importance of particle deformability and protein mobility for forming strong interfacial films in emulsions.

Summary: This study developed a new type of reverse demulsifier synthesized by modifying polyacrylates. The PMD1, prepared with methyl acrylate as monomer, showed good water solubility and high demulsification efficiency. Various experiments revealed that the demulsification ability of PMD1 was attributed to the synergistic effect of cationic group adsorption bridging and acrylate group breaking the oil/water interfacial film.

Summary: An ordered mesoporous ceria, mpCeO(2), was synthesized using nanocasting, followed by strong electrostatic adsorption to prepare Ni nanoparticles encapsulated in mpCeO(2) for CO2 methanation. The Ni/mpCeO(2) catalyst showed significantly improved activity and selectivity compared to conventional CeO2-supported Ni catalyst, with the encapsulated structure and highly dispersed Ni nanoparticles playing key roles. Additionally, the mesoporous structure inhibited metal sintering, leading to excellent stability of the catalyst.

Summary: The study investigates the interfacial and bulk properties of oil-in-water emulsions stabilized by glycyrrhizic acid (GA) and cellulose nanocrystals (CNC) at different ionic strengths, indicating a synergistic effect between GA and CNC for stabilizing the emulsion systems. Complexation of GA and CNC via hydrogen bonds and intermolecular interactions is observed, leading to network formation and stabilization of the emulsions. The results provide evidence of the importance of appropriate concentrations of GA, CNC, and NaCl in achieving synergistic stabilization of the emulsions.

Summary: Betaine, specifically linear alkylbenzene sulfonate betaine (ASB), has been studied as a surfactant for enhanced oil recovery (EOR). The interfacial properties of ASB were characterized using various methods, and it was found that the difference in interfacial tension had a greater impact on EOR than the interfacial film strength of betaine.

Summary: This study demonstrates a significant enhancement of photocatalytic activity in graphitic carbon nitride (g-C3N4) by fabricating g-C3N4/ND nanocomposites. The optimized g-C3N4/ND nanocomposites exhibit excellent stability, reusability, and more than two times greater RhB degradation rate compared to g-C3N4. The enhanced photocatalytic activity is attributed to the interfacial effect between g-C3N4 and ND, which reduces electron-hole recombination and promotes charge-separation efficiency.

Summary: This paper presents a combined photographic and thermal study of interfacial behavior during boiling of liquid Nitrogen (LN2) over water surface, with observations of film boiling and LN2 drop icing. The Rayleigh-Taylor instability criterion is used to differentiate between bubbling regimes and analyze the N(2) vapor cloud generated over the drop. Sub-surface boiling phenomenon is also reported through experiments on base fluids other than water.

Summary: The present study investigates the interfacial tension between FeMn alloy and slags of different compositions and basicity. The results show that the interfacial tension increases with the slag basicity, and the addition of Al2O3 to the slag with basicity of 0.8 and 1.2 increases the interfacial tension. Furthermore, EPMA analysis reveals the formation of a metal-slag emulsion at lower basicities due to chemical reactions, partial reduction of SiO2 in the slag, and the mass transfer of Si across the metal-slag interface.

Summary: This study investigates the application prospects of bio-based sustainable natural ester as an electrical equipment insulation, focusing on the use of nanotechnology for improving its electrical and physical and chemical properties. The results show that the KH550 surface modified nano-TiO2 has a superior effect on improving the electrical properties of the insulating oil compared to nano-TiO2. The amino and silicon hydroxyl groups on the surface of KH550-TiO2 carry strong positive electrostatic potential, which enhances the dispersion of KH550-TiO2 in natural esters.

Summary: This study investigated the preparation and behavior of a multiphasic and multi-sized lignocellulose-based suspension (LBS) at the O/W interface using a green method. The LBS, composed of lignin-containing microfibrils (LMFs), lignin-containing cellulose nanofibers (LCNFs), and lignin nanoparticles (LNPs), was obtained through mechanical fibrillation and high-shear treatments. The synergistic irreversible adsorption of LCNFs and LNPs on the droplet surface restricted coalescence and created a stable interface, while the droplets filled in the LMFs network to form a strong fiber-droplet network structure. The study also demonstrated the ability of the internal droplets to support the fiber network under shear force and regenerate the fiber-droplet network after destruction.

Summary: The tribological behavior of Polyimide (PI)-MoS2 composite, pure PI, and sputtering MoS2 film under RTvacuum and cryogenic-vacuum was investigated. Low temperature increased the friction coefficient of PI-MoS2 and pure PI, while it had the opposite effect on sputtering MoS2 film. The friction interface was influenced by water under cryogenic conditions, leading to the formation of intermolecular hydrogen bonds that restricted the formation of highly oriented shear layers.
