Summary: Reverse poloxamines are important building blocks that can be assembled into useful biocompatible microstructures by saccharide excipients. Glucose and sucrose have a positive effect on the micellization of reverse poloxamines, with sucrose being more favorable. Furthermore, pH conditions can convert the micelles from nonionic to cationic, opening new opportunities for controlled assembly and clustering of reverse poloxamines.

Summary: The aggregation behavior of sodium dodecyl sulfate (SDS) in the presence of increasing concentrations of selected sodium 1-alkylsulfonates was studied. The critical micelle concentration (CMC) of SDS was determined, and the micellar aggregation numbers (Nagg) of the surfactant were obtained. The thermodynamic parameters of micellization were determined and compared. It was found that SDS was significantly affected by the alkyl chain length and concentration of the selected sodium 1-alkylsulfonates.

Summary: Novel cationic gemini surfactants with two amide groups and variable alkyl chain lengths were synthesized and characterized. The critical micelle concentration of the surfactants was determined and correlated with interfacial area, micelle ionisation degree, and thermodynamics properties. The formation of small spherical micelles was confirmed by particle size analysis, and the zeta potential of the surfactants increased with longer alkyl chain lengths. The antimicrobial activity of the surfactants showed a dependence on alkyl tail length, with the short-chain surfactant exhibiting the highest efficiency.

Summary: In this study, we comprehensively characterized surfactin, a cyclic lipopeptide produced by Bacillus subtilis. We investigated its production, purified the homologues (C-12, C-13, C-14, C-15), and studied their physicochemical properties. We found a relationship between the structure and properties of surfactin, providing valuable insights for understanding its biological significance and potential applications in various industries. The methodology developed in this study can also be applied to other cyclic lipopeptides, facilitating a better understanding of their structure-properties relationship.

Summary: The study demonstrates that compared to single surfactants, mixed systems have higher surface activity and more attractive interactions. Micellization of the mixed system is an enthalpy-driven spontaneous process, and the self-assembled structures can be effectively regulated by changing the mixing ratio.

Summary: To explore the functions of glycosylation in bovine milk, the glycosylated and unglycosylated forms of kappa-Casein B were purified and analyzed for their amyloid fibril formation, morphology, oligomerisation states, and protein structure. It was found that the two forms of kappa-Casein B had similar size aggregates, but the glycosylated form had a higher amyloid fibril formation rate and different fibril morphology compared to the unglycosylated form. Glycosylation did not affect the polarity or interactions between protein molecules in the native form, but it did influence the protein folding patterns and fluorescence intensity. Overall, these results highlight the importance of glycosylation in the modulation of aggregation states and formation of amyloid fibrils from intrinsically disordered proteins.

Summary: This study investigated the behavior and distribution of water molecules in different types of ionic liquids (ILs) using molecular dynamics simulations. It was found that water molecules tend to aggregate in hydrophobic ILs, while the introduction of a hydrophilic anion significantly influences water aggregation. The results provide valuable information for understanding the mechanism of water aggregation in mixed ILs and offer a simple strategy to tune the properties of ILs and improve their performance in electrical double layer capacitors (EDLCs).

Summary: This study investigates the solubility and permeability of umifenovir (UMF) in different buffer solutions, as well as the impact of pluronic F-127 (F-127) and ethanol (EtOH) on these properties. The results show that UMF has higher solubility in acidic medium compared to alkaline medium. The presence of F-127 micelles and ethanol enhances the solubility of UMF. However, ethanol reduces the stability of the system. Moreover, ethanol increases the permeation of UMF through cellulose membranes, but excessive ethanol content can reduce this effect.

Summary: The rheological behavior of aqueous solutions of biocompatible polymer HPC in the presence of cationic CTAB and nonionic Tween 40 has been investigated. Steady-state bulk experiments show two distinct regions in the rheogram, while dynamic experiments indicate a decrease in the stability of HPC hydrogels with increasing surfactant concentration. Interfacial shear tests reveal a non-Newtonian dilatant behavior at the solution-air interface and two distinct dilatant regions separated by a Newtonian region at the solution-soya oil interface. The strength of films formed at the two interfaces decreases with the increase of surfactant concentration, indicating stronger interaction between HPC and CTAB than Tween 40.

Summary: The development of hybrid formulations incorporating hydrogels, antioxidants, and nanoemulsions containing polyunsaturated fatty acids is in high demand. In this study, we formulated quercetin-loaded oil-in-water nanoemulsions using surfactants such as Tween 20 (nonionic), sodium lauroyl sarcosine (anionic), and 3-(N,N-dimethylmyristylammonio)-propanesulfonate (zwitterionic) to control autoxidative degradation of linoleic acid. The nanoemulsions with anionic and zwitterionic surfactants exhibited better control of lipid peroxidation at 37 degrees C, with droplet sizes less than 200 nm. The hybrid alginate capsules derived from these formulations showed good release of quercetin and scavenging activity against DPPH radicals, making them robust and suitable for applications in the food and pharmaceutical industries.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
