Summary: This study compares the self-assembly of supracolloidal particles prepared with PEO-surfactant stabilized (Triton X-405) and/or PEO-grafted polymer particles. The results show that PEO-based surfactant can act as an assembly promoter of core-corona hybrid supracolloids by establishing hydrophobic interactions. The concentration of the PEO surfactant and the distribution of PEO chains on different interfaces crucially affect the assembly of supracolloids.

Summary: The addition of ethanol was found to alter the structure of perfluorooctanoate ammonium (PFOA) micelles in aqueous solutions, transitioning from a compact and slightly ellipsoidal shape to a more diffuse state, eventually breaking into smaller PFOA clusters. The increase in ethanol concentration led to a shift from co-surfactant to co-solvent behavior, impacting the formation and structure of PFOA micelles. Both experiments and simulations provided insights on achieving co-solvent conditions with other additives, which can inform strategies to modulate PFAS surfactant self-assembly in water for environmental management.

Summary: By using the interactions between nanoparticles and polymeric ligands, nanoparticle surfactants can be generated at the liquid-liquid interface, increasing the binding energy. Through a simplified model, it is found that competitive ligands can reduce the binding energy, leading to the dissociation and disassembly of the surfactants at the interface and allowing the construction of responsive and reconfigurable all-liquid systems.

Summary: Nanotubes, a fascinating self-assembled structure in supramolecular chemistry, can be produced from dinucleobase monomers through cyclotetramerization and supramolecular polymerization. The role of peripheral amide groups in guiding the polymerization process and their influence on the stabilization of macrocycles and the polymerization mechanism have been quantitatively analyzed using H-1 NMR and CD spectroscopy techniques.

Summary: Six intramolecular hydrogen bonding-induced aromatic amide foldamers were prepared through the formation of hydrazone bonds in the last step, with intermolecular halogen bonding and other types of halogen bonds designed to modulate the stacking of the compounds in the solid state. It was found that intermolecular halogen bonding can induce molecules to form extended zigzag arrays, dimeric macrocycles, or supramolecular helices, depending on the arrangement of halogen bond donor and acceptor. Additionally, polar solvents like methanol or water were shown to prevent the formation of specific halogen bonds, with some compounds forming supramolecular single helices and double helix arrays.

Summary: The self-assembly of giant molecules has attracted attention due to their fast phase separation kinetics and small feature size. However, there is not much study on multicomponent giant surfactants. In this work, a series of triblock bola-form giant surfactants with diverse functionalities were built through a modular synthetic strategy. These molecules were thoroughly characterized and it was revealed that they exhibit different phase separation scenarios.

Summary: An equilibrium state model is presented for the aggregation and adsorption of colloidal assemblies in apolar solvents, based on the step-wise aggregation response of fatty acids and monoglycerides in bio-oils. The model captures surface crowding and demonstrates the sensitivity of key observables to model parameters. Fits to molecular modelling data reveal that the model accurately reproduces chemically specific aggregate exponential distributions. The model provides an easily accessible means to estimate colloidal assembly and adsorption in oil environments.

Summary: The use of specific amphiphilic molecules can directly assemble lipids and membrane proteins to form native nanodiscs, rather than mixed micelles. Detailed investigation into the lipid bilayer integrity and membrane protein activity in these nanodiscs reveals gentle effects.

Summary: This study investigates the mixed structure of plant-derived surfactant saponins and nonionic surfactants using small angle neutron scattering. The results reveal a complex evolution in the self-assembled structure of the solution, including the transition from elongated micelle structure to micelle structure, and the formation of planar/micellar mixed phases.

Summary: Amide bonds are commonly constructed through lactone aminolysis, and this study presents 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as an effective catalyst for this reaction under mild conditions. The methodology is compatible with a wide range of lactones and amines (>50 examples), including natural products and pharmaceuticals, and it is applicable to the synthesis of bioactive molecules. Mechanistic studies reveal the involvement of acyl-TBD as the reactive intermediate in this reaction.

Summary: This study describes the reversible self-assembly of plasmonic nanoparticles capped with complementary copolymer ligands into colloidal molecules via halogen bonding interactions. The coordination number of the colloidal molecules is determined by the number ratio of complementary halogen groups on the interacting nanoparticles. The reversibility of the halogen bonds allows for controlling the formation and disassociation of the colloidal molecules and their optical properties. The engineered reversible nanostructures may have applications in sensing, catalysis, and optoelectronic devices.

Summary: Surfactants with an ester bond are easy to synthesize, can be made from natural raw materials, and have good biodegradation properties. However, labile ester bonds in some surfactants can cause stability issues at high pH. This article discusses the alkaline hydrolysis of different types of ester-based surfactants and surfactant mixtures, finding that cationic surfactants hydrolyze rapidly while anionic and nonionic ester-based surfactants are more resistant to hydrolysis.

Summary: Ternary oil-water-surfactant systems can form O/W, W/O, or bicontinuous microemulsions. Addition of a polymer can significantly affect the phase behavior, particularly expanding the middle phase microemulsion in a Winsor III system. This is practically important for enhanced oil recovery, but the scientific understanding of the role of the polymer and its interactions with the other three components in the system (oil, water, and surfactant) is still limited.
