Summary: Although amphiphiles are widely used to modify interfaces, the process of interfacial reorganization remains unclear in many cases. In this study, a block copolymer system with electrostatic interactions was used to investigate the reorganization kinetics of adsorbed micelles at the water/n-decane interface. The results showed that electrostatic interactions slowed down the reorganization process, allowing for the observation of micellar flattening and merging towards a physically interconnected monolayer. The study also demonstrated that the rheological properties of the interface can be manipulated through redox reactions, and the formation of Prussian blue can stiffen the interface.

Summary: The study systematically investigated the surface activity of polyelectrolyte complex (PECs) suspensions as a function of the molar charge ratio Z. It was found that the surface tension of PECs decreases as the system approaches charge stoichiometry. The behavior of complex systems at stoichiometry is informative about the physical nature of the complexes.

Summary: In this study, the electrostatic complexation between two strong polyelectrolytes, PDADMAC and P(St-co-SSNa), was investigated. The results showed that all the anionic charges of P(St-co-SSNa) were available for complexation with PDADMAC or a cationic dye. The strength of the electrostatic interaction was found to overcome the hydrophobic effect responsible for pearl formation, and the efficiency of complexation was not significantly influenced by differences in charge density between PDADMAC and P(St-co-SSNa). Additionally, the formation of colloidal PECs was observed to occur in two distinct steps: the pairing of opposite charges to form small primary complex particles, followed by their aggregation within finite-size clusters.

Summary: Developing new biomaterials for regenerative medicine, tissue engineering, and drug delivery is an active research area. Elastin-like polypeptides (ELPs) are promising candidates due to their biosourced, biocompatible, and biodegradable properties. In this study, we synthesized 15 acyl-ELP compounds by conjugating fatty acids to different ELPs and investigated their solution behavior and drug delivery potential. The acyl-ELP conjugates formed micelles at low temperatures and aggregated above the cloud point temperature, with critical micelle concentration and size depending on the nature and length of the fatty acid and ELP block length, respectively. Hydration analysis showed that ELPs were better hydrated in micelles compared to their individual state. The acyl-ELP micelles loaded with Nile red demonstrated efficient encapsulation and release, with the largest ELP conjugated to stearic acid showing the best loading conditions.

Summary: In this study, a precatalytic system consisting of (NiX2)-X-II salts with a bipyridine-type ligand and aromatic carbonyl-based chromophores has been demonstrated to efficiently conduct cross-couplings mediated by light. Mechanistic studies revealed the reduction of a structurally defined complex into a Ni-I dimer in alcohols, while the formation of metallic ultrathin Ni nanosheets occurred in THF upon photolysis. The catalytic behavior of the system under UVA irradiation was also investigated, showing promising results in C(sp(3))-H arylation and O-arylation reactions.
