Summary: This study investigated the structural, thermal, and rheological properties of a moderately concentrated (13% w/w) dispersion of sodium oleate in water for the first time. The results showed significant deviations in the phase and rheology behavior of the surfactant at this concentration, with the addition of small amounts of KCl causing a transition from elongated wormlike micelles to a gel-like viscous material. These viscoelastic aqueous dispersions of NaOL are considered excellent candidates for stimuli-responsive green materials, with their behavior depending on the presence of cosolutes such as KCl.

Summary: Ultra-long tailed zwitterionic surfactants can form aqueous wormlike elastic micelles, while shorter ones mainly exhibit spherical viscous micelles. Anionic surfactants are widely used to regulate the micellar morphology from spherical to wormlike. Systematic investigations on the molecular level are insightful for understanding the regulative mechanism of viscoelasticity. The experiment results show that sodium alkylsulfate (SAS) promotes the formation of SAS/DHSB hybrid wormlike micelles.

Summary: This study presents a novel dual-stimuli triggered wormlike micellar solution prepared by mixing cationic surfactants and sodium hydrogen phthalate. The solution can switch between a water-like state and a gel-like state by adjusting the pH and temperature. The change in flowing behavior is attributed to the microstructural transition between different micellar structures.

Summary: In this study, the mixed micellar characteristics of amino acid based mild and sulfate-free surfactant sodium cocoyl glycinate (SCGLY) in the presence of nonionic surfactants cocamide diethanolamine (CDEA) and lauryl glucoside (LG) were investigated. The presence of CDEA and LG influenced the charge and viscosity of SCGLY micelles, showing a transition from spherical to rod-like micelles at neutral pH with low to moderate viscosity. The effect of pH and total surfactant concentration on the thickening of SCGLY/CDEA/LG system was also studied.

Summary: Contrast variation in SANS was applied to localize anionic azo dye Blue in co-assemblies with cationic surfactant DTAB. Contrast matching eliminated the scattering contrast between DTAB and solvent, leaving only the signal from Blue. Results were confirmed by NOESY NMR-spectroscopy, showing interactions between Blue and DTAB and explaining the growth of DTAB micelles. The complementary use of SANS contrast matching and NMR-spectroscopy allows for the unambiguous localization of anionic dye in DTAB micelles.

Summary: The effects of SiO2 nanoparticles on the viscoelasticity of WLMs solutions were investigated, showing that micelle-nanoparticle junctions increased the contour length of WLMs to facilitate viscoelasticity. The experiments explored the impact of SiO2 NPs on zero-shear viscosity and flow activation energies of WLMs with different surfactant alkyl chain lengths. The viscoelasticity of WLMs/NPs mixture was found to be related to the hydrophobic effect between the nanoparticles and surfactant molecules in the micelle-nanoparticle junction.

Summary: Rheometry, small-angle neutron scattering, and cryo-transmission electron microscopy were used to investigate the structure and properties of mixed wormlike micelles (WLMs) of zwitterionic and anionic surfactants. The study found that the transition of linear micelles into branched micelles at increasing surfactant concentration leads to a drop in viscosity and approaches the system to the behavior of Maxwell fluid with a single relaxation time, which strongly affects the rheological properties and can be exploited in various applications of zwitterionic surfactants.

Summary: Studies were conducted to investigate the adsorption of Cs+ and Sr2+ ions on mesoporous silicas with different pore size distributions. The results showed that the adsorption of Sr2+ was not significantly affected by the pore size, while that of Cs+ was higher for silicas with larger fractions of micropores. X-ray absorption fine structure analysis revealed that both ions formed outer-sphere complexes with the mesoporous silicas. Adsorption experiments were analyzed using a surface complexation model and it was found that the equilibrium constant for the adsorption of Sr2+ was constant regardless of the pore size, whereas that of Cs+ increased with decreasing pore size.

Summary: This study introduces a new approach to construct dynamically tunable microwave absorbers with ultrawide frequency ranges and vibrant structural colors. By using atomic layer deposition (ALD) to create ZnO coatings with adjustable thicknesses on a polypyrrole/melamine foam (PPy/MF) surface, and regulating the compression ratio through a pressure-driven strategy, the electrical conductivity, electromagnetic parameters, thickness, and pore size of the ZnO-coated PPy/MF (ZnO/PPy/MF) can be effectively adjusted. Applying external pressure widens the tunable frequency range and absorption bandwidth. The ZnO/PPy/MF material is hydrophobic and exhibits self-cleaning properties. This research provides a new platform for the development of smart microwave-absorbing materials with dynamic frequency-regulating ability, brilliant structural coloration, and self-cleaning features.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
