Summary: A hexameric quaternary ammonium salt surfactant with a rigid triazine spacer and six ammonium groups (Tz-6C(12)QC) was synthesized. The self-assembly behavior of Tz-6C(12)QC at different concentrations and its effects on the rheological behavior of the polyacrylamide system were investigated. The results showed that Tz-6C(12)QC exhibited excellent surface activity and had the ability to reduce the viscosity of polyacrylamide. The study also revealed the different structures formed by Tz-6C(12)QC at varying concentrations.

Summary: This paper reports the synthesis of a novel quaternary surfactant containing a hydroxyethyl group (PFPE-C) and its surface properties in aqueous solution. The study confirms that surfactants containing hydroxyethyl groups efficiently reduce the surface tension of water and that fluorocarbon surfactants have better surface activity than hydrocarbon surfactants with similar structures. The properties of PFPE-C aqueous solutions, including micellization, aggregation, air-water interfacial adsorption, and wettability, have been systematically investigated. Primary biodegradation results indicate that 19% of PFPC-C can be degraded within one week.

Summary: Ammonium in agricultural wastewater is a crucial nutrient, but its excess poses a threat. Ultrasonic waves can enhance the adsorption capacity of biochar or magnesium-loaded biochar in removing ammonium from water. The modified biochar showed improved properties and increased functional groups, leading to a more efficient adsorption of ammonium. Ultrasound also improved the electron attraction and ion exchange of biochar, resulting in higher adsorption capacity.

Summary: The structural transformations of charged spherical surfactant micelles of potassium oleate upon solubilization of water-insoluble polymer poly(4-vinylpyridine) were studied. The solubilization of the polymer resulted in the formation of complexes with necklace structure, where the polymer penetrated into the hydrophobic core of the micelles and occupied about 60% of their volume. This led to a decrease in the number of surfactant ions in the micelles. The bound charged micelles imparted water solubility to the polymer-surfactant system, behaving like a polymer coil in a good solvent.

Summary: As the concentration of nitrous oxide (N2O) continues to rise in the atmosphere, upgrading it as a potential oxygen transfer agent presents a challenge to mitigate global warming and ozone layer depletion. We demonstrate the controlled photocatalytic upgrading of N2O, releasing only benign dinitrogen (N-2) as a byproduct. The doped Ag@TiO2 photocatalyst activates N2O for controlled oxidation of phosphines, avoiding mineralization, under mild conditions.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
