Summary: A novel method for monitoring mineral content of drinking water using responsive complex emulsions was reported, showing changes in droplet morphology to reflect variations in surfactant effectiveness due to metal cation addition. The study demonstrated that salt concentration and valency can influence the extent of droplet response, with divalent cations resulting in a more pronounced response. This device concept may provide a simple and cost-effective alternative for rapid monitoring of water hardness levels.

Summary: The aim of this study was to develop a rapid and convenient fluorimetric method for analyzing lomefloxacin. The method utilized the complex formation between the drug and aluminum ion to produce a highly fluorescent product. The addition of sodium dodecyl sulfate further enhanced the fluorescence intensity, which was measured at 429 nm after excitation at 332 nm. The relationship between emission intensity and lomefloxacin concentration was linear from 10-130 ng mL-1, with a correlation coefficient of 0.9996. The method demonstrated high accuracy and reliability in quantifying the drug in tablet formulations and real human plasma.

Summary: The rheological properties of CO2 hydrate slurries with and without the surfactant SDS were studied. It was found that dissolved CO2 actively participated in the nucleation and growth of hydrate crystals at higher pressures. The addition of SDS reduced the peak and steady-state viscosities of the slurries and exhibited pseudoplastic behavior. The presence of SDS also delayed the dissociation of CO2 hydrates and improved their stability and flowability.

Summary: We report the synergistic effect of microbial cyclic lipopeptide surfactin (SF) and petroleum-derived surfactant sodium dodecyl sulfate (SDS). Addition of a small amount of SF (0.1 mol %) reduces the critical micelle concentration (CMC) of SDS, minimizing SDS consumption without loss of surface activity. Surface tension measurement and nuclear magnetic resonance spectroscopy indicate attractive interactions between SDS and SF, with an extremum observed at a mole fraction of 0.7.

Summary: In this study, the removal of dodecyl sulfate (DS) ions bound to myoglobin protein was attempted using sodium cholate (NaCho). The restoration of the secondary and tertiary structures of myoglobin disrupted by sodium dodecyl sulfate (SDS) was achieved by the removal of DS ions. The cooperative action of NaCho and SDS was observed in disrupting the secondary and tertiary structures at low concentrations of both surfactants.

Summary: Recently, halide perovskites, especially all-inorganic CsPbBr3, have gained increasing attention in the field of photocatalysis due to their superior optoelectronic properties and thermal stability. However, there is limited research on their application in thermocatalysis and photo-thermocatalysis. In this study, a core-shell heterojunction composed of CsPbBr3 nanoparticles encapsulated with a 2D C3N4 (m-CN) layer was rationally designed. The results showed that m-CN@CsPbBr3 significantly improved CO2 capture and charge separation, and effectively drove the thermocatalytic reduction of CO2. When coupled with light, the activity for CO2-to-CO reduction was further enhanced, surpassing that of pure photocatalysis and thermocatalysis. This work expands the application of halide perovskites and provides guidance for utilizing perovskite-based catalysts in photo-assisted thermocatalytic CO2 reduction.

Summary: The currently dominant cathode material Li(NixCoyMnz)O-2(NCM, x + y + z = 1) in lithium-ion batteries exhibits higher energy density with increasing nickel content, but it also suffers from stronger interface reactions with the electrolyte and worse safety performance. Single crystal cathode materials have advantages such as fewer grain boundaries, higher density, and suppressed microcracks, leading to reduced interfacial side reactions and improved volumetric energy density and safety performance. In this study, a pulse high-temperature sintering (PHTS) strategy is reported to prepare single-crystal Li(Ni0.9Co0.05Mn0.05)O-2 (SC-NCM90), which shows enhanced tap density and thermal stability compared to spherical NCM90 particles.
