Summary: Sodium dodecyl sulfate (SDS) is proposed as a dispersant to enhance the conductive potential of nano carbon black (NCB) in cement paste. Adding 0.4% SDS effectively improves the fluidity, setting time, resistivity and mechanical strength of the nano carbon black-filled cement paste.

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: In this study, homogeneous monodisperse manganese carbonate (MnCO3) microspheres were synthesized using a co-precipitation method and their dispersion characteristics were investigated using different surfactants. The results showed that the addition of anionic surfactant SDS enabled the synthesis of MnCO3 microspheres with superior tap density. Furthermore, LiMn2O4 cathode material synthesized using spherical MnCO3 as a template exhibited excellent electrochemical performance.

Summary: This study investigates the dynamic mobility spectra of nanoemulsion drops in polyacrylamide hydrogels using electrokinetic sonic amplitude. The nanodrop radius in hydrogels is found to be similar to their nanoemulsion counterparts, with frequency-independent shear viscosity and shear modulus. The low-frequency plateau modulus systematically increases with the hexadecane volume fraction.

Summary: Here, we report a single-step synthesis of size-controlled and monodisperse, facetted ?-Al2O3 nanocrystals in an inductively coupled nonthermal plasma reactor using trimethylaluminum and oxygen as precursors, achieving phase-pure, cuboctahedral ?-Al2O3 nanocrystals with defined surface facets. Nuclear magnetic resonance studies revealed that nanocrystal surfaces are populated with AlO6, AlO5 and AlO4 units with clusters of hydroxyl groups. Nanocrystal size tuning was achieved by varying the total reactor pressure yielding particles as small as 3.5 nm, below the predicted thermodynamic stability limit for ?-Al2O3.

Summary: In this study, a thermochromic hydrogel smart window with adjustable response temperature and excellent transparency was developed. The window allows visible and ultraviolet light to pass through in high-temperature environments while blocking light in low-temperature environments to protect privacy. The hydrogel-based smart windows also have the ability to transition from transparent to opaque through electrical regulation, and show excellent cycling stability and solar modulation characteristics.

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.
